NOTE
Burner Air Adjustment:
The air shutter has been factory preset to the proper
operation between sea level and 2000 feet elevation at standard conditions,
(60°F ambient water, and air temperatures).
In cooler temperatures or higher altitudes, it may be necessary to adjust the air
supply to the combustion chamber. This adjustment will maximize burner
efficient operation or excessive soot buildup on the heat exchanger coil. A
smoke spot test is recommended during any air shutter and band adjustment. If
you do not have the equipment to perform a smoke spot test, follow the
procedures listed below.
Figure 1. Burner Air Adjustment.
BURNER AIR ADJUSTMENT PROCEDURES:
1. The water heater must be operating and heating water.
2. Loosen the locking screw on the air shutter.
3. Check for smoke from the heat exchanger exhaust. If smoke is not present, slowly close the air shutter by
moving the dial counterclockwise (CCW) to a lower number. Continue moving the dial CCW until smoke
appears.
4. Record the setting.
