6 Value Series Manual

Environment

Air surrounding the water heater, venng, and vent

terminaon(s) is used for combuson and must be free

of any compounds that cause corrosion of internal

components. These include corrosive compounds that

are found in aerosol sprays, detergents, bleaches,

cleaning solvents, oil based paints/ varnishes, and

refrigerants. The air in beauty shops, dry cleaning

stores, photo processing labs, and storage areas for pool

supplies oen contains these compounds. Therefore it

is recommended that outdoor models be used for these

locaons where possible.

The water heater, venng, and vent terminaon(s)

should not be installed in any areas where the air may

contain these corrosive compounds. If it is necessary for

a water heater to be located in areas which may contain

corrosive compounds, the following instrucons are

strongly recommended.

IMPORTANT CONSIDERATIONS FOR:

Indoor/Internal Water Heaters

• DO NOT Install in areas where air for combuson

can be contaminated with chemicals.

• Before installaon, consider where air has the

ability to travel within the building to the water

heater.

• Where possible, install the water heater in a sealed

closet so that it is protected from the potenal of

contaminated indoor air.

• Chemicals that are corrosive in nature should not

be stored or used near the water heater.

Outdoor/External Water Heaters and Vent

Terminaons of Indoor/Internal Water Heaters

• Install the water heater as far away as possible

from exhaust vent hoods.

• Install as far away as possible from air inlet vents.

Corrosive fumes may be released through these

vents when air is not being brought in through

them.

• Chemicals that are corrosive in nature should not

be stored or used near the water heater or vent

terminaon.

Damage and repair due to corrosive compounds in the

air is not covered by warranty.

Consideraon of care for your water heater should

include evaluaon of water quality.

The water must be potable, free of corrosive chemicals,

sand, dirt, or other contaminates. It is up to the

installer to ensure the water does not contain corrosive

chemicals, or elements that can aect or damage the

heat exchanger. Water that contains chemicals

exceeding the levels below aect and damage the heat

exchanger. Replacement of the heat exchanger due to

water quality damage is not covered by the warranty.

Regulaons

If you install this water heater in an area that is known

to have hard water or that causes scale build-up the

water must be treated and/or the heat exchanger

ushed regularly.

When scale build-up in the heat exchanger begins to

aect the performance of the water heater, a diagnosc

code “LC#” will display. Flush the heat exchanger to

prevent damage to it. Scale build up is caused by hard

water set at a high temperature.

You must ensure that clearances will be met and that

the vent length will be within required limits. Consider

the installaon environment, water quality, and need

for freeze protecon. Requirements for the gas line,

water lines, electrical connecon, and condensate

Freeze Protecon

Make sure that in case of freezing weather that the

water heater and its water lines are protected to

prevent freezing. Damage due to freezing is not

covered by the warranty.

Loss of freeze protecon may result in water damage

from a burst heat exchanger or water lines.

With electrical power and gas supplied, the water

heater will not freeze when the outside air

temperature is as cold as –22°F (-30°C) for indoor

models or is as cold as –4°F (-20°C) for outdoor

models, when protected from direct wind exposure.

Because of the “wind-chill” eect, any wind or

circulaon of the air on the unit will reduce its ability

to freeze protect.

The unit may be drained manually. However, it is

highly recommended that:

• drain down solenoid valves are installed that will

automacally drain the unit if power is lost.

These are available in a kit, 104000059.

• a surge protector with terminals is installed which

allows the solenoid valves to operate if the unit is

disabled due to a diagnosc code. This is

available as 104000057.

In addion, the solenoid valves should be connected

electrically to a surge protector with terminals. This

allows the solenoid valves to operate if the water

heater is disabled due to a diagnosc code.

The freeze protecon features will not prevent the

external piping from freezing. It is recommended that

hot and cold water pipes are insulated. Pipe cover

enclosures may be packed with insulaon for added

freeze protecon.

