professional training, conduct, and strict
adherence to applicable jurisdictional/
professional codes and regulations.

CAUTION
Do not use insulation on polypropylene
materials. Use of insulation may elevate pipe
wall temperatures, resulting in the potential
for vent material failure.
Ensure there is not negative pressure in the
boiler room. The boiler room pressure must
be neutral relative to the outdoors.

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.
6. The net free area required for the boiler(s) is in addition to the combustion
or ventilation air supply requirements of other equipment sharing the
same space such as water heaters, generators, air compressors, or other
boilers. The boiler room must have an opening or openings not less than
the total net free area required for all types of equipment.
7. Consider the blocking effects of louvers, grills, and screens on the net free
area of each opening. Ensure ventilation openings are unobstructed.
8. Ensure there is not negative pressure in the boiler room. The boiler room
pressure must be neutral relative to the outdoors.
9. Where mechanical combustion air supply systems are used, such as a
combustion air supply fan or a motorized louver, they must be interlocked
with the boiler control panel to prove operation prior to burner ignition
and during burner operation. Where manual louvers are used, ensure they
are fully open prior to operating the boiler(s).
ƒ Air Piped From Outside Boiler Room
The combustion air supply can be piped directly to the air inlet of the boiler.
Adhere to the following for installation:
1. An adapter kit (factory option) is required to connect the boiler air inlet to
the combustion air piping. Use a rubber coupling to connect the air inlet
adapter to the air intake piping.
– NOTEE: The weight of combustion air intake piping must not be supported by the
boiler. Ensure air intake piping is externally supported on hangers or straps.
2. The air intake must be piped out of the building if the boiler room contains
contaminated air.
3. The combustion air intake termination must be located as to not be
subjected to the intake/exhaust of other mechanical equipment such as
other fuel fired heating equipment, loading docks, generators, air handling
systems, and cooling towers.
