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 curl-
ing, floating, or lifting off. Flames must not impinge on the sides of
the heat exchanger firing tubes.

NDUCED RAFT AND IRCULATOR
The bearings in the induced draft blower and circulator blower mo-
tors are permanently lubricated by the manufacturer. No further lu-
brication is required. Check motor windings for accumulation of
dust which may cause overheating. Clean as necessary.

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 nec-
essary.

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 insu-
lator 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 1 to 4 microamps at 115 volts.

LUE ASSAGES UALIFIED
The heat exchanger flue passageways should be inspected at the
beginning of each heating season. If necessary, clean the pas-
sageways as outlined below.
1. Turn OFF the electrical power and gas supply to the furnace.
2. Disconnect the gas line and remove the burner/ manifold
assembly by removing the screws securing the assembly to
the partition panel.
3. Disconnect the flue pipe system from the induced draft blower.
4. Remove the induced draft blower and, drain and pressure
tap hoses from the recuperator coil front cover.
5. Remove the recuperator coil front cover to expose the coil
tubes and turbulators.
6. Remove the recuperator coil turbulators individually by slowly
pulling each turbulator forward firmly.
7. Clean the recuperator coil tubes using a long handle wire
brush, such as a gun cleaning brush.
8. Clean the primary heat exchanger tubes using a wire brush
attached to a length of high grade stainless steel cable, such
as drain cleanout cable. Attach a variable speed reversible
drill to the other end of the cable. Slowly rotate the cable
with the drill and insert it into one of the heat exchanger
tubes. While reversing the drill, work the cable in and out
several times to obtain sufficient cleaning. Repeat for each
tube.