In the event of a power failure and/or gas

interrupon at temperatures below freezing the

water heater should be drained of all water to

prevent freezing damage. In addion, drain the

condensate trap and drain line.

Maximum vent length

(indoor models only)

1. Determine the number of 90 degree elbows in

the vent system. (Two 45 degree elbows count as

one 90 degree elbow.)

2. Refer to the table to nd the maximum vent

length based on the number of elbows.

Piping Requirements

Pressure Relief Valve Requirements

Install the pressure relief valve according to local

plumbing codes and these instrucons.

An approved pressure relief valve is required by the

American Naonal Standard (ANSI Z21.10.3) for all

water heang systems, and shall be accessible for

servicing.

DO NOT

• Do not plug the relief valve and do not install any

reducing ngs or other restricons in the relief

line. The relief line should allow for complete

drainage of the valve and the line.

• Do not place any other type valve or shut o

device between the relief valve and the water

heater.

MUST DO

• The relief valve must comply with the standard for

Relief Valves and Automac Gas Shuto Devices for

Hot Water Supply Systems ANSI Z21.22 and /or the

standard Temperature, Pressure, Temperature and

Pressure Relief Valves and Vacuum Relief Valves,

CAN1-4.4.

• The relief valve must be rated up to 150 psi and to

at least the maximum BTU/hr of the appliance.

• The discharge from the pressure relief valve should

be piped to the ground or into a drain system per

local codes.

• The pressure relief valve must be manually

operated once a year to check for correct

operaon.

• The relief valve should be added to the hot water

outlet line and near the hot water outlet according

to the manufacturer’s instrucons. DO NOT place

any other type valve or shut o device between

the relief valve and the water heater.

INFORMATION

• If a relief valve discharges periodically, this may be

due to thermal expansion in a closed water supply

system. Contact the water supplier or local

plumbing inspector on how to correct this

situaon. Do not plug the relief valve.

• The American Naonal Standard (ANSI Z21.10.3)

does not require a combinaon temperature and

pressure relief valve for this appliance. However,

local codes may require a combinaon

temperature and pressure relief valve.

Isolaon Valves

Rinnai strongly recommends the installaon of

isolaon valves on the cold and hot water lines

because they provide the ability to isolate the water

heater from the structure’s plumbing and allow quick

access to ush the heat exchanger. Flushing the heat

exchanger regularly is required as part of the proper

maintenance for this water heater.

Water discharged from the pressure relief valve could

cause severe burns instantly or death from scalds.

Connect Water Heater to Water Supply

Water connecons to the tankless water heater

should follow all state and local plumbing codes.

If this is a standard installaon, refer to the Piping

Diagram for Basic Installaon.

1. Plumb water supply to the tankless water heater

on the 3/4” MNPT connecon at the boom of

the unit marked “Water Inlet”, which is the cold

water supply.

2. Plumb the building hot water supply to the 3/4”

MNPT connecon marked “Water Outlet”, which

is the hot water supply.

If a pipe cover will be installed, make sure water lines

to the water heater t.

Checklist for Plumbing

□ Purge the water line of all debris and air by

closing the hot isolaon valve and opening the

cold isolaon valve and its drain. Debris will

damage the water heater. Use a bucket or hose

if necessary.

□ Ensure that hot and cold water lines are not

crossed to the unit and are leak free.

□ Ensure that a pressure relief valve is installed with

a rang that exceeds the BTU input of the water

heater model. Refer to the rang plate on the

side of the water heater for BTU input.

□ Clean the inlet water lter by closing the cold and

hot water inlet isolaon (shut-o) valves. Put a

bucket under the lter at the boom of the water

heater to catch any water that is contained inside

the unit. Unscrew the water lter. Rinse the

lter to remove any debris. Install the lter and

open the isolaon valves.

□ Check for proper water pressure to the water

heater. Minimum water pressure is 20 psi. Rinnai

recommends 30-80 psi for opmal performance.

