Adjustment

To adjust the flame, position the air shutter to the nominal setting (see Figure 7 ). Allow the burner to operate for at least 30 minutes. Observe the flame continuously.

If it appears weak or sooty as previously de- scribed, adjust the air shutter open or closed until desired effect is achieved.

Note: If the flame still appears anemic with the air shutter closed all the way (usually a result of lengthy vertical venting runs), turn off the appli- ance, turn off the gas supply, wait for the parts to cool and access the air shutter. The shutter is prevented from actually closing by a tab that is bent over into the opening. Remove this obstruc- tion by bending back. Reassemble and restart the appliance and after 24 minutes reobserve the flame. Adjust the air shutter as described.
