1.1 CAUTION STATEMENTS TO PARENTS OF YOUNG CHILDREN

If th is fireplace is installed in an isolated bedroom, study o r oth er room, always operate this appliance in thermostatic temperature -contro ll ed mod e. Do not operate in Manual mode. Doing so can lead to very high room temperatures which can be hazard ous t o the room occupants’ health.

Do not place young children in cribs, bassinets or the like in th e vicinity o f t his appliance. Young child ren may be vulnerable to high temperatures that this fireplace ca n create locally.

Young children should be carefu lly supervised and never left unatt end ed when they are in the same room as the fireplace. Toddlers, young children and others may be susceptible to accidental contact burns. A physical barrier is recommended if there are at risk individual s in t he house. To restrict access to a fireplace or stove, install an adjustable safety gate to keep toddlers, young children and oth er at risk individuals out of the room and away from hot sur fa ces. Th is physical barrier is in addition to th e required glass barrier Screen.

1.2 INITIAL FIRING AND CURING PROCEDURE

This product requires an initial heat curing cycle during which some materials used in the manufacturing process will burn off and the powder paint goes through a hardening cycle. During the initial curing phase, some smoke and odor will be emitted. This is normal. The installer should perform these initial curing cycle procedures as the final step in the installation process before finishing materials are installed around this fireplace. See chapter 3.1.1 Mendota Fireplace Curing Instructions. Read and follow all instructions given in this Chapter and perform the 3-step curing cycle. After the 3-step curing cycle has been completed, all smoking will have stopped. Some slight odors may remain. With subsequent use of this Fireplace, odors will slowly dissipate and disappear.

ODOR RISKS

If th is appliance is not operated for an extended p eriod ( three months or longer), when first fired again, exp ect odors of burnt dust and lint; just like when turning on your home heating system for the fir st time in the Fall.

1.3 HOT SURFACES ARE NORMAL

Be aware that the surface in front of, above and adjacent to this heater appliance can be too hot to touch. As long as all required clearances to combustibles are met and the required finishing materials are used, this appliance will perform safely. Note that the exposed surfaces immediately surrounding the Fireplace can have surface temperatures that are too hot to touch. This level of surface temperature is considered normal and does not indicate any hazardous situation.

WARN ING: The supplied barrier scre en must be installed, always, when this fireplace is in operation. Do not place any object directly in front (within 60”) or directly above (on t he front edge of the mantel). This is a heating appliance. Areas directly in front and above this appliance wil l b e very hot and can damage most household objects if placed too close. Keep Furniture pieces at least 60” away in front of the barrier screen.

1.4 PERIODIC AND ANNUAL CLEANING ARE REQUIRED

See Required Periodic Inspections, Chapter 6.1 and Required Annual Maintenance, Chapter 6.3. Periodic and Annual cleaning and general services are required at least once a year in the Summer or early Fall. Cleaning thermocouple, thermopile, pilot sparker rod and pilot hood body is required at least once per year. Cleaning of burner ports, gas orifice areas is required once a year due to insects’ nesting probability due to Mercaptan addition in Natural Gas (Mercaptan attracts insects).

TECHNICAL REFERENCES

Read and understand all information provided under this section, Technical References, before you begin the installation of this product. Failure to follow all technical reference information, use of components or parts not approved or use of improper installation procedures can lead to a fire or explosion causing property damage, personal injury or loss of life.

3.1 GENERAL TECHNICAL REFERENCES

Caution: Before igniting the pilot or burn er s, p er fo rm th e follo win g in sp ec tions and verifications:

Check glass gasket seal. Visually inspect glass gasket, especially at the corners of the glass piece. Glass gasket is installed as a 4piece assembly. Check joints between the gasket pieces at the corners. They should butt against each other to create a seal. Gaps between gasket pieces can cause exhaust leaks and lead to acrid smell concerns. Check for gas leaks at all fittings.

During the first burning cycle of this Fireplace, ensure the convection blower is running at level three during the first two hours of initial burn. After two hours of initial burn, allow fireplace to cool. Proceed with Mendota Fireplace Curing Instructions,

Chapter 3.1.1.

This fireplace must be installed and serviced by a qualified installer, service agency, or the gas supplier. Any adjustments to burner, pilot, logs or coal bed must be made by a qualified installer, service agency, or the gas supplier. If pilot goes out, always wait 5 minutes before attempting to relight pilot. Never block off convection air openings or paths. Trim panels or surrounds shall not seal ventilation openings in the fireplace. Always use Mendota decorative fronts and Mendota approved vent systems and vent caps only.

Keep the flue warm

It is required to leave the pilot light running during winter months when outside daily high temperatures remain 50oF or lower. Doing so will eliminate heat loss from the home through the Fireplace glass door and will increase flue draft during startups.

WARNING

FIRE RISK/ODOR RISK

• This fireplace must be installed on top of wood, masonry or metal floor extending the full width and depth of this

fireplace.

• An R-1 Rated Hearth Protection Pad, 12” deep, is required unless this fireplace is elevated at least 6” above floor

level of the room. For every 1” this fireplace is elevated, you may reduce the hearth pad depth by 2”. Locate and install appliance to all clearance specifications in manual.

Mendota Fireplace Curing Instructions

ATTENTION

It is important that the blowers are turned on dur ing this step to prevent the curing smoke from staining the wal l fini sh ab ove the fireplace. Mendota recommends completing Step 1 pr ior to install ation of wall finish mat erials.

Visib le smoke and strong odor are to be expected during this step. If desired, disable smoke alarms before this step, smoke from the initial curing c ycle will set off smoke alarm s. Open doors and windows of the ho me to circulate fresh air.

Step 1: Expelling Initial Smoke and Odors

• Please refer to ,LIGHTING INSTRUCTIONS, if you have questions on how to operate your Mendota.

• Complete the installation of any barrier screen (required), surround, front or doors.

• Turn the fireplace on

• Set the Flame Height to Hi.

• Set the Fan Speed Control to medium speed.

• Run the fireplace with these settings for a minimum of 2 hours.

• Turn the fireplace off and let it cool.

