Maintenance
Burners
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.
Induced Draft and Circulator Blowers
The bearings in the induced draft blower and circulator
blower motors are permanently lubricated by the manufac-
turer. No further lubrication is required. Check motor
windings for accumulation of dust which may cause over-
heating. Clean as necessary.
Qualified Servicer Only
CONDENSATE TRAP AND DRAIN SYSTEM
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.
FLAME SENSOR
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.
IGNITER
If the igniter and the surrounding air are at about 70°F and
the igniter wires are not connected to any other electrical
components, the resistance of the igniter should not
exceed 200 ohms. If it does, the igniter should be replaced.
FLUE PASSAGES
Inspect the heat exchanger flue passageways at the be-
ginning of each heating season. If it is necessary to clean
them, follow the steps outlined below.
1. Turn OFF the electrical power and gas supply to the
furnace.
2. Remove burner assembly by disconnecting the gas
line and removing the manifold brackets from the
partition panel.
3. Remove the flue from the induced draft blower and
the collector box from the partition panel.
4. The primary heat exchanger tubes can be cleaned
using a round 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 spring cable. Slowly rotate the cable
with the drill and insert it into one of the primary heat
exchanger tubes. While reversing the drill, work the
cable in and out several times to obtain sufficient
cleaning. Use a large cable for the large tube, and
then repeat the operation with a small cable for the
smaller tube. Repeat for each tube.
5. When all heat exchanger tubes have been cleaned,
replace the parts in the reverse order in which they
were removed.
6. To reduce the chances of repeated fouling of the
heat exchanger, perform the steps listed in Startup
Adjustments and Measurements.
BURNER CLEANING
1. Shut off electric power and gas supply to the fur-
nace.
2. Remove screws securing manifold to burner bracket.
Slightly pull manifold out and away from burner
bracket. Burners will drop. Re-secure manifold to
burner bracket.
3. Tilt burners to slotted side of burner bracket. Rotate
burners clockwise to remove.
4. Use bottle brush to clean burner insert and inside of
burner.
5. Replace burner (opposite of removal). Ensure burn-
ers are fully seated on burner bracket tabs and are
properly aligned.
6. Turn on electric power and gas supply to the fur-
nace.
7. Check furnace for proper operation. Refer to “Op-
erational Checks” section to verify burner flame char-
acteristics.
