AIR SHUTTER ADJUSTMENTS
Be sure burner and logs are properly installed (see FV-41 ARCH Log
Set Installation Section in the Owner’s Manual). After burner has been
properly installed and operated for 20 minutes, small additional ad-
justments to the air shutter may be necessary for final flame appear-
ance. These small shutter adjustments can be made by following the-
se procedures:
NOTE: Start with the rear burner air shutter set at 1/8” open for NG
and ¼” open for LPG. Both the Front and Rear burner shutters
can be manipulated with the fireplace operating.
Opening the shut-
ter will yield shorter and blue(er) flames and closing the shutter will
yield taller and yellow(er) flames.
The front burner air shutter adjustment lever is located below the Glass
Door Frame on the left side. Slide the lever to the “left” to CLOSE and to
the “right” to OPEN the front burner shutter.
The rear burner air shutter adjustment lever is located below the Glass
Door Frame on the right side. Slide this lever to the “right” to CLOSE
and to the “left” to OPEN the rear burner shutter.
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.
4. For NG applications, start with the rear burner air shutter open 1/8”. For high altitude applications, air shutter may
need to be open further.
5. For LPG applications, start with the rear burner air shutter open ¼”. For high altitude applications, air shutter may
need to be opened further.
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. NOTE: If this fireplace’s vent is terminated verti-
cally, the damper position may be FULL OPEN or FULL CLOSED. If this fireplace’s vent is terminated horizontally, DO
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, pull outward about 1/8” and turn clockwise to close the vent damper, release. Use a flashlight to inspect the
damper position. The base of the damper adjustment rod has a pointer that indicates the position of the damper.