Step 2: High Heat Curing Cycle

• Turn the fireplace on.

• Set the Flame Height to Hi.

• Set the Fan Speed Control to Off.

• Run the fireplace with these settings until curing odors have diminished.

• When odors have diminished leave the fireplace turned on and continue to Step 3.

Step 3: Final Curing Cycle

• With the fireplace still turned on from Step 2.

• Set the Fan Speed Control to the lowest setting Level 1.

• If any new curing odors are detected, continue to run the fireplace with this setting until the curing odors have

diminished.

ATTENTION: Slight odors may still be noticeable on future startups of the fireplace. These will diminish over time as the

fireplace is used.

Additional Curing Information

It is not unusual for a fireplace to require more than 10 continuous hours on high for curing odors to diminish. There are variables that can extend or shorten the curing time such as decorative fronts, doors, facing materials and their application. Finish materials around the fireplace are subject to high temperatures. Finishing materials used over the fireplace in the noncombustible zone can see temperatures around 350° F. Materials used around the fireplace must be rated for these temperatures. Failure to use adequate materials can result in odor problems. Please refer to Chapter 3.2.4.3 of this manual for information on appropriate finishing materials. Please be aware that materials used around the fireplace will heat up and have the potential to cause odor issues. Adhesives, glue, wall substrate, wall finish material, paints and polishes are common materials that if used incorrectly will cause odor issues. Mendota is not responsible for any odor issues caused by materials used around the fireplace.

Constructing the Appliance Chase

A chase is a vertical box-like structure built to enclose this fireplace and its vent system. Vertical vents that run on the outside of a building may be, but are not required to be, installed inside a chase.

Construction of the chase may vary with the type of building. These instructions are not substitutes for the requirements of local building codes. Local building codes MUST be adhered to.

Chases should be constructed in the manner of all outside walls of the home to prevent cold air drafting problems. The chase should not break the outside building envelope in any manner.

Wall, ceiling, base plate and cantilever floor of the chase should be insulated. Vapor and air infiltration barriers should be installed in the chase as per regional codes for the rest of the home. Additionally, in regions where cold air infiltration may be an issue, the inside surfaces of the chase may be sheet rocked and taped for maximum air tightness.

To further prevent drafts, the fire stops should be caulked with high temperature caulk to seal the gaps. Gas line holes and other openings should be caulked with high temp caulk or stuffed with unfaced insulation. If the appliance is being installed on a cement slab, a layer of plywood may be placed underneath this fireplace to prevent conducting cold up into the room

Hearth Pad Requirement

A non-combustible hearth protector with a thermal insulation rating of R-1 is required when installing this fireplace directly on the floor and must extend a minimum of 12" in front of this fireplace. To build an R-1 rated hearth protection pad, begin by

laying down a ½” thick layer of an R-1 rated Mineral board (see 3.2.6.3 Suitable Finishing Materials R-Ratings) and then add a 1” thick top layer of noncombustible material such as stone, granite, marble or the like.

For every 1” the fireplace is raised off the floor, th e d epth o f th e required hearth protector may b e reduced by 2”. If fireplace is raised off t he floor 6" or more, no hearth protector is required for fire protection.

Caution: The fireplace creates localized heat and causes thermal expan sion of adjacently installed flooring and wall materials. Vinyl floor s and floating Engineered wood floors may warp if installed in front of this unit even when this fireplace is raised 6” or more due to local heating up of the floor mat erial s. Never use viny l or Engineered wood flooring in the hearth pad area in front of this fireplace u nless you p lan to raise this unit 12” or more above the floor level.

Caution: Modern carpets use polypropylene, nylon or polyester fibers in the upper visible layer. These fibers when exposed to radiant heat can curl and stiffen. It is not p ossible to prev ent radiation effects to the carpet fibers even when this unit is raised high. A void in stallin g carpets in the hearth pad area in fro nt of this Fireplace unless this fireplace is raised at least 12 inch es above the carpet level .

This fireplace may be installed in an elevated position by created an elevated deck and an appropriate framed enclosure. NOTE: This fireplace may be elevated but MUST allow a minimum of 72” distance between this fireplace’s floor level and the ceiling of the room.

Clearances to Combustible Mantels

An 8” combustible mantel may be installed at a minimum of 14" above the top of the heat outlet (41” up from the floor level of this Fireplace). Non-combustible (marble, brick, stone, metal etc.) mantels can be installed at any desired height above the top convection air opening. Any pre-existing combustible mantel must fall within the approved mantel profile chart.

WARNING: Make proper use of this chart. Do not compromise the specifications contained in this chart. Failure to adhere to proper clearances required to combustibles may cause spontaneous combustion of the mantel and may result in a fire causing property damage, personal injury or loss of life.

NOTE: For mantels that protrude more than 8 inches from the front surface of the fireplace use a rise and run of (7:4) to calculate the required height to the mantel. EXAMPLE: You have a 12" mantel. To calculate the height above the convection air opening the equation would be: 12" x (7/4) = 21" above the convection air opening. DO NOT deviate from this minimum clearance requirement. Doing so can lead to a severe fire hazard.

Note: The distance from the Floor Level of this Fireplace to the Top Air Gap is 27”.

85-03-01115 DXV35 TIMBERFIRE Page 24

Clearances to Combustible Side Walls

The minimum distance required from the side edge of the glass frame to a combustible side wall is 12”. Combustible side walls, mantel corbels, mantel legs and other combustible walls and decorative objects must fall behind a 45degree line extending outward from the side edges of the visible glass unless such objects are more than 12” away from the side edges of the glass frame. See Figure

3-25 Side Wall Clearances.

A wall, perpendicular and in front of this appliance's glass door face must be at least 12" away from the side edges of the glass frame.

A wall at a 45o angle to the front face and starting at the Side Edge of the Front Face of this appliance is allowed. Projections behind this 45o angle edge (shaded area) are allowed.

If the required clearance cannot be met to a pre-existing co mbu st ible side wall, an NFPA approved clearance redu ction shield, metal or ceramic boa rd, must be added to th e sid e wall.

