LOCATING THE FIREPLACE AND 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.
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 250 on mill volt 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 leak proof.
The Mendota Direct Vent Fireplace may be placed within inches of adjacent sidewalls. (See FIGURE 1 on pg. 8). 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 as per FIGURE 1 on pg. 4. Non-combustible
(marble, brick, stone, etc.) 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 APPROVED VENT
SYSTEMS AND MENDOTA APPROVED VENT CAPS. SEE PAGEA 8-15 FOR SPECIFIC VENTING INFORMATION.
KEEP ELECTRONIC APPLIANCES AWAY: DUE TO THE HIGH TEMPERATURES IN THE VICINITY OF THIS
FIREPLACE, MENDOTA RECOMMENDS THAT ALL ELECTRONIC APPLIANCES INCLUDING AUDIO/VIDEO
APPLIANCES AND THEIR RECORDING MEDIA (ie. TV, VCR, DVD PLAYER, CD PLAYER, TUNERS, TELEPHONES,
CASSETTE TAPES, VIDEO TAPES, CDs, DVD CDs) BE KEPT WELL AWAY FROM THIS FIREPLACE.
VENTING REQUIREMENTS:
Use only Mendota specified vents and vent caps when installing your fireplace. Closely follow venting locations, directions
and requirements (see pages 10-17). Observe the restrictions relating to vent position on exterior of home (see pg. 10).

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 down to 22,500 BTUH by slowly turning the Hi/Lo temperature knob on the gas valve counter
clockwise from "Hi" to "Lo". Further reduction of heat output, down to 7,500 BTUH, can be achieved by turning off the rear
burner using the switch provided behind the lower grill. The 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.
HEARTH PROTECTION REQUIREMENTS: A non-combustible hearth protector is required and must extend a minimum
of 14" in front of the fireplace (see Figure 1 on pg. 4 for raised hearths). We suggest installing the Mendota Fireplace 6 to
12 inches above the floor by utilizing an elevated hearth.
CAUTION: If you intend to install either the Andover Door Front or the Prairie Door Front on this fireplace, make certain
that the top surface of the hearth protector is flush with the bottom surface of the fireplace, no higher. Failure to follow this
guideline will prevent proper mounting and function of these two Fronts. See Page 16 for specific details.
ELECTRICAL REQUIREMENTS:
A blower kit is supplied as standard equipment on your Mendota Direct Vent Fireplace; A 120 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 a switch or variable control in power supplied to fireplace. Connect this 120 VAC supply line
to e left side. CONNECT 120 VAC TO ONLY THE JUNCTION BOX INSTALLED ON THE LEFT SIDE OF THIS
APPLIANCE.
The blower kit in 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 remote control transmitter. 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 .
Wall Thermostats are NOT recommended for this appliance. A Thermostatic Remote Transmitter is supplied with this
appliance. Consult your dealer or the Mendota Service Department if you wish otherwise.

local zoning and code authorities for details on installation requirements. The Mendota Fireplace 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 to the most current edition of the National Fuel Gas Code ANSI Z223.1, also known as NFPA 54. NOTE:
The Mendota DXV Fireplace is approved for mobile home and bedroom installations.
CAUTION: The Mendota DXV Fireplace may be installed in a manufactured (mobile) homes after the first sale of the
home. Manufactured home (mobile home) installation must conform with the Manufactured Home Construction and Safety Standard, Title 24 CFR, Part 3280, or, when such a standard is not applicable, the Standard for Manufactured Home
Installations, ANSI A225.1/NFPA 501A, or CSA Z240.4-Gas Equipped Mobile Housing. Consult your local building official.
Note: For mobile home installations unit must be bolted to the floor and properly grounded.
1. After selection of the desired fireplace location, prepare the rough opening using framing dimensions on page 4.
Prepare opening to allow for co-axial vent (see "Flue Venting Instructions" on pgs. 13-21).
2. Check to make certain all venting requirements and locations are being followed. (See pg 13 -21).
3. The Fireplace is designed to be installed into rough framing. The drywall will cover the adjustable nailing flanges
on the Fireplace sides. Before sliding the Fireplace into the framed opening, adjust the nailing flanges to accommodate the thickness of the wall material. NOTE: FRAMING MATERIAL ABOVE FIREPLACE MUST MAINTAIN
CORRECT CLEARANCES TO VENT PIPE.
4. Slide Fireplace into the rough framed opening. When finishing the unit, combustible materials may
overlay nailing flanges and come in contact with the side edges of the black front surface, but may
not overlay the 2" black surface. A 40-1/8” x 4” Top Screw Strip (part #HA-41-00015) is supplied with
the fireplace and must be installed on the top of this fireplace. The Top Screw Strip provides a 4”
clearance to combustible materials at the top of the fireplace. See Page 8 for specific details.
5. Combustible wall covering materials may only be installed down to the top flat edge of the Top Screw
Strip. Noncombustible boards such as “Dura-Rock” or “wonder board” can be installed on top of the
face of the Top Screw Strip and on top of the rest of the black face of the fireplace. Noncombustible
material, such as marble or brick, can be installed over the 2" black surface up to the inside edges of
black frame only if some Designer Fronts are to be installed. See Page 23 for specific details and
exceptions. Rough framing can come no closer to unit than the stand-offs.
