Flue Passages (Qualified Servicer Only)

At the start of each heating season, inspect and, if neces-

sary, clean the unit flue passage.

Cleaning Flue Passages (Qualified Servicer Only)

1. 

Shut off electric power and gas supply to the unit. 

2.  Remove burner assembly by disconnecting the gas 

line and removing the manifold bracket from the par-

tition panel.

3. 

Remove the flue from the induced draft blower and the 

collector box cover 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 ca-

ble. 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 op-

eration with a small cable for the smaller tube. Repeat 

for each tube.

5.  When all heat exchanger tubes have been cleaned, re-

place 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, Adjust-

ments, and Checks”.

Main Burner Flame (Qualified Servicer Only)

Flames should be stable, soft and blue (dust may cause or

-

ange tips but must not be yellow). The flames must extend 

directly outward from the burner without curling, floating or 

lifting off.

At least once a year, prior to or during the heating season, 

make a visual check of the burner flames. 

NOTE: 

This will involve removing and reinstalling the heat 

exchanger door on the unit, which is held by two screws. 

If you are uncertain about your ability to do this, contact a 

qualified servicer.

If a strong wind is blowing, it may alter the airflow pattern 

within the unit enough that an inspection of the burner 

flames is not possible.

Check the

Burner Flames for:

1. Stable, soft and blue.

2. Not curling, floating

    or lifting off.

Cleaning Burners

1. 

Shut off electric power and gas supply to the unit.

2.  Remove the screws securing the manifold to the burn-

er retention bracket. Remove the manifold and rotate 

each burner counterclockwise to remove.

3.  Remove the burners.

4.  Use a bottle brush to clean burner insert and inside of 

the burners.

5.  Replace burners and manifold, inspect the burner as-

sembly for proper seating of burners in retention slots.

6.  Reconnect electrical power and gas supply.

For further information on the yearly inspection, consult the 

User  Manual.  It  is  recommended  that  a  qualified  servicer 

inspect and service the unit at least once each year.

Turn the unit on at the thermostat. Wait a few minutes, since 

any dislodged dust will alter the normal flame appearance. 

Flames should be predominantly blue and directed into the 

tubes. They should not be yellow. They should extend direct-

ly outward from the burner ports without curling downward, 

floating or lifting off the ports.
