Inspecting Burners, Pilot Flame Pattern

OPERATING APPLIANCE

Continued

NOTICE: You must light the pilot before using the hand-held re- mote control unit. See Lighting Instructions on page 10.

After lighting, let pilot ﬂame burn for about one minute. Turn control knob to ON posi- tion. Adjust ﬂame adjustment knob anywhere between HI and LO. Flip AUTO/OFF/ON switch to AUTO. Slide the selector switch to the REMOTE position (see Figure 13). Note: The burner may light if hand-held remote was on when selector switch was last turned off. You can now turn the burner on and off with the hand-held remote control unit.

IMPORTANT: Do not leave the selector switch in the REMOTE or ON position when the pilot is not lit. This will drain the battery.

INSPECTING BURNERS

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

PILOT FLAME PATTERN

You can view the pilot light through the pilot view- ing hole on the pilot bracket. This is located under the front grate bar on the right side of the log set.

Figure 15 shows a correct pilot ﬂame pattern. Figure 16 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 appliance will shut down.

If pilot ﬂame pattern is incorrect, as shown in Figure 16

•turn appliance off (see To Turn Off Gas to Appliance), page 10

•see Troubleshooting, page 13

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