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 FV-44i 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. If pilot
goes out, always wait five (5) minutes before relighting pilot The flame must not "lift" off the burner.
ALWAYS USE MENDOTA FACINGS, MENDOTA VENT SYSTEMS AND MENDOTA APPROVED VENT
CAPS. ONLY DOORS CERTIFIED WITH THE APPLIANCE SHALL BE USED.
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 FV-44i I Fireplace Insert is a true, high efficiency gas heater. 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. "Customer Information". The heat output of the Insert can be reduced by using the down
arrow on the Remote Control – see pg. 23. Heat output can be further reduced by turning off the rear burner using the remote control. 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!

INSTALLATION INSTRUCTIONS
CAUTION: Each installation must conform to all local, state and national codes. Refer to the national fuel gas code and local zoning and code authorities
for details on installation requirements. The Mendota Inserts must be vented to the outside in accordance with the latest edition of the National Fuel Gas
Code. In the absence of local codes, the installation must conform with National Fuel Gas Code ANSI Z223.1 (NFPA 54), or Canadian Code CAN1-B149
or most current edition, also known as NFPA 54. Do not connect this Insert to a chimney flue serving a separate solid fuel or gas-burning appliance.
1. Remove glass doors, metal fire screens, etc. from existing fireplace. Be sure there is 12" minimum
distance from top of upper grill to bottom of mantel; see Specifications (Pg.4 & 5), and a 16" minimum non-combustible hearth extension in front of the glass surface if a raised hearth is not supplied. (See pg. 10 for "Raised Hearth").
2. Remove any additional framework or other obstructions in the existing fireplace opening and burning area. Also remove any chimney cap from top of chimney so that vent liner can be installed
freely.
3. Before Insert is installed, have gas supplier or contractor run gas line to the existing fireplace. Be
sure gas plumbing instructions [see Pg. 11 & 12 are carefully followed. Gas supply may enter fireplace on either side or back of fireplace, whichever is most convenient and accessible. Electrical
service (120 volt) should also be supplied [See electrical requirements on Pg. 3 and blower instructions on Pg. 26].
4. The entire chimney should be swept to remove creosote, soot and any obstructions (bird nests,
etc.).
5. Open fireplace damper. If damper opening is large enough to accept the 4" and 3" flue liners,
permanently secure damper in "open" position. NOTE: Massachusetts requires that the flue dam-
per must be removed or permanently welded in the "open" position.
6. If damper opening is too small for the 4" & 3" flue liners, it will be necessary to remove the damper
handle and the damper plate. Some damper plates are held in place by a pinned hinge that can be
released easily by tapping out the pin with a hammer and punch. Others may be held in place by a
screw or bolt, or pivots may be cast into the damper housing. The latter types may be harder to
get out and may require sawing or breaking out. [NOTE: if flue size is 6" (127 mm) or less, or if
severe offsets occur, or a significant mortar slop is evident between the liners, try to snake liner
down the chimney to the top of the damper housing before breaking out damper plate and housing.]
CAUTION: If the 4" & 3" flue liners cannot be installed in an extremely tight chimney DO NOT proceed with installation.
7. If damper opening is narrower than 4-1/2" to 5" (114 mm to 127 mm) and if local code authorities
allow, loosen and remove mortar behind back side of damper housing in the center of the opening
enough to get the gripping teeth of a pipe wrench over the flange of the damper housing (for cast
iron housings). Tighten the wrench snugly, and kick down on the wrench handle to break out a
half moon shaped piece of the damper housing, enough to easily fit the flex liner through it. If the
opening is wide enough, the break out is not necessary.
8. Install Insert only in chimney heights of 12' (minimum) to 35' (maximum) -- as measured in step 9 below.
9. Measure the chimney height from the top of the chimney (or the existing flue liner) to a point 24"
(610 mm) above the floor of the fireplace hearth. It may be necessary to drop a rope and measure
the rope itself. Be sure to allow for all offsets in existing chimney. Cut the 4" and 3”diameter flex
liner (s) to this measured length.
5
FLUE VENTING
10. The FV-44i Insert must be vented vertically to the outside and must use the Mendota Co-Linear flexible
ducting system.

11.
(See FIGURE BELOW) The vent kits include a trimable flashing. Measure, trim and shape flashing to fit the existing flue liner. This flashing prevents water and small animals from entering area between the chimney liner and flue liner. Plan for 1” to 1-1/2” (25 mm to 38 mm) overlap on each side.
Center the flashing and mark it about 3" (75 mm) larger in each dimension than the existing chimney.
Trim the notch with snips and bend edges with hand seaming tool, metal break or pliers. Apply high
temperature silicone sealer or millpack to the male ring before slipping cap onto male ring. Attach cap
to flashing adapter ring with three self tapping screws.
Apply high temp silicone
or millpack bead.
Chimney Flashing and cap
12. Attach a sheet metal strap loop to the flex end of the liner(s) and tie a rope to it. Two installers should proceed to the roof and drop the rope (with weight on the end to make sure it goes all
the way down) and insert the liner(s) past the flexible portion, into the existing chimney – SEE
BELOW:
NOTE: Repeat this step for second liner.