Installaon of Gas Supply

MUST DO

• A manual gas control valve must be placed in the

gas supply line to the water heater. A union can be

used on the connecon above the shut o valve

for the future servicing or disconnecon of the

unit.

• Check the type of gas and the gas inlet pressure

before connecng the water heater. If the water

heater is not of the gas type that the building is

supplied with, DO NOT connect the water heater.

Contact the dealer for the proper unit to match the

gas type.

• Check the gas supply pressure immediately

upstream at a locaon provided by the gas

company. Supplied gas pressure must be within

the limits shown in the Specicaons secon with

all gas appliances operang.

• Before placing the appliance in operaon all joints

including the heater must be checked for gas

ghtness by means of leak detector soluon, soap

and water, or an equivalent nonammable

soluon, as applicable. (Since some leak test

soluons, including soap and water, may cause

corrosion or stress cracking, the piping shall be

rinsed with water aer tesng, unless it has been

determined that the leak test soluon is non-

corrosive.)

• Use approved connectors to connect the unit to

the gas line. Purge the gas line of any debris

before connecon to the water heater.

General Instrucons

WARNING

1. A licensed professional must install the gas

supply.

2. Turn o 120v power supply.

3. Turn o the gas.

4. Gas is ammable. Do not smoke or provide other

ignion sources while working with gas.

5. Do not turn on the water heater or gas unl all

Value Series Manual 19

Size the gas pipe

The gas supply must be capable of handling the enre

gas load at the locaon. Gas line sizing is based on

gas type, the pressure drop in the system, the gas

pressure supplied, and gas line type. For gas pipe siz-

ing in the United States, refer to the Naonal Fuel Gas

Code, NFPA 54. The below informaon is provided as

an example. The appropriate table from the applica-

ble code must be used.

1. For some tables, you will need to determine the

cubic feet per hour of gas required by dividing the

gas input by the heang value of the gas

(available from the local gas company). The gas

input needs to include all gas products at the lo-

caon and the maximum BTU usage at full load

when all gas products are in use.

2. Use the table for your gas type and pipe type to

nd the pipe size required. The pipe size must be

able to provide the required cubic feet per hour

of gas or the required BTU/hour.

Example:

The heang value of natural gas for your locaon is

1000 BTU/FT

. The gas input of the V75i is 180,000

BTU/HR. Addional appliances at the locaon require

65,000 BTU/hr. Therefore the cubic feet per hour =

(180,000 + 65,000) / 1000 = 245 FT

/HR. If the pipe

length is 10 feet then the 3/4 inch pipe size is capable

of supplying 273 FT

/HR of natural gas.

Gas Input of all gas products (BTU / HR)

Heang Value of Gas (BTU / FT

)

Cubic Feet

per Hour =

(CFH)

• Any compound used on the threaded joint of the

gas piping shall be a type which resists the acon

of liqueed petroleum gas (propane / LPG).

• The gas supply line shall be gas ght, sized, and so

installed as to provide a supply of gas sucient to

meet the maximum demand of the heater and all

other gas consuming appliances at the locaon

without loss of pressure.

• Refer to an approved pipe sizing chart if in doubt

about the size of the gas line.

Final Checklist

□ The water heater is not subject to corrosive

compounds in the air.

□ The water supply does not contain chemicals or

exceeds total hardness that will damage the heat

exchanger.

□ Clearances from the water heater unit are met.

□ Clearances from the vent terminaon / air intake

are met.

□ For indoor models, ensure you have used the

correct venng products for the model installed

and that you have completely followed the

venng manufacturer’s installaon instrucons

and these installaon instrucons.

□ For indoor models, verify that the vent system

does not exceed the maximum length for the

number of elbows used.

□ For indoor models verify that SW 1 in DIPSW 1

has been adjusted for vent length if necessary.

Refer to the secon on Maximum Vent Length.

