IV. Venting
B. CPVC/PVC Venting - C. Polypropylene Venting (continued)
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.
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.
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.
