ate better, more efficiently and more economically.
2. Arrange the furniture and drapes so that the supply air
registers and the return air grilles are unobstructed.
3. Close doors and windows. This will reduce the heating
load on the system.
4. Avoid excessive use of kitchen exhaust fans.
5. Do not permit the heat generated by television, lamps
• The furnace should operate for many years without ex-
cessive scale build-up in the flue passageways. How-
ever, it is recommended that a qualified installer, service
agency, or the gas supplier annually inspect the flue pas-
sageways, the vent system and the main burners for con-
tinued safe operation. Pay particular attention to
deterioration from corrosion or other sources.
• IMPORTANT: It is recommended that at the beginning
and at approximately half way through the heating sea-
son, a visual inspection be made of the main burner
flames for the desired flame appearance by a qualified
installer, service agency or the gas supplier. If the flames
are distorted and/or there is evidence of back pressure,
check the vent and inlet air system for blockage. If there
is carbon and scale in the heat exchanger tubes, the heat
exchanger assembly should be replaced.

fine steel wool or Scotch Bright Pad by a qualified in-
staller, service agency or the gas supplier.
• IMPORTANT: It is recommended that at the beginning of
the heating season, the condensate trap be inspected for
debris or blockage. A blocked condensate trap can cause
water to back up into the primary heat exchanger and
lead to nuisance tripping of the overtemperature
switches.
• IMPORTANT: It is recommended that at the beginning of
the heating season, the condensate neutralizer if used be
replaced by a qualified installer, service agency or the
gas supplier.
• IMPORTANT: It is recommended that an annual inspec-
tion and cleaning of all furnace markings be made to as-
sure legibility. Attach a replacement marking, which can
be obtained through the distributor, if any are found to be
illegible or missing.
• IMPORTANT: It is recommended that at the beginning of
each heating season the flue couplings and hoses be
checked for damage or water leakage. Hose couplings
and clamps should be tight and free of cracks. Tighten
and replace damaged components as necessary.