6. Level the Fireplace and secure into opening by nailing through the nailing flanges on cabinet side
panels. Holes are provided in fireplace floor behind grill to lag screw fireplace to floor, if required.
NOTE:
A removable panel in the enclosure for future visual inspection of the flue connection is
recommended
7. Have an electrician install a 120 Volt supply to the junction box on lower left side of the fireplace cabinet. Connect
wires to the duplex outlet. This duplex outlet is removable from outside of cabinet for easy wiring. Make sure the
outlet is properly grounded and that the installation conforms to all local and national wiring codes. See "Blower
Operation" below, Blower Wiring Diagram and "Electrical Requirements".
8. Have gas supplier or qualified plumber install gas supply line to fireplace and connect to gas nipple.
Be sure gas and plumbing instructions and all local and national codes are carefully followed. Carefully check for gas leaks and for proper gas pressure.
IMPORTANT: Any safety screen, guard, glass, grill, pressure relief cap, etc. removed for servicing a fireplace/room
heater must be replaced prior to operating the fireplace/room heater.
BLOWER OPERATION
The Mendota DXV Fireplace is designed so the blower operates continually when main burner is on. The blower output
can be regulated with the Remote Control Transmitter but the blowers cannot be turned off when this fireplace is hot.
NOTE: There will be a time delay in blower operation during "heat-up" (approx. 10 min.) and extended blower operation
during "cool-down" of unit. (Approx. 1/2 hour).
OPERATION DURING POWER OUTAGES: This fireplace is designed to operate for a maximum 1-1/2 continuous
hours during power outages on HIGH FIRE. The blower will not operate, but natural convection can be improved by removing the upper Millennia grills, opening the Andover and Prairie Doors and opening the Wellington Screens. If burned
on LOW FIRE (front burner only), this appliance may be run continuously indefinitely during power outages.

GAS SUPPLY REQUIREMENTS
Correct gas pressure and proper gas supply line sizing is imperative to the successful performance of your Mendota gas
fireplace. Be sure the gas supplier or plumber carefully checks for correct gas pressure and gas line sizing when installing
the fireplace.
It is critical to carefully check for gas leaks when hooking up the fireplace -- check with soap & water solution.
Be sure to install "approved" 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 for entire installation.
GAS SUPPLY LINE SIZING
The Mendota Gas Fireplace comes equipped with a 12” flexible connector kit including a manual shutoff ball valve. Gas
supply piping must enter the Fireplace cabinet from the right side.
The included manual shut-off valve meets Federal Codes. I required by local codes, install an additional manual shutoff
valve upstream of the fireplace’s manual shutoff valve. The appliance and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of ½ PSIG
(3.5 kPa).
The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during
any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 PSIG (3.5 kPa).
A proper gas line diameter must be selected to run from the supply regulator to the Fireplace. Refer to the following table
for proper gas pipe diameters. Strictly adhere to the correct pipe sizes. If in doubt, use the next larger size.

GAS PRESSURE CHECKING REQUIREMENTS
Inlet and manifold gas pressure checking taps are located on gas valve (see Figure 2 on Page 10). A qualified installer
should use these fittings for setting the correct gas pressure during initial installation.
NOTE: DO NOT DAMAGE OR KINK THE FLEX CONNECTOR. CHECK FOR GAS LEAKS WITH SOAP AND WATER
SOLUTION.
NOTE: 3/8" FLEX OR RIGID PIPING MAY BE USED TO CONNECT GAS SUPPLY TO UNIT DEPENDING ON STATE
AND LOCAL CODES.
NOTE: BE SURE TO INSTALL FLEX GAS HOSE WITH BRASS-TO-BRASS FITTINGS TO PREVENT LEAKS AT
CONNECTION.
NOTE: THE HARD PLUMBING FITTING PROVIDED IS TO BE USED WITH INSTALLATIONS REQUIRING HARD
PLUMBING. IT MAY BE REMOVED IF THE FIREPLACE IS BEING INSTALLED WITH A FLEXIBLE
CONNECTOR.
11
GAS PRESSURE REQUIREMENTS
A MAJOR CAUSE OF OPERATING PROBLEMS WITH GAS APPLIANCES CAN BE IMPROPER GAS PRESSURE!
Problems such as changes in flame color or flame height, 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.

FLUE VENTING INSTRUCTIONS
The Mendota Fireplace must be vented using DuraVent or Amerivent or Security venting system. All warranties will be
voided and serious fire, health or other safety hazards may result from any of the following actions: Installation by unauthorized personnel; Installation of any damaged component; unauthorized modification of vent system; installation of any
components not manufactured or approved by security chimney Simpson DuraVent, Amerivent and Mendota; failure to
meet all clearance requirements; failure to properly twist-lock all components.
Consult local building codes before beginning the installation.
HIGH ALTITUDE INSTALLATION INFORMATION: Prior to installing at altitudes higher than 7500, please contact the Mendota technical service department for specific venting requirements and venting restrictions.