3.2.4.4.1 Horizontal Clearance Reduction by 66%

NPFA 211 Approved: Install 20-gauge or heavier steel shield that provides at least a 1” active airspace, on the combustible wall

surface. To provide for active airflow, install at least 1” metal or ceramic standoffs or spacers between the metal shield and the combustible surface being protected. The bottom and top edges of the cavity between the metal shield and the combustible surface must be left open. The steel shield must be a minimum of 12” larger in each direction than the surface area of the source of heat; or if the surface being protected is smaller than surface area of the source of heat, this shield must be larger than the combustible surface in each direction. By using this method of protection, if the required horizontal clearance was 12”, the resulting clearance will be reduced by 66% to 4” between the heat source and the metal shield.

3.2.4.4.2 Horizontal Clearance Reduction by 50%

NPFA 211 Approved: Install an R-1 rated ceramic board or R-1 rated mineral board on the wall you are attempting to protect.

by using this method of protection, if the required horizontal clearance was 12”, the resulting clearance will be reduced by 50% to 6” between the heat source and the R-1 Rated wall board.

Normal Surface Temperatures

WARNING: The supplied barrier screen must be installed, always, when this fireplace is in operation. Do not plac e any object directly in front (within 60” from barrier screen surface) or directly above (on the front edge of the mantel). This is a heat ing appliance. Areas directly in front and above this appliance will be very hot and can damage most house hold objects if placed too close. Keep Furniture piece s at least 60” away in front of the barrier screen surface.

HINT: To greatly reduce surface temperatures surr ounding th is Fireplace during operation, Mendota recommends operating the integrated convect ion air blowers which aid in cool ing all surroundin g surfaces.

Mendota Fireplaces comply with ANSI Z21.88-2016 Standards for maximum surface temperatures (ambient plus 117oF) on exposed “combustible” surfaces adjacent to the Fireplace.

Be aware that surfaces in front of, above and adjacent to this heater appliance can be too hot to touch. As long as all required clearances to combustibles are met and the required finishing materials are used, this appliance will perform safely. Note that the exposed surfaces immediately surrounding the Fireplace can have surface temperatures that are too hot to touch. This level of surface temperature is considered normal and does not indicate any hazardous situation.

Hearth Pad Temperatures

New hearth protection pads installed are required to have a thermal insulation value of R-1. The top exposed surface of the noncombustible hearth pads can reach a temperature that is too hot to touch (as high as 250oF). This is considered normal.

Surround Face Temperatures

Areas of the breastplate directly above the top convection air gap of this Fireplace can be very hot (too hot to touch(exceeding 250oF)) and is deemed normal.

Mantel Temperatures

Mendota Fireplaces comply with ANSI Z21.88-2016 standards for maximum surface temperatures on

exposed “combustible” surfaces adjacent to the

Fireplace. Be aware that surface in front of, above and adjacent to this heater appliance can be too hot to touch. As long as all required clearances to combustibles are met and the required finishing materials are used, this appliance will perform safely. Note that the exposed surfaces immediately surrounding the Fireplace can have a surface temperature too hot to touch. This level of surface temperatures is considered normal and does not indicate any hazardous situation.

WARNING: Surfaces surrounding this Fireplace can be very hot to the touch during operation. Carefully supervise children and pets while this Fireplace is operating.

Suitable Mantel, Facing & Hearth Pad Materials

Use of ceramic glazed tiles as facing materials around a Mendota Fireplace is approved. Use caution when selecting tile adhesives. Avoid premixed tile adhesives which contain products that can off gas for long periods when exposed to heat. Use Portland cement based unmixed tile adhesives or RTV Silicone to attach ceramic glazed tiles as facing in hot areas around this Fireplace. If using RTV silicone apply in long wavy lines and allow a minimum 48 hours cure time for the silicone to cure before firing this Fireplace after tile application.

Figure 3-26 Hot Zones

Page 26

85-03-01115 DXV35 TIMBERFIRE Page 26

Marble, Granite and Natural Stones

Marble, granite and other natural stone products are approved for use as mantel, facing and hearth pad materials with the following limitations and understanding of these cautionary statements:

Never use a one-piece marble, granite or n atural stone that is water jet or mechanically cut in a U -shape as fac ing material to cover the sides and top ar eas around this product. Doing so can lead to crack formation at the inner corners of the U shape du e to thermal expansion.

Figure 3-27 Three Piece Stone

Most marble slabs and marble tiles contain a polyester resin coating while most granite slabs and granite tiles contain epoxy resin coatings. The polyester resin coatings and the epoxy resin coatings provide structural strength to the stone slabs and prevent cracking, chipping and breakage during shipping and handling. These coatings also provide a glossy or satin surface finish and help seal the stone surface.

Th e poly ester resin used on marble slabs can discolor when expo sed to temperatures greater than 150oF and will structurally fail at temperatures abo ve 230oF. The epoxy resin coating used on granite slab s are resistant to discoloring and structural failures up to 350oF.Mendota does not assume any liab ili ty fo r discoloring, flaking or cracking of marble or granite.

Temperatures on facings around Mendota Gas Fireplaces can reach 350oF directly outside the top convection air gap and as high as 210oF at the maximum allowed mantel protrusion level above the top convection air gap. These temperatures can discolor polyester resin coated marble facings and can cause the polyester resin coating to fail near the top convection air gap.

Mendota Fireplace cannot guaran tee suitability of use of any marble slabs or tiles that have a polyester resin coating applied to it and cannot guarantee against discolo ration or stru ctural failure of marble or polished stone facings that have a polyester resin coating. Consu lt with your local stone supplier.

Prior to use of any marble, granite or polished stone facing material, especially white colored ones, run heat exposure tests on a sample piece. Expose sample pieces to temperatures between 275oF and 350oF for a period of eight hours. Compare the heat exposed sample to a control unheated piece and judge for color changes. Do not use if any color changes are evident.

Mendota recommends the use of honed bare marble and bar e ston e facing materials or honed bare granite and epoxy resin coated granite only.

