Combustion Air Supply (continued)
If boiler is installed in a confined space
(a space with a volume of less than 50
cubic feet per 1000 Btu/h of gas input
for all fuel burning equipment) or
building construction is unusually t ight,
adequate air for combustion must be
provided by two openings: one located
about 6” below the ceiling, the other
about 6” above the floor. When
communicating directly with the
outside, each opening must have a
minimum free area of one square inch
per 2000 Btu/h of gas input. When all
combustion air is provided by openings
in doors, etc. to adjoining spaces having
adequate infiltration, each opening must
have a minimum free area of one square
inch per 1000 Btu/h of gas input, but
not less than 100 square inches. See
table below.

used to cover up the combustion and
ventilation openings in closet
installations. If you do not know the
free area, assume 20% for wood
louvers and 60-75% free area for metal
louvers. When using louvers, the
openings have to be made larger. For
example, a f ree 10” x 10” opening
becomes a 14” x 10” opening for a grill
containing metal louvers.

Do not store chemicals containing
chlorine or other corrosiv e chemicals
near the boiler, such as bleach,
cleaning s olvents, detergents, acids,
hair spray, spray cans, paint thinners,
paint, water softener salt,
perchloroethylene, or carbon tetra
chloride.
CAUTION
Exposure to corrosive materials can
cause heat exchanger corrosion and
failure.
CAUTION
Do not locate boiler in areas with high
dust and/or humidity levels.
CAUTION
Do not install boiler during
construction involving drywall or
heavy dust of any kind. D us t can
accumulate in the burners and cause
sooting. Install boiler after all heavy
dust construction is completed.
CAUTION
If the boiler has been exposed to high
dust levels, then all burners and the
heat exchanger must be cleaned prior
to use.
CAUTION
If above criteria are not properly
observed and boiler damage results,
any warranty on the complete boiler
and related components will be null
and void.