WARNING
Always maintain required clearances (air spaces) to combustibles to prevent a fire hazard. Do not fill air spaces with insulation. Check installation instructions for minimum clearance requirements between the outer walls of the vent pipe and
nearby combustible surfaces. Be sure to check the vent termination clearance requirements from decks, windows, soffits,
gas regulators, air supply inlets, and public walkways, as specified in these installation instructions and local building
codes. SAFETY PRECAUTIONS FOR THE INSTALLER: 1) Wear gloves and safety glasses for protection; 2) Exercise
extreme caution when using ladders or on roof tops; and 3) Be aware of electrical wiring locations in walls and ceilings.
The gas appliance and vent system must be vented directly to the outside of the building, and never attached to a chimney
serving separate solid fuel or gas burner appliance. Each direct vent gas appliance must have its own separate vent system. Common vent systems are prohibited.
To assure proper venting performance of the high-performance Mendota Direct Vent Fireplaces and Stoves, it is critical
that the DuraVent GS vent pipe sections are sealed tightly and leak-proof. This means that all pipe sections must be carefully rotated into the fully "twist-locked" position (Dura Vent only).
WE STRONGLY RECOMMEND THAT FIXED LENGTH PIPE SECTIONS BE USED IN PLACE OF TELESCOPING
SECTIONS WHENEVER POSSIBLE
Note: When using Dura-vent DV pipe you must use a silicate stove masonry sealant [Millpak Sealant #65-06-00909] on all
inner pipe joints. On the exterior (air intake) pipe joints, high temperature foil tape may be used instead of the masonry
sealant. Contact your dealer to obtain this sealant material.
DO NOT SEPARATE TELESCOPING SECTIONS. THEY MUST BE USED AS COMPLETE ASSEMBLIES.
COMPONENT "TWIST-LOCK" CONNECTION PROCEDURE
DuraVent, Amerivent and Security brand pipe and fittings are designed with special
twist-lock connections. Twist-lock procedure is as follows: four (4) indentations, located on the female ends of pipes and fittings are designed to slide straight in to the
male ends of the adjacent pipes and fittings, by orienting the four pipe identifications
so that they match and slide into the four entry slots on the male ends (FIGURE 4).
FIGURE 4: Twist-Lock Piping
Push the pipe sections completely together then twist-lock one section clockwise,
approximately 1/4 turn until the two sections are fully locked. The female locking
lugs will not be visible from the outside on the black pipe or fittings.

FIREPLACE.
IMPORTANT: REFER TO DRAWINGS ON PAGE 12-14 WHILE FOLLOWING THESE INSTRUCTIONS.
o
The horizontal distance from flue outlet center to outside wall must not exceed 24" if a 90 elbow is connected directly to
flue outlet. ALWAYS MAINTAIN 1" CLEARANCES FROM VENT PIPE TO COMBUSTIBLES, 2" ABOVE PIPE ON
HORIZONTAL RUNS. Use "fixed" pipe sections in place of adjustable pipe sections wherever possible. If adjustable pipe
sections must be used, 1000º Millpak sealant (#65-06-00909) must be used on the inner pipe joints (DuraVent Only). Do
not fill air spaces within the required clearance distances (1” around vertical pipe sections and 2” above horizontal pipes
and fittings) with insulation or other material.
Position fireplace in desired location. See pg.12 for guidelines on proper vent cap placement on the exterior of home.
Check to determine if wall studs are in the way when venting system is attached. If this is the case, you may want to adjust the fireplace location.
Measure from the top of the fireplace up minimum 7 1/2" to centerline of 90º elbow. (pg. 8) and mark wall directly at the
center of where the vent pipe will penetrate the wall.
Cut and frame a 10-3/4" x 10-3/4" opening in the outside wall. The hole must be positioned so the vent system will run
level or have a ¼ " rise AND be perpendicular to the wall. The height of the opening must be located to meet all local and
national building codes and not allow the termination to be easily blocked or obstructed. If wall being penetrated is noncombustible material, i.e. masonry block, brick, etc., an 8 ½" diameter hole is acceptable. A Wall Thimble (#45-01-00229)
must be used when penetrating a combustible wall.
Make sure that all component connections are in their fully twist-locked position and are leak-proof. Make sure that 1000º
Millpak sealant (#65-06-00909) is used on the inner pipe joints of all pipe sections (Dura Vent only).
*NOTE: DO NOT SEPARATE TELESCOPING SECTIONS. USE AS COMPLETE ASSEMBLIES.
The length of the horizontal piece that fits through the wall will be determined by the thickness of the wall. When installed,
the end of the horizontal piece must be flush with the exterior wall of the home. There MUST be a minimum of 1" air
space clearance to combustibles from all vent pieces (2" above horizontal runs).
From the exterior of the home, slide the horizontal vent cap over the end of the horizontal pipe and tightly secure the cap to
the wall with screws. Seal with a high quality caulking.
NOTE: The Horizontal Vent Cap should not be recessed into the wall or siding.
