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 and efficiently heats and re-circulates room air. The Mendota system maintains high air quality, maximizes efficiency and assures proper operation in today's "tight" homes.
SAFETY AND STRUCTURAL CONCERNS
This 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. If pilot goes out always wait five (5) minutes before relighting pilot. ALWAYS!
VENTING REQUIREMENTS
This Mendota Fireplace can be vented using AMERIVENT, DURAVENT, SELKIRK METALBESTOS, SECURITY
CHIMNEY and ICC brands of coaxial pipe off the top. Use only Mendota specified vents and vent caps when installing your fireplace. Closely follow venting locations, directions and requirements. Observe the restrictions relating to vent position on exterior of home. Be sure all vent pipe sections are fully twist-locked and leak-proof. Be sure Milpak Sealant is used on the inner pipe joints of all Simpson DuraVent pipe components and all adjustable pipe sections manufactured by
Simpson DuraVent and American Metals.
REMOVE THE GLASS WHEN LIGHTING THE PILOT FOR THE FIRST TIME. The burners must light immediately & the flame must travel promptly and smoothly around "curves" and light entire burner. The flame must not "lift" off burners. DO
NOT operate unit if burner does not light immediately or if flame lifts off burner.
peting, 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 may be installed above top of the heat outlet grills. How far out the mantel may protrude past the front face of this appliance is dependent on the distance from
with steel protector plate on underside can be installed at any desired height above upper grill.
Never block upper or lower grills. Always use Mendota grills and Mendota approved vent systems and vent caps.
A non-combustible hearth protector is required and must extend a minimum of 12" in front of the fireplace. If fireplace is raised off floor 6" or more, no hearth protector is required.
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 by up to 23,000 BTUH by slowly turning the Hi/Lo temperature knob on the gas valve counter clockwise from "Hi" to "Lo" and also turning OFF the rear burner using the Rear Burner ON/OFF Switch. Blower can also be turned down to reduce heat output.
AESTHETIC CONSIDERATIONS
Burning or static fireplaces are a major aesthetic focus in any room. Locate your gas fireplace as you would a television set. The Mendota Hearth Gas Fireplace will be a continuing source of comfort and fascination. Corner installations will afford you the greatest potential for viewing in many rooms.
We suggest installing the Mendota Fireplace 6 to 12 inches above the floor by utilizing an elevated hearth.
ELECTRICAL REQUIREMENTS
A 115-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. Electrical Service must enter this appliance at the Right Side Junction Box. Power supply to blower must be continuous. DO NOT use switches or speed control devices in power supplied to fireplace.
The blower on this appliance is equipped with a three-prong plug for protection against shock hazard and should be plugged 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 Transmitter. There will be delays in blower operation during "heat-up" (approx. 10 min.) 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.

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.
TOP VENTING
The DXV-35 Fireplace comes from the factory configured for venting off the top using 4” x 6-5/8” Coaxial Vent Pipes.
AMERIVENT, DURAVENT, SELKIRK METALBESTOS, SECURITY CHIMNEY and ICC brand pipes and venting components may be used when venting off the top.
Venting off the top on the DXV-35 Fireplace provides a large degree of flexibility for many venting configurations. However, a few critical limitations must be understood and adhered to.
Limitation 1:
A 12” minimum vertical pipe section must be connected to the top starter collar of the DXV-35. With the
12” vertical section connected, you may only install one 90-degree elbow and a run a maximum 6” horizontal pipe section before connecting the horizontal vent cap.
Limitation 2
: The maximum horizontal run allowed when venting off the top is 12 feet preceded by a minimum 4 feet vertical run. This 12 feet horizontal run can only be used if a straight vertical run of 48 inches (4 feet) is connected directly to the top of the dxv35. Do not exceed the maximum 12 feet horizontal run. Even if the vertical section you installed is greater than 4 feet, do not exceed the 12 feet maximum horizontal run throughout the entire vent system

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 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.

