:

The following should only be performed by a qualified 

service technician.

Caution:  Label  all  wires  prior  to  disconnection  when 

servicing  controls.    Wiring  errors  can  cause  improper 

and dangerous operation.  Verify proper operation after 

servicing.

1. Annual inspection should be made and the following 

checks performed:

 

When unit is cool, open glass viewing door and inspect 

burner for dirt, soot, and lint accumulations, and removeif 

necessary. If excessive soot accumulation is present on 

burner, have a qualified service technician adjust  

burner for proper combustion.

 

Clean inside of glass viewing door with gas fireplace 

glass cleaner. NEVER attempt to open door or clean  

glass when unit is hot.

 

Check the hot air outlet vents for lint or other accumula-

tions. Never block or restrict vent openings or obstruct 

flow of ventilation air.

 

Check that direct vent pipe, air intake, and flue are open 

and free of soot, blockage, or debris.

 

Check  gaskets  once  a  year.  Gaskets  must  be  tight. 

Replace if necessary.

 

Inspect the pilot system for proper flame. NEVER ADJUST 

THE PILOT until after the gas pressure has been checked 

and supply  lines have been completely bled (this may 

take an hour or more when bleeding through the pilot). 

All pilots are checked and burned at the factory prior to 

shipment. The pilot adjustment screw is located to the 

lower left of the flame height control knob. 

.2  

Adjust the pilot screw to properly size the flames. The 

flames  should  completely  surround  the  thermopile 

and thermocouple and extend across the main burner 

tube ports. Be careful not to back the screw out of its 

threads.

 

Check that the area around the stove is kept clear and 

is free of combustible materials, gasoline, and other  

flammable vapors and liquids.

 

Check  the  millivolt  system  as  per  the  table  on  this 

page.