18
A-2
ELEVATED RISE THROUGH-THE-WALL VENTING FOR NG AND LPG
The minimum vertical rise from top of fireplace is 48 in. when used with the maximum horizontal run of 16 ft. For other
venting configurations within these maximum limits see pg. 15.
NOTE: All horizontal runs of vent pipes must have a ¼" rise for every 1' of run toward the termination. Never allow the
vent to run downward. This will cause high temperatures and the possibility of a fire.
USING OFFSETS AND RETURNS:
A single 90º vertical-to-horizontal elbow is already calculated into the
allowable maximum 16' horizontal run. Each additional 90º elbow reduces the maximum horizontal distance by 3'. A maxo
o
imum of two 90° or four 45° elbows, in addition to the first 90 elbow, can be used (total equivalent of three (3) 90 elbows
in entire vent system. 45º elbows reduce the maximum horizontal distance by 1½ '.
SUPPORT: Horizontal runs of pipe will require one vent support for every 3 ft. of pipe.
CAUTION: Be sure to maintain 1" air space clearances to any combustibles around all pipe sections that are vertical. Be
sure to maintain 1” air space clearances to any combustibles on the sides and below all horizontal pipe sections and elbows and 2" from the top of all horizontal pipes and fittings.
IMPORTANT: REFER TO DRAWINGS ON PAGE 15 & 16 WHILE FOLLOWING THESE INSTRUCTIONS.
Position fireplace in desired location. See pg. Error! Bookmark not defined. For guidelines on proper vent cap placement on exterior of home. Check to determine if wall studs are in the way when vent system is attached. If this is the case
you may need to adjust the fireplace location.
Locate position where vent pipe will pass through any ceilings and will penetrate the outside wall. Since vent pipe sections
"overlap" we suggest pre-assembling and measuring the total vent pipe run so you can more accurately locate the point
where the vent pipe will penetrate the outside wall. Be sure all vent components are properly twist locked and leak-proof.
Be sure 1000º silicate sealant (Millpak #65-06-00909) is used in the inner joints of all pipe sections (Dura Vent only).
*NOTE: DO NOT SEPARATE TELESCOPING SECTIONS USE AS COMPLETE ASSEMBLIES.
Cut and frame a 10-3/4" x 10-3/4" opening in the outside wall and in any ceiling openings. The outside wall hole must be
positioned so the vent system will have a ¼ " rise per foot of run AND be perpendicular to the wall. The height of the opening must be located to meet all local and national building codes and not allow the termination to be easily blocked or obstructed. A ceiling fire stop spacer is required at any floor (ceiling) opening.
Connect a 90° elbow to the fireplace adapter on top of fireplace vent outlet.
Always use a Wall Thimble (#45-01-00229) when penetrating a combustible wall.
The horizontal pipe must end flush with the exterior wall of the home. Horizontal pipe will require a proper support (part
#45-01-00234) every 3 ft. of vent pipe. THERE MUST BE A MINIMUM OF 1" CLEARANCE TO COMBUSTIBLES FROM
ALL VENT PIECES (2" above horizontal runs). From the exterior of the home, slide the horizontal vent cap over the end of
the horizontal pipe and tightly secure the vent cap to the wall with screws. Seal with high quality caulking.
NOTE: Venting terminal should not be recessed into the wall or siding.
19
B - 1 VERTICAL THROUGH-THE-ROOF VENTING FOR NG AND LPG
The maximum vertical run of vent pipe is 36 ft. from the top of the fireplace. The fireplace will support a run of a maximum
of 36 ft. Maintain 1" air space clearances on all sides of vents (2" above horizontal vents).
IMPORTANT: REFER TO DRAWING ON PAGE 10 & 11 WHILE FOLLOWING THESE INSTRUCTIONS.
Place the fireplace in its desired location. Drop a plumb bob from the ceiling to the center position of the fireplace flue exit.
Mark the location where the vent will penetrate the ceiling. Drill a small hole at this point. Next, drop a plumb bob from the
roof to the hole previously drilled in the ceiling. Mark and drill the spot where the vent will penetrate the roof. Determine if
ceiling joists, roof rafters or other framing will obstruct the venting system. You may need to relocate the fireplace or need
to offset, to avoid cutting load bearing members.
Cut and frame a 10-3/4" x 10-3/4" opening in the ceiling centered on the hole drilled in No. 1.
To determine the length of the vent pipe required, measure the distance from the fireplace flue outlet to the ceiling, the
ceiling thickness, and the vertical rise in the attic or second story and allow sufficient vent height above roofline. For two
story installations, fire stops are required at each floor level. If an offset is needed in the attic, additional pipe and elbows
will be required.
Assemble the desired lengths of vent pipe and elbows to reach from the fireplace flue outlet. Ensure that all pipe and elbow connections are in there fully twist-lock position and are leak-proof. Maintain 1" airspace clearances to combustibles
(2" above horizontal runs). Be sure 1000º silicate sealant (Millpak #65-06-00909) is used on the inner pipe joints of all
pipe sections (DuraVent Only).
If an offset is necessary, it is important to support the vent pipe every 3 ft. to avoid excessive stress on the elbows and
possible separation. Wall straps (#45-01-00231) are available for this purpose.