GENERAL FLUE VENTING INSTRUCTIONS
The Mendota Fireplace must be vented using Amerivent, Duravent, Selkirk Metalbestos, Security Chimney or ICC Brand venting systems. 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 approved by Mendota; failure to meet all clearance requirements; failure to properly twist-lock and positively seal all components. Consult local building codes before beginning the installation.
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 rooftops; 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 another solid fuel or gas burning 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 Fireplace, it is critical that all brands of 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.
We Strongly Recommend That Fixed Length Pipe Sections Be Used In Place Of Telescoping Sections Whenever
Possible.
Note: When using vent pipe and components that do not incorporate a fiberglass or graphite gasket at the joints, it is recommended that you use Milpak 1000F silicate stove sealant (#65-06-00909). High temperature foil tape may be used on the outer (air intake) pipe joints.
DO NOT SEPARATE ADJUSTABLE TELESCOPING SECTIONS. THEY MUST BE USED AS COMPLETE
ASSEMBLIES.
VENT COMPONENTS "TWIST-LOCK" CONNECTION PROCEDURE
DuraVent and American Metals 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 3).
Push the pipe sections completely together then twist-lock one section clockwise, approximately ¼ 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. They may be located by examining inside of the female ends .
Figure 3: Twist-Lock Piping

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 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) home 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.
This Fireplace must be installed by a qualified service person.
1.
After selection of the desired fireplace location, prepare the rough opening using framing dimensions on PAGE 164.
Be sure to also prepare opening to allow for co-axial vent (see "Flue Venting Instructions".
2. Check to make certain all venting requirements and clearances are being followed.
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 MATERIALS LOCATED ABOVE FIREPLACE BODY MUST
MAINTAIN CORRECT CLEARANCES TO VENT PIPE.
WARNING
DO NOT COVER THE 2” BLACK FRONT SURFACE OF THIS UNIT IF YOU INTEND TO USE THE ANDOVER,
BENTLEY, DEERFIELD or WELLINGTON TRIMS!!
4. Slide Fireplace into the rough framed opening. When finishing the unit, combustible materials may overlay nailing flanges and come in contact with the edges of the black front surface, but may not overlap the 2" black front surface.
Noncombustible material, such as marble, stones or brick, can be installed over the 2" black surface, only if you are certain that a Deerfield Front, Andover Front, Bentley Front, Prairie Front or a Wellington Front is NOT
going to be used as the optional trim, up to the inside edge of black frame (next to glass). ROUGH FRAMING
CAN COME NO CLOSER TO UNIT THAN THE STAND-OFFS.
5. 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 secure fireplace to floor using lag screws or drywall screws, if required.
NOTE: A removable panel in the enclosure for future visual inspection of flue connection is recommended.
6. Have an electrician install a 115-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.
7. Have gas supplier or qualified plumber install gas supply line to fireplace and connect to gas nipple. Be sure Gas
Supply Requirements (see PG. 9-10) and all local and national codes are carefully followed.
IMPORTANT: Any safety screen, guard, glass or grills removed for servicing a fireplace/room heater must be replaced prior to operating the fireplace/room heater.
BLOWER OPERATION
This fireplace is designed so the blower operates continually when the body is of this fireplace is hot and the main burner(s) are on. The blower output can be regulated with the included blower speed control rheostat. NOTE: There will be a delay before the blower operates during "heat-up" (approx. 10 minutes) and extended blower operation during "cooldown" of unit (approx. ½ hour).
OPERATION DURING POWER OUTAGES
The fireplace is designed to operate during power outages for 1-1/2 continuous hours, Maximum on HIGH FIRE. 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
15
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 LOW FIRE (front burner only), you may operate continuously during power outage.

