Furnace Maintenance
Condensate Drainage System Inspection
1. Inspect condensate drain lines to be sure
they are free of debris and free flowing.
2. Inspect all condensate lines for freezing
and verify operation of freeze protection
(heat trace tape). The factory installed
section of the condensate line includes a heat
trace. All field installed condensate lines
must also include heat trace.
3. Inspect and clean out all waterless p-traps
of condensate/ mildew buildup.
4. Inspect and replace the condensate
neutralizer cartridge if necessary.
Furnace Exhaust Vent Termination
1. Inspect all flue exhaust vent
terminations/outlets. Remove any ice
accumulation. Ice accumulation can affect
performance and operation of the furnace.
2. Inspect the roof floor in front and/or below
any flue exhaust termination and furnace
access door. Remove any ice accumulation.
Disconnect all electrical power
sources before servicing the unit.
More than one power source may be
provided. Failure to do so may result
in injury or death from electrical shock
or entanglement in moving parts.
If any original wiring needs to be
replaced it must be replaced with
wiring materials suitable for 105ºC.
Label all wires prior to disconnection
when servicing unit. Wiring errors can
cause improper or dangerous
operation. Verify proper operation
after servicing.
Improper installation, adjustment,
alteration, service or maintenance can
cause property damage, personal
injury or loss of life. Startup and
service must be performed by a
Factory Trained Service Technician. A
copy of this IOM should be kept with
the unit.
