Connecting the Gas Supply & Testing the Flame
4. TEST PRESSURE THROUGH CONTROL VALUE
Test pressure to and through the control valve using a
manometer on the test gauge taps on the control valve. The line
must be tested as follows:
Propane (LPG or LP):
10.0" w.c.manifold pressure
11.0" w.c.minimum inlet supply for adjustment
Natural gas:
3.5" w.c.manifold pressure
5.0" w.c.minimum inlet supply for adjustment
5. LIGHT THE FIREPLACE, FOLLOWING LIGHTING
DIRECTIONS ON PAGE 21. (FRONT GLASS AND
FRONT CASTING MUST BE IN PLACE PRIOR
TO LIGHTING)
6. The Air Shutter
covers the end of the venturi opening at the
base of the Burner Pan and controls the air/fuel mixture. The
Shutter has been pre-set to provide an optimum yellow flame at sea
level when the Logset is warmed up.
If you are operating a Natural Gas Fireplace at an elevation other
than sea level, it may be necessary to adjust the position of the air
shutter. Wait fifteen minutes after first lighting the Burner to see if the
flame changes from mostly blue to bright yellow. If it remains blue
then there is too much air getting into the mix. If the flame turns
orange or smoky then there is too little air getting into the mix.
To adjust the amount of air:
Note: Allow Fireplace to cool before handling.
a. Remove the Front casting (see illustration 9.1).
b. Remove the Glass Front (see illustration 9.3)
c. Carefully lift and remove the Logset.
d. Remove the Glass Window Retainer by removing the two
screws and then remove the single screw that attaches the
Burner Pan to the Front casting (see illustration 11.3)
e. Lift the Burner Pan off the front tabs of the Firebox and pull
the Pan out carefully so that the orifice at the rear is not
damaged. Natural Gas Fireplace owners should leave the Air
shield attached to the Burner Pan and remove both as one
piece. (see illustration 11.4).
f. Adjust the Air Shutter by loosening the Screw (see illustration
11.5). Open the Shutter wider for more air or close it for less
air.