For L.P. gas and high altitude installations (above 4,000 ft.), 45° elbows must be used in place of 90° elbows. height to center of vent cap. height from floor level will be 55-3/4" when using this minimum configuration. Adjust ceiling height upward for other configurations.
CAUTION: If 90° elbows must be used, a 24 inch vertical starter section must be used off the top of the fireplace.
19
MINIMUM RISE THROUGH-THE-WALL VENTING
:
The minimum vertical rise for vent installation through the wall is 16 1/4" from the top of the fireplace to the centerline of the 90ºelbow in installations where only a 6” (or 7”) horizontal vent section is used (refer to chart on PG.16 when using horizontal sections). NOTE: We recommend always using the most vertical rise the installation will allow. This maximizes efficiency and flame appearance. This is especially true for LP gas installations and for installations at higher altitudes.
Use "fixed" pipe sections in place of adjustable pipe sections wherever possible. 1000º sealant use is recommended on inner pipe joints. Always maintain 1" clearances from vent pipe sides and bottom to combustibles, 3" above pipes on horizontal runs and above elbows. Do not fill air spaces with insulation or other material.
For L.P. gas and High Altitude (above 4,000 ft.), 45º elbows must be used in place of 90º elbows.
NOTE: This requires 19" minimum rough opening depth (see PG. 15). CAUTION: If 90º elbows must be used, a 2-foot vertical starter section must be used directly off the top of the fireplace.
THIS FIREPLACE MUST BE INSTALLED BY A QUALIFIED MENDOTA APPROVED SERVICEPERSON.
IMPORTANT: REFER TO DRAWINGS ON PAGES 14-17 WHILE FOLLOWING THESE INSTRUCTIONS.
1. Position fireplace in desired location. See PG. 11 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.
2. Measure from the top of the fireplace up minimum (see Figure 4: Specifications & Clearances, PG. 164) and mark wall directly at the center of where the vent pipe will penetrate the wall.
3. Cut and frame a 9" wide x 10" high rectangle opening in the 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 non-combustible material, i.e. masonry block, brick, etc., a 7-inch diameter hole is acceptable.
4. Assemble the components to the fireplace adapter with pipe seams oriented toward the wall or floor -- as much out of view as possible. Be sure all vent component connections are in their fully twist-locked position and are leak-proof.
Be sure 1000ºsealant is used on the inner pipe joints of all pipe sections manufactured by Simpson DuraVent. American Metal pipe joints do not require this sealant.
NOTE: DO NOT SEPARATE TELESCOPING SECTIONS. THEY MUST BE USED AS COMPLETE ASSEMBLIES.
5. 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 (3" above horizontal runs and on top of elbows).
6. A wall thimble must always be used when penetrating combustible wall materials.
NOTE: Combustible wall thickness must be 4" to 8" maximum for the wall thimble. Wall more than 8” thick will require special protection. Contact Mendota Technical services for assistance.
7. 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.
WARNING : Venting terminal shall never be recessed into wall cladding or siding. Vent Cap must sit on top of siding or cladding.

