Page 21

MAINTENANCE

Always Turn Off Gas Control Valve Before Cleaning. Annual Maintenance Should Only Be Performed By A Qualified Service Technician:

PERIODIC CHECK OF PILOT AND BURNER FLAMES

Check the operation of the pilot and cycle the burner. Visually check the flame of the burner making sure the flames are steady; not lifting or floating. The flame color should be blue at the burner with yellow body and tops.

Cycle unit a minimum of 2 times

•Watch for smooth burner ignition and shut down.

•Burner: Check flame patterns. Ensure that burner flame appearance does not vary greatly from diagram shown on this page.

•Pilot: Ensure pilot flame appearance does not vary greatly from diagram shown below.

PILOT FLAME APPEARANCE

A proper pilot flame should consist of torch-like flame issuing from the pilot hood as shown in illustration below.

BURNER FLAME APPEARANCE

A periodic visual check of the pilot and burner flames should be performed. If either the pilot or burner flame do not show proper appearance or behavior, as outlined here, consult a qualified gas appliance technician.

Proper Pilot Appearance

A proper burner flame is shown above. The burner flame should have the following characteristics after initial start-up (let appliance burn 15 to 20 minutes prior to accessing flame appearance):

•Excessive impingement (contact of flame with logs) should not occur.

•Rear burner flames should have yellowish tips; no soot should form at burner flame tips.

•Flames should not raise off of burner (no “lifting” of flame).

Air Shutter Adjustment

The flame can be adjusted to give the proper flame appearance and to prevent sooting on the window or logs by adjusting the position of the primary air shutter (located at the rear center inlet to the burner). The air shutter should be positioned ap- proximately 1/2 open for Natural Gas and approximately 3/4 open for LP Gas. See page 13, Burner Air Shutter.

NOTE: During periods of high natural gas demand, the gas supplier may add “make-up gases” to the pipeline. This addi- tion will change the composition of the supply gas, and may cause a change in burner flame appearance. You may also notice soot formation on the logs and viewing windows. Check with your gas supplier if you suspect a change in the composition of your gas supply.
