3.4.2 Combustion Air and Venting
Requirements for Canada
Canadian Standard CAN/CSA-B149.1-05,
Natural gas and propane installation code
specifies venting systems and air supply for
appliances in Section 8. Paragraph 8.1.4 states
"Air supply shall be provided in accordance
with Clause 8.4 when either an appliance or a
combination of appliances has a total input
exceeding 400,000 Btuh. Air supply is defined
as combustion air, excess air, flue gas dilution
air, primary air, secondary air, and ventilation
air. The air supply requirements below are a
summation of Clause 8.4 specific to this
boiler.
3.4.2.1 Air Supply Requirements per
CAN/CSA-B149.1-05 for
Appliances having an input
exceeding 400 MBH.
Ventilation Air: an opening for ventilation air
at the highest point that opens to the
outdoors shall provide Ventilation of the
space. The cross sectional area of this
opening shall be at least 10% of the area
required for combustion air, but in no case
shall the cross-sectional area be less that 10 in
2
(6500mm
).
Combustion Air: For combustion air where
the air supply is provided by natural airflow
from outdoors, in addition to the opening for
ventilation air, there shall be permanent
opening having a total cross-sectional free
area of not less than 1 in
BTU/hr. (70 mm
2
for each kW) of the total
rated input of the boiler(s). The location of
the opening(s) shall not interfere with the
openings for ventilation air. Please refer to
CAN/CSA-B149.1-05, Para. 8.4.4, for
combustion air openings if there are natural
draft, fan assisted or power draft assisted
equipment in the space.
When an air supply duct is used to supply
combustion air, it's discharge opening shall be
