Inspecting Burners

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

PILOT Assembly

The pilot assembly is factory preset for the proper flame height. Alterations may have occurred dur- ing shipping and handling. Call a qualified service person to readjust the pilot if necessary.

The height of the thermopile must be 3/8" to 1/2" above pilot flame as shown if Figure 54. The thermocouple must be at a height of about 1/8" above the pilot flame. The flame from the pilot burner must extend beyond both the thermocouple and thermopile.

If your pilot assembly does not meet these re- quirements:

•turn fireplace off (see To Turn OFF Gas to Ap- pliance, page 25)

•see Troubleshooting, page 32

BURNER FLAME PATTERN

Burner flames will be steady; not lifting or floating. Flame patterns will be different from unit to unit and will vary depending on installation type and weather conditions.

If the vent configuration is installed incorrectly, the flames will lift or "ghost". This can be danger- ous. Inspect the flames after installation to ensure proper installation and performance.

Figure 55 shows a typical flame pattern.

If burner flame pattern differs from that described:

•turn fireplace off (see To Turn Off Gas to Ap- pliance, page 27)

•see Troubleshooting, page 32

Cleaning and

Maintenance

WARNING: Turn off fireplace and let cool before cleaning.

CAUTION: You must keep control areas, burners, and circulating air passageways of fireplace clean. Inspect these areas of fireplace before each use. Have fireplace inspected yearly by a qualified service person. Fireplace may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.

GLASS DOOR

WARNING: Handle glass door panel with care. Do not strike, slam, or otherwise abuse glass. Do not operate fireplace with the glass door removed, cracked, or broken.

WARNING: Do not use abra- sivecleanersasthismaydamage glass. Use a nonabrasive house- hold glass cleaner to clean glass. Do not clean glass when hot.

Glass must be cleaned periodically. During start- up it is normal for condensation to form on the inside of the glass causing lint, dust, and other airborne particles to cling to the glass surface. During initial start-up a slight film may form on the glass due to paint curing. The glass should be cleaned several times with a non-ammonia, non- abrasive household cleaner and warm water after the first two weeks of operation. Thereafter, clean the glass two or three times during each heating season, depending on the usage and circumstances present. Refer to Removing/Replacing Glass Door on page 24 of this manual when removing glass door for cleaning.
