INSPECTING BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT ASSEMBLY

The pilot assembly is factory preset for the proper flame height. Alterations may have occurred during shipping and handling. The pilot is located on the back right hand side of the burner.

The thermocouple should be fully enveloped in the flame. The flame should not be lifting off of the thermocouple element.

If your pilot assembly does not meet these requirements:

•Turn the adjustment screw marked pilot clockwise to decrease or counterclockwise to increase the flame to proper size (see Figure 20). Do not remove the adjustment screw.

•see Troubleshooting, pages 13 through 15

BURNER FLAME PATTERN

Burner flames will be steady; not lifting or floating. Flames should go up through the middle of logset. Flames should not "spill" to the edges of the pan or sides of the logset.

Figure 21 shows a typical flame pattern. If burner flame pattern differs from that described:

•turn appliance off (see To Turn Off Gas to Appliance, page 11)

•see Troubleshooting, pages 13 through 15

CLEANING AND

MAINTENANCE

•Keep the area around the log set clean and clear of debris.

•Occasionally, you may use a soft bristle brush to clean logs.

•Periodically inspect the air mixer and burner tube for foreign matter blocking the air inlet and flame holes.

•Once every year a qualified agency or certified chimney sweep should examine and clean the venting system of the fireplace.
