Inspection and Maintenance
Procedures
It is a good practice to make a periodic inspection of
the boiler. It is recommended that the home owner or
user check the boiler after the first and third month of
operation, and then on an annual basis, or more often
if desired. It is also recommended to have a qualified
service agency check the boiler before each heating
season, or at anytime there may be an indication of a
problem.
Burner Inspection
Clean the main burners and air louvers of dust, lint and
debris. With burner in operation, make a visual check
of the burner flame and the pilot flame (when
equipped). Yellow flames indicate some restriction of
combustion air openings. A bright orange, luminous
flame is not normal and can cause sooting under pro-
longed operation. Should this condition be observed,
immediately contact a qualified service agency to cor-
rect the problem.

CAUTION: Should overheating occur or the gas
supply fail to shut off, DO NOT turn off or disconnect
the electrical supply to the pump. Instead, shut off
the gas supply at a location external to the
appliance. Failure to observe this precaution may
aggravate the overheated condition resulting in
possible damage to the boiler and injury to the user.
DANGER: Keep boiler area clear and free from
combustibles and flammable materials. Do not
obstruct the flow of combustion and ventilating air
into the boiler enclosure. Failure to observe these
safety precautions can cause fire, explosion, or
asphyxiation.