ELEVATED VERTICAL RISE THROUGH-THE-WALL VENTING
The required MINIMUM vertical rise is 48 in. when used with a maximum horizontal run of 12 ft. For other venting configurations within these maximum limits, see Figure 6, PG. 18.
NOTE: All horizontal runs of vent pipe must be level or 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 12' horizontal run. Each additional 90º elbow reduces the maximum horizontal distance by 3'. Example: by using three total 90º elbows the maximum horizontal distance has been reduced to 6 ft. (3 - 1 = 2 elbows x 3' = 6'; 12’ Max. - 6' of elbows = 6' of horizontal run). Note: 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: If a vertical-to-horizontal elbow is enclosed within a wall, floor or ceiling, a top air space clearance of 3" must be maintained above the elbow. Be sure to maintain 1" air space to any combustibles on the sides and bottom, 3" above horizontal pipe sections.
THIS FIREPLACE MUST BE INSTALLED BY A QUALIFIED MENDOTA APPROVED SERVICEPERSON.
IMPORTANT: REFER TO DRAWINGS ON PAGES 14-17 WHILE FOLLOWING THESE INSTRUCTIONS.
1. Position fireplace in desired location. See PG. 13 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 want to adjust the fireplace location.
2. Locate the 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 (See Figure 2: Exterior Vent Locations,
PG. 13). Be sure all vent components are properly twist locked and leak-proof. It is recommended that 1000º sealant be used in the inner pipe joints of all pipe sections manufactured by Simpson DuraVent.
NOTE: DO NOT SEPARATE TELESCOPING SECTIONS. THEY MUST BE USED AS COMPLETE ASSEMBLIES.
3. Cut and frame a 9-1/2” wide x 10” high openings in the outside wall openings and 9” x 9” opening in ceiling openings. The outside wall hole must be positioned so the vent system will run level or have a ¼" on rise AND be perpendicular to the wall. The height of the opening must be located to meet all building codes and not allow the termination to be easily blocked or obstructed. A ceiling fire stop spacer is required at all floor (ceiling) penetrations.
4. Connect vent pipe to the fireplace adapter on top of fireplace vent outlet.
5. The horizontal pipe must end flush with the exterior wall of the home. Horizontal pipes will require proper support every 3 ft. of vent pipe. THERE MUST BE A MINIMUM OF 1" CLEARANCE TO COMBUSTIBLES ON THE
SIDES AND BOTTOM OF ALL VENT PIECES (3" above horizontal runs and above elbows).
6. A wall thimble must always be used when penetrating combustible wall materials.
NOTE: Combustible wall thickness must be 4" to 8" maximum for the wall thimble. Wall more than 8” thick will require special protection. Contact Mendota Technical services for assistance.
7. 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.
WARNING
: Venting terminal shall never be recessed into wall cladding or siding. Vent Cap must sit on top of siding or cladding.
22
VERTICAL THROUGH-THE-ROOF VENTING
The
maximum vertical run of vent pipe is 55 ft. from the top of the fireplace. The fireplace will support a run of a maximum of 55 ft. The vent system must be supported every 3 feet using Support Straps. Maintain 1" air space clearances on all sides of vent components that are positioned vertically and 3” above horizontal pipe sections and components.
THIS FIREPLACE MUST BE INSTALLED BY A QUALIFIED MENDOTA APPROVED SERVICEPERSON.
IMPORTANT: REFER TO DRAWINGS ON PAGES 14-17 WHILE FOLLOWING THESE INSTRUCTIONS.
1. Place the fireplace in its desired location. Drop a plum bob from the ceiling to the 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 plum 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 choose to relocate the fireplace or choose to offset the vent system to avoid cutting load bearing members.
2. Cut and frame a 9" x 9" opening in the ceiling centered on the hole drilled in Step 1.
3. 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.
4. Assemble the desired lengths of vent pipe and elbows to reach from the fireplace flue outlet. Ensure that all vent pipe and elbow connections are in their fully twist-lock position and that inner pipe joints are sealed and are leak-proof.
Maintain 1" airspace clearances to combustibles around vertical pipe sections and 3" clearance above horizontal run sections.
5. Cut a 9" x 9" opening in the roof, centered in the small drilled hole placed in the roof in Step 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. a) 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 are available for this purpose. b) 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 one pipe section rise between the 90º elbow and the vent cap. A maximum of three 90ºelbows are allowed per installation.
6. 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.
7. 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. a) 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 9" x 9" inside dimensions as described in step No. 5. b) 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.
8. Height "*H" of top of vent cap can be determined as follows:
9. Complete installation with storm collar and vent cap.

DXV-35 DT3 DEEP TIMBER LOG SET INSTALLATION INSTRUCTIONS
FOLLOW EACH STEP DEPICTED IN THE DIAGRAMS, BELOW, TO INSTALL THE LOG SET.
CAUTION: LOGS ARE FRAGILE, HANDLE LOG PIECES WITH CARE.
Carefully unpack 9-piece log set, bag of coals and bag of inswool. NOTE: Logs are very fragile, handle with care. Break packaging foam if log pieces are trapped within foam. Do not pull on logs!
Coals must not block pilot or burner flames ! Placement of coals has a big effect on front burner flame appearance and "glow" of coals. More coals = less yellow flame and more glow. Fewer coals = more yellow flame and less "glow".
Heat can be reduced by lowering flame height by turning the HI-LO knob. Blowers can also be turned down to reduce heat output.
Do Not “over fire" by increasing Gas Input Rate above Rating Plate specifications.
Do Not turn down pilot flame length less than 1 inch long.

