Section 10: Cleaning and Maintenance
General
• Have the fireplace and installation inspected yearly. The inspection
must include, but is not limited to, the following:
• A visual check of the entire vent system and termination, where
accessible.
• An inspection of the explosion relief flappers and the door
gaskets to ensure a proper seal.
• An inspection of the burner, vent run, and primary air openings.
• An inspection of the gas valve, gas components, and pilot flame.
For your convenience a 1/8" manifold pressure tap is supplied
on the gas valve for a test gauge connection.
• Inspection of all optional equipment; fans, thermostats, remote
control lights, etc.
• For Natural Gas this appliance requires a minimum inlet pressure
of 5.5" W.C. and a manifold pressure of 3.5" W.C.
• For Propane Gas this appliance requires a minimum inlet pressure
of 11" W.C. and a manifold pressure of 10" W.C.
• Always keep the fireplace area clear and free of combustible materials,
as well as gasoline and other flammable vapors and liquids.
• Do not use this appliance if any part has been under water.
Immediately call a qualified service technician to inspect the appliance
and to replace any part of the control system and any gas control
which has been under water.
• Inspection of glass doors and screen for damage and proper
installation.
Cleaning
When the fireplace is first activated, there may be some smoke and a
visible film may be left on the glass. This is a normal condition, and is
the result of burning of protective coatings on new metal.
• Glass must be cleaned periodically to remove any film (which is
a normal by-product of combustion) which may be visible. Film
can easily be removed by removing the door. Handle the door
carefully, and clean it with non-abrasive, non-ammonia based
glass cleaners. One of the most effective products is Kel-Kem.
• During the initial firing, Silicone seals will "off gas", leaving a
visual deposit of a white substance on combustion chamber
walls. This can easily be removed using normal household
products.
• Use a vacuum cleaner or whisk broom to keep the control
compartment, burner, and firebox free from dust and lint.
NOTICE
Do not use ammonia or abrasive cleaners on the glass, they will
permanently etch the surface. Use an approved gas fireplace cleaner
such as Kel-Kem or White off.

2. Adjust pilot screw to provide properly sized flame as shown.
3. After installing or servicing, leak test with
a soap solution with main burner on. Coat
pipe and tubing joints, gasket etc. with soap
