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.