NOTE: AGA APPROVED FLEX LINES ARE APPROVED FOR USE WITH MENDOTA INSERTS.
19.
Carefully slide the Insert into place in the fireplace opening. At this time, check that Insert is level and plumb with the fireplace opening and positioned in the middle of the opening. If Insert is
unsteady or needs leveling, the unit may need to be “shimmed with washers under the bottom
corners of insert.
22. The proper Insert Faceplate can now be placed in position. Assemble surround by following instructions supplied with faceplate kit. Select the appropriate size of faceplate to cover
the area between the Insert and existing fireplace opening.
...IMPORTANT...
NOTE: INSTALLATION, SERVICING AND REPAIR MUST BE DONE BY A QUALIFIED SERVICE PERSON. THE
INSERT SHOULD BE INSPECTED AT LEAST ANNUALLY BY A PROFESSIONAL SERVICE PERSON. MORE
FREQUENT CLEANING MAY BE REQUIRED DUE TO EXCESSIVE LINT FROM CARPETING, BEDDING
MATERIAL, ETC. IT IS IMPERATIVE THAT THE CONTROL COMPARTMENT BURNERS AND CIRCULATING
AIR PASSAGEWAYS OF THE INSERT BE KEPT CLEAN.
9
RAISED HEARTH SPECIFICATIONS
BOTTOM EDGE OF
GLASS WINDOW
In most installations, a 16" non-combustible protector is required in front of the unit’s glass
door surface on the floor or raised hearth. This protection can be any non-combustible
material such as 24-gauge sheet metal, tile, brick, concrete board, etc. Please note that
the required 16” clearance starts at the front face of the glass door. If replacing a woodburning insert with this gas insert, the existing and approved hearth protection will provide
adequate floor protection.
If a raised hearth extends less than 16", refer to the diagram above and the following procedure to see if additional floor protection is required.
Project a line (using string or a tape measure) from the lower edge of the glass window to
the edge of the raised hearth, continuing on to the floor. If the point of intersection with
the floor is beyond 16" from the Insert, then no further floor protection is required. If the
intersection is less than 16" from the Insert then additional non-combustible floor protection is required to meet the minimum 16".
For installations where the fireplace is raised 16" or more above the floor, or if the existing
floor is non-combustible (stone, brick, etc.), a non-combustible protector is not required.
10
GAS SUPPLY REQUIREMENTS
NOTE: IF INSERT IS OPERATED ON LP GAS, SEE PAGE 26 BEFORE PROCEDING.
CORRECT GAS PRESSURE AND PROPER GAS SUPPLY LINE SIZING IS IMPERATIVE TO THE SUCCESSFUL PERFORMANCE OF YOUR ENDOTA
GAS FIREPLACE INSERT. BE SURE THE GAS SUPPLIER OR PLUMBER CAREFULLY CHECKS FOR CORRECT GAS PRESSURE AND GAS LINE
SIZING WHEN INSTALLING THE FIREPLACE INSERT.
IT IS CRITICAL TO CAREFULLY CHECK FOR GAS LEAKS WHEN HOOKING UP THE FIREPLACE INSERT -- CHECK WITH SOAP & WATER
SOLUTION.
BE SURE TO INSTALL FLEX GAS LINE WITH BRASS-TO-BRASS FITTINGS TO PREVENT GAS LEAKS AT CONNECTIONS.
GAS SUPPLY PIPING MUST INCLUDE A DRIP LEG TO ELIMINATE THE POSSIBILITY OF CONTAMINANTS ENTERING THE GAS TRAIN. ADHERE
STRICTLY TO LOCAL AND NATIONAL CODES.
GAS SUPPLY LINE SIZING
The Mendota Gas Insert comes equipped with a 3/8" N.P.T. [1.0 cm] inlet on the main gas valve. Gas
supply piping may enter the cabinet from either the left or right side.
The proper gas line diameter must be selected to run from the supply regulator to the Insert. Refer to

