INSTALLATION INSTRUCTIONS
CAUTION: Each installat ion must conform to all local, s tate and national codes. Refer to the national fuel gas code and local zoning and code auth or ities 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 firep lace. Be sure there is 12" minimum distance from top of upper grill to bottom of mantel; see Specifications (Pg.6 & 5), and a 16" minimum noncombustible hearth extension in front of the glass surface if a raised hearth is not supplied. (See pg. 11
for "Raised Hearth").
2. Remove any additional framework or other obstructions in the exist i ng fireplace op ening and bur ning 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 contracto r r un gas line to the existing firepl a ce. Be sure gas
plumbing instructions [see Pg. 12 & 13are carefully followed. Gas supply may enter fireplace on either
side or back of fireplace, whichever is most convenient and accessible. Electrical s er vice (120 volt) should
also be supplied.
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 damper must be re-
moved or permanently welded in the "open" position.
6. If damper opening is too small for the 4" & 3" fl ue liners, it will be necessary t o 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 t he 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" diameter flex liner (s) to this measured
length.

FLUE VENTING
NOTE: In the USA, run the 4” exhaust
The FV-44i Insert must be vented vertically to the outside and must use the Mendota Co-Linear flexible ducting system.
Note: In the USA, run only the 4” exha ust liner to the Vertical V en t Cap. In the USA, run the 3” air in take
past the existing chimney damper about 2 feet. Pack around the liners at the damper area to create an air
tight seal. In the USA, do not run the 3” air intake liner to the Vertical Cap.

Chimney Flashing and cap
(See FIGURE BELOW) The vent kits include a trim-able 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.
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 4” liner(s) past the flexible portion, into the existing chimney – SEE BELOW:
NOTE: The 3” liner shall be cut at about 5 feet length and only stubbed into the chimney past
the damper, from below.
13. One installer should then return to the fireplace opening and pull the rope to guide the liner(s) into place
through the smoke shelf and the damper opening to a point 22" (560 mm) above the fireplace hearth.
The person below should wear leather gloves and Safety Glasses during this process to avoid being cut
and to safeguard eyes from flying debris.
CAUTION:WHEN USING FLEX ALUMINUM LINER, USE EXTREME CAUTION WHEN STRETCHING LINER
AROUND OFFSETS SO AS NOT TO RUPTURE LINER.

with faceplate kit. Select the appropriate size of faceplate to cover the area between the Insert and existing fireplace
opening.
IMPORTANT
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.
RAISED HEARTH SPECIFICATIONS
In most installations, a 16" non-combustible protector is required in fro nt of the unit’s glass door
surface on the floor or raised heart h. This protection can be any non-combust ible material such
as 24-gauge sheet metal, tile, brick, concrete board, etc. Please note that the r equired 16” clearance starts at the front face of the glass door. If replacing a wood-burning insert with t hi s gas in-

sert, the existing and approved hearth protection will provide adequate floor protection.
If a raised heart h extends less than 16" in front of this Insert, refer to the diagram above and the
following procedure to see if additi onal floor protection is required.
For installations where t h e f ireplace is raised 6" or more above the floor of the room, or if the ex-
isting floor in front of this Insert is non-combustible (stone, brick, etc.), a non-combustible protector is not required.
GAS SUPPLY REQUIREMENTS
NOTE: IF INSERT IS TO BE OPERATED WITH LP GAS, SEE PAGE 34 BEFORE PROCEEDING.
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 rear side. A 48” X 3/8” SS Flex supply line is supplied in the Manual Packet with
this Insert.
The proper gas line diameter must be selected to run from the supply regulator to the Insert. Re fer to the following table
for proper gas pipe diameters.
Some areas allow copper tubing or galvanized pipe - check with local approval agencies and codes NEVER use plastic

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. 13].
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.
If the factory-built fireplace has no gas access hole(s) provided, an 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 noncombustible insulation after the gas supply line has been installed.
Part #85-03-00855

GAS PRESSURE REQUIREMENTS
One 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 problem s 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 resi dence, 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.

