Maintenance
Lighting Instructions
See pages 25 to 26.
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 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, 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 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, as shown on
Page
23
. 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 from the chamber
walls using normal household products.
■ Use a vacuum cleaner or whisk broom to keep the control
compartment, burner, and firebox free from dust and lint.
