Lighting Instructions

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
Inspection of all 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 smoke 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. Handle the door
carefully, and clean it with nonabrasive 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.
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.
