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.
• An inspection of the explosion relief flappers and the door
gasketing to ensure a proper seal.
• An inspection of the burner, venturi, 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. See Figure 32.
• Ensure proper log placement as per this manual.
• Inspection of all optional equipment; fans, thermostats, 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.
Cleaning
When the fireplace is first activated, there may be some smoking 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, as shown on page
15. Handle the door carefully, and clean it with non-abrasive glass
cleaners. One of the most effective products is Kel Kem.
 Silicone seals on inner door during initial firing 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.
Logs may be cleaned periodically with a vacuum to remove soot or

other contaminates.
WARNING!
Do not attempt to clean glass when hot.
Do not clean glass with abrasive materials as any glass etching
may cause premature glass failure.
Do not operate this fireplace without the glass door, or with a
broken glass door.
