Burner Removal And Cleaning - Lynx L27F Installation Use And Care Manual

Burner Cleaning & Adjustment
Before removing burners
ensure the gas supply is off
and the knobs are in the
"off" position. Make sure
the grill has completely
cooled before proceeding.
To Remove Brass Burners:
Remove the grill racks and bri-
quette trays. Grasp the burner,
pull it up and slightly to the rear
of the unit so the burner head
comes off the brass orifice at
the front. Angle the burner side-
ways, and remove. Be careful not
to upset the air shutter position.
Brass Burner Cleaning:
Clean the exterior of the burner
with a wire brush. Clear stub-
born scale with a metal scraper.
Clear any clogged ports with a
straightened paper clip. Never
use a wooden toothpick as it
may break off and clog the port.
Shake out any debris through
the air shutter. Use a flashlight
to inspect the burner inlet to en-
sure it is not blocked. If obstruc-
tions can be seen, use a metal
wire coat hanger that has been
straightened out to clean.
Brass 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 con-
version from one gas to another
may make it necessary to adjust
the burners. The flames of the
Grill burners should be visu-
ally checked and compared to
fig. 19-1. 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, or
spider webs. If needed, proceed
with air shutter adjustment.
Figure 17-1 - Showing
proper flame characteristics.
The amount of air which enters
a burner is governed by a sheet
metal disk at the inlet called an
air shutter. It is locked in place by
a set screw which must be loos-
ened prior to lighting the burner
for adjustment (see fig. 19-2).
To Adjust:
1)
Be extremely careful as the
burner may be very hot.
2) If the flame is yellow, indicat-
ing insufficient air, turn the air
shutter counterclockwise to al-
low more air to the burner.
3) If the flame is noisy and tends
to lift away from the burner, indi-
cating too much air, turn the air
shutter clockwise.
4) Once adjusted, turn the burn-
er off and allow to cool. Remove
burner, tighten set screw and
reinstall the briquette trays and
grill racks.

For day-to-day cleaning, see in-
structions on page 15. If burner
inlet is obstructed, use a metal
wire coat hanger that has been
straightened out to clean.
