GENERAL INFORMATION
Your Mendota Gas Fireplace has a state-of-the-art co-axial direct vent, sealed combustion system. This advanced, highly efficient
system brings in outside air for combustion has a separate exhaust vent and efficiently heats and re-circulates room air. The Mendota
system maintains high air quality, maximizes efficiency and assures proper operation in today's "tight" homes.
SAFETY AND STRUCTURAL CONCERNS:
The DXV Fireplace must
be installed and serviced by a Mendota approved service person. Any adjustments to burner, pilot, logs or
coal bed must
be made by a Mendota approved service person. Pilot flame must be checked with voltmeter. Pilot flame must register
a minimum
of 325 on Millivolt meter. If pilot goes out always wait five (5) minutes before relighting pilot. ALWAYS
VENTING REQUIREMENTS: See Page 5 for specific information on venting options.
This Mendota Fireplace can be vented using AMERIVENT, DURAVENT, SELKIRK METALBESTOS, SECURITY CHIMNEY
brands of coaxial pipe off the top or using 5”x8” coaxial pipe off the rear.. For instructions and specifications for venting off the rear,
see the Instructions included with this Manual. Use only Mendota specified vents and vent caps when installing your fireplace.
Closely follow venting locations, directions and requirements. Observe the restrictions relating to vent position on exterior of home
(see pg. 8). Be sure all vent pipe sections are fully twist-locked and leak-proof. Be sure 1000
º Silicate Stove Sealant is used on the
inner pipe joints of all Simpson DuraVent pipe components and all adjustable pipe sections manufactured by Simpson DuraVent and
American Metals.
REMOVE THE GLASS WHEN LIGHTING THE PILOT. The burner must light immediately & the flame must
travel promptly and smoothly around "curve" and light entire burner. The flame must not
"lift" off burner. DO NOT operate unit if
burner does not light immediately or if flame lifts off burner.
The Mendota Direct Vent Fireplace may be placed within inches of adjacent sidewalls. (See Figure 4: Specifications & Clearances
on pg. 12 and pg. 22). The fireplace may be placed directly on concrete or wood flooring. If the appliance is to be installed on
carpeting, vinyl or other combustible material other than wood flooring, the appliance shall be installed on a metal or wood panel
extending the full width and depth of the appliance. Combustible mantels must be installed at a minimum of 14" above top of the heat
outlet grill and no more than 8" out from wall (see Figure 4: Specifications & Clearances, pg. 12 and pg. 22). Non-combustible
(marble, brick, stone, etc.) mantels or mantels with steel protector plate on underside can be installed at any desired height above
upper grill.
Never block off upper or lower grills. Always use Mendota grills and Mendota approved vent systems and vent caps.
A non-combustible hearth protector is required and must extend a minimum of 12" in front of the fireplace. If fireplace is raised off
floor 6" or more, no hearth protector is required.
HEATING PERFORMANCE:
Mendota Gas Built-in Fireplaces are true, high efficiency gas heaters. With its high heat output the Mendota Fireplace will heat a
large area of your home if situated to maximize heat circulation. Air movement options for maximizing heat circulation, which can be
considered, are through-the-wall grills or floor grills, the continuous operation of central heating furnace blowers, or ceiling fan. The
most efficient method for overall heat distribution is a ceiling fan. The heat output of the Fireplace can be reduced by up to
11,000 BTUH by slowly turning the Hi/Lo temperature knob on the gas valve counter clockwise from "Hi" to "Lo". Blower can also
be turned down to reduce heat output.
AESTHETIC CONSIDERATIONS:
Burning or static fireplaces are a major aesthetic focus in any room. Locate your gas fireplace as you would a television set. The
Mendota Hearth Gas Fireplace will be a continuing source of comfort and fascination. Corner installations will afford you the
greatest potential for viewing in many rooms.
We suggest installing the Mendota Fireplace 6 to 12 inches above the floor by utilizing an elevated hearth.
ELECTRICAL REQUIREMENTS:
A blower is standard on your Mendota Direct Vent Fireplace. A 115 volt electrical service must be supplied at the fireplace location
at the time of installation. It must be electrically grounded in accordance with local codes or in their absence with current edition of
the National Electric Code ANSI/NFPA 70. Power supply to blower must be continuous. DO NOT use switch or variable control in
power supplied to fireplace.
The blower on this appliance is equipped with a three-prong plug for protection against shock hazard and should be plugged directly
into the grounded three-prong receptacle provided with the fireplace. Do not cut or remove the grounding prong from the plug.
NOTE: The blower output can be adjusted with the rheostat. There will be delays in blower operation during "heat-up" (approx.
½hr.) and extended blower operation during "cool-down" (approx. ½ hr.) of unit (see Blower Wiring Diagram pg. 42).
Thermostat wire should be run from desired thermostat location (or "on/off") switch to the gas control (located behind lower grill) –
see thermostat installation section (pg. 41).
