LENNOX CRESTLINE™ SERIES B-VENT GAS FIREPLACES • 36"/42" LSBV MODELS • CARE AND OPERATION INSTRUCTIONS

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.