Mendota cautions that due to natural structural defects that can exist within marble and stone pieces, cracking and/or flaking of the marble or stone is possible and must be considered prior to selection and application around Mendota Fireplaces. Mendota further cautions that proper adhesives be used to attach stone facings. Pay attention to the potential of off-gassing of chemical vapors from mastic and other adhesives. Improper selection can lead to emission of chemicals with unwanted smells.

Suitable Paints and Sealant Materials

3.2.6.4.1 Paint Types Approved for Use

Industrial Acrylic Paints, Alkyd based Paints. When selecting paint for applications on facings, mantels, corbels or floors within

2’ in front of a fireplace raised 6” or higher, avoid off the shelf paints which may have modifier additives used to increase “hiding” ability, accelerate drying times and curing times. Consult with a reputable paints and sealants supplier and acquire

industrial acrylic paints or alkyd-based paints.

3.2.6.4.2 Sealants Type Approved for Use

Heat resistant polyurethane sealants which are not damaged by prolonged exposure to raised temperatures. Many are flame resistant, meaning that they resist ignition when exposed to high temperatures and can insulate the substrate and delay damage to it. When selecting polyurethane for applications on facings, mantels, corbels or floors within 3’ in front of or above a fireplace, avoid off the shelf urethane sealants which may have modifier additives used to accelerate drying times and curing times. Consult with a reputable paints and sealants supplier and acquire heat resistant polyurethane sealants.

3.2.6.4.3 Wood Application Cautions

If wood used around or in front of the fireplace has been chemically cleaned or bleached prior to staining or painting, it is of the utmost importance to make certain that the cleaner or bleach does not remain in the wood substrate under the final paint or sealant applied. If any cleaner or bleach remain within the wood structure, application of heat from the fireplace, even low-level heat, will cause the cleaner or bleach compounds to expand or evaporate causing separation of the paint or sealant from the wood surface and may cause peeling or bubbling of the paint or sealant. Moisture content of the wood substrate is also of critical importance. High moisture content wood when heated will yield evaporation of the moisture and hydraulic pressure under the paint or sealants which can lead to peeling or bubbling. Always select the lowest moisture content wood substrate.

Recommendations for Television Installation

Note: The model depicted in the images is a representation of a Mendota Hearth fireplace. These recommendations apply to all

Mendota Hearth Fireplaces. When planning to install a television or other heat sensitive product above your fireplace, there are some points to consider. Many television manufacturers specify in their installation instructions that the television must not be installed near or above a

heat source. The decision to install a television near or above a Mendota fireplace rests solely on the consumer. It is the consumers responsibility to satisfy television specifications and insure the television will not exceed maximum operation temperatures. Mendota Hearth will not be held liable for any adverse effects on a television or other products located near to a Mendota Hearth fireplace.

The drawings below show recommendations that may be used as a guide for those consumers that decide to locate a television above a Mendota Hearth fireplace. These recommendations have been found to reduce the heat impact to a television when installed above a Mendota Hearth fireplace.

Recommendation 1: Add a mantel

Add a mantel above the fireplace. The mantel shall be at least 2 inches deeper than the depth of the television, and at least as wide as the television. The mantel shall be mounted so that its top surface is a minimum of 18 inches above the top air gap of the fireplace.

Attention: If the mantel is constructed of combustible materials, make certain that the entire mantel meets the clearances to combustible mantel requirements.

Page 30

85-03-01115 DXV35 TIMBERFIRE Page 30

Recommendation 2: Create a recessed cavity

Frame a recessed cavity above the fireplace. The cavity shall be at least 6 inches taller and 6 inches wider than the television. The cavity’s bottom surface must be a minimum of 24 inches above the top air gap of this fireplace. The cavity must be deep enough for the television to be recessed at least 2 inches in from the wall.

Recommendation 3: Install a heat transfer system

Mendota Hearth offers three heat transfer systems that take heat from the fireplace and redirect it to another area. When used correctly these heat transfer systems can make it possible to mount a television above the fireplace without installing a mantel or creating a recessed cavity.

Note: Heat transfer systems are not available for use on M27 model fireplaces. WARNING: The convection fans on the fireplace must be turned off to insure the heat from the fireplace is redirected through the

heat transfer system. Turning the convection fans on will force heated air out the front of the fireplace, heating the surrounding area.

- On fireplaces with a millivolt system: DXV35 Timberfire, DXV42, DXV60, M50 the convection fans must be disconnected

from power to insure they cannot be turned on.

Page 31

85-03-01115 DXV35 TIMBERFIRE Page 31

- On fireplaces with electronic ignition system that come with a PF2 remote the convection fans function must be

programed out of the remote. This will ensure that the convection fans cannot be turned on. Follow the directions below to remove the convection fans function from the remote.

1. Remove a battery from the remote.

2. Hold down both the ON/OFF key and MODE key

and reinstall the battery.

3. Continue to hold the ON/OFF key. Release the

MODE key. Press the MODE key once to highlight the convection fan function.

4. While still holding the ON/OFF key press the DOWN

ARROW key. The display will change from “Set” to “Clr” to indicate that the convection fan function

has been disabled.

5. Release the ON/OFF key.

3.2.7.3.1 Mendota Cool Wall

The Mendota Cool Wall system uses natural convection to take heat off the wall directly above the fireplace and redirects it up and away from surrounding areas. Testing has shown that when using a Cool Wall system, temperatures above the fireplace are reduced making it possible to mount a television 15” above the fireplace’s top air gap.

Page 32

85-03-01115 DXV35 TIMBERFIRE Page 32

3.2.7.3.2 Versiheat

The Versiheat system uses a fan to redirect heat from the fireplace to an alternate room in the home. WARNING: To reduce temperatures above the fireplace for mounting a television the Versiheat system must always be on when the fireplace is in operation. Because the Versiheat system must be running to reduce temperatures the fireplace cannot be operated during a power outage. Testing has shown that when using two Versiheat systems temperatures above the fireplace are reduced making it possible to mount a television 15” above the fireplace’s top air gap.