Whenever possible, use 45º elbows instead of 90º elbows. The 45º elbow offers less restriction to the flow of flue gases
and intake air. If a 90º elbow is necessary there must be a minimum of a one-foot pipe section rise after the 90º elbow to
the vent cap or to the next offset. A maximum of three (3) 90ºelbows are allowed per installation.
o
o
Each 90º elbow, after the first 90 elbow, reduces the maximum horizontal distance by 3'. Each 45 elbow, after the first
o
equivalent 90 elbow, reduces the maximum horizontal distance by 1-1/2’.
Cut a 12" x 12" opening in the roof, centered in the small drilled hole placed in the roof in No. 1. The opening
should be a sufficient size to meet all clearance requirements. Continue to assemble lengths of pipe and elbows necessary to reach up through the roofline. Galvanized pipe and elbows may be utilized in the attic, as
well as above the roofline. The galvanized finish is desirable above the roofline due to its higher corrosive resistance.
Slip the flashing over the pipe sections protruding through the roof. Secure the base of the flashing to the roof
with roofing nails and seal flashing to roof. Ensure the roofing material overlaps the top edge of the flashing.
Verify you have at least the minimum clearance to combustibles at the roofline.
Continue to add pipe sections until the pipe and the vent cap meet the minimum building code requirements, as outlined in
No. 8 on the following page.
For multi-story vertical installation, a ceiling fire stop is required at the second floor and any subsequent floors. The opening should be framed to 12" x 12" inside dimensions as described in step No. 5.
Any occupied areas above the first floor, including closets and storage spaces, which the vertical vent passes through,
must be enclosed. The enclosure may be framed and sheet rocked with standard construction materials, however, be
sure to maintain minimum allowable clearances between the outside of the vent pipe and the combustible surfaces of the
enclosure.

Place Log “J” as shown here. You will
find that it sits down well and “selfpositions” on the ember bed. You may
rotate the position of this log as it
suites your taste. Exact position is not
critical.
Identify Log “J”. This log is
designed to hide the pilot light
flames and also to aid in the front
ember-bed glow effect and
realism.
Place small coals between Firebox Front and front Burner. Pile the coals higher near the Front burner to build height. Any
excess coals should be spread on the far left and far right sides of firebox to extend the coal bed effect. A couple of coals
may be place behind front burner tube on Ember Bed “A” but sparsely. Avoid covering front burner tube’s gas ports.
Hold a clump of Inswool/ Rockwool in one fist tightly with a small portion protruding out. Brush
Inswool/Rockwool over top of front burner tube, over Ember Bed “A” and over entire log assembly. Brushed
Inswool deposits should be a thin layer but enough to hide the front burner tube. Brush generously over
front ember bed and all logs. Also brush lightly over center burner tube and rear burner tube. Be carefuly
when brushing on middle and rear burner tubes. Do not deposit large chunks of inswool on middle or rear
burners. Attempt to break inswool into small fibers as you brush.
31
FINAL LOG SET, COALS AND INSWOOL LAYOUT RECOMMENDED PATTERN
Note: Some minor adjustment to coals locations may me necessary on LP gas units. Also, some
adjustment to brushed inswool thickness may be necessary if inswool brushed over middle or
rear burner are too thick and heavy and impede combustion air flow to burner.
COMPLETED LOGS AND COAL BED ASSEMBLY EVALUATION
See the picture, shown above. This picture shows the recommended log positions. Slight variations
in the position of each log is allowed. However, if any log position is significantly out of position in
comparison to the diagram above and if any flames are floating off the burner surface (Ghosting) after 10 minutes of starting the fireplace, turn off the fireplace and contact your installer or fireplace
dealer. Have the Installer/Dealer adjust the log positions of the logs and coals and also conduct a
thorough evaluation of the venting configuration to make certain that the venting configuration conforms to Mendota’s venting requirements, which are listed in this Installation and Operations Manual.

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.
OPERATING DURING POWER OUTAGES
This electronic ignition system utilizes the supplied 110VAC power when it is available for all functions of this system. If the
AC power is interrupted during a power outage, plug in the battery pack (supplied with this fireplace on the right side of the
courtesy panel)..
During the power outage, the appliance’s burners will function. In addition, Flame Height adjustment and Secondary Burner ON/OFF functions will be available. The Fan and Accent Light, which are wholly dependent on 110VAC power, will not
function.
The fireplace is designed to operate during power outages for 1-1/2 continuous hours, Maximum. The blower will not operate, but natural convection can be improved by removing the upper grill and opening the screen doors (depending on the
type of optional front installed). After 1-1/2 continuous hours of operation, during the power outage, turn off the burners for
1 hour and allow the fireplace to cool down. Consecutive 1-1/2 hour burn and 1 hour cool down cycles are allowed.

Intermittent Pilot Light and Standing Pilot Light Features
This gas fireplace 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 CPI (Standing Pilot) mode to allow the pilot light to remain on indefinitely
by setting the Remote Transmitter to CPI mode. If the remote transmitter is set to the IPI (Intermittent Pilot) mode, the
pilot light will only light and remain ON while the main fireplace burners are operating.
