GAS FLAME ADJUSTMENT
During the initial installation, the air shutter opening should be checked to be certain that the shutter is set
correctly at 1/8" to 1/4" open for natural gas and 1/2" minimum open for L.P. gas. NOTE: For altitudes above
5,000 ft., some variations may be required.
Be sure burner and logs are properly installed (see pages 17-27). After burner has been properly installed and
operated for 2-3 hours, small additional adjustments to the air shutter may be necessary for final flame ap-
pearance. These small shutter adjustments can be made by the following procedure:
[NOTE: Very small changes in shutter settings make major changes in flame appearance.]
1.
Air shutter controls are located on the right side of the unit, behind facings or door, next to the glass door
frame.
2. If flame is too "blue," push air shutter knob in (close) in small 1/8" increments until flame turns desired
realistic "orange."
3. If flame is too "orange" or is causing sooting on viewing glass, pull air shutter knob out (open) in approx. 1/8" incre-
ments until sooting stops. IF SOOTING DOES NOT STOP, TURN OFF UNIT AND CALL YOUR MENDOTA SERVICE
PERSON.
IMPORTANT: Try each new shutter setting approx. ½ hr. before making additional changes. NOTE: Changes in front
burner flame can be made by re-arranging the coals and front burner air shutter opening. (See above.)
NOTICE : Initial heater start-up will cause some NON TOXIC “off gassing” of adhesives, gasket binders, paint and other
materials. Most nuisance odors will be eliminated after the first two hours of operation; however, slight amounts may be
present during first 24 hours of initial operation. To eliminate all nuisance odors, continuously operate this wall unit on the
HIGH setting for 4 to 6 hours.
WARNING: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper
and dangerous operation. Verify proper operation after servicing.