Page 33

85-03-01115 DXV35 TIMBERFIRE Page 33

3.2.7.3.3 FlexHeat

The FlexHeat system uses two inline fans to redirect heat from the fireplace outside the home or to an alternate room in the home. WARNING: To reduce temperatures above the fireplace for mounting a television the FlexHeat system must always be on when the fireplace is in operation. Because the FLexHeat system must be running to reduce temperatures the fireplace cannot be operated during a power outage. Testing has shown that when using the FlexHeat system temperatures above the fireplace are reduced making it possible to mount a television 12” above the fireplace’s top air gap.

Venting

Th e DXV35 TIMBERFIRE Fireplace must be vented to the outside and mu st u se one of the approved coaxial rigid ducting systems or a coaxial flexible ductin g sy st em. Do Not Use any silicone sealants at pipe

joints. Stove gasket cements may be used at pipe joints but is not required .

The DXV35 TIMBERFIRE Fireplaces requires coaxial rigid- 4” diameter exhaust & 6-5/8” diameter air inlet and approved vent caps for most installations. In some special cases, flexible ducting may be used. Contact Mendota Technical Service Department if your installation requires other than standard rigid 4” X 6-5/8” Coaxial venting components. All UL Listed Coaxial Rigid 4”X6-5/8” Vent pipe components and vent caps are approved for use. Do not mix components of different brands or series. Always use the same brand and series components throughout the entire vent system.

All wa rranties will be voided and serious fire, health or oth er safety haz ards may result from any of the fol lo win g act ions: Installation by unauthorized personnel; installation of any damaged component; unauthorized modification of vent system; i nstallation of any co mpon ents not approved by Mendota; failure to meet all clearance requirements; failure to pro perly twist -lock and positively seal all components. Consult local building codes before beginning the installation .

WARN ING: Always maintain r equired cl earan ces (air spaces) to combustibles to prevent a fire hazard. Do not fill air spaces with insulation. Check installation in stru ction s for minimum clearance requirements between the outer walls of the vent pipe and nearby combustible surfaces . Be sure to ch eck the vent ter min ation clearance requirements from decks, windows, so ffit, ga s r egu lators, air supply inlets, and public wal kways, as specified in these installation instructions and loca l bui ldin g 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.

This gas appliance and vent system must be vented directly to th e outside of the building, and never attached to a chimney serving another solid fuel or ga s burn ing appliance. Each direct vent gas appliance must have its own separate vent system. Common vent sy st ems are proh ibited.

To a ssure proper venting per forman ce of this high-performance Mendota Direct Vent Fireplace, it is critical that all brand s of vent pipe sect ions are sealed tightly and leak -proof. This means that all pipe sect ions must be carefully rotated into the fully "twist -locked " po sition .

We strongly recommend that fixed length pipe sections be used in place of telescoping sections whenever possible.

COMPONENT "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 indentations so that they match and slide into the four entry slots on the male ends. 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.

Wall Heat Shield for Horizontal Vent Caps

Always use heat shield (#AA-11-00458) when the exterior wall covering is made of vinyl, wood or other combustible materials. Heat shield (#AA-11-00458) or an equivalent heat shield shall be installed. Heat shield (#AA-11-00458) is available for order directly from Mendota fireplaces.

Side by Side installation of two Vent Caps

When two or more vertical vent caps are located within proximity of one another, it is required that a galvanized steel 18-gauge or heavier barrier wall be installed between the two vent caps to eliminate recirculation of exhaust gases from one cap to another. The galvanized steel barrier shall be 6" taller than the highest point of the vent caps and shall be 3" wider past the outer edges of the vent caps. If two gravity direct vent system gas appliances are terminated next to each other, the minimum required distance between the vertical center line of the vent caps is 18” to prevent recirculation of exhaust from one vent cap outlet into the air intake of another vent cap. If a wood burning flue opening is adjacent to a gravity direct vent system gas appliance vent cap and the distance between vertical center lines of the two terminations is less than 36”, we recommend a metal divider plate be installed to prevent wood burning exhaust from entering the gas appliance air intake path. Alternatively, you may also vertically extend the wood burning flue liner up 24” higher than the top surface of the gas appliance vent cap.

Burner Ignition Characteristics

Note: Connect gas supply and verify that the mini mu m in let and outlet pressures are conforming. Once the conversion to LPG and all the above steps have been completed, light the main 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. Logs or coals must not block pilot flame or main burner flame. Vent system must be leak proof.

WARNING: Do not proceed with operation o f this firep lac e un less burner "cycles" on/off without delays!

Pilot Flame and Burner Relationship Verification

Prior to completing the LPG 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.

Th e pil ot light flames must be a min imum of 1” long and must overlap the propagation p orts on both the rear and front burner legs. Verify that the burner tubes ignite quickly and the burner flames pr opagate smoothly along the entire length of the burner.

Maximum Horizontal Run

❑ Maximum Horizontal Run allowed is 12 feet if a vertical starter section that is between 4 feet to 25 feet is connected

directly to this fireplace’s flue starter collar and no more than three (3) 90-degree elbows are used.

❑ Maximum Horizontal Run allowed is 12” if a 12” starter vertical section is connected directly to this fireplace’s flue

starter collar.

Maximum Vent System Length

❑ Combined total length of all straight pipe sections in the vent system shall be less than 55 feet. ❑ Combined total length of all straight pipe sections in the vent system shall be less than 55 feet when using three (3) 90-

degree elbows or equivalent and terminating the vent system horizontally.

How to Calculate the Vent Lengths

For calculation purposes and usage of charts in this manual, simply add the lengths of all individual straight pipe sections. For example: if you use two 2-foot lengths and one 4-foot length, the total vent system length will be 2+2+4 = 8 feet.

Using 900 Elbows

The DXV35 TIMBERFIRE Fireplace by MENDOTA allows maximum flexibility in the use of 90o elbows in the vent system. The length of the first straight vertical section directly connected to the fireplace’s starter collar determines the maximum horizontal run and the number of 900 elbows allowed for this fireplace. For vent systems that provide a starting vertical section that is 4’ to 25’, you may connect up to 12’ of horizontal pipe and up to three 90° elbows.

