LOW HEAT BURNER ADJUSTMENT
The burners on your grill feature an adjustable
'LOW' setting. Fluctuations in gas pressure, gas
conversions, or the quality of the gas itself can
affect burner performance at the 'LOW' setting. It
may be too high, or it may be too low.
TO ADJUST BURNER 'LOW' SETTING:
1. Make sure that the grill is cool.
2. Remove the grates and the radiants covering
each burner so that the burner flames can be
seen during adjustment.
3. Light the desired burner and set it to 'LOW'.
The knob position will be all the way in the
counter-clockwise direction.
4. Pull off the valve control knob by pulling away
from the grill.
5. Hold the valve shaft with pliers and insert a
small flat screwdriver into the valve shaft. At
the bottom of the valve shaft is the adjustment
screw. Turn this screw to adjust flame height,
clockwise to decrease or counter-clockwise to
increase, while looking at the burner flame,
until the flame is at its lowest stable setting.
BURNER FLAME-AIR SHUTTER ADJUSTMENT
Air flow that enters the burner is controlled by the
'Air Shutter'. Each burner is installed, adjusted, and
tested at the factory prior to shipment, however,
fluctuations in gas pressure, gas conversions, and
gas quality can affect performance of the burner. If
this is the case, it may be necessary to adjust the
flame height of the burner.
Flames should be blue in color and stable, with a
slight yellow tip. The bright blue core should be
around 3/8" tall with a total flame height of around
1-1/2". The flames should burn quietly and not
appear to 'lift' off of the burner. If your flames do not
match this description, use the following procedure.
DANGER!
BE EXTREMELY CAREFUL AROUND HOT
BURNERS AND ADJACENT GRILL PARTS!
To Adjust:
1. Remove the grates and both the upper and lower
radiants. Remove a burner per the instructions
in the section entitled 'CLEANING YOUR GRILL'
(gloves recommended).
2. Loosen the set screw found on the air shutter.
Adjust the air shutter and then re-tighten screw.
Reverse order above for re-installation.
3. If the flame is too YELLOW, turn the shutter
counter-clockwise to OPEN UP the shutter to
allow more air flow. See also 'Yellow Burner
Flames' in the section entitled
'TROUBLESHOOTING GUIDE' (see next section). If
the flame is noisy (sounds like a torch) and tends to
'lift' off of the the burner, turn the shutter
clockwise to CLOSE the shutter and reduce the air
flow.
