General

■ Havethefireplaceandinstallationinspectedyearly. 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 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.
NOTICE
Do not use ammonia based or abrasive cleaners on the glass, they will permanently
etch the surface. Use an approved gas fireplace glass cleaner such as Kel-Kem or
White off.

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
22. Handle the door carefully, and clean it with non-abrasive,
non-ammonia based 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.
