CLEANING AND

MAINTENANCE

WARNING: Turn off heater

and let cool before cleaning.

CAUTION: You must keep

control areas, burner and circu-

lating air passageways of heater

clean. Inspect these areas of

heater before each use. Have

heater inspected yearly by a qual-

iﬁed service person. Heater may

need more frequent cleaning due

to excessive lint from carpeting,

pet hair, bedding material, etc.

WARNING: Failure to keep

the primary air openings of the

burner clean may result in soot-

ing and property damage.

BURNER INJECTOR HOLDER AND
PILOT AIR INLET HOLE

The primary air inlet openings allow the proper

amount of air to mix with the gas. This provides a

clean burning ﬂame. Keep these holes clear of dust,

dirt, lint and pet hair. Clean these air inlet openings

prior to each heating season. Blocked air openings will

create soot. We recommend that you clean the unit

every three months during operation and have heater

inspected yearly by a qualiﬁed service person.
We also recommend that you keep the burner

tube and pilot assembly clean and free of dust and

dirt. To clean these parts we recommend using

compressed air no greater than 30 PSI. Your local

computer store, hardware store or home center

may carry compressed air in a can. You can use a

vacuum cleaner in the blow position. If using com-

pressed air in a can, please follow the directions on

the can. If you don't follow directions on the can,

you could damage the pilot assembly.
1. Shut off the unit, including the pilot. Allow

the unit to cool for at least thirty minutes.

2. Inspect burner, pilot and primary air inlet

opening on injector holder for dust and dirt

(see Figure 28).

3. Blow air through the ports/slots and holes in

the burner.

4. Check the injector holder located at the end

of the burner tube again. Remove any large

particles of dust, dirt, lint or pet hair with a

soft cloth or vacuum cleaner nozzle.

5. Blow air into the primary air opening on the

injector holder.

6. In case any large clumps of dust have now been

pushed into the burner repeat steps 3 and 4.

Clean the pilot assembly also. A yellow tip on the

pilot ﬂame indicates dust and dirt in the pilot as-

sembly. There is a small pilot air inlet hole about

two inches from where the pilot ﬂame comes out

of the pilot assembly (see Figure 29). With the unit

off, lightly blow air through the air inlet hole in the

same direction as gas ﬂow. You may blow through a

drinking straw if compressed air is not available.
