INSTALLATION
Burner Adjustment
U-burner 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.14. Flames should be blue and
stable with no yellow tips (LP units may have some yellow
tipping), 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. If cleaning the burner ports
and air shutter does not improve performance, you can alter
the air shutter adjustment. The amount of air which enters a
burner is governed by a metal cup at the inlet of the burner
called an air shutter. It is locked in place by a screw which
must be loosened prior to lighting the burner for adjustment.
IMPORTANT!
Before lighting, inspect the gas supply piping or hose prior to turning the gas “on”. If there is evidence
of cuts, wear, or abrasion, it must be replaced prior to use.
U-burner flame height adjustment
Before beginning, ensure the grill is OFF and cool. To access the grill burner air shutters, first
remove the grates and radiants from the firebox, then remove the grill burner using instructions
shown on page 42. With a screw driver, loosen the lock screw on the face of the air shutter slightly
so that the air shutter can be adjusted.
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.
Note: reinstall the U-burner, ensuring it is level. Light the burner and check the flame. If the color
of the flame is blue and the height is stable, remove the burner and tighten the air shutter screw.
If the flames show instability or an inconsistent color, repeat the above procedure to readjust the
air shutter.
Low flame setting adjustment
The valves on the grill feature an adjustable low setting. Due to
fluctuations in gas pressure, heating value or gas conversion,
you may feel it necessary to increase or decrease gas flow in
the low position. We do not recommend adjusting the infrared
rotisserie burner.
To adjust
1 Light the burner.
2 Turn the control knob to the lowest setting (counter-clockwise).
3 Remove the knob.
4 While holding the valve shaft with pliers, insert a thin, flat tipped
screwdriver into the shaft and while viewing the burner adjust to
a minimum stable flame.
For sear burners, a slight flutter will be
present before the flame becomes unstable.
