TROUBLE SHOOTING THE FV-41 FIREPLACE & MAINTENANCE INFORMATION
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 inlet 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 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 ap-
pearance or burner op-
eration.
A. A change in gas pres-
sure.
B. Vent system restricted.
Have your gas supplier check for correct gas 7" W.C. Nat. Gas; 11" W.C. LP
Gas). If flame still needs adjustment see "Flame Adjustment" below.
Clean out carbon, spider webs, lint, etc. from shutter area.

OVER FIRING OF BURNER
NEVER "over fire" units by adjusting gas pressure or drilling out the orifice to increase BTUH above nameplate specifica-
tions. Over firing can cause permanent damage to firebox and deterioration of parts and void warranty.
MAINTAINING CORRECT PILOT-FLAME, PILOT OUTAGE & RELIGHTING
The pilot flame must
be checked during initial installation and annually by a qualified Mendota Technician. This appliance
utilizes Flame Rectification Technology. If the pilot flame is turned down too low, the flame sensor may not detect the pilot
flame and the pilot light may not stay lit. Do not turn down the pilot light flame. Use the IPI mode instead during summer
months.
CLEANING VIEWING GLASS
The viewing glass should be cleaned periodically. Exterior glass surface may be cleaned with cleaner as desired. To
clean interior surface of glass - use soap and water. CAUTION: Do not
use oven cleaner to clean glass. Clean the glass
only when it has cooled to room temperature.
NOTE: Additives that are put in gas (both natural and propane) to make it smell can be harmful to glass and can leave a

SOOTING
Sooting
is caused by improper installation or air shutter operation. However, some small areas of soot deposits on log
surfaces are deemed acceptable. If you observe large soRWDUHDVODUJHUWKDQ´[´RQORJVXUIDFHVRUVLJQVRIVRRWLQJRQ
the door glass (usually a thin black film on the Fireplace viewing glass or on the outside of the home around the vent cap),
the unit must
be immediately turned off and the local Mendota dealer promptly informed. Mendota dealers will correct
"sooting" problems, but Mendota and their dealers are not
responsible for
damage caused by excessive sooting that has not been immediately brought
to their attention.
OPERATION DURING POWER FAILURE
This fireplace is designed to operate during power outages. Blowers and the
Accent Light will not function during power outages. However, all burners will
continue to function normally. Heat output will be reduced slightly without the
blower functioning (approximately 5% less).
GAS SHUTOFF PROCEDURES
This gas fireplace is equipped with a manual ball shutoff valve that is located
on the left side and within the left convection air cavity. The manual ball shutoff
valve is designed to be manipulated using the glass latch tool. Insert bent end
