3.3.7 Initial Firing
NOTE: Make sure the pressure relief plate is in place before firing the appliance.
When lit for the first few times, the appliance may emit an odour resulting from evaporation of paint
and lubricants used in the manufacturing process. Open a door or window for ventilation. Anyone
with a respiratory condition may need to leave the room during the initial firings.
Occasionally, after a cold start, vapour may condense and fog the glass, and the flames may be
partially blue. After a few minutes the moisture will disappear and after several more minutes the
flames should become yellow.
NOTE: It may take up to 25 minutes for the flames to reach maximum height.
3.3.7.1 Manifold Pressure Regulator Adjustment
The manifold pressure regulator controls gas input and flame height, and is preadjusted at the factory.
No further adjustment is required. Manifold pressure can be verified only.
3.3.7.2 Pilot Flame Adjustment
For proper operation, the pilot and main burner flames must be steady and not lifting off or floating.
The top 3/8" (10-13 mm) of the thermopile should be engulfed by the pilot flame. The pilot flame
adjustment should be performed by a qualified service person only. To adjust the pilot flame, turn the
pilot adjustment screw counterclockwise to increase, and clockwise to decrease the flame. Ensure
that the pilot flame completely engulfs the thermopile, as shown in Figure 15.
