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

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.
See Lighting Instructions section.
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.
