Inspecting Burners

Continued

If you pilot assembly does not meet these requirements:

turn fireplace off (see To Turn Off Gas to Appliance, page 27)

see Troubleshooting, page 32

BURNER FLAME PATTERN

Figure 56 shows a typical flame pattern.

If burner flame pattern differs from that described:

turn fireplace off (see To Turn Off Gas to Appliance, page 27)

see Troubleshooting, page 32

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,

 

flames will lift or "ghost". This can be danger-

 

ous. Inspect flames after installation to ensure

Figure 56 - Typical Flame Pattern

proper installation and performance.

 

Cleaning and Maintenance

WARNING:Turnofffireplace

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 unlatched, removed, cracked or broken.

WARNING: Do not use abrasive cleaners as this may damage glass. Use a nonabrasive household 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 glass causing lint, dust and other airborne particles to cling to glass surface. During initial start up a slight film may form on glass due to paint curing. Glass should be cleaned several times with a nonammonia, nonabrasive household cleaner and warm water after the first two weeks of operation.Afterwards, clean 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.

WARNING: Only parts suppliedbythemanufacturershould be used when replacing broken or damaged glass door panel

(see Replacement Parts, page 36). This glass door panel is a complete unit. No substitute materials may be used.

Cleaning and Maintenance

Continued

CAUTION: Wear gloves and safety glasses while handling or removing broken glass. Do not remove if glass is hot. Keep children and pets away from glass.

logs

If you remove logs for cleaning, refer to

Installing Logs, Lava Rock and Glowing Embers, page 25, to properly replace logs.

Use a vacuum cleaner to remove any carbon buildup on logs.

Replace log(s) if broken. See Replacement Parts on page 36.

If glass has been broken, carefully remove glass door (see Removing/Replacing Glass Door, page 23). Vacuum all glass pieces with a shop vac.

CAUTION: Do not vacuum if pieces are hot.

Use only the tempered glass door replacement intended for this fireplace (see Replacement Parts, page 36 for detail on ordering). No substitutions may be made. SeeRemoving/Replacing Glass Door, page 23 for instructions for replacing glass door.

WARNING: Do not operate fireplace with the glass door unlatched, removed, cracked or broken.

pilot and burners

Remove ember material before cleaning burners and replace when cleaning is complete.

Burner and controls should be cleaned with compressed air to remove dust, dirt or lint.

Use a vacuum cleaner or small, soft bristled brush to remove excess dust, dirt or lint.

Replace ember material periodically as needed. See Replacement Parts on page 36.

venting system

Conduct annual inspection of venting system following these guidelines:

1.Check areas of venting system that are exposed to the weather for corrosion (rust spots or streaks and, in extreme cases, holes). Have these items replaced immediately by a qualified service person.

2.Remove the vent cap and shine a flashlight into the vent. Remove any foreign material.

3.Check for evidence of excessive condensation. Continuous condensation can cause corrosion of caps, pipes and fittings and can be caused by having excessive lateral runs, too many elbows or exterior portions of the system being exposed to cold weather.

4.Inspect joints to verify that no pipe section or fitting has been disturbed and loosened. Check mechanical supports such as wall straps for rigidity.

Troubleshooting

WARNING: Turn off heater and let cool before servicing. Only a qualified service person should service and repair heater.

CAUTION: Never use a wire, needle or similar object to clean pilot. This can damage pilot unit.

Note: All troubleshooting items are listed in order of operation.
