General
Have the fireplace and installation inspected yearly. The inspec
-
tion 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 open-
ings.
• 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 optional equipment; fans, thermostats, etc.
For Natural Gas this appliance requires a minimum inlet pres-
sure of 5.5" W.C. and a manifold pressure of 3.5" W.C.
For Propane Gas this appliance requires a minimum inlet pres-
sure 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.
Inspection of glass doors and screens for damage and proper
installation.
Cleaning
When the fireplace is first activated, there may be some smok
-
ing 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, as shown
on Page 21. 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 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.
Clean the primary air openings from lint, embers, dust, etc.
Hi-Lo Burner Adjustment: (SIT Nova 820).
The L52DF-ST* 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 centre of the gas control valve
(See Figure 21).
To raise the flame height, turn the black knob (located be
-
hind the lower control compartment) counter-clockwise.
To lower the flame height, turn clockwise.
