INSPECTING BURNERS

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 11)

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.

If burner flame pattern is incorrect, as shown in Figure 18.

turn appliance off (see To Turn Off Gas to Ap- pliance, page 10)

CLEANING AND CAUTION: You must keep control areas, burners and cir- culating air passageways of fire- place clean. Inspect these areas offireplacebeforeeachuse.Have fireplace and chimney (if appli- cable)inspectedyearlybyaquali- fiedserviceperson.Fireplacemay need more frequent cleaning due to excessive lint from carpeting, bedding material, etc.

Only limited cleaning will be required under nor- mal use of this appliance. Dust the front grate and top of receiver/valve. Do not use cleaning fluids to clean logs or any other part of the appliance.

If, after a period of use, the flames start to exhibit unusual shapes and behavior or the burner fails to ignite smoothly, then the burner holes may require some cleaning. If this happens, we recommend that you contact your nearest authorized service technician to get the appliance serviced.

Keep area around log set clean and clear of debris.

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.
