Instructions below - are for the WM 3” and 4” PVC

Concentric Kit. If using Simpson-Duravent or Centrotherm

Concentric kit, please refer to the manufacturer’s installation

instructions.

Allowablevent/airpipematerials&lengths

1. e concentric termination kit must be purchased separately.

Use only the vent materials and kits listed in Fig-

ure24,page21. Provide pipe adapters if specied.

2. Locate the termination such that the total air pip-

ing and vent piping from the boiler to the termina-

tion will not exceed the maximum length given in

Figure23,page20.

is termination requires a 45-degree elbow that is not sup-

plied with the termination kit. e maximum vent/air pipe

len

gths include allowance for this elbow.

For polypropylene applications, comply with

any additional requirements in the vent system

manufacturer’s instructions. Provide 4” PVC-to-

PP transition pieces at the boiler vent and air con-

nections. PP adapter must have smooth, straight

section of pipe to insert in to the boiler vent and

air connections and must t and seal tightly. PP

adapters with their own seal which would inter-

fere with the internal seal of the boiler vent or air

connections must not be used. Refer to page117

for a list of compliant adapters. Install a locking

collar at every joint.

For AL29-4C vent pipe applications, comply with

any additional requirements in the vent system

manufacturer’s instructions. Provide a 4”PVC

transition at the boiler vent connection. Air pipe

must be PVC or CPVC. Provide transition pieces

to PVC at the vent and air pipe termination con-

nections.

4. For 4” to 3” transitions, must use appropriate vent material.

For polypropylene or stainless steel must use approved sup-

pliers transitions (EVG 220 only).

Determineterminationlocation

1. Wall penetration thickness between 0” to 24”.

2. e concentric termination kit must be installed as shown

in Figure36,page30.

3. e termination must comply with clearances and limita-

tions shown in Figure25,page23.

4. Locate the termination so it is not likely to be damaged

by foreign objects, such as stones or balls, or subject to

buildup of leaves or sediment.

Multiplevent/airterminations

1. When terminating multiple Evergreen

boilers, install each

concentric termination as described in this manual.

All vent pipes and air inlets must terminate at the same

height to avoid possibility of severe personal injury,

death or substantial property damage.

2. Place wall penetrations to obtain minimum clearance as

shown in Figure36,page30 for U. S. installations. For Ca-

nadian installations, provide clearances required by Natural

s and Propane Installation Code,

CAN/CSA B149.1 or

B149.2 Installation Code and a ULCS636 compliant vent kit.

3. e air inlet of a Evergreen

boiler is part of a direct vent

connection. It is not classied as a forced air intake with

regard to spacing from adjacent boiler vents.

Step1 Read and follow all instructions in this manual. DONOT

proceed with vent/air installation until you have

readpage19throughpage24.

See

notices at le.

Step2 Install the boiler in a location that allows proper routing of all

vent and air piping to the selected sidewall location.

Step3 Make sure the selected sidewall termination location complies

with Figure25,page23. (Multiple boiler concentric termina-

tions must also comply with Figure35,page30.)

Step4 Use only the vent materials listed in Figure24,page21. Pro-

vide pipe adapters where required.

Step5 Vent piping and air piping lengths must not exceed the values

shown in Figure23,page20.

Step6 Ensure proper clearance above grade or snowline. Keep vents/

air intake area clear of accumulating snow.

Step7 e concentric termination must be assembled and installed

before piping from the boiler to the termination.

Step8 Prepare the sidewall penetration — assemble the concentric

termination kit and secure the cover plates as instructed in

this section. Provide the supports indicated and mount the

termination assembly. See “Install termination — concentric

pipes” on page30.

See notices at le.

Step9 Install vent and air piping between the boiler and the concen-

tric vent/air termination. Slope horizontal piping downward

toward the boiler at least 1/4 inch per foot. See page38 for

general guidelines.

Step10 Install pipe supports every 5 feet on both the horizontal and

vertical runs.

See notices at le.

Step11 Install a hanger support within 6inches of any upturn in the

piping.

See notices at le.

AIRPIPING — DO NOT use short radius elbows

for vent or air piping. Boiler performance could be

aected.
