Part No. XG0111
Maintenance
WARNING:
Do not attempt to clean glass when hot.
Do not clean glass with abrasive materials as any glass
etching may cause premature glass failure.
CAUTIONS
n
Fireplace gas control must be in the “OFF” position and pilot
and main burners extinguished when cleaning appliance with
a vacuum.
n
Doors and logs can get very hot. Handle only when cool.
General
n
Have the fireplace installation inspected yearly, including a visual
check of the vent system, the burner and the pilot flame. For your
convenience a 1/8" manifold pressure tap is supplied on the gas
valve for a test gauge connection. See Figure 26.
n For Natural Gas this appliance requires a minimum inlet pressure
of 5.5" W.C. and a manifold pressure of 3.5" W.C.
n
For Propane Gas this appliance requires a minimum inlet
pressure of 11" W.C. and a manifold pressure of 10" W.C.
n
Always keep the fireplace area clear and free of combustible
materials, as well as gasoline and other flammable vapours and
liquids.
n
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.
n
Glass must be cleaned periodically to remove any film (which is a
normal biproduct of combustion) which may be visible. Film can
easily be removed by removing the door, as shown on page 13.
Handle the door carefully, and clean it with non-abrasive glass
cleaners. One of the most effective products is Kel Kem.
n
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.
n
Use a vacuum cleaner or whisk broom to keep the control
compartment, burner, and firebox free from dust and lint.
n
Logs may be cleaned periodically with a vacuum to remove soot
or other contaminates.

Pilot Burner Adjustment
1. Locate Pilot Adjustment Screw. (See figure 27.)
2. Adjust pilot screw to provide properly sized flame as shown in
figure 28).
3. After installing or servicing, leak test with a soap solution with main
burner on. Coat pipe and tubing joints, gasket etc. with soap
solution. Bubbles indicate leaks. Tighten any areas where the
bubbles appear until the bubbling stops completely.
