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
gaskets to ensure a proper seal.
• An inspection of the burner, vent run, and primary air open-
ings.
• 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 pres-
sure 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. Imme-
diately 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 screens for damage and proper
installation.
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
21. 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", leav-
ing 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 com-
partment, burner, and firebox free from dust and lint.
„ Clean the primary air openings from lint, embers, dust, etc.
Hi-Lo Burner Adjustment: (SIT Nova 820).
