Mendota DXV-42 Installation & Operating Instructions Manual page 4

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 opera-
tion.
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 460 on millivolt meter. If pilot goes out always wait five (5) minutes before relighting pilot.
ALWAYS REMOVE THE GLASS DOOR 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. All vent
pipe sections must be "twist locked" and all inner pipe joints (Simpson Duravent type only) must be sealed and leak proof using
2000F Silicate Sealant.
The Mendota Direct Vent Fireplace may be placed within inches of adjacent sidewalls. (See
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 as
mantels or mantels with steel protector plate on underside maybe installed at any desired height above upper grill.
NEVER BLOCK OFF UPPER OR LOWER GRILLS. ALWAYS USE MENDOTA GRILLS, MENDOTA VENT SYSTEMS
AND MENDOTA APPROVED VENT CAPS.
A non-combustible hearth protector is required and must extend a minimum of 16" in front of the fireplace
for raised hearths).
VENTING REQUIREMENTS:
Use only Mendota approved vents and vent caps when installing your fireplace. Closely follow venting locations, directions and
requirements (see pages 8-17). Observe the restrictions relating to vent position on exterior of home
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 ceil-
ing fan. The most efficient method for overall heat distribution is a ceiling fan. The heat output of the Fireplace can be re-
duced by up to 13,000 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 120 volt electrical service must be supplied at the fireplace loca-
tion 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 di-
rectly 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. Note: There will be delays in blower operation during "heat-up"
(approx. ½ hr.) and extended blower operation during "cool-down" (approx. ½ hr.) of unit (see Blower Wiring Diagram
pg. 26).
Thermostat wire should be run from desired thermostat location (or "on/off") switch to the fireplace terminals (located behind
lower grill) – see thermostat installation section (pg.27).
