IV. Venting
B. CPVC/PVC Venting - C. Polypropylene Venting (continued)
- Install storm collar on vent pipe
immediately above flashing. Apply
Dow Corning Silastic 732 RTV
Sealant or equivalent between vent
pipe and storm collar to provide
weather-tight seal.
• Install rodent screen and vent terminal
(supplied with boiler). See Figure 13 for
appropriate configuration.
• Brace exterior piping if required.
ii.
Combustion Air Piping
• If possible, locate combustion air
termination on the same roof location as
the vent termination to prevent nuisance
boiler shutdowns. Combustion air terminal
may be installed closer to roof than vent.
Alternatively, boiler may be installed with
vertical roof vent terminal and sidewall
combustion air terminal.
• Size roof opening to allow easy insertion
of combustion air piping and allow proper
installation of flashing and storm collar
to prevent moisture from entering the
structure.
- Use appropriately designed
vent flashing when passing through
roofs. Follow flashing manufacturers’
instructions for installation
procedures.
- Extend combustion air pipe to
maintain minimum vertical
and horizontal distance of 12 in.
(300 mm) from roof surface. Allow
additional vertical distance for
expected snow accumulation. Provide
brace as required.
- Install storm collar on combustion air
pipe immediately above
flashing. Apply Dow Corning Silastic
732 RTV Sealant or equivalent
between combustion air pipe and
storm collar to provide weather-tight
seal.
• Install rodent screen and combustion air
terminal (supplied with boiler). See Figure
13 for appropriate configuration.
• Brace exterior piping if required.
C. Polypropylene Venting
WARNING
Asphyxiation Hazard. Follow these
instructions and the installation instructions
included by the original polypropylene
venting component manufacturers, M&G/
DuraVent or Centrotherm, whichever
applicable. Failure to do so could cause
products of combustion to enter the
building, resulting in severe property
damage, personal injury or death.
Where a conflict arises between M&G/
DuraVent or Centrotherm instructions and
these instructions, the more restrictive
instructions shall govern.
Do not mix vent components or joining
methods for listed manufacturers.
Examine all components for possible
shipping damage prior to installation.
All condensate that forms in the vent must
be able to drain back to the boiler.

1. Components
a. Listed polypropylene vent system manufacturers
are shown in Table 9. It is the responsibility of
the installing contractor to procure polypropylene
vent system pipe and related components.
i.
M&G/DuraVent PolyPro Single Wall Rigid
Vent and PolyPro Flex Flexible Vent comply
with the requirements of ULC-S636-08
‘Standard for Type BH Gas Venting
Systems’.
NOTICE
Do not exceed maximum vent/combustion air
system length. Refer to “2. Vent/Combustion
Air Piping” under “A. General Guidelines” of
this section for maximum vent/combustion air
system length.
Use only vent and combustion air terminals
and terminal locations shown in “3. Vent/
Combustion Air Terminals” under “A.
General Guidelines” of this section.