□ For indoor models, verify that the vent pipe has a

downward slope or grade to the outside of 1/4

inch per foot (1.2°) OR if the vent pipe is sloped

toward the water heater (as some local codes

require), that a condensate collector is installed

How to use the Temperature Controller

The MC-91-2 controller is the standard temperature

controller that is supplied with the water heater. On

indoor models it is integrated into the front panel. The

MCC-91-2 controller is for hydronic applicaons requiring

higher temperatures. When the MCC-91-2 controller is

connected, these higher temperatures are available on all

controller models in the system. Refer to the secon on

temperature ranges.

DO NOT repeatedly operate the water heater and then use

a hot water tap while the controller is turned o. Operang

the water heater in this way to alternately produce hot

water may cause water to condense on the outside of

internal parts and accumulate in the water heater cabinet.

MC-91-2US

• Before operang, smell all around the appliance area

for gas. Be sure to smell next to the oor because

some gas is heavier than air and will sele on the

oor.

• Keep the area around the appliance clear and free

from combusble materials, gasoline, and other

ammable vapors and liquids.

• Always check the water temperature before entering

a shower or bath.

• Do not use this appliance if any part has been under

water. Immediately call a licensed professional to

inspect the appliance and to replace any part of the

control system and any gas control which has been

under water.

• Should overheang occur or the gas supply fail to shut

o, turn o the manual gas control valve to the

appliance.

• Do not adjust the DIP switch unless specically

instructed to do so.

• Do not use an extension cord or an adapter plug with

this appliance.

• Any alteraon to the appliance or its controls can be

dangerous and will void the warranty.

• If you install this water heater in an area that is known

to have hard water or that causes scale build-up the

water must be treated and/or the heat exchanger

ushed regularly. Rinnai provides a “Scale Control

System” that oers superior lime scale prevenon and

corrosion control by feeding a blend of control

compounds into the water supply. Damage and repair

due to scale in the heat exchanger is not covered by

warranty.

• Keep the air intake locaon free of chemicals such as

chlorine or bleach that produce fumes. These fumes

can damage components and reduce the life of your

appliance. Damage and repair due to corrosive

compounds in the air is not covered by warranty.

WARNING

Value Series Manual 31

How to Set the Temperature

While any hot water is being provided,

the temperature seng can only be

adjusted between 98° F and 110° F.

NOTICE

Check local codes for the maximum water

temperature seng allowed when used

in nursing homes, schools, day care

centers, and all other public applicaons.

NOTICE

If a newly installed unit with a controller

has not been powered for at least 6 hours

then the temperature will return to the

default seng of 104° F (40° C) if power is

interrupted.

NOTICE

There may be a variaon between the

temperature displayed on the

temperature controller and the

temperature at the tap due to weather

condions or the length of pipe to the

water heater.

NOTICE

1. If the water heater is o, press

the Power buon to turn on.

2. If the Priority light is o, then

press the “Priority buon” on the

temperature controller. The

green Priority light will glow

indicang that this controller is

controlling the temperature and

that the water heater is ready to

supply hot water. (The priority

can only be changed while no hot

water is running.)

3. Press the up or down buons to

obtain the desired temperature

seng.

All hot water sources are able to

provide water at this temperature

seng unl it is changed again at

this or another temperature

controller.

DANGER

Water temperatures over 125° F (52° C) can cause severe burns or scalding

resulng in death.

Hot water can cause rst degree burns with exposure for as lile as:

3 seconds at 140° F (60° C)

20 seconds at 130° F (54° C)

8 minutes at 120° F (49° C)

Children, disabled, or elderly are at highest risk of being scalded.

Feel water before bathing or showering.

This water heater requires a minimum ow rate to operate. This rate can be found on the specicaon page in

this manual. In some cases when you are not geng hot water or if the water alternates between hot and cold,

it is due to the water ow being below or close to the minimum ow rate. Increasing the ow rate should

resolve these problems in these cases.

If you are experiencing issues with higher temperature sengs, then reduce the temperature seng. Selecng a

temperature closer to that which is actually used at the faucet will increase the amount of hot water being

delivered to the faucet, due to less cold water mixing at the xture.

