Inspecting Burners

Check pilot flame pattern and burner flame pat- terns often.

PILOT FLAME PATTERN

Figure 24 shows a correct pilot flame pattern. Figure 25 shows an incorrect pilot flame pattern. The incor- rect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.

If pilot flame pattern is incorrect, as shown in Figure 25

•turn heater off (see To Turn Off Gas to Ap- pliance), page 18

•see Troubleshooting, page 21

Note: The pilot flame on natural gas units will have a slight curve, but flame should be blue and have no yellow or orange color.

BURNER PRIMARY AIR HOLES

Air is drawn into the burner through the holes in the fitting at the entrance to the burner. These holes may become blocked with dust, lint or pet hair. Periodi- cally inspect these holes for any blockage and clean as necessary. Blocked air holes will create soot.

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 become blocked by debris or rust, with no flame present. If so, turn off heater and let cool. Remove blockage. Blocked burner flame holes will create soot.

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

WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property damage.

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, lint and pet hair. Clean these air inlet holes prior to each heating season. Blocked air holes 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.
