TROUBLE SHOOTING MENDOTA GAS FIREPLACE INSERT
SYMPTOM PROBABLE CAUSES CORRECTIVE ACTION
1. Thin black coating [soot]
forms on viewing glass.
A. Incorrect gas pressure
B. Not enough combustion air
Have gas supplier check for correct gas pressure [7"
W.C. Nat. Gas; 11" W.C. LP Gas].
If sooting continues open-air shutter on burner [see
"Gas Flame Adjustment" below]. If sooting still con-
tinues, call a Mendota dealer.
NOTE: To clean glass - remove glass and wipe glass
with cloth or paper towel.
2. Humming or whistling
coming from Fireplace In-
sert.
A. Normal operating noise.
Some noise is normal. It is caused by the gas supply
flowing through the gas orifice. It is expected from
any gas fireplace. The noise can be reduced by turn-
ing the Hi/Lo Knob on the control. Turning down the
flame will reduce the heat output of the Insert.
3. A change in flame ap-
pearance or burner oper-
ation.
A. A change in gas pressure.
B. Carbon dirt or lint.
Have your gas supplier check for correct gas 7" W.C.
Nat. Gas; 11" W.C. LP Gas]. If flame still needs ad-
justment see "Flame Adjustment" below.
Clean out carbon, spider webs, lint, etc. from shutter
area.
NEVER BLOCK AIR INTAKE OR OUTLET VENTS.
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 alti-
tudes above 5,000 ft., some variations may be required.
Be sure burner and logs are properly installed (see pages 15-27). After burner has been properly in-
stalled and operated for 2-3 hours, small additional adjustments to the air shutter may be necessary for
final flame appearance. 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" increments 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.)