Using 90° Elbows When the Initial Starter Vertical Section Is Less Than 4’

For vent systems that provide a starting vertical section less than 4’ the following rules apply:

A. You must use the Master Venting Requirements Chart. B. A single 90° vertical-to-horizontal elbow is already calculated into the allowable maximum horizontal run. The Venting

Requirements Chart assumes that for all horizontal runs calculated, one 900 elbow is used within the venting system.

Note: Each additional 90° elbow reduces the maximum horizontal distance allowed by 3'.

C. If you plan to use more than one 90° elbow within the vent system, first use the Venting Requirements Chart and

calculate the maximum horizontal run you are allowed based on the first vertical section connected directly to the

fireplace. From this maximum horizontal run calculated, subtract 3’ for each additional 90° elbow you will use.

Caution: If a vertical-to-horizontal discharge elbow or a horizontal-to-horizontal discharge elbow is enclosed within a wall, floor or

ceiling, a top air space clearance of 2” must be maintained above the entire body of the elbow.

Using 45-Degree Elbows

Two 45-degree elbows may be used in place of one 90-degree elbow. On 45-degree runs, one foot of diagonal pipe is equal to 8-1/2 inches horizontal run and 8-1/2 inches vertical run. Two 45-degree elbows may be connected directly to the vent starter adapter on this fireplace to create an offset to provide the required clearances to combustible framing or sheathing materials.

Two 45-degree elbows may be connected directly to the top of this fireplace to create a horizontal offset. 12 feet maximum horizontal run allowed with this offset configuration only if the first vertical section connected directly to the last 45-degree elbow is more than 4 feet to 25 feet long. For maximum allowable horizontal distances with the 45-degree offsets, see the Master Venting Configuration Chart.

Note: Each horizontally positioned 45º elbow reduces the maximum horizontal distance by 1½ '. SUPPORT: Horizontal runs of pipe will require one vent support for every 3 ft. of pipe.

85-03-01115 DXV35 TIMBERFIRE Page 57

Minimum Rise Horizontal Termination

The minimum vertical section required to be connected directly to the starter adapter on this fireplace is 12”. With a 12” vertical starter section, a 6” horizontal run to a horizontal vent cap is allowed. If the total length of the vertical sections

connected directly to the starter adapter on this fireplace is between 4’ and 25’, you are allowed a maximum 12’ horizontal run. This fireplace provides a maximum flexibility in the use of 90° elbows when more than 4’ of vertical starter section is connected to the starter collar. If 4’ or more vertical section is connected to the starter collar, you may use three 90° elbows for horizontal terminations. For other venting configurations within these maximum limits, see Master Venting Chart.

Combined total length of all pipe sections in the vent system should be less than 44’. NOTE: The horizontal run of vent pipe mu st b e level o r have a ¼" rise for every 1' of run toward the ter min ation . Never allow the vent to run downward. This will cause h igh t emperatures and the possibility of a fire.

Follow these steps to install venting:

1. Position fireplace in desired location. 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 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.

3. Cut and frame a 9” wide x 10” high opening 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 have a ¼" rise per foot on horizontal runs 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 any floor (ceiling) opening.

4. The horizontal pipe must end flush with the exterior wall of the home. Horizontal pipe will require a proper support every 3’ of

vent pipe. There must be a minimum of 1" clearance to combustibles from all vent pieces on the sides and bottom and 2"

above horizontal runs.

5. A wall thimble must always be used when penetrating combustible wall materials.

6. Note: Combustible wall

thickness must be 4" to 8" maximum.

Note: Do not separate telescoping section. They be must be used as complete assemblies.

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 around the outer perimeter of the vent cap. Note: Vent cap shall not be recessed into wall or siding.

Figure 4-12 MINIMUM RISE HORIZONTAL VENT

85-03-01115 DXV35 TIMBERFIRE Page 58

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.

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 2" must be maintained above the elbow. Be sure to maintain 1" air space to any combustibles on the sides and bottom, 2" above horizontal pipe sections.

THI S FIREPLACE MUST BE INSTALLED BY A QUALIFIE D MENDOTA APPROVED SERVICEPERSON.

1. Position fireplace in desired location. 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 Be sure all vent components are properly twist locked and leakproof.

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 (2" above horizontal runs a nd above e lbows).

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.

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 2” above horizontal pipe sections and

components.

THI S FIREPLACE MUST BE INSTALLED B Y A QUALIFIED MENDOTA APPROVE D SERVICEPERSON.

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 2" 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. 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.

Vent Damper Adjustments

This fireplace is equipped with a vent damper system that can be adjusted. Locate damper adjustment rod above the glass

frame in convection chamber at the center. If this fireplace’s vent is terminated horizontally, DO NOT CLOSE the vent damper

completely. Adjust position of damper by judging the flame characteristics after 20 minutes of burn time. If the flames ghost off burners or if sooting occurs [in LPG units], open the vent damper FULLY and work backwards in increments to determine the correct damper position for that particular installation. Look into the convection air cavity and note the Damper Position Indicator. Loosen damper base screw. Turn counter-clockwise to close the vent damper, tighten screw.

If this fireplace’s vent is

terminated horizontally, DO NOT CLOSE the vent damper completely.

4.5 TIMBERFIRE LOG SET INSTALLATION

With door removed, proceed as follows:

1. Before placing log assembly in firebox, fill space under Log Grate with coals.

2. Follow the diagrams below in the sequence given. Start by identifying the Log Pins and Pin Hole in the Airbox. Next, identify

the log pieces according to the diagram below.

3. Place glowing embers (wool) sparsely on top coals, in front of front log. Additional wool may be rubbed on front surfaces of

log for additional glow. Add wool to "burned out" space between front logs. Fill area to back burner.

WARNING: Do not block holes with excessive wool. Delayed ignition and sooting can occur.

4. With glass removed, light pilot, and check for smooth ignition. Reinstall door, and check for smooth ignition. If any delay occurs,

make sure that no coals or wool is blocking pilot from front or rear burner holes.

5. Reinstall door, and check for smooth ignition again. If any delay occurs, make sure that no coals or wool is blocking pilot from

front or rear burner holes. Remove glass door, correct problem and repeat steps 4 and 5.