32 Value Series Manual

Seng Controller to Mute

On the MC-91-2 to eliminate the beeps when keys are pressed or to turn the beeps back on, press and hold both

the up and down buons unl a beep is heard (approximately 5 seconds).

WATER

Shut o the cold water supply to the water heater. It

is generally preferable to shut o the water to the

enre locaon if water is not going to be used.

Drain the water heater by opening the drain valves on

the cold water line and hot water line.

Open several hot water taps and remove the lter

assembly at the water inlet in order to allow room for

expansion in case there is water in the lines that

freeze.

ELECTRIC

Disconnect the power supply by either unplugging the

electrical cord or by turning o the circuit breaker to

the water heater to prevent potenal damage from

irregular power surges or interrupons.

VENT TERMINATION

Place a cover over the vent terminaon (intake and

exhaust) if it can be safely accessed. The cover should

be easy to apply and remove. This will prevent

debris, leaves, and small animals from entering the

venng and water heater which could cause air ow

issues upon return to service.

Tesng the pressure relief valve should only be

performed by a licensed professional. Water

discharged from the pressure relief valve could cause

ATTEN-

• RISQUE DE BRÛLURES. Des sores très chaudes

d’échappement et venlaon peuvent causer de

sérieuses brûlures. Restez à l’écart du chaue-eau

en fonconnement. Maintenez les pets enfants et

les animaux à distance de l’appareil.

• Les tuyaux de sore d’eau chaude quiant

l’appareil peuvent être chauds au toucher. Dans

des applicaons résidenelles, il faut appliquer une

isolaon des tuyaux d’eau chaude en-dessous de

36" (91 cm) du fait d’un risque de brûlures des

pets enfants.

• Avant la mise en œuvre, reniez tout autour de la

zone de l’appareil pour détecter une odeur de gaz. Ne

manquez pas de chercher près du plancher car

certains gaz sont plus lourds que l’air et s’accumulent

au sol.

• Gardez la zone autour de l’appareil dégagée et

exempte de maères combusbles, d’essence et

d’autres vapeurs ou liquides inammables.

• La construcon combusble concerne les closions

adjacentes et le plafond, à ne pas confondre avec les

produits et maères combusbles ou inammables.

Ces derniers ne doivent jamais être entreposés à

proximité de cet appareil au gaz ou de tout autre du

même type.

• Contrôlez toujours la température de l’eau avant de

prendre un bain ou une douche.

d’eectuer une intervenon d’entreen :

 Coupez l’alimentaon électrique en débranchant

la che du cordon secteur ou en coupant le

secteur au disjoncteur du circuit. (Le contrôleur

de température ne commande pas l’alimentaon

électrique).

 Coupez l’arrivée du gaz à la vanne manuelle, en

général elle est placée immédiatement sous le

chaue-eau.

 Coupez l’arrivée d’alimentaon en eau. Cela peut

se faire à la vanne d’isolement immédiatement

sous le chaue-eau, ou en coupant la distribuon

d’eau du bâment.

• N’ulisez que votre main pour appuyer sur le bouton

de commande de gaz ou l’enfoncer. N’ulisez jamais

d’ouls. Si la commande ne se tourne pas ou ne

s’enfonce pas à la main, n’essayez pas de la réparer

vous-même, mais appelez un professionnel agréé. Le

fait de forcer ou de tenter une réparaon peut

provoquer un départ d’incendie ou une explosion.

• N’ulisez pas cet appareil si une pare quelconque a

été immergée dans de l’eau. Appelez immédiatement

un professionnel agréé pour inspecter l’appareil et

remplacer toute pièce du système de contrôle et toute

commande de gaz qui aurait séjourné sous l’eau.

• N’ulisez pas de matériel de substuon. N’ulisez

que des pièces cerées pour aller avec l’appareil.

• En cas de surchaue, ou si il est impossible de couper

l’alimentaon en gaz, coupez au niveau de la vanne

manuelle de gaz en amont de l’appareil.

