Each outdoor appliance burner is tested and adjusted at the factory prior to shipment; however, variations in
the local gas supply or a conversion from one gas type to another may make it necessary to adjust the burners.
The flames of the burners should be visually checked and compared to that of the drawing in Fig. 35. 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, spider webs, etc. Proceed with air shutter adjustment.
The amount of air which enters a burner is governed by a sheet 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.
OUTDOOR APPLIANCE BURNER FLAME HEIGHT:
To access the outdoor appliance burner air shutters, first remove
the valve panel by removing it the same way as described on page
20, section “Before Testing”. With a screw driver, loosen the lock-
screw on the face of the air shutter. Light the burner and adjust
according to the directions (Fig. 35).
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
counterclockwise to allow 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 burner off and reverse steps to reassemble.
LOW SETTING ADJUSTMENT:
The valves on the outdoor appliance 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.
To Adjust:
1.
Light the burner.
2.
Turn the control knob to the lowest setting (all the way 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 (Fig. 36).
WARNING: 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.
