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 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�
■ 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
29� 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.

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.
