Maintenance
Lighting Instructions
See pages 21 to 22.
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 vapors 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
(a normal by-product of combustion) which may be
visible. Film can easily be removed by removing the
door, as shown on Page 19. 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
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.
Hi-Lo Burner Adjustment: (SIT Nova 820).
The DV 42* is equipped with an adjustable burner, allowing
you to raise or lower the flames. To adjust the flames, locate
the black knob marked 'Hi-Lo', in the center of the gas control
valve (See Figure 32).
•
To raise the flame height, turn the black knob (located
behind the lower trim) counter-clockwise.
•
To lower the flame height, turn clockwise.

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.
