Customer Information And Trouble-Shooting - Mendota DXV-35 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. During power outages the unit
will "cycle" to prevent over-heating (see Operation During Power Failure,).
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 325 millivolt.
Never lower (reduce) pilot flame below this minimum 325-millivolt setting (see pg. 45). If pilot flame goes out,
always wait 5 minutes before relighting. Always remove glass when 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. 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" (part # 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
normal, it is not covered under the warranty. The solution may be to change propane suppliers.
SOOTING
Sooting is caused by improper installation or operation. However, some small areas of soot deposits on log
surfaces are deemed acceptable. If you observe large soot areas (larger than 1"x1") on log surfaces or signs of
sooting on 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
The fireplace is designed to operate during power outages. Hot air convection may be improved by removing
upper grill of the Millennia Fronts, opening the doors on the Andover and Prairie Fronts and opening the screen
on the Wellington Front.
