Maintenance
General
Q Have the replace 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 appers and the door gasketing to
ensure a proper seal.
• An inspection of the burner, venturi, and primary air openings.
• An inspection of the gas valve, gas components, and pilot ame. For your
convenience a 1/8" manifold pressure tap is supplied on the gas valve for a
test gauge connection. See Figure 32.
• Inspection of all optional equipment; fans, thermostats, etc.
Q For Natural Gas this appliance requires a minimum inlet pressure of 5.5" w.c.
and a manifold pressure of 3.5" w.c.
Q Always keep the replace area clear and free of combustible materials, as well
as gasoline and other ammable vapors and liquids.
Q Do not use this appliance if any part has been under water. Immediately call a
qualied service technician to inspect the appliance and to replace any part of
the control system and any gas control which has been under water.
Operation
Lighting Instructions
See pages 15 and 16.
Burner Adjustment
The DV 42 ST is equipped with an adjustable burner, allowing you to raise or lower
the ames. To adjust the ames, locate the black knob marked 'Hi-Lo', in the center of
the gas control valve (See Figure 32). The front burners are not adjustable.
Q To raise the ame height, turn the black knob (located behind the lower trim)
counter-clockwise.
Q To lower the ame height, turn clockwise.

Cleaning
When the replace is rst activated, there may be some smoking and a visible lm
may be left on the glass. This is a normal condition, and is the result of burning of
protective coatings on new metal.
Q Glass must be cleaned periodically to remove any lm (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 12. Handle the door carefully, and clean it
with non-abrasive glass cleaners. One of the most eective products is Kel Kem.
Q Silicone seals on inner door during initial ring will "o gas", leaving a visual
deposit of a white substance on combustion chamber walls. This can easily be
removed using normal household products.
Q Use a vacuum cleaner or whisk broom to keep the control compartment, burner,
and rebox free from dust and lint.
Q Linear Burners may be cleaned periodically with a vacuum to remove soot or
other contaminates.

CAUTION!
 Fireplace gas control must be in the “OFF” position and pilot and main
burners extinguished when cleaning appliance with a vacuum.
 Doors can get very hot. Handle only when cool.
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.
