GRILL BURNER FLAME HEIGHT
To access the grill burner air shutters first remove the valve panel by removing the four screws on the
corners of the valve panel. Remove the control knobs. Pull the valve panel outward. Do not pull on
the igniter wires. The valve panel can be unplugged from the unit. If so, the unit will have to be match
lit during burner adjustments. With a screw driver, loosen the lock-screw on the face of the air shut-
ter. Light the burner and adjust according to the directions below. Access for the power burner air
shutters is through the top after removing the top burner grate (See Figure 09).
BURNER AIR ADJUSTMENT
Each grill burner is tested and adjusted at the factory prior to shipment; however, variations in the
local gas supply or a conversion from one gas to another may make it necessary to adjust the burners.
The flames of the burners (except the rotisserie burner) should be visually checked and compared to
that of the drawing in (Fig.08). Flames should be blue and stable with no yellow tips, excessive noise
or lifting. If any of these conditions exist, check if the air shutter or burner ports are blocked by dirt,
debris, spider webs, etc. Proceed with air shutter adjustment. The amount of air which enters a burner
is governed by a sheet metal cup or disk at the inlet of the burner called an air shutter. It is locked in
place by a set screw which must be loosened prior to lighting the burner for adjustment.
TO ADJUST
1)
Be careful as the burner may be very hot.
2)
If the flame is yellow, indicating insufficient air, turn the air shutter counter-clockwise to
allow more air to the burner.
3)
If the flame is noisy and tends to lift away from the burner, indicating too much air, turn the
air shutter clockwise.
4)
Once adjusted turn the burner off and reverse steps to reassemble.