IPI Mode: This mode turns the pilot light “OFF” when the fireplace is not functioning and only lights the pilot light automatically when a call for heat is made by the remote control.
(CPI) Standing Pilot Mode: If set to CPI Mode, the
pilot light will ignite and remain ON at all times.
Setting to IPI versus CPI mode:
With the remote transmitter OFF, press the MODE
button. You will see either “CPI” or “IPI” displayed
on the transmitter screen. Press the UP arrow button to set “CPI” mode and press the DOWN arrow
button to set “IPI” mode. One set to the desired
setting, press On/Off button to activate the fireplace.
NOTE: Mendota Fireplaces recommends that
the (CPI) Standing Pilot Mode be used during the winter months when the average daily high temperature falls
o
below 50 F. This will keep the 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.
38
Backup Batteries
Backup Batteries are to be installed in the Battery Pack located on the right side of the Courtesy Panel beneath the glass
frame. The life span of the backup batteries depends on the quality of the batteries used and how long the batteries have
been installed in the Battery Pack. With good quality batteries, you can expect proper operation for periods in excess of 2
weeks.
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. To prevent the batteries from bleeding while not in use, you may choose to remove the backup batteries and install
them only when they are needed.
OPERATING DURING POWER OUTAGES
This electronic ignition system utilizes the supplied 120VAC power when it is available for all functions of this system. If the
AC power is interrupted during a power outage, this system utilizes the batteries (installed in the Battery Pack) as back-up
batteries. During the power outage, the appliance’s burners will function. In addition, Flame Height adjustment and Secondary Burner ON/OFF functions will be available. The Fan and Accent Light, which are wholly dependent on 110VAC
power, will not function.
The fireplace is designed to operate during power outages for 1-1/2 continuous hours, Maximum. The blower will not operate, but natural convection can be improved by removing the upper grill and opening the screen doors (depending on the
type of optional front installed). After 1-1/2 continuous hours of operation, during the power outage, turn off the burners for
1 hour and allow the fireplace to cool down. Consecutive 1-1/2 hour burn and 1 hour cool down cycles are allowed.
39
BLOWER OPERATION AND WIRING
WARNING: The Electrical Junction box within this appliance must be connected to a grounded LIVE power circuit. No
switches, Light Dimmers or Fan Speed Control Devices are allowed within the same electric circuit as this appliance.
Connect only to a LIVE electrical power supply that is not controlled by any other switching device.
Dual blowers are provided as standard equipment with this DXV45 DT3 Fireplace. The dual blowers have an air output
rating of 210 CFM (in free air). This Fireplace is designed to operate with the blowers turned ON when the appliance is
running and hot. The blowers increase the overall efficiency of this fireplace and aid in distributing and circulating heat
to the room this Insert is installed in.
BLOWER BREAK-IN PERIOD: The integrated blowers in this Insert may exhibit some bearing noise and electrical static noise during the first few hours of operation. This is normal during the break-in period. It is recommended that following the Paint Curing Cycle, the blowers be run at their maximum speed for two 3-hour periods. The blowers in a few
units may take longer to break-in and may require additional operation time before all extraneous noise is eliminated.
Please allow adequate operational time (a minimum of 2 weeks) for the blowers to break-in before you contact your
dealer for service.
WARNING: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and
dangerous operation. Verify proper operation after servicing.
BLOWER OPERATION
This Fireplace is designed so the blower operates at all times the fireplace is operating. The blower output can be
regulated with the Remote Control. NOTE: There will be a time delay in blower operation during "heat-up" (approx. 10
minutes) and extended blower operation during "cool-down" of unit. (Approx. ½ hour). NOTE: Power supply to blower
must be continuous. DO NOT use a switch or variable speed control in the power supplied to fireplace.
OPERATION DURING POWER OUTAGES
The fireplace is designed to operate during power outages for 1-1/2 continuous hours, Maximum. The blower will not
operate, but natural convection can be improved by removing the upper grill and opening the screen doors (depending
on the type of optional front installed). After 1-1/2 continuous hours of operation, during the power outage, turn off the
burners for 1 hour and allow the fireplace to cool down. Consecutive 1-1/2 hour burn and 1 hour cool down cycles are
allowed on if fired on the maximum HIGH FIRE setting. If only the FRONT BURNER is fired, you may run this fireplace
indefinitely during a power outage at this LOW FIRE setting.

Clean out carbon, spider webs, lint, etc. from shutter
area.
Logs and burner.
NEVER BLOCK AIR INTAKE OR OUTLET VENTS.
B. Carbon dirt or lint.
MAIN BURNER GAS FLAME ADJUSTMENT
During initial installation the burner should be removed and verified that the air shutter opening is set correctly at 1/8" to 1/4"
open for Natural gas and 1/4” - 1/2" minimum open for L.P.
gas.
NOTE: For altitudes above 5,000 ft., some variations may be
required.
REAR BURNER
SHUTTER KNOB
Be sure burner and logs are properly installed. After burner has
been properly installed and operated for two to three 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.
Pull Out Opens,
Push in Closes.
Air shutter knob is located behind the lower grill.
