6.5.3 Flame and Air Shutter Adjustment
Inspect the flame of each burner to determine whether adjustments to the burner air shutter are
necessary. Adjust an air shutter if:
•
the tips of the flame appear too yellow. The shutter should be turned to allow MORE air to
enter the burner cavity.
•
the flames appear to be lifting off the burner ports. The shutter should be turned to allow LESS
air to enter the burner cavity.
i
IMPORTANT
Proper burner adjustment would provide a 5/16” stable blue flame at the
full rate (gas valve at High).
Before inspecting the flames, ensure:
•
i
The unit is running at the gas pressure stated on the rating plate.
•
Gas valves are on HIGH.
•
ALL radiants are in place.
To adjust a burner air shutter:
1. Remove the knobs and valve panel (see “6.2 Valve Panel”) to access the front of the burners.
WARNING
Remove power supply to the unit before opening panels for servicing.
2. Restore power supply to the unit. Then turn on the burners using the appropriate ON/OFF
switch.
i
The High-Low gas valves have NO OFF position.
3. Locate the aeration shutter on the burner (see illustration below).
4. Use #2 Philips screwdriver to loosen the screw for the aeration shutter to turn freely.
5. Rotate the air shutter to obtain 5/16” stable, sharp inner blue cones.