4.6 AIR SHUTTER CONTROL AND FLAME APPEARANCE

During initial installation, the air shutter opening should be checked to be certain that the shutter is set correctly at 1/8" open for natural gas and 1/2" minimum open for L.P. gas. NOTE: For altitudes above 5,000’, some variations may be required. Be sure burner and logs are properly installed. After log set has been properly installed, adjustments to the air shutter shall be made for final flame appearance. These small shutter adjustments can be made by the following procedure:

NOTE : All adjustments to the air shutter setting must be made by a qualified in sta ller, service agency, or the gas supplier. Very small changes in shutter settings mak e major changes in flame appearance.

The burner air shutter adjustment knob is located on the left side of the gas valve, below the spark ignitor button. Push the knob to

close the air shutter or pull on the knob to open the air shutter.

1. If flame is too blue, close air shutter in small 1/8"

increments until flame turns desired realistic yellow. Use glass latch tool to hook end and slide control.

2. If flame is causing soot on viewing glass, open air shutter fully until sooting stops. Continue burning unit with air

shutter fully open for four to six hours until all internal deposited soot has burned off.

3. Once deposited soot has disappeared, close air shutter in increments of 1/8”.

LPG Air shutter settings hint: A properly adjusted air shutt er sett ing will yield burner flames that have an approximate 2” high blue color base. If yellow colo red flames are starting at burner level, air shutter is clo sed too far and will create soot. If you observe that th e fla me is y ellow startin g very close to or at the burner surface level, open air shutter. Also, i f a log or part o f a log is susp ended and hanging inside a yellow portion of the flame, soot can form easily on th e p art of the log that is inside the yellow flame area.

IMPORTANT: Try each new shutter setting approx. ½ hr. before making additional change s. NOTE: Changes in fr ont burner flame can be made by re -arranging the coals and front bur ner air shutter opening.

4.7 LIGHTING CHECKLIST

Be sure to check these items before final operation of the Fireplace.

☐ All items on "Installation Checklist" must be completed. ☐ Carefully follow all lighting and log installation instructions. Make certain that pilot flame lights immediately and lights both

front and rear burners.

☐ Check for Gas leaks and gas pressures prior to installing facing materials. ☐ Air shutter opening 0" to ⅛" natural gas or ¼” to ½” LP gas is checked. ☐ All lighting and log installation instructions were followed. ☐ Burners light immediately and flame runs promptly around rear burner and lights entire burner.

Note: Do not proceed with operation unless burner cycles "on/off" without delays.

☐ 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.

☐ DO NOT proceed with operation unless burner cycles "on/off" without delays and the flame is "stable" and not "lifting" off

burner after 5 minutes of initial ignition.

Caution: If pilot goes out, be sure to wait a minimum of five minutes before relighting.

5.7 WHAT MAINTENANCE IS REQUIRED?

Required Annual Maintenance

The following procedures must be performed each year by a qualified installer, service agency or the gas supplier. Note: Any adjustments to burner, pilot or logs must be done by a qualified installer, service agency or the gas supplier. Recommended steps for yearly maintenance:

1. Clean all lint and dust build-up around the control. Inspect the condition of any wiring under the burner for melting or

damage.

2. Clean pilot thermocouple, thermopile and sparker rod using emery cloth. Vacuum clean pilot light assembly.

3. Visual check of pilot flames is required. Pilot flame must overlap thermocouple tip and burner ignition ports always.

Especially for LP gas applications, always verify visible pilot flame length is at least 1" long.

4. Vacuum all burner ports. Be sure the burner ports are "open".

5. Visual check of main burner’s rear and front flames is required.

6. Remove logs and coals and clean away any foreign matter (lint, carbon, etc.) on the burner and logs.

7. Clean under side of the logs for any carbon deposits. Note: Logs should be visually checked for carbon buildup. If carbon

deposits are visible on logs, unit should be turned off and a qualified installer, service agency or the gas supplier contacted. Be sure logs are re-installed per instructions.

8. Check condition of glass door gasket, gasket must seal tightly over firebox. Inspect gasket along top and sides of glass. If

gasket bulb along top edge or side top areas are discolored to a white color appearance (through the whole thickness of the gasket bulb in a 3” to 12” long area) and the gasket adhesive in no longer functional to stick to glass, then replace the gasket.

9. Visually inspect the vent terminal (vent cap) for leaves, twigs and other debris accumulation. Clean if required.

10. Clean door glass.

11. Clean enamel firebox lining, if one is installed.

Page 73

85-03-01115 DXV35 TIMBERFIRE Page 73

Periodic Inspection

Follow these steps for periodic inspections:

1. Check to verify that the vent system and vent cap are open and free of blockage.

2. Before re-installing glass, have qualified service person check the operation of the pilot and cycle the burner per lighting

instructions. Be sure all items in lighting and installation checklists are completed.

3. Periodic visual check of pilot flames is required. Pilot flame must overlap thermocouple tip and burner ignition ports

always. Especially for LP gas applications, always verify visible pilot flame length is at least 1" long.

4. Periodic visual check of main burner’s rear and front flames is required.

How do I clean the viewing glass?

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 a comparable product. Caution: Do not use oven cleaner to clean glass. Clean the glass only when it has cooled to room temperature.

Additives that are put in gas (both natural and p ropane) to make it smell can be harmful to glass and can lea ve a white fi lm deposit on the glass. This d epo sit can b e removed, if cleaned in a timely manner, with cleaners such as KEL KEM “Polish Plus” (part # 65 -06-0 04 55) or co mpar able product (contact your dealer).

Is my flame performance correct?

Your fireplace has air shutters, dampers, coals, and embers that can be adjusted depending on your fuel and venting configuration. These adjustments should be made by a qualified technician to achieve the best flame performance. Contact your installer or Mendota dealer if you feel your fireplace is not burning correctly. Improper setup and adjustment is not covered under warranty.

What should I do if my fireplace is sooting?

Sooting is caused by improper installation or air shutter operation. However, some small areas of soot deposits on log surfaces are deemed acceptable. If you observe large soot areas (larger than 1”x1”) 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), 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. Troubleshooting soot:

Issue: Thin black coating (soot) forms on viewing glass.

