6 MAINTENANCE INFORMATION
6.1 REQUIRED PERIODIC INSPECTIONS
1. Check to verify that the vent system and vent cap are open and free of blockage.
2. Have qualified service person check the operation of the pilot light. Pilot light must light within the first five to eight
seconds of ignitor sparks initiation. If it takes more ten seconds to ignite the pilot flame, check pilot spark rod position and
ignitor wires for pinched areas or damaged areas.
3. Pilot rectification time must be checked. Pilot flame should rectify the
ignition system within five seconds of pilot flame ignition and sparking at
pilot must stop with five seconds. If pilot flame ignites but sparking
continues at pilot hood after five seconds, it indicates that pilot flame
sensor is dirty. Clean pilot flame sensor using emery cloth and retry. If
problem persists, check flame sensor lead wire for damage or grounding
problems and correct.
4. Periodic visual check of pilot flames is required. Pilot Flame must overlap
Flame Sensor and burner ignition ports always. Especially for LPG
applications, always verify visible pilot flame length is at least 1" long,
minimum.
5. Cycle the burners to make certain burner ignition is prompt and flame
propagation along burner length is quick and smooth. If flame
propagation is delayed, remove obstructing debris, vacuum burner ports
and retry.
6. Periodic visual check of rear and front burner flames pattern is required.
6.2 CLEANING VIEWING GLASS
W A RNING: Do not c le an whe n glass is hot.
The viewing glass should be cleaned periodically. Exterior glass surface may be cleaned with cleaner as desired. To clean
Interior glass surface, remove glass frame assembly.
See 4.5 To Remove Door
. U se Kel Kem “polish plus" (part # 65 -06-
00455) or comparable product to clean glass interior surface. Do not use oven cleaner or abrasive cleaners to clean glass.
6.3 REQUIRED ANNUAL MAINTENANCE
In addition to the “Re quir e d Pe r iodic Inspe c tions”, the following pr oc e dur e s m ust be pe r for me d e ac h ye ar by
a qualifie d installe r , se r vic e age nc y or the gas supplie r . A ny adjustme nts to bur ne r , pilot or logs must be
done by a qualifie d installe r , se r vic e age nc y, or the gas supplie r .
Clean all lint and dust build-up around the control and blowers. Inspect the condition of any wiring under the burner for melting
or damage. Clean flame sensor rod/hook using emery cloth. Vacuum all burner ports and pilot assembly.
Remove logs & coals and clean away any foreign matter (lint, Carbon, etc.) on the burner and logs. Be sure the burner ports are
"open". Clean the pilot and under side of the logs for any Carbon deposits.
NO TE: L ogs should be visually c he c ke d for Car bon "build -up". If he avy c ar bon de posits ar e visible on logs,
unit should be tur n e d off and a qualifie d installe r , se r vic e age nc y, or the gas supplie r should be c ontac te d .
Be sur e logs ar e r e -installe d pe r instr uc tions.
Check glass gasket seal. Visually inspect glass gasket, especially at the corners of the glass piece. Glass gasket is installed as a 4-
piece assembly. Check joints between the gasket pieces at the corners. They should butt against each other to create a seal. Gaps
between gasket pieces can cause exhaust leaks and lead to acrid smell concerns.
