Customer Information And Trouble Shooting - Mendota DXV-42 Installation & Operating Instructions Manual

CUSTOMER INFORMATION AND TROUBLE-SHOOTING
MAXIMUM ALLOWABLE SURFACE TEMPERATURE
Mendota Fireplaces comply with UL Standards for maximum surface temperatures on exposed combustible
surfaces adjacent to the unit. 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
Fireplace can have a surface temperature as high as 187° F. – 197° F. (too hot to touch). The continuous
blower operation automatically keeps temperatures within these safety limits.
OVER FIRING OF BURNER
NEVER "over fire" units by adjusting gas pressure or drilling out the orifice to increase BTUH above
nameplate specifications. 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 with millivolt meter and must always be a minimum of 460 millivolts.
Never lower (reduce) pilot flame below this minimum 460 millivolt setting. (See pg.31.)
If pilot goes out, be sure and wait a minimum of 5 minutes before re-lighting. Always remove glass door
before lighting pilot.
CLEANING VIEWING GLASS
The viewing glass should be cleaned periodically. Exterior glass may be cleaned with cleaner as desired.
Interior glass - use soap and water, Kel Kem Glass Cleaner or equivalent. CAUTION: Do Not use oven
cleaner to clean glass.
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) or comparable product (See your dealer).
In some cases (especially propane) additives can cause "crazing" or etching on the glass. Although this is
not a common occurrence, it is not covered under the warranty. The solution may be to change propane
suppliers.
SOOTING
Sooting is caused by improper installation or operation. At the first sign of "sooting" (usually a think 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 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.
OPERATION DURING POWER FAILURE
The fireplace is designed to operate during power outages. Hot air convection may be improved by remov-
ing upper grill during power outage situations.