• Ne modiez pas la posion des micro-commutateurs

sauf si cela vous a été demandé expressément.

• N’ulisez pas de cordon rallonge ni d’adaptateur de

prise avec cet appareil.

• Toute altéraon de l’appareil ou de ses commandes

peut être dangereuse et annulerait sa garane.

• Une bonne venlaon est nécessaire pour un

fonconnement sûr de cet appareil.

• Assurez-vous que la venlaon de l’appareil n’est pas

bloquée ou parellement obstruée.

• Assurez-vous que par temps très froid le chaue-eau

et ses conduites d'eau sont protégées ecacement

pour éviter le gel.

Environnement

Air entourant le chaue eau, l'évacuaon et l'évent

terminaon(s) est ulisé pour la combuson et doit être libre

de tout composés qui causent la corrosion des composants

internes. Ces comprennent des composés corrosifs qui sont

trouvent dans les aérosols, les détergents, les agents de

blanchiment, les solvants de neoyage, huile de base

peintures et vernis et uides frigorigènes. L'air de beauté

bouques, magasins de neoyage à sec, laboratoires de

traitement de photos et aires de stockage des fournitures pool

conent souvent ces composés. Par conséquent, il est

recommandé que les modèles extérieurs soient ulisés pour

ces endroits lorsque c'est possible.

Le chaue-eau, l'évacuaon et l'évent terminaon(s) ne doit

pas être installé dans toutes les zones où l'air de combuson

peut contenir ces composés corrosifs. Si cela est nécessaire

pour un chaue-eau à être situés dans des zones qui peuvent

contenir des composés corrosifs, les instrucons suivantes

sont fortement recommandées.

Considéraons importantes pour:

Chaue-eau d'intérieur

• FAIRE pas les installer dans les zones où air de combuson

peut être contaminé par des substances chimiques.

• Avant l'installaon, examiner où air a la capacité de

voyager dans l'immeuble pour le chauage de l'eau.

• Lorsque c'est possible, installez le chaue-eau dans un

placard scellé an qu'elle est protégée contre le potenel

de l'air intérieur contaminé.

• Substances chimiques qui sont corrosifs dans la nature ne

doivent pas stockées ou ulisées près de chaue-eau.

Chaue-eau extérieurs et Évacuaon des terminaisons de

chaue-eau internes

• Installez le chaue-eau aussi loin que possible des hoes

de venlaon d'échappement.

• Installez aussi loin que possible des bouches d'air inlet.

Fumées corrosives peuvent être libérées par le biais de ces

évents lorsque l'air n'est pas apportée grâce à eux.

• Substances chimiques qui sont corrosifs dans la nature ne

devraient pas stockées ou ulisées près de la cessaon de

chauage ou de vent de l'eau.

Dommages et réparaon en raison de composés corrosifs dans

l'air n'est pas couvert par la garane.

Dans les facteurs à considérer pour l’entreen de votre

chaue-eau il y a l’évaluaon de la qualité de l’eau.

L’eau doit être potable, exempte de produits chimiques

corrosifs, de sable, salissures ou autres contaminants. Il est

de la responsabilité de l’installateur de s’assurer que l’eau ne

conent pas de produits chimiques corrosifs ou d’éléments

qui pourraient aecter ou endommager le chaue-eau. Une

eau qui conent des produits chimiques dépassant les seuils

montré dans ce tableau aecte et endommage l’échangeur

thermique. Un remplacement de chaue-eau résultant d’une

mauvaise qualité d’eau n’est pas couvert par la garane.

Si vous vivez dans une région connue pour la dureté de son

eau, ou pour causer des accumulaons de tartre, vous devez

traiter votre eau et/ou rincer régulièrement l’échangeur

thermique.

Quand du tartre qui s’accumule dans le chaue-eau

commence à aecter sa performance, un code de diagnosc

“LC#” va s’acher. Rincez l’échangeur thermique pour éviter

qu’il ne soit endommagé. Une accumulaon de tartre est due

à de l’eau dure avec une consigne réglée à température

élevée.

