Approved Venting Materials; Vent Termination - ECR International Dunkirk DCBF-75 Manual

!
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
• 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.
!
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
Asphyxiation hazard! 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. 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.

5.4 Approved Venting Materials

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.
• Canada - Natural Gas and Propane Installation Code,
CAN/CSA B149.1
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.

5.5 Vent Termination

• Terminate combustion air and vent pipes with fittings
or coaxial vent kit. Refer to venting illustrations for
details.
• 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.
