Lighting Instructions
See pages 27 to 29.

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.
• Ensure proper log placement as per this manual.
• 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 vapours
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
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",
„
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.
Logs may be cleaned periodically with a vacuum to remove soot
„
or other contaminates.
Due to high operating temperatures, this appliance
should be located out of traffic & away from
