CUSTOMER INFORMATION AND TROUBLE-SHOOTING
MAXIMUM ALLOWABLE SURFACE TEMPERATURE
Mendota Inserts/Fireplaces comply with UL Standards for maximum surface temperatures on exposed combustible sur-
faces adjacent to the Insert. The Maximum allowable surface temperature is 117° F. over ambient (room) temperature.
Thus, if a room is 70° – 80° the exposed combustible surfaces immediately surrounding the Insert can have a surface
temperature as high as 187° F. – 200° F. (Too hot to touch).
OVER FIRING/UNDER FIRING OF BURNER
NEVER "over fire" units by adjusting gas pressure to increase BTUH above nameplate specifications. Over firing can
cause permanent damage to firebox and deterioration of parts and void warranty.
NEVER "reduce" main burner or pilot flames length to less than 1” .
PILOT OUTAGE AND RE-LIGHTING
If pilot goes out, be sure to wait a minimum of five minutes before attempting to re-light the pilot.
CLEANING VIEWING GLASS
The viewing glass should be cleaned periodically. Exterior glass may be cleaned with cleaner as desired. For Interior
glass, use soap and water. NEVER USE ABRASIVE CLEANERS, NEVER CLEAN GLASS WHILE OPERATING, OR WHEN
GLASS IS HOT.
NOTE:
Additives that are put in gas (both natural and propane) to make it smell can be harmful to glass and can leave
a white film deposit on the glass. This deposit can be removed with cleaners such as KEL KEM “Polish Plus” (# 65-06-
00455, See your dealer for availability).
In some cases (especially propane) additives can cause “crazing” or etching on the glass. Although this is not normal, it
is not covered under the warranty. The solution may be to change propane suppliers.
Sooting is caused by improper installation or operation. At the first sign of "sooting" (usually a thin black film on the Fire-
place viewing glass) the unit must be immediately turned off and the local Mendota dealer promptly informed. Mendota
products are designed and tested to operate without producing any "sooting" when installed and operated correctly.
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.
AGA/ANSI APPROVAL
Gas appliances must be tested and certified by a nationally recognized testing and certification laboratory to ANSI [Ameri-
can National Standards Institute] gas appliance safety standards.
The Mendota Gas Fireplace Insert has been tested and certified by Intertek Testing Services, 8431 Murphy Drive, Middle-
ton, Wisconsin 53562.
The Mendota Gas Fireplace Inserts have met all necessary AGA/ANSI Standards and are fully certified for installation in
any community.
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 continues, 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
Insert.
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 reducing flame
height using the remote control. Turning down the flame will reduce the heat output
of the Insert.
3. A change in flame ap-
pearance or burner op-
eration.
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 adjustment see "Flame Adjustment" below.
Clean out carbon, spider webs, lint, etc. from shutter area.
NEVER BLOCK AIR INTAKE OR OUTLET VENTS.
