AIR SHUTTER ADJUSTMENTS
Air shutter adjustments are preset at the fac-
tory. These adjustments may need to be re-
done and/or fine tuned by the installer.
These adjustments are normal. They are
the responsibility of the qualified installer
and are not covered by your warranty.
Before attempting to adjust any burner air
shutter, ensure the following has been
checked and is correct:
Proper gas type - match serial plate
Proper regulator setting
Orifice aligned - parallel with the venturi
to the burner
After verifying the gas, regulator and orifices
adjust the air shutter by:
Remove all top cooking sections associ-
ated with the burner(s) to be adjusted.
Use a screwdriver to loosen the air shutter
tightening screw.
Turn the air shutter as required to adjust
the flame - open gap for ―lazy‖ flame,
close gap for ―lifting‖ flame.
Test burner.
If necessary, turn off burner and readjust.
Turn off burner, tighten shutter screw and
replace top sections when complete.
A properly adjusted burner will have a coni-
cal shaped blue flame, however, on some lar-
ger burners (18K) the cones are close together
and blend into one another. Yellow tips nor-
mally flicker occasionally with natural gas,
more often with propane. The flame should
be almost all blue all the time.
All specifications are subject to change without prior notification
CARE AND MAINTENANCE
Please Note:
Opening the air shutter gap will eliminate the yel-
low tipping on the burner. Closing the air shutter
gap will prevent a noisy flame that lifts off the
burner port.