Rinnai propose le “Système de condionnement d’eau

ScaleCuer” de Southeastern Filtraon qui permet une

prévenon supérieure du niveau d’entartage et du contrôle

de la corrosion, en injectant un mélange de composés de

contrôle dans l’alimentaon en eau froide.

Vous devez vous assurer que les habilitaons seront sasfaites

et que le cloaque sera dans les limites requises. Tenir compte

de l'environnement d'installaon, qualité de l'eau et nécessité

d'une protecon de gel. On trouvera des exigences pour la

Protecon de gel

Assurez-vous que dans le cas de congélaon météo

que le chaue-eau et ses lignes de l'eau sont protégés

pour éviter le gel. Dommages causés à la congélaon

n'est pas couvert par la garane.

Perte de gel protecon peut entraîner des dégâts

d'eau d'un échangeur de chaleur de rafale ou des

conduites d'eau.

Avec l'énergie électrique et du gaz fournie, le chaue-

eau gèleront pas lorsque la température de l'air

extérieur est froide comme –22°F (-30 ° c) pour les

modèles de l'intérieurs ou est froid comme –4°F (-20 °

c) pour les modèles en plein air, lorsque le protégé du

vent directe. En raison de l'eet de « éolien », tout

vent ou la circulaon de l'air sur l'unité réduira sa

capacité de geler les protéger.

L'unité peut être drainée manuellement. Toutefois, il

est fortement recommandé que :

• Égouer down solénoïde soupapes sont installés

qui s'écoulera automaquement l'unité si de

puissance est perdue. Celles-ci sont disponibles

dans un kit, 104000059.

• un parasurtenseur avec terminaux est installé qui

permet les électrovannes à fonconner si l'unité

est désacvée en raison d'un code de diagnosc.

Ceci est disponible comme 104000057.

En outre, les électrovannes devraient être connectés

électriquement à un parasurtenseur avec terminaux.

Cela permet les électrovannes à exploiter si le chaue

-eau est désacvé en raison d'un code de diagnosc.

Les fonconnalités de protecon de gel n'empêchera

pas la tuyauterie externe du point de congélaon. Il

est recommandé que les conduites d'eau chaudes et

froides sont isolés. Boîers de couverture de tuyaux

peuvent être emballés avec isolaon pour la

protecon de l'ajout de gel.

En cas de panne de courant et / ou de l'interrupon

de gaz à des températures de congélaon de l'eau

réchaueur devrait être drainé de l'eau pour prévenir

les dommages au gel.

Longueur maximale de venlaon

Longueur maximale de venlaon concentrique

1. Déterminez le nombre de coudes à 90 degrés

dans le système de venlaon (Deux coudes à 45

degrés comptent comme un coude à 90 degrés).

2. Reportez-vous à ce tableau pour trouver la

longueur maximale de venlaon compte tenu du

nombre de coudes

3. Réglez SW1 en DIPSW 1 (commutateurs tan) si

requis par la note applicable.

alors passez le SW1 en DIPSW 1 sur ARRÊT.

 Si la longueur est supérieure à 15 pieds (4,6 m),

alors passez le SW1 en DIPSW 1 sur ARRÊT.

 Si la longueur est supérieure à 9 pieds (2,7 m),

alors passez le SW1 en DIPSW 1 sur ARRÊT.

 Passez le SW1 en DIPSW 1 sur ARRÊT.

Exemple : Si vous avez un coude alors la longueur

maximale de venlaon est de 35 pieds

(10,7 m). Si la longueur réelle calculée est

supérieure à 15 pieds (4,6 m), alors passez

le micro-commutateur de SW1 en DIPSW 1

sur ARRÊT.

Si votre longueur de venlaon est plus grande que la

prescripon, alors il faut mere ce SW1 en DIPSW 1

en posion OFF. Cela assure le bon fonconnement
