UNVENTED PROPANE/LP GAS LOG HEATER

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 quali- fied service person. Heater may need more frequent cleaning due to excessive lint from carpeting, pet hair, bedding material, etc.

CLEANING BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE

The primary air inlet holes allow the proper amount of air to mix with the gas. This provides a clean burning flame. Keep these holes clear of dust, dirt, and lint. Clean these air inlet holes prior to each heating season. Blocked air holes will create soot. We rec- ommend that you clean the unit every 2,500 hours of operation or every three months.

We also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recom- mend using compressed air no greater than 30 PSI. Your local computer store, hard- ware store, or home center may carry com- pressed 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 direc- tions on the can. If you don't follow direc- tions 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 holes on injector holder for dust and dirt (see Figure 23).

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 hairs with a soft cloth or vacuum cleaner nozzle.

5.Blow air into the primary air holes 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 assembly. There is a small pilot air inlet hole about two inches from where the pilot flame comes out of the pilot assembly (see Figure 24). With the unit off, lightly blow air through the air inlet hole. You may blow through a drinking straw if compressed air is not available.

LOGS

If you remove logs for cleaning, refer to Installing Logs, page 14, to properly re- place logs.

Replace log(s) if broken or chipped (dime-sized or larger).

MAIN BURNER

Periodically inspect all burner flame holes with the heater running. All slotted burner flame holes should be open with yellow flame present. All round burner flame holes should be open with a small blue flame present. Some burner flame holes may be- come blocked by debris or rust, with no flame present. If so, turn off heater and let cool. Either remove blockage or replace burner. Blocked burner flame holes will create soot.

SERVICE HINTS

When Gas Pressure Is Too Low

pilot will not stay lit

burners will have delayed ignition

heater will not produce specified heat

propane/LP gas supply may be low

When Gas Quality Is Bad

pilot will not stay lit

burners will produce flames and soot

heater will backfire when lit

You may feel your gas pressure is too low or gas quality is bad. If so, contact your local propane/LP gas supplier.
