PREPARING FOR INSTALLATION

Ventilation Air From Inside Building

This fresh air would come from adjoining unconfined space. When ventilating to an adjoining unconfined space, you must provide two permanent openings: one within 12 in. of the wall connecting the two spaces (see options 1 and 2, Fig. 1). You can also remove door into adjoining room (see option 3, Fig. 1). Follow the National Fuel Gas Code NFPA 54/ANS Z223.1. Air for Combustion and Ventilation for required size of ventilation grills or ducts.

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or duct. You must provide two permanent openings: one within 12 in. of the ceiling and one within 12 in. of the floor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. Follow the National Fuel Gas Code NFPA 54/ANS Z223.1. Air for Combustion and Ventilation for required size of ventilation grills or ducts.

IMPORTANT: Do not provide openings for inlet or outlet air into attic if attic has a thermostat-controlled power vent. Heated air entering the attic will activate the power vent. Rework worksheet, adding the space of the adjoining unconfined space. The combined spaces must have enough fresh air to supply all appliances in both spaces.

Mounting Bracket

The mounting bracket is located separately from the unit, but packed inside the same box.

Methods For Attaching Mounting Bracket To Wall

Use only the last hole on each end of mounting bracket to attach bracket to wall. Attach mounting bracket to a wall only in one of two ways:

1. Attaching to wall stud: This method provides the strongest hold. Insert wood screws (ST.8*45-16) through mounting bracket and into wall studs.
2. Attaching to expansion bracket: This method allows you to attach mounting bracket to hollow walls (wall areas between studs) or to solid walls (concrete or masonry).

Decide which method better suits your needs. Either method will provide a secure hold for the mounting bracket.

Marking Screw Locations

1. Tape mounting bracket to wall where heater will be located. Make sure mounting bracket is level.
2. Mark screw locations on wall (See Fig. 16).
   Note: Mark only last hole on each end of mounting bracket. Insert (2) wood screws (ST.8*45-16) total through these holes only.
3. Remove tape and mounting bracket from wall.

Attaching Mounting Bracket To Wall

Note: Expansion bracket, wood screws (ST.8*45-16), and wall hanging spacers are in hardware package. The hardware package is provided with heater.

Attaching to Wall Stud Method

For attaching mounting bracket to wall studs:

1. Drill holes at marked locations using 9/64-inch drill bit.
2. Place mounting bracket onto wall. Line up last hole on each end of bracket with holes drilled in wall.
3. Insert wood screws (ST.8*45-16) through bracket and into wall studs.
4. Tighten wood screws (ST.8*45-16) until mounting bracket is firmly fastened to wall studs.
5. Check that the bracket is secure before mounting heater!

Attaching to Expansion Bracket Method For attaching mounting bracket to hollow walls (wall areas between studs) or solid walls (concrete or masonry):

1. Drill holes at marked locations using 5/16-inch drill bit. For solid walls (concrete or masonry), drill at least 1 inch deep.
2. Fold wall expansion bracket as shown in (See Fig. 17).
3. Insert wall expansion bracket (wings first) into hole. Tap expansion bracket flush to wall.
4. For thin walls (1/2 inch or less), insert expansion bracket tool into expansion bracket. Push expansion bracket tool to “pop” open expansion bracket wings (See Fig. 18).
   
   IMPORTANT: Do not hammer expansion bracket tool! For thick walls (over 1/2 inch thick) or solid walls, do not pop open wings.
5. Place mounting bracket onto wall. Line up last hole on each end of bracket with expansion bracket.
6. Insert expansion bracket screws (ST4.8*15-16) through wall mounting bracket and into expansion brackets.
7. Tighten expansion bracket screws (ST4.8*15-16) until mounting bracket is firmly fastened to wall.
8. Check that the bracket is secure before mounting heater!

Attaching Wall Hanging Spacers to Heater

WARNING: Failure to properly install the wall hanging spacers may result in property damage, personal injury or even death.

1. Locate spacer mounting holes on the lower right/left sections of the heater back panel.
2. Secure (2) wall hanging spacers to heater back panel using (2) wall hanging spacer screws (M4*25) (See Fig. 19a).

Placing Heater On Mounting Bracket

1. Locate two horizontal slots on back panel of heater.
2. Place heater onto mounting bracket. Slide horizontal slots onto stand-out tabs on mounting bracket. Be sure spacers rest evenly against wall (See Fig. 19b).

CONNECTING TO GAS SUPPLY

WARNING: A qualified service technician must connect heater to gas supply. Follow all local codes.

IMPORTANT: This appliance requires a 3/8-inch NPT (National Pipe Thread) inlet connection to the pressure regulator. Never connect the heater to private (non-utility) gas wells, commonly known as wellhead gas.

WARNING: Do not overtighten gas connections.

CAUTION: Use only new, black iron or steel pipe. Internally tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2-in. diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.

CAUTION: Check your gas line pressure before connecting heater to gas line. Gas line pressure must be a minimum 6'' WC for NG & 11" WC for LP with a max pressure of 9'' WC for NG & 14" WC for LP. If gas line pressure is higher, the unit will not work and heater regulator damage could occur.

CAUTION: Never connect heater directly to an LP supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and gas supply.

CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting into gas piping and/or fittings.

CAUTION: Use pipe joint sealant that is resistant to gas (Propane or Natural Gas).

Typical Inlet Pipe Diameters

Use 3/8-inch black iron pipe or greater. Installation must include an equipment shutoff valve, union, and plugged 1/8-inch NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Fig. 20).

IMPORTANT: Install an equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on or shutting off the gas to the appliance.

Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves.

Install sediment trap in supply line as shown (See Fig. 20). Place sediment trap where it is within reach for cleaning. Place sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into heater controls. If sediment trap is not installed or is installed wrong, heater may not run properly

CHECKING GAS CONNECTIONS

WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct all leaks immediately.

WARNING: Never use an open flame to check for a leak. Apply a 50/50 mixture of liquid soap and water to all joints. If bubbles form, there may be a leak. Correct all leaks immediately.

Pressure Testing Gas Supply Piping System Test Pressures In Excess Of 1/2 PSIG ( 3.5kPa )

The appliance and its appliance main gas valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of ½ psi (3.5 kPa).

Pressure Testing Gas Supply Equal To or less than 1/2 PSIG ( 3.5kPa )

The appliance must be isolated from the gas supply piping system by closing its equipment shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than ½ psi (3.5 kPa).

Leak Testing Heater Gas Internal Connections

1. Open equipment shutoff valve (See Fig. 21).
2. Make sure control knob of heater is in the OFF position.
3. Open gas supply tank valve (LP systems).
4. Check all joints from equipment shutoff valve to control valve. Apply 50/50 mixture of liquid soap and water to gas joints. If bubbles form, there may be a leak.
5. Light heater (see Operation, page 18). Check all other internal joints for leaks.
6. Turn off heater (see "To Turn Off Gas to Appliance," page 19).