If flame is too "blue" slowly push air shutter control knob in small
1/16" increments until flame turns desired realistic "orange."
If flame is too "orange" or is causing sooting on viewing glass or
on logs, pull air shutter control knob outward in 1/16" increments until sooting stops. IF SOOTING DOES NOT STOP,
TURN OFF UNIT AND CALL YOUR MENDOTA SERVICE PERSON.
The front coal bed burner is pre-set at 1/8" open. Normally, no adjustment is required. For LPG applications, a slightly
larger (greater than 1/8” opening in the front burner air shutter may be required if soot deposits on front logs or on coal
chunks).
IMPORTANT: Try each new shutter setting approx. ½ hour before making additional changes. NOTE: Changes in
front burner flame can be made by re-arranging the coals.
CAUTION: Any changes in pilot flame must be made by qualified person and checked with voltmeter.
41
CUSTOMER INFORMATION AND TROUBLE-SHOOTING
MAXIMUM ALLOWABLE SURFACE TEMPERATURES
Mendota Fireplaces comply with UL Standards for maximum surface temperatures on exposed and embedded combustible surfaces adjacent to the unit. The Maximum allowable surface temperature is 117° F. over ambient (room) temperature on exposed surfaces. Thus, if a room is 70° – 80° the exposed combustible surfaces immediately surrounding the
Fireplace can have a surface temperature as high as 187° F. – 197° F. (too hot to touch). The continuous blower operation automatically keeps temperatures within these safety limits. During Power Outages, remove upper grills on Millennia
Fronts, open doors on Andover and Prairie Fronts and remove upper grills, remove Victoria and Tuscany Upper Face.
This will increase convection air flow and prevent overheating.
OVER FIRING OF BURNER
NEVER "over fire" units by adjusting gas pressure or drilling out the orifice to increase BTUH above nameplate specifications. Over firing can cause permanent damage to firebox and deterioration of parts and void warranty.
MAINTAINING CORRECT PILOT FLAME - PILOT OUTAGE & RELIGHTING
Never lower (reduce) pilot flame length less than 1 inch long.
If pilot goes out, be sure and wait a minimum of 5 minutes before attempting to e-light the pilot flame.
CLEANING VIEWING GLASS
CAUTION: Do Not use oven cleaner to clean glass. The viewing glass should be cleaned periodically. Exterior glass may
be cleaned with cleaner as desired. Interior glass - use soap and water, Kel Kem Glass Cleaner or equivalent.
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” or comparable
product (See your dealer).
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
Sooting is caused by improper installation or improper burner air shutter operations. However, some small areas of soot
deposits on log surfaces are deemed acceptable. Open the burner air shutters if you observe sooting. If you observe large
soot areas (larger than 1”x2”) on log surfaces or signs of sooting on the door glass (usually a thin black film on the Fireplace viewing glass or on the outside of the home around the vent cap), open both burner air shutters fully. If sooting continues, the unit must be immediately turned off and the local Mendota dealer promptly informed. 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.
OPERATION DURING POWER FAILURE
The fireplace is designed to operate during power outages for 1-1/2 continuous hours, Maximum. The blower will not
operate, but natural convection can be improved by removing the upper grill and opening the screen doors (depending
on the type of optional front installed). After 1-1/2 continuous hours of operation, during the power outage, turn off the
burners for 1 hour and allow the fireplace to cool down. Consecutive 1-1/2 hour burn and 1 hour cool down cycles are
allowed on if fired on the maximum HIGH FIRE setting. If only the FRONT BURNER is fired, you may run this fireplace
indefinitely during a power outage at this LOW FIRE setting.
Hot air convection may be improved by removing upper grill of the Millennia and Deerfield Fronts, opening the doors on the
Andover and Prairie Fronts and opening the screen on the Wellington Front.
Replace these parts for operation after the unit has cooled completely and power is restored.
42
MAINTENANCE
ANNUAL MAINTENANCE OF THIS MENDOTA FIREPLACE 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. Replace backup batteries at least 2 times annually. Replace them when the Day Light Savings Time changes.
B. Clean all lint and dust build-up around the control. Inspect the condition of any wiring under the burner for
melting or damage.
C. 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. Be sure logs are re-installed per instructions.
D. Check condition of glass door gasket, gasket must seal tightly over firebox, replace if necessary.
E. Periodically check to verify that the vent system and vent cap are open and free of blockage.
F. Before re-installing glass, have qualified service person check the operation of the pilot
G. The viewing glass should be cleaned periodically. Exterior glass surface may be cleaned with cleaner as desired.
To clean Interior glass surface, use Kel Kem “polish plus" (part # 65-06-00455) or comparable product. Do not use
oven cleaner or abrasive cleaners to clean glass. Do not clean when glass is hot.
H. Periodic visual check of pilot flames and the pilot ignition spark system is required. Pilot lighting Spark must originate on Pilot Spark Rod Tip and end at Pilot Hood every time the system initiates a spark. Pilot flame must ignite
within 5 sparks once gas flows out of pilot hood. Pilot Flame must be at least 1-inch long and must overlap Flame
Sensor and burner ignition ports at all times.
