Combustion air piping - if used - is inserted directly into the 3” female stainless steel tting
on the top, right side of the boiler and run horizontally or vertically to the outdoors. Screen
material can be placed at the inlet as appropriate for the environment (e.g. insects, dust).
Care must be taken to ensure adequate separation is maintained between the air intake
inlet and the vent terminal. Refer to the vent terminal conguration drawings in the Vent
Termination section above.
Support should be provided for intake piping, particularly so for horizontal runs (follow
local code).
1.4.8 “Indoor Air” Combustion Air Intake
An “Indoor Combustion Air installation”, as described herein, is one in which air for
combustion is taken from the ambient air around the boiler.
To support combustion, an ample air supply is required. This may require direct openings
in the boiler room to the outside. If the boiler is not in a room adjacent to an outside wall, air
may be ducted from outside wall openings.
Provisions for combustion and ventilation air must be made as follows:
• in the USA, in accordance with the National Fuel Gas Code, ANSI Z223.1 (latest
edition), or applicable provisions of the local building codes
• in Canada, in compliance with B149.1-10
WARNING
When using Indoor Air options,
adequate combustion air must
be supplied to the boiler room
according to the requirements of
all applicable codes.
