GENERAL INFORMATION
Your Mendota Gas Fireplace Insert has a state-of-the-art 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.
SAFETY AND STRUCTURAL CONCERNS:
The D-40 Fireplace Insert must be installed and serviced by a Mendota approved serviceperson. Any adjustments to
burner, pilot, logs or coal bed must be made by a Mendota approved service person. Pilot flame must be checked with a
voltmeter. Pilot flame must register a minimum of 325 on (DC) millivolt meter. If pilot goes out, always wait five (5)
minutes before relighting pilot.
ALWAYS REMOVE THE GLASS WHEN LIGHTING THE PILOT
. The burner
must light immediately and the flame must travel promptly and smoothly around "curve" and light entire burner. The
flame must not "lift" off the burner.
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 when this
insert is installed at floor level.
VENTING REQUIREMENTS:
Use only Mendota specified vents and vent caps when installing your fireplace insert. All vent pipe sections must be
tight and leak proof.
HEATING PERFORMANCE
The Mendota D-40 Fireplace Insert is a true, high efficiency gas heater. With a heat output of 32,000 BTUH, the Mendota
Insert will usually heat a large area of your home if situated to maximize heat circulation.
NOTE:
The Mendota Insert is
designed as a supplemental heat source. It should not be used as a whole house heating system. Supplemental air movement
considerations for maximizing heat circulation are: through-the-wall grills, floor grills, ceiling fans, or the continuous
operation of central heating and cooling blowers. The most EFFICIENT and successful method for overall heat distribution
is a ceiling fan.
Additional information on heat is given on Pg. 31 "Customer Information". The heat output of the Insert can
be reduced by up to 13,000 BTUH by slowly turning the Hi/Lo temperature knob on the front of the gas valve
counterclockwise from "Hi" to "Lo". Heat output can be further reduced to 6,500 BTUH by turning off the rear burner. The
blowers can also be turned down to reduce heat output.

ELECTRICAL REQUIREMENTS
A 120-volt electrical service must be supplied at the fireplace location at the time of installation.
The blowers must be electrically grounded in accordance with local codes or in the absence of local codes, with the National
Electric Code ANSI/NFPA 70-1987. The blowers are equipped with a three-prong (grounding) plug for your protection
against shock hazard and should be plugged directly into a properly grounded three-prong receptacle.
DO NOT CUT OR
REMOVE THE GROUNDING PRONG FROM THIS PLUG!
If an optional thermostat is installed, thermostat wire should be run from desired thermostat location (or "on/off" switch) to
the gas control (located behind lower grill) — see optional thermostat installation section. Inlet holes are provided on left
and right sides for electrical and gas connections.