Periodic visual check of main burner’s rear and front flames is required.

This Fireplace Insert arrives from the factory ready to burn Natural Gas. If you intend to burn LPG, it is highly recommended that you convert this fireplace and its Pressure Regulator, Pilot Orifice Clip and Burner Orifices prior to placing this fireplace in its fireplace cavity.
See diagrams, on this page, and follow these instructions to prepare this fireplace for conversion to LPG.
1. Using a ¼” Hex Driver, remove screws that secure the Rear and Front burners to the Burner Airbox.
2. Pull forward and remove Front Burner.
3. Loosen Front Burner Air Shutter Screw and rotate air shutter open ¼” minimum. Secure Air Shutter Screw. Set burner
aside.
4. Pull Rear Burner forward about 1” and lift up and remove from Firebox.
45
5. Using a ½” deep well socket wrench, remove Front and Rear Orifices.
HINT: PACK SOME SOFT PAPER OR INSWOOL INSIDE DEEP WELL SOCKET TO STOP CAP ORIFICE FROM
SLIDING TOO FAR INTO THE SOCKET.
6. Thread a new 3/64” drilled orifice to the Front Orifice mounting brass fitting and new #53 drilled orifice to the Rear Orifice mounting brass fitting. Tighten down orifices.
7. Locate Pilot Light on left side of firebox. While holding the pilot base body with large vice grips tightly, loosen Pilot
Light’s hex shape base using a ½” open end wrench. Rotate counter clock-wise ¼ turn to loosen.
8. Pilot arrives from the factory set for NG. Push NG/LP Adjustment Clip inward all the way to set it for LP. See detail
view, below. If you see “NAT” printing on the Adjustment Clip, this indicates that the pilot is set to burn NG. Push Clip
in so that “NAT” is not visible.
9. Tighten down Hex shaped base of pilot using a ½” open end wrench.
46
.
10. Before reinstalling burners, loosen the screw that secures the rotary air shutter on the Front Burner. Rotate the air
shutter open to ¼” minimum.
11. Install both rear and front burners in their original locations and positions and secure down using screws you removed
earlier.
12. Make certain front and rear burners are running parallel to front face of unit and positioned properly so that the pilot
light flames are pointed properly towards the burner’s flame propagation ports.

INSTALLING THE LP PRESSURE REGULATOR
WARNING: READ AND UNDERSTAND ALL INSTRUCTIONS PACKAGED WITH LP PRESSURE REGULATOR BODY
BEFORE YOU ATTEMPT THE CONVERSION. FAILURE TO FOLLOW ALL INSTRUCTIONS WILL RESULT IN A LEAK
OR OVERFIRING OF THE APPLIANCE AND CAN LEAD TO AN EXPLOSION OR A FIRE HAZARD.
1. Remove the Courtesy Access Panel mounted behind the lower grill and lay down gently without disconnecting any
wires of internal components. WARNING: DO NOT FORCE. EXCESSIVE FORCE MAY DAMAGE INTERNAL
WIRING COMPONENTS!
2. Follow Instructions given below directly from SIT Controls. Replace Extension Knob as the final step.

LP GAS PRESSURE REQUIREMENTS
Inlet and manifold gas pressure checking taps are located on gas valve. These ports are only accessible from the outer left
side of the fireplace. A qualified installer shall take pressure measurements at these ports to verify and set the correct gas
pressures during the LP Kit installation and before fascia materials are installed over the front of this fireplace. Manifold
pressure must be taken at the “MANIFOLD PRESSURE" tap and inlet pressure at the "INLET PRESSURE" tap with the
burner operating by a qualified installer.

LPG PROPER INPUT RATES
With the proper orifices installed, as specified above,
this fireplace utilizing LP Gas will have a maximum
input rate of 31,000 Btu/Hr.
LEAK TESTING REQUIREMENTS
Prior to completing the conversion process, check for
gas leaks with soap and water solution at all plumbing
joints prior to placing this appliance into operation. It
is recommended that all gas-plumbing joints, factory
installed and field installed are checked for leaks.
PILOT FLAME AND MAIN BURNER RELATIONSHIP
VERIFICATION
INLET TAP
OUTLET TAP
Figure 5: Pressure Test Port
Prior to completing the conversion process, the qualified service technician must,
light the pilot light and verify the relationship between the pilot light flames and the main burners. The pilot light flames directed towards the propagation ports on the rear and front burner must overlap the propagation ports on the burners. The
pilot light flames must be a minimum of ¾” long and must overlap the propagation ports on both the rear and front burners
as shown in the diagram, below. Verify that the burner tubes ignite quickly and the burner flames propagate smoothly
along the entire length of the burners.
PILOT FLAME LENGTH ADJUSTMENT
If the pilot light flame length is too short and the system does not maintain a standing pilot, a qualified installer may increase the length of the pilot light flames to meet the two requirements: Minimum pilot light length to maintain a standing
pilot light and the pilot light flames must be long enough to overlap the front and rear burner ports, 1 inch long minimum.
CHECKING FOR NORMAL BURNER(S) IGNITION CHARACTERISTICS
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.
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.