GAS PRESSURE CHECKING REQUIREMENTS
A pressure tap for checking gas pressure is located on the main gas valve. A qualified installer should use this
fitting for setting the correct gas pressure during initial installation. [See Gas Pressure Chart Pg. 12].
If supply gas pressures exceed 1/2 PSIG [3.5KPA], the appliance must be isolated from its supply with an approved manual shut-off cock. This manual shut-off cock must be closed during any supply line pressure testing.
Check with your gas supplier or plumber.
.
11
If the factory-built fireplace has no gas access hole(s) provided, and access hole 1.5” or
less may be drilled through the lower sides or bottom of the firebox in a proper workmanship like manner. This access hole must be plugged with non-combustible insulation after the gas supply line has been installed.
GAS PRESSURE REQUIREMENTS
A MAJOR CAUSE OF OPERATING PROBLEMS WITH GAS APPLIANCES CAN BE IMPROPER GAS
PRESSURE!
Such problems as changes in flame color or configuration, gas pilot or burner outages, intermittent operation, changes in heat output, excessive burner noise, etc. are nearly always the result of changes in
gas pressure or improper gas pressure at the time of the installation. The most important item to
check during the installation and the first thing to check when problems occur is gas pressure!
Gas supplies normally enter a residence at 1/2 PSI (13" - 15" W.C.) (3. KPA). A regulator is then
placed inside the residence, which drops this pressure to 7" W.C. (1.8 KPA) (Nat. Gas). This "inches to
inches" regulator is of adequate capacity to service the gas appliances (such as dryer, furnace, etc.). If
this regulator's capacity is not sufficient to add the Gas Fireplace, an additional "inches to inches" regulator must be installed for the Fireplace. EXCEPTION: Some codes allow 2-PSI (1.4KPA) supplies to enter the residence, in which case "pounds to inches" regulators are used.
The following table provides information on correct gas pressure requirements. Be sure your gas supplier or plumber carefully follows this table.

Once the conversion to LPG and all the above steps have been completed, light the main burners.
Turn Gas Dial counterclockwise to “ON” then set Thermostat or push Main Burner ON/OFF switch to turn on
burners. Main burner should now light IMMEDIATELY and flame should not “lift” off burner. If there is any delay
in ignition or if flame is “lifting off” burner, turn off burner and carefully check for proper installation of logs/coals,
vent system and proper pilot flame impingement on burner and thermopile. Logs or coals must not block pilot
flame or main burner flame. Vent system must be leak proof.
ATTACHING LPG CONVERSION LABELS AND HIGH ALTITUDE DE-RATION LABEL
Two printed informational labels are included with the LPG Conversion Kit. Attach these two labels to inner surface of the left side controls access door. If you are de-rating this appliance at a high altitude, also attach the
High Altitude De-ration Label, supplied in the Owner’s Manual Packet, to this same surface.
Prior to attaching the labels, fill in all the information that is requested in these labels.
For LP installations from 610-1370 meters (2000-4500 ft.) the orifice sizes (DMS) for natural
gas are #47 Front/#39 rear and for propane gas are #57 front/#54 rear.
GAS LEAK TEST REQUIREMENT: It is the responsibility of the installer/service person to
assure that each and every gas connection and supply tubing that are a part of this fireplace
are leak proof. The qualified/ certified individual connecting the gas supply line, performing
pressure tests or performing any service to this fireplace is required to perform a THOROUGH
LEAK TEST on ALL gas fittings that are a part of this appliance or the gas supply line connection using soap-water solution or a calibrated combustible gas detector. Failure to perform
this leak test may lead to a house fire and/or an explosion. Mendota is not responsible for any
damages due to an Installer’s failure to conduct a leak test and verify that all connections and
supply lines are leak proof.
WARNING: Do not operate appliances with glass front removed, cracked, or broken.
Replacement of glass should be done a licensed or qualified service person.
Note: Consult the local or national installation code(s) to assure that adequate combustion and ventilation air is available.
30
BLOWER OPERATION AND WIRING
The Mendota Gas Inserts are equipped with hot air dual blowers. A 120-volt electrical service
must be supplied for these blowers at the fireplace at the time of installation.
These specially designed Blower Kits are equipped with heavy duty 1,000° wiring. They include an automatic snap switch that automatically turns the blowers "On" after heat up (approx. 20 min.) and "Off" after the unit cools (approx. ½ hr.). A variable speed rheostat is also
included that allows the operator to fully adjust the blower hot air output.
The low profile centrifugal, radial flow blowers are made of special alloy steel for constant
high-speed operation at high temperatures. Blowers are equipped with long-life, maintenancefree bearings that insure quiet operation and maximum airflow.
The blowers are ideal for owners who wish to maximize the heating capacity and efficiency of
Mendota Gas Fireplaces. The blowers greatly increase total heating capacity by forcefully
moving hot air away from the fireplace and mantel area and out into the room. The blowers
increase the overall efficiency of the Mendota units by up to 5%.

