MD44-DV Direct Vent Vented Fireplace
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 6.
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 10.5" 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 12.
Handle the door carefully, and clean with normal liquid household
products.
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
and other contaminates.
