3.21 Combustion Air and Ventilation Openings
Provisions for combustion and ventiiation air must be made in accordance with section 5.3, Air
for Combustion and Ventilation, of the National Flue Gas Code, ANSI Z223.1/NFPA 54., or
Sections 7.2, 7.3 or 7.4 of CAN/CSA-B149.1-05, installation codes, or appilcable provisions of
the local building codes.
3.21.1 Insufficient Ventilation and Combustion Air
BOILER DAMAGE AND OPERATIONAL FAILURES may occur due to insufficient or improper
openings for combustion air and/or ventilation of the boiler room.
Provisions for combustion air and ventilation are always required, regardless of whether the
combustion air is taken from the outside (sealed combustion) or inside (room air used as
combustion air).
Insufficient ventilation of the boiler room can lead to high air temperatures. This can result in boiler
damage. Note the following:
•
Make sure that intake and exhaust openings are sufficiently sized and no
reduction or closure of any openings takes place.
• When a combustion air or ventilation problem is not resolved, do not operate
the boiler.
When one expects contaminated combustion air (near swimming pools, chemical cleaning
operations, hair salons, etc.), sealed combustion operation is recommended.
