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.
