ORIZONTAL NIT ILTER
Filters in horizontal installations are located in the central return
register or the ductwork near the furnace.
To remove:
1. Turn OFF electrical power to furnace.
2. Remove filter(s) from the central return register or ductwork.
3. Replace filter(s) by reversing the procedure for removal.
4. Turn ON electrical power to furnace.

Follow the manufacturer's directions for service.

URNERS
Visually inspect the burner flames periodically during the heating
season. Turn on the furnace at the thermostat and allow several
minutes for flames to stabilize, since any dislodged dust will alter
the flames normal appearance. Flames should be stable, quiet,
soft, and blue (dust may cause orange tips but they must not be
yellow). They should extend directly outward from the burners
without curling, floating, or lifting off. Flames must not impinge
on the sides of the heat exchanger firing tubes.
I D C
NDUCED RAFT AND IRCULATOR
The bearings in the induced draft blower and circulator blower motors are permanently lubricated by the manufacturer. No further
lubrication is required. Check motor windings for accumulation of dust which may cause overheating. Clean as necessary.
C T D
ONDENSATE RAP AND RAIN
Annually inspect the drain tubes, drain trap, and field-supplied drain line for proper
condensate drainage. Check drain system for hose connection tightness, blockage, and
leaks. Clean or repair as necessary.
F S (Q
LAME ENSOR UALIFIED
Under some conditions, the fuel or air supply can create a nearly invisible coating on the
flame sensor. This coating acts as an insulator causing a drop in the flame sense signal.
If the flame sense signal drops too low the furnace will not sense flame and will lock out.
The flame sensor should be carefully cleaned by a qualified servicer using emery cloth or
steel wool. Following cleaning, the flame sense signal should be as indicated in the
Specifications Sheet.
