TROUBLE SHOOTING MENDOTA GAS DXV FIREPLACE
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; 12"
W.C. LP Gas).
If sooting continues open air shutter on burner (see "Gas Flame Adjust-
ment" below).
If sooting still continues, shut off unit and call Mendota service person.
NOTE:
To clean glass - remove glass and wipe glass with cloth or paper
towel.
2. Humming or whistling
coming from Fireplace.
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. Turning the Hi/Lo Knob
on the control can reduce the noise. Turning down the flame will reduce
the heat output of the unit.
3. A change in flame
appearance or burner
operation.
A. A change in gas pres-
sure.
B. Carbon, dirt or lint
Have your gas supplier check for correct gas 7" W.C. Nat. Gas; 12" W.C.
LP Gas). If flame still needs adjustment see "Flame Adjustment" below.
Clean out carbon, spider webs, lint, etc. from shutter area.
Logs and burner.
NEVER BLOCK AIR INTAKE OR OUTLET VENTS.
FLAME ADJUSTMENT
Be sure burner and logs are properly installed
.
After logs have been properly installed and operated for
one to one and a half 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. One Air Shutter Control is located behind lower hinged grill on the right side. This controls the rear burner shut-
ter. This shutter control controls the rear burner flames. The front burner shutter is of the rotary-type. The front
burner shutter is factory adjusted for Natural Gas at 1/8” open. For LPG, open to a minimum ¼”.
2. Light pilot; install logs and glass, and burn unit for 30 minutes.
3. If flame is too "blue" push Air Shutter Control Knob inward until flame turns yellow.
4. If flame is too "orange" or is causing sooting open shutter until flame begins to turn blue. NOTE: If sooting
does not stop, turn off fireplace & call Mendota Service Person.
5.
IMPORTANT
: Try each new shutter setting approx. 1/2 hour before making additional changes.
NOTE: Changes in front burner flame can be made by re-arranging the coals and rock wool. Densely packed
coals will yield more glow and blue flames. Loosely packed coals will yield less glow and yellow flames.
CAUTION: Any changes in pilot flame length must be made by qualified person only.
