perchlorethylene, halogenated compounds) in the combustion air supply
to the boiler will cause damage or failure to the heat exchanger and/
or burner, and is not covered under warranty. High-risk situations for
particulate matter to be in the air include construction and maintenance
activities. See Table 5.
NOTEE: Pool and laundry room air may be contaminated with chlorine or fluorine
–
compounds. If allowed to enter the combustion air supply, these contaminants
will significantly increase the acidity of flue gas condensate, potentialy damaging
heat transfer surfaces. Damage to the heat exchanger due to poor combustion air
quality is not covered under warranty.

ƒ Combustion Air Supply From the Boiler Room
Adhere to the following for installation:
1. Adequate combustion air and ventilation must be supplied to the boiler
room in accordance with local codes and NFPA54/ANSI Z233.1, Section
9.3, Air for Combustion and Ventilation or CSA-B149.1 for Canada. The
minium net free area requirements in Table 6 may not supersede local and
jurisdictional codes and regulations where there codes and regulations
require an opening of greater net free area. The boiler room must meet the
NFPA criteria for a non-confined space.
2. Verify combustion air is taken from the outdoors and not from the inhabited
or occupied spaces within the building. Ensure space and nearby products
are evaluated for the potential of combustion air contaminants. See Table 5.
3. For installations providing two permanent openings directly
communicating with the outdoors, the minimum net free area of each
opening is 1 in2 per 4,000 BTU/hr of the total input capacity of the
combined burners located in the boiler room. Ensure a high opening
commences within 12 inches of the ceiling, and a low opening commences
within 12 inches of the floor. See Table 6.
4. For installations providing a single permanent opening directly
communicating with the outdoors, the minimum net free area of each
opening is 1 in2 per 3,000 BTU/hr of the total input capacity of the
combined burners located in the boiler room. See Table 6.
5. For multiple boiler installations, multiply the number of boilers by required
net free area per boiler.

CAUTION
Ensure there is not a negative pressure in the
boiler room. The boiler room pressure must
be neutral relative to the outdoors.
Particulate matter or chemicals (exampleE:
chlorine, fluorine, perchlorethylene,
halogenated compounds) in the
combustion air supply to the boiler will
cause damage or failure to the burner.
High-risk situations for particulate matter
to be in the air include construction and
maintenance activities. See Table 5.
