INSPECTING BURNERS

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

PILOT FLAME PATTERN

Figure 45 shows a correct pilot flame pattern. Figure 46 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the ther- mocouple. This will cause the thermocouple to cool. When the thermocouple cools, the fireplace will shut down.

If pilot flame pattern is incorrect, as shown in Figure 46

•turn fireplace off (see To Turn Off Gas to Appli- ance, page 22 for Thermostat-Controlled Mod- els or page 24 for Remote-Ready Models)

•see Troubleshooting, page 29

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 FLAME PATTERN

Figure 47 shows a correct burner flame pattern. Figure 48 shows an incorrect burner flame pattern. The incorrect burner flame pattern shows sporadic, irregular flame tipping. The flame should not be dark or have an orange/reddish tinge.

Note: When using the fireplace the first time, the flame will be orange for approximately one hour until the log cures.

If burner flame pattern is incorrect, as shown in Figure 48

•turn fireplace off (see To Turn Off Gas to Appli- ance, page 22 for Thermostat-Controlled Mod- els or page 24 for Remote-Ready Models)

•see Troubleshooting, page 29

CAUTION: You must keep

control areas, burner and cir-

culating

air passageways of

fireplace

clean. Inspect these

areas of fireplace before each

use. Have fireplace inspected

yearly by a qualified service

person. Fireplace may need

more frequent cleaning due to

excessive lint from carpeting,

pet hair, bedding material, 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 fireplace inspected yearly by a qualified

service person.
