AIR SHUTTER ADJUSTMENTS
Be sure burner and logs are properly installed (see FV-41 Log Set In-
stallation Section). After burner has been properly installed and oper-
ated for 20 minutes, small additional adjustments to the air shutter may
be necessary for final flame appearance. These small shutter adjust-
ments can be made by following these procedures:

1. Install logs and glass frame, and burn unit for 20 minutes
2. If flame is too "blue" open Air Shutters until flames turn yellow.
3. If flames are too "orange" or are causing sooting, open Air Shutters
until flames begin to turn blue. NOTE: If sooting does not stop, turn off fireplace & call a Mendota Service Person.
IMPORTANT: Try each new shutter setting for approx. 1/2 hour before making additional changes.
NOTE: Changes in front burner flame can be made by re-arranging the coals as well. Densely packed coals will yield
more glow and blue flames. Loosely packed coals will yield less glow and yellow flames.

VENT DAMPER ADJUSTMENTS
This fireplace is equipped with a vent damper system that can be adjusted using the glass latch tool. Locate damper ad-
justment rod above the glass frame in convection chamber at the center. 127(,IWKLVILUHSODFH¶VYHQWLVterminated verti-

NOT CLOSE the vent damper completely. Adjust position of damper by judging the flame characteristics after 20 minutes
of burn time. If the flames ghost off burners or if sooting occurs [in LPG units], open the vent damper FULLY and work
backwards in increments to determine the correct damper position for that particular installation.
Use a flash light to look into the convection air cavity and note the Damper Position Indicator. Hook glass latch tool in the
hole at the end of the damper rod, SXOORXWZDUGDERXW´DQGWXUQFORFNZLVHWRFORVHWKHYHQWGDPSHU, release. Use a

of the damper.
