Burner Flame / Air Shutter Adjustment - Delta Heat DHBQ26G-D Installation, Use & Care Manual

BURNER FLAME / AIR SHUTTER ADJUSTMENT

Each grill burner is tested and adjusted at the
factory prior to shipment; however, variations in the local
gas supply may make it necessary to adjust the burners.
The flames of the U-burners should be visually
checked. Flames should be blue and stable with little
to no yellow tips, no excessive noise or lifting. If any of
these conditions exist, remove the burner and check to
see if the air shutter or burner ports are blocked by dirt,
debris, spider webs, etc. If it is clear, the air shutter may
need to be adjusted.
Before adjusting the air shutter, verify that the correct orifice size for the gas type was in-
stalled.
ADJUSTING THE GRILL BURNER FLAME
The amount of air is controlled by a sheet metal cup at the inlet of the burner called an air shut-
ter. It is locked in place by a set screw which must be loosened prior to lighting the burner for adjust-
ment. The air shutter adjustment screws are accessible with a phillips screwdriver. Loosen the lock
screw of the air shutter. Adjust according to the following directions. Be careful as the burner and
other grill parts may be very hot!
• If the flame is yellow, indicating insufficient air, turn the air shutter counter-clockwise to allow
more air to the burner.
• If the flame is noisy and tends to lift away from the burner, indicating too much air, turn the air
shutter clockwise.
Remember to tighten the set screw prior to re-installing the burner.
ENSURE THAT THE BURNERS ARE SITTING PROPERLY ON THE ORIFICES BEFORE LIGHT-
ING THE BURNERS.
