Cleaning and Maintenance
Continued
LOGS
•If you remove logs for cleaning, refer to
Installing Logs and Glowing Embers, page 19, to properly replace logs.
•Use a vacuum cleaner to remove any carbon buildup on logs.
•Replace log(s) if broken. See Replacement Parts, page 31.
•Replace ember material periodically as needed. See Replacement Parts, page 31.
VENTING SYSTEM
Conduct annual inspection of the venting system following these guidelines:
1.Check areas of venting system that are exposed to the weather corrosion (rust
spots or streaks and in extreme cases, holes). Have these items replaced im- mediately by a qualified service person.
2.Remove the vent cap and shine a flashlight into vent. Remove any foreign material.
3.Check for evidence of excessive con- densation. 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 sec- tion or fitting has been distributed and loosened. Check mechanical supports such as wall straps for rigidity.

Service Hints
When Gas Pressure Is Too Low
•pilot will not stay lit
•burners will have delayed ignition
•heater will not produce specified heat
•for propane/LP units, propane/LP gas sup- ply may be low
You may feel your gas pressure is too low. If so, contact your local natural or propane/LP gas supplier.
