2.6 Inlet Air and Exhaust Venting Considerations
Applicable Codes and Standards
United States Installation Codes:
Canada Installation Codes:
Flue Gas Exhaust Vent Standards:
These codes and standards contain information for the venting of
gas fired appliances, including, but not limited to vent sizing,
location, clearance to combustibles, and safe installation practices.
The installation must comply with both the above Federal Codes
and with state, provincial, and local codes.
Combustion Air Inlet Planning (United States and
Canada Considerations)
•
Air inlet requirements for the U.S. are established by NFPA
54/ANSI Z223.1 & NFPA/ANSI 211.
•
Air inlet requirements for Canada are established by
CAN/CSA B149.1.
Refer to see section
, for more details on combustion air inlet
requirements in the United States and Canada.
Design and installation of
venting systems should be
done only by qualified and
knowledgeable venting systems
personnel and in accordance
with vent system
manufacturer’s installation
instructions. Installing a boiler
or vent system using improper
installation methods or
materials can result in serious
injury or death due to fire or
asphyxiation.
Before connecting a boiler to a
venting system, it must be
determined whether the boiler
is to be installed in a
conventional or direct vent
configuration. In the US,
provisions for combustion air
must be in accordance with
NFPA 54/ANSI Z223.1, National
Fuel Gas Code, latest edition, or
applicable provisions of local
building codes. In Canada,
combustion and ventilation air
openings shall comply with
CAN/CSA B-149.1 Natural Gas
and Propane Installation Code.
For correct installation of a vent
system, read all of these
instructions and refer to the
vent manufacturer
’s
instructions.
Failure to use a proper vent
system (types and materials), as
described in this manual will
void the boiler warranty and
may result in rapid deterioration
of the venting system, creating
a health or life safety hazard.
Faulty vent installation can
allow toxic fumes to be released
into living areas. This may
cause property damage, injury,
or death.