CUSTOMER INFORMATION AND TROUBLE-SHOOTING
MAXIMUM ALLOWABLE SURFACE TEMPERATURE
Mendota Inserts/Fireplaces comply with UL Standards for maximum surface temperatures on
exposed combustible surfaces adjacent to the Insert. 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 Insert can have a surface
temperature as high as 187° F. – 200° F. (too hot to touch).
OVER FIRING/UNDER FIRING OF BURNER
NEVER "over fire" units by adjusting gas pressure to increase BTUH above nameplate specifications. Over firing can cause permanent damage to firebox and deterioration of parts and
void warranty.
NEVER "reduce" main burner or pilot flames below required Millivolts (see pg.34)
PILOT OUTAGE AND RE-LIGHTING
If pilot goes out, be sure to wait a minimum of five minutes before attempting to re-light the
pilot. BE SURE TO ALWAYS REMOVE GLASS 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. NEVER USE ABRASIVE CLEANERS, NEVER
CLEAN GLASS WHILE OPERATING, OR WHEN GLASS IS HOT.
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, See your dealer for availability).
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 is caused by improper installation or operation. At the first sign of "sooting" (usually a
thin black film on the Fireplace viewing glass) 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.
AGA/ANSI APPROVAL
Gas appliances must be tested and certified by a nationally recognized testing and certification
laboratory to ANSI [American National Standards Institute] gas appliance safety standards.
The Mendota Gas Fireplace Insert has been tested and certified by Intertek Testing Services,
8431 Murphy Drive, Middleton, Wisconsin 53562.
The Mendota Gas Fireplace Inserts have met all necessary AGA/ANSI Standards and are fully
certified for installation in any community.

TROUBLE SHOOTING MENDOTA GAS FIREPLACE INSERT
SYMPTOM
PROBABLE CAUSES
CORRECTIVE ACTION
1. Thin black coating [soot]
forms on viewing glass.
A. Incorrect gas pressure
Have gas supplier check for correct gas pressure [7"
W.C. Nat. Gas; 11" W.C. LP Gas].
If sooting continues open-air shutter on burner [see
"Gas Flame Adjustment" below]. If sooting still continues, call a Mendota dealer.
NOTE: To clean glass - remove glass and wipe glass
with cloth or paper towel.
B. Not enough combustion air
2. Humming or whistling
coming from Fireplace Insert.
A. Normal operating noise.
Some noise is normal. It is caused by the gas supply
flowing through the gas orifice. It is expected from
any gas fireplace. The noise can be reduced by turning the Hi/Lo Knob on the control. Turning down the
flame will reduce the heat output of the Insert.
3. A change in flame appearance or burner operation.
A. A change in gas pressure.
Have your gas supplier check for correct gas 7" W.C.
Nat. Gas; 11" W.C. LP Gas]. If flame still needs adjustment see "Flame Adjustment" below.
Clean out carbon, spider webs, lint, etc. from shutter
area.
NEVER BLOCK AIR INTAKE OR OUTLET VENTS.
B. Carbon dirt or lint.
GAS FLAME ADJUSTMENT
During the initial installation, the air shutter opening should be checked to be certain that the shutter is
set correctly at 1/8" to 1/4" open for natural gas and 1/2" minimum open for L.P. gas. NOTE: For altitudes above 5,000 ft., some variations may be required.
Be sure burner and logs are properly installed (see pages 15-27). After burner has been properly installed and operated for 2-3 hours, small additional adjustments to the air shutter may be necessary for
final flame appearance. These small shutter adjustments can be made by the following procedure:
[NOTE: Very small changes in shutter settings make major changes in flame appearance.]
1. Air shutter controls are located on the right side of the unit, behind facings or door, next to the
glass door frame.
2. If flame is too "blue," push air shutter knob in (close) in small 1/8" increments until flame turns
desired realistic "orange."
3. If flame is too "orange" or is causing sooting on viewing glass, pull air shutter knob out (open) in approx.
1/8" increments until sooting stops. IF SOOTING DOES NOT STOP, TURN OFF UNIT AND CALL YOUR
MENDOTA SERVICE PERSON.
IMPORTANT: Try each new shutter setting approx. ½ hr. before making additional changes. NOTE: Changes
in front burner flame can be made by re-arranging the coals and front burner air shutter opening. (See above.)
33
MAINTENANCE
1. ANNUAL MAINTENANCE OF MENDOTA UNITS IS REQUIRED. The following procedures
must be performed each year by a Mendota approved service person. NOTE: Any adjustments to
burner, pilot or logs must be done by a qualified Mendota service person.
A. Clean all lint and dust build-up around the control. Inspect the condition of any wiring under
the burner for melting or damage.
B. Remove logs & coals and clean away any foreign matter (lint, carbon, etc.) on the burner and
logs. Be sure the burner ports are "open". Clean the pilot and under side of the logs for any
carbon deposits. NOTE: Logs should be visually checked for carbon "build-up:. If carbon deposits are visible on logs, unit should be turned off and Mendota service person contacted.
C. Make sure hot air outlet grills are free from lint and other obstructions. Never block or obstruct
grill openings. Check condition of gaskets, gaskets must be tight, replace if necessary.