INSTALLATION CHECK OFF LIST
Co-axial vent rigid pipe, wall vent cap or roof vent cap must be installed by a Mendota approved person in accordance with instructions. All joints must be secured, "twistlocked" and leak-proof. 1000ºF sealant use is recommended on the inner pipe joints of
DuraVent pipe sections.
Horizontal or vertical vent cap must be installed " right-side-up" and tightly sealed to structure per instructions. Vent Caps must be Mendota approved.
Clearances to combustibles requirements must be strictly adhered to.
Proper exterior and interior clearances for vent systems and locations for wall vent cap/roof vent cap must be maintained.
Carefully check for correct gas pressure, proper size gas lines and for gas leaks.
115 V electrical service and gas supply must be installed in accordance with instructions and local and national codes.
LIGHTING CHECK OFF LIST
All items on "Installation Check Off List" (see above) must be completed.
Connect thermostat, if desired. Disconnect wires connected to Main On/Off switch and connect thermostat lead wires to these two wires and run to thermostat location.
Check air shutter opening - 1/16" to 1/8" Nat. gas or 1/4" Min. LP gas.
Carefully follow all Lighting and Log Installation Instructions.
Make certain that burner lights immediately and flame runs promptly around "curve" in burner and lights entire burner. DO NOT proceed with operation unless burner cycles
"on/off" without delays.
Make certain that the flame is "stable" and does not "lift" off burner. If flame lifts off burner, turn unit off and check that all vent pipes are "twist locked" and leak proof, the vent cap is "right side up". DO NOT proceed with operation if flame is "lifting off" burner.
Note: do not separate telescoping sections. They must be used as complete as-
semblies.
Make certain glass door is in properly closed and "centered" in firebox opening.

BEFORE YOU BEGIN
Read this entire manual before you use your new fireplace. Failure to follow the instructions may result in property damage, bodily injury, or even death.
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 “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.
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.
Standing Pilot Mode
: If the “Standing Pilot Switch” is toggled to ON, the pilot light will ignite and remain 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 o 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.
ATTENTION!
The transmitter and receiver are RADIO FREQUENCY DEVICES. Placing the receiver in or near metal may severely reduce the signal range.
• Turn off the main gas supply of the appliance during installation or maintenance of the receiver.
• Place the receiver’s 3-position slider switch in the “off” position during installation or maintenance.
• Turn “off” main gas supply to the appliance prior to removing or reinserting the batteries in the receiver.
• During appliance installation/maintenance or in case of remote control malfunction, turn off electrical supply to this appliance and remove the batteries from the wall receiver battery compartment. Contact technical service.

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 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, this system utilizes the batteries (installed in the Wall Receiver) as backup 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.
This appliance is designed and tested to be operated during power outages. The overall efficiency of this appliance will be reduced by approximately 5% when the blower function is disabled during the power outage period.
41
“FIRST TIME” PILOT LIGHTING INSTRUCTIONS
IMPORTANT: Be sure all items on "INSTALLATION CHECK OFF LIST" in the Installation Manual have been completed!
CAUTION: If the pilot goes out, be sure to wait a minimum of five minutes before attempting to relight the pilot.
1. Make certain that any manual gas supply shut-off valves located upstream of fireplace are open and the receiver and the remote control transmitter are in the "OFF" position. Make certain that the receiver harness is connected to the wall receiver properly.
2. Make certain that 110VAC power is connected to Electrical Junction Box on right side of Fireplace and that the Electrical Power is “ON”.
3. Insert Batteries in the Receiver and the Remote Transmitter. Note the polarity of batteries and insert as indicated on the battery compartment covers.
4. For the “First Time Lighting”, Remove the Glass Door. This is required to purge the gas line of air and to inspect the pilot lighting spark.
5. Slide the receiver switch to “REMOTE”. Locate the “Standing Pilot ON/OFF Switch”.
6. Toggle “Standing Pilot ON/OFF Switch” to “ON”. You will hear a series of clicks and after a few seconds, you will hear sparking at the pilot spark electrode.
7. Allow adequate time for the air in the gas-line to purge. The control system will stop sparking after 30 seconds if the pilot light does not light. After a 30 second delay the control system will start sparking again for 30 seconds more. If the pilot light does not light after the third 30 second spark event, the system will enter “Lock-out” mode. To unlock from “Lock-out” mode, slide Receiver Switch to “OFF” and toggle “Standing Pilot ON/OFF Switch” to “OFF”, wait 30 seconds and slide back to “Remote”. Repeat this sequence until the pilot flame lights and the pilot is burning steadily.
7. Once the pilot flame is lit and well-established, close glass door. WARNING: NEVER IGNITE MAIN BURNERS
WITH GLASS DOOR REMOVED OR OPEN. Doing so will lead to damage to pilot flame sensor and spark elec-
trode wire leads.
8. Slide switch on Receiver to “ON”. All burners should ignite and run at “high-fire”. Slide Receiver switch to REMOTE after 15 seconds. Burner Flames will extinguish.
9. Perform gas inlet and outlet pressure tests and leak tests on field installed gas fittings and factory installed fittings in the gas valve compartment, at this time. Note: Burners must be ON to check outlet pressures and to leak test gas train fittings upstream of main gas valve.
INITIALIZING THE REMOTE CONTROL SYSTEM
(Synchronizing Receiver and Transmitter)
1. Place 3-position slider switch in Receiver in the “Remote” position.
2. Locate “PRG” key on Receiver Face. Use the tip of a pen/pencil or a wire clip to push the PRG button. The receiver will beep 3 times indicating that it is ready to synchronize with a Remote Transmitter.
3. Push the “ON” key on the Remote Transmitter. The receiver will beep 4 times to indicate that the Transmitter’s command is accepted and sets to the particular code of that Transmitter. The system is now initialized.

