&IGURE
Vent and air piping materials — Use only the materials listed below, ensuring that all materials meet
local codes (
see Figure 125, page 137 for part/kit numbers)
ALL
vent and air pipes require a
BIRD SCREEN at each termination
. Most kits do not include
the bird screens. Purchase bird screens separately from Weil-McLain or vent kit supplier if
not included. [Note — bird screening is integral to the 3" PVC Weil-McLain sidewall vent
cap, available for purchase from Weil-McLain. No additional screening is required.]
USE SWEEP ELBOWS FOR ALL VENT AND AIR PIPING
— DO NOT use short radius
elbows for vent or air piping. Boiler performance could be aff ected.

Note 1:
Weil-McLain concentric vent kits are made from PVC
pipe and fi ttings.
Note 2:
System 636 PVC concentric terminations utilize PVC
pipe/fi ttings certifi ed to ULC S636.
If ULC S636 compliance is required, use only System 636
pipe, fi ttings and cement.
DO NOT mix piping from diff erent pipe manufacturers
unless using adapters specifi cally designed for the purpose
by the manufacturer.
Every joint on
polypropylene vent piping
must
include
a locking collar.
DO NOT use cellular core PVC (ASTM F891), cellular core
CPVC, or Radel
®
(polyphenolsulfone) in venting systems.
DO NOT cover non-metallic vent pipe and fi ttings with
thermal insulation.
ADAPTERS — The boiler comes with a 3" 3-in-
1 adapter as standard. This adapter allows the
installation of 3" PVC schedule 40, CPVC schedule
40, PVC-DWV schedule 40, AL29-4C stainless steel
(from Simpson-Duravent only) and Polypropylene
(from Simpson-Duravent & Centrotherm only)
piping without the need for extra adapters.
ADAPTERS – It may require additional adapters at the
terminations if using diff erent venting materials.
(When going from PP to the Weil-McLain side wall
plate, for example).
ADAPTERS - If using 2" piping, where approved for
the application, provide adapters for a 3" pipe
material (mentioned above) connections and at
the terminations, if required.
