5.4 Approved Venting Materials
5.5 Vent Termination
•
Terminate combustion air and vent pipes with fittings
or coaxial vent kit. Use horizontal pipe for vent and
90° elbow for combustion air termination when using
fittings.
• Separate vent terminal from air inlet terminal to
prevent flue gas recirculation. If T-Terminal is used
on flue pipe at sidewall, air inlet terminal shall be at
least 36" or more away from vent terminal.
• Locate combustion air termination as far as possible
from swimming pool, swimming pool pump house,
and other sources of airborne chlorine.
• Locate combustion air and vent terminals as required
by authority having jurisdiction.
Approved Polypropylene Manufacturers
* Natalini
* DuraVent
®
*Centrotherm
* Z-Flex
®
Note: Maximum equivalent length may vary between
manufacturers.
Installation shall conform to requirements of authority
having jurisdiction or in absence of such requirements:
• USA - National Fuel Gas Code, ANSI Z223.1/NFPA
54.
WARNING
Manufacturer recommends this condensing boiler
be vented with approved polypropylene venting
material. Use only materials listed below for
vent pipe, intake air pipe, and fittings. Failure to
comply could result in death or serious injury.
!
WARNING
Do not use cellular core pipe. Only specified
sized pipes are to be used. When using venting
material other than boiler manufacturer's
venting, note the correct installation procedure.
Failure to follow these instructions could result in
death, or serious injury.
!
WARNING
•
Covering non-metallic vent pipe and fittings
with thermal insulation shall be prohibited.
•
Use of cellular core PVC for venting flue gas
could result in death, or serious injury.
• Coaxial venting shall be fastened with screws.
Dual flue venting is NOT fastened with screws.
!
1.
Venting shall be properly supported.
2.
Boiler shall not support any type of vent system.
3.
All piping, glue, solvents, cleaners, fittings and
components must conform to ASTM and ANSI
standards. In Canada ULC S636 and in the USA UL
1738 schedule 40 CPVC are the only approved vent
system to be used as an alternative to polypropylene
venting for the exhaust pipe.
4.
Manufacturer requires use of a mechanical fastener
at every push-fit gasket connection when using a
single wall polypropylene vent system.
5 - COMBUSTION AIR AND VENT PIPING
WARNING
Pipe outdoor combustion air directly to boiler
air connection. Ensure combustion air does not
contain contaminants and is not drawn from an
area likely to have contaminants per Table 5-2.
For example, never pipe combustion air from
areas near swimming pools or laundry room
exhaust vents. Contaminated combustion air
will damage boiler resulting in death or serious
injury.
!
Install an air filter which allows at least 800 cfm if
the area is subject to dirty or dusty intake air. Boiler
performance at maximum length may be impacted when
an air filter is used.
If interior or exterior construction in vicinity of boiler
is taking place, take precautions to avoid exposing the
boiler to fine particulate dust. If boiler is exposed to
any dust or dirt it must be cleaned and serviced.