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 DXV35 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 rheostat. 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 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.

TROUBLE SHOOTING MENDOTA GAS DXV FIREPLACE
SYMPTOM
1. Thin black coating
(soot) forms on viewing glass.
2. Humming or whistling coming from Fireplace.
3. A change in flame appearance or burner operation.
PROBABLE CAUSES
A. Incorrect gas pressure
B. Not enough combustion air
A. Normal operating noise.
A. A change in gas pressure.
B. Carbon, dirt or lint
CORRECTIVE ACTION
Have gas supplier check for correct gas pressure (7" W.C. Nat. Gas; 12"
W.C. LP Gas).
If sooting continues open air shutter on burner (see "Gas Flame Adjustment" below).
If sooting still continues, shut off unit and call Mendota service person.
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. Turning the Hi/Lo Knob on the control can reduce the noise. Turning down the flame will reduce the heat output of the unit.
Have your gas supplier check for correct gas 7" W.C. Nat. Gas; 12" W.C.
LP Gas). If flame still needs adjustment see "Flame Adjustment" below.
Clean out carbon, spider webs, lint, etc. from shutter area.
Logs and burner.
NEVER BLOCK AIR INTAKE OR OUTLET VENTS.
FLAME ADJUSTMENT
Be sure burner and logs are properly installed .
After logs have been properly installed and operated for one to one and a half 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. One Air Shutter Control is located behind lower hinged grill on the right side. This controls the rear burner shutter. This shutter control controls the rear burner flames. The front burner shutter is of the rotary-type. The front burner shutter is factory adjusted for Natural Gas at 1/8” open. For LPG, open to a minimum ¼”.
2. Light pilot; install logs and glass, and burn unit for 30 minutes.
3. If flame is too "blue" push Air Shutter Control Knob inward until flame turns yellow.
4. If flame is too "orange" or is causing sooting open shutter until flame begins to turn blue. NOTE: If sooting does not stop, turn off fireplace & call Mendota Service Person .
5.
IMPORTANT: Try each new shutter setting approx. 1/2 hour before making additional changes.
NOTE: Changes in front burner flame can be made by re-arranging the coals and rock wool. Densely packed coals will yield more glow and blue flames. Loosely packed coals will yield less glow and yellow flames.
CAUTION: Any changes in pilot flame length must be made by qualified person only.
45
CUSTOMER INFORMATION AND TROUBLE-SHOOTING
MAXIMUM ALLOWABLE SURFACE TEMPERATURE
Mendota Fireplaces comply with UL Standards for maximum surface temperatures on exposed combustible surfaces adjacent to the unit. 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 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 you may turn on the burners for maximum 1-1/2 hours at a time with a 1 hour cooling period in between the burn cycles. Do not exceed the 1-1/2 hour burn time during power outages.
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
If pilot flame goes out, always wait 5 minutes before relighting.
CLEANING VIEWING GLASS
The viewing glass should be cleaned periodically. Exterior glass surface may be cleaned with cleaner as desired. The
Interior glass surface should be cleaned using only soap and water or KEL KEM “Polish Plus” or comparable product.
CAUTION
: Do not use oven cleaner to clean glass. Never touch glass or attempt to clean 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” (part # 65-06-
00455) or comparable product (contact your dealer).
In some cases (especially when burning propane) additives can cause “crazing” or etching on the glass. This is not an uncommon occurrence and it is not covered under the warranty. The solution may be to change propane suppliers.
SOOTING
Sooting is caused by improper installation or operation. 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. 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.
46
MAINTENANCE