Possible Causes:

A. Burner Air Shutter closed too

much.

B. Exhaust Damper is closed too

much.

C. Improper log and/or ember

placement

D. Glass door seal is

compromised.

E. Incorrect gas pressure or

burner orifice size.

Corrective Action: Open air shutter on burner fully. Check exhaust damper position. It may be closed too far. Open exhaust damper. Check glass gasket for proper seal. Corners of glass gaskets cannot be bulging out. If glass gasket along top edge in the middle is white in color across entire thickness of gasket bulb and gasket adhesive is not functional, replace glass gasket. If sooting continues, shut off unit and call Mendota service person. Have service person check for proper Orifice Sizes and correct gas outlet pressure (3.5" W.C. Nat. Gas; 10" W.C. LP Gas). NOTE: To clean glass - remove glass and wipe glass with cloth or paper towel.

After completing these steps, contact your Mendota dealer if fireplace won’t turn on.

What happens when I first light my fireplace?

When you first light your fireplace, the initial curing phase is initiated. During the initial curing phase, a small amount of smoke and odor will be emitted. This is normal. To complete the curing process, run your fireplace, on high fire, for two hours with the fans on level 3. Open doors and windows to dissipate any odor. Turn your fireplace off. After it has cooled, run it again, on high fire, with the blowers off until no smoking or odor remains. Refer to Chapter 3.1.1 Mendota Fireplace Curing Instructions for more information.

MAINTENANCE INFORMATION

6.1 REQUIRED PERIODIC INSPECTIONS

1. Check to verify that the vent system and vent cap are open and free of blockage.

2. Have qualified service person check the operation of the pilot light. Pilot light must light within the first five to eight

seconds of ignitor sparks initiation. If it takes more ten seconds to ignite the pilot flame, check pilot spark rod position and ignitor wires for pinched areas or damaged areas.

3. Periodic visual check of pilot flames is required. Pilot Flame

must overlap thermocouple tip and burner ignition ports always. Especially for LPG applications, always verify visible pilot flame length is at least 1" long, minimum.

4. Cycle the burners to make certain burner ignition is prompt

and flame propagation along burner length is quick and smooth. If flame propagation is delayed, remove obstructing debris, vacuum burner ports and retry.

5. Periodic visual check of rear and front burner flames pattern

is required.

6.2 CLEANING VIEWING GLASS

WARN ING: Do not clean when glass is hot.

The viewing glass should be cleaned periodically. Exterior glass surface may be cleaned with cleaner as desired. To clean Interior glass surface, remove glass frame assembly.

85-03-01115 DXV35 TIMBERFIRE Page 75

. Use Kel Kem “polish plus" (part # 65-06-00455) or comparable product to clean glass interior surface. Do not use oven cleaner or abrasive cleaners to clean glass.

6.3 REQUIRED ANNUAL MAINTENANCE

See Chapter 5.7 What maintenance is required? In addition to the “Required Periodic Inspection s” , the fol lo win g pro cedures m ust be performed each year by a qualified installer, service agency or the gas supplier . Any adju st ments to burner, pilot or logs must be

done by a qualified installer, service agency, or the gas supplier . Clean all lint and dust build-up around the control and blowers. Inspect the condition of any wiring under the burner for melting

or damage. Clean thermocouple and thermopile tips using emery cloth. Vacuum all burner ports and pilot assembly. 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 heavy carbon deposits are visible on logs, unit should be turned off and a qualified installer, service agency, or the ga s supplier should b e contacted. Be su re log s are re-installed per instr uctions.

85-03-01115 DXV35 TIMBERFIRE Page 76

6.4 OVER FIRING OR UNDER FIRING OF BURNER

NEVER "over fire" or “under-fire” units by increasing or decreasing the main orifice sizes or by adjusting gas pressure to increase BTUH above nameplate specifications.

Over fi rin g can cause permanent damage to firebox and deterioration o f pa rts and void the warranty. Under-firing can potentially cause delayed ignition and lead to property loss and person injury and will void the warranty.

If you a re using a “backyard” Natural Gas well as t he ga s so urce, you must submit formal gas analysis data

sh eet s to Mendota Fireplaces for review and calculation of prop er main burner orifice sizes prior to first fir ing. It is known that unpurified Natural Gas from “backyard” wells can contain high energy levels ca using over firing. Further, unpurified gas can contain high levels of Sulphur and other compounds which can damage the burner materials and the ceramic gla ss. Use o f unpur if ied gas will void the warranty for this product.

6.5 PILOT OUTAGE AND RE-LIGHTING

If pi lot goes out, be sure to wait a minimu m o f five minutes before attempting to re -light. If lockout occu rs frequently, contact you Mendota Dealer for diagnosing th e pr oblem.

Frequent lockout can be caused by many factors and must be properly diagnosed, and the primary cause identified. It should never be assumed that the ignition control system is faulty without proper diagnosis.

6.6 BURNER FLAME HEIGHTS REFERENCE DIAGRAM

Figure 6-2 Burner Flame Heights: This image provides a visual reference for the burner flames burning at maximum height after the burners have been operating for 30 minutes or longer. A normal rear flame will be 1 to 2 inches above the rear log top edge. This, however, is dependent on the gas type, air shutter opening setting and vent system configuration. Actual flame heights can be slightly higher or lower when compared to this reference image.

6.7 REPLACEMENT PARTS INFORMATION

How to Access Components

The descriptions below show where the main fireplaces components are located and how to access them for service. The descriptions show how to access the components after the fireplace has been installed. All components are also accessible from the outside of the unit before the fireplace is installed.

Pilot: The pilot light is located on the right side the firebox to the right ends of the burners. Gas Valve: The main gas valve is located behind the lower grill and beneath the firebox. Complete Valve Assembly: To make working on components easier, this fireplace has been designed with the valve, pilot,

shutter boxes, shutter cables and gas lines as part of one assembly that can be removed from the fireplace. To remove the assembly, first remove burners and burner airbox. After disconnecting the gas line and wires, below the firebox, remove hex nuts that secure the valve mounting plate to firebox floor. Lift up and remove the entire assembly from the firebox.