GAS LEAK TEST REQUIREMENT: It is the responsibility of the installer/service person to assure that each and
every gas connecti on and supply tubi ng that are a part of this firepla ce 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 connect ion 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 Installe r’s failure to conduct a lea k 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

LOW BATTERY POWER DETECTION
1. Transmitter Batteries: The life span of the remote control transmitter batteries depends on
various factors: quality of the batteries used, the number of ignitions of the appliance, the
number of changes to the room thermostat set point, etc. When the Transmitter batteries are
low, a Battery Icon will appear on the LCD display of the Transmitter before all battery power
is lost. When the batteries are replaced, this icon will disappear.
2. Wall Receiver Batteries: The life span of the wall receiver batteries depend on the quality of the batteries used and
how long the batteries have been installed in the wall receiver. These batteries are only utilized during power outages.
Replace these batteries every heating season even if you have not experienced any power outages. Batteries drain
slowly even when not in use. This is a normal characteristic of all batteries.
OPERATING DURING POWER OUTAGES
This electronic ignition s ystem utilizes the supplied 110V AC power when it is available for all f unctions of this system. If
the AC power is inter rupted during a power ou tage, this system utilizes t he batteries (installed in t he Wall Recei ver) as
back-up batteries. Dur ing the power outage, the ap pliance’s burners will func tion. In addition, Flame Heig ht adjustment
will be available.
This appliance is designed and tested to be operated during power outages.

Intermittent Pilot Light and Standing Pilot Light
Features
This gas fireplace Insert is equipped with an electronic ignition
System that first lights a pilot light then uses the pilot light to
ignite the main burners. The pilot light can be set in the
“Standing Pilot” mode to allow the pilot light to remain on indefinitely by toggling the “Standing Pilot Switch” to the ON position. If the “Standing Pilot Switch” is toggled to the OFF
position, the pilot light will only light and remain ON while the
main fireplace burners are operating.
NOTE: Before inserting batteries into the Remote Receiver’s battery
compartment, toggle the Pilot Light ON/O FF switch to the OFF
position. Toggle the switch “DOW N ” to OFF. If the Pilot Light
ON/OFF switch is left in the ON position, the pilot light will start
sparking as soon as the batteries are inserted and the system may
“Lock-Out” if the ga s line is turned to off.
IPI Mode: This mode turns the pilot light “OFF” when the fire-
place is not functioning and only lights the pilot light automatically
when a call for heat is made by the remote control.
Standing Pilot Mode: If the “Standing Pilot Switch” is to ggled
to ON, the pilot light will ignite and r emain ON as long as the
“Standing Pilot Light Switch” is in the ON position.
NOTE: Mendota Fireplaces recommends that the Standing Pilot Mode be used during the winter months when
external temperatures fall below 50
fireplace chimney heated for proper updraft during burner ignition and it will also eliminate excessive condensation of exhaust vapors on the door glass. Further, leaving the fireplace
in the Standing Pilot Mode will keep the fireplace body warm and eliminate cold drafts and heat loss to the cold air that is
trapped inside the firebox.

CUSTOMER INFORMATION AND TROUBLE-SHOOTING
SYMPTOM
PROBABLE CAUSES
CORRECTIVE ACTION
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.
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.
CLEANING VIEWING GLASS
The viewing glass should be cleaned periodically. Exterior glass may be cleaned with cleaner as desired. For 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” (# 65-0600455, 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 immedia tely 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 responsib le 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
1. Thin black coating
[soot] forms on viewing
glass.
2. Humming or whistling
coming from Fireplace
Insert.
3. A change in flame appearance or burner operation.
A. Incorrect gas pressure
B. Not enough combustion
air
A. Normal operating noise.
A. A change in gas pressure.
B. Carbon dirt or lint.
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.
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 hea t output of the Insert.
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.

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 17
-27). After burner has been properly installed and
operated for 2-3 hours, small additional adjustments to the air s hutter may be necessary fo r 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 contro l s are located on the right side of the unit, behind facings or door, next to the glass door
frame.
2. If flame is to o "blue," push air shutter k nob 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" incre-
ments 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 b urner air shutter opening. (See above. )
NOTICE: Initial heater start-up will cause some NON TOXIC “off gassing” of adhesives, gasket binders, paint and other
materials. Most nuisance odors will be eliminated after the first two hours of operation; however, slight amounts may be
present during first 24 hours of initial operation. To eliminate all nuisance odors, continuously operate this wall unit on the
HIGH setting for 4 to 6 hours.
WARNING: Label all wires prior to disconn ection when servicing controls. Wiring errors can cause improper
and dangerous operation. Verify proper operation after servicing.
