READ ME FIRST

1.1 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 insert. See chapter 3.1.1 Mendota Fireplace insert 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 insert, odors will slowly dissipate and disappear.

ODOR RISKS

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

1.2 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 insert 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.

WARNING: The supplied barrier screen must be installed , always, when this fireplace insert is in
operation. Do not place any object directly in front (within 60”) or directly above (on the front edge
of the mantel). This is a heating appliance. Areas directly in front and above this appliance will be
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.

1.3 PERIODIC AND ANNUAL CLEANING ARE REQUIRED

See Required Periodic Inspections, Chapter 6.1 and Required Annual Maintenance, Chapter 6.4. Periodic and Annual
cleaning and general services are required at least once a year in the Summer or early Fall. Cleaning 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 burner s, perform the following inspections 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 insert, 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 insert to cool. Proceed with Mendota Fireplace insert Curing

Instructions, Chapter 3.1.1.

This fireplace insert 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

insert.
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 insert glass door and will increase flue draft during
startups.

WARNING

FIRE RISK/ODOR RISK

• An R-1 Rated Hearth Protection Pad, 16” deep, is required unless this fireplace insert is elevated at least 6” above

floor level of the room. For every 1” this fireplace insert is elevated, you may reduce the hearth pad depth by 2”.

Locate and install appliance to all clearance specifications in manual.

• Verify glass gasket seal before firing unit the first time. Verify proper latching of glass frame onto unit body.

• Understand that this appliance requires a break-in period during which small amounts of smoke and curing smells

will be emitted.

Mendota Fireplace insert Curing Instructions

ATTENTION

It is important that the blowers are turned on during this step to prevent the curing smoke from staining the
wal l finish above the fireplace in sert. Mendota recommends completing Step 1 prior to install ation of wall
finish materials.

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 home
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 insert on.

• Set the Flame Height to Hi.

• Set the Fan Speed Control to medium.

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

• Turn the fireplace insert off and let it cool.

Step 2: High Heat Curing Cycle

• Turn the fireplace insert on.

• Set the Flame Height to Hi.

• Set the Fan Speed Control to Off.

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

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

Step 3: Final Curing Cycle

• With the fireplace insert still turned on from Step 2.

• Set the Fan Speed Control to the lowest setting.

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

diminished.

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

fireplace insert is used.

Additional Curing Information

It is not unusual for a fireplace insert 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 insert are subject to high temperatures. Finishing materials used over the fireplace insert
in the non-combustible zone can see temperatures around 350° F. Materials used around the fireplace insert must be rated for
these temperatures. Failure to use adequate materials can result in odor problems. Please refer to Chapter 3.2.5 of this manual
for information on appropriate finishing materials.
Please be aware that materials used around the fireplace insert 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 insert.

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

Note: For every 1” this fireplace insert is raised off the floor, the non-combustible hearth protection pad may be
reduced by 2”. If this fireplace insert is raised more than 6” off the floor, no hearth protection pad is required. See

Chapter 3.2.4.4 Hearth Pad Requirement and Chapter 3.2.7.1 Hearth Pad Temperatures.

85-03-01071 D30 DEEP TIMBER Page 20

Hearth Pad Requirement

A non-combustible hearth protector with a thermal insulation rating of R-1 is required when installing this fireplace insert
directly on the floor and must extend a minimum of 16" in front of the fireplace insert.

For every 1” the fireplace insert is raised off the floor, the depth of the required hearth protector may be
redu ced by 2”. If fireplace in sert is raised off the floor 6" or more, no hearth protector is required for fire

protection.
Pre-existing non-combustible hearth pads are approved. New hearth pads installed are required to have a thermal insulation

value of R-1.
Caution: The fireplace insert creates localized heat and causes thermal expansion of adjacently installed

floo ring and wall materials . Vinyl floors and floating Engineered wood floo rs may warp if installed in front
of th is unit even when th is fireplace insert is raised 6” or more due to local heating up of t he floor
mat erials. Never use vinyl or Engineered wood flooring in the hearth pad area in front of this fireplace
insert unless you plan to raise this unit 12” or more above the f loor 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 possible to prevent radiation ef fects to the
carpet fibers even when this un it is raised high. Avoid installing carpets in the hearth pad area in front of
this Fireplace insert unless this fireplace insert is raised at least 12 inches above the carpet level .

Re-facing a Woodburning Fireplace insert

Remodeling an old wood burning fireplace insert and its surrounding wall facings is a cost-effective way to modernize and
enhance the beauty of a home and to raise the resale value of a home. This form of remodeling is called “re-facing”.

Notes for re-facing:

1. All re-facing framing members’ material within 24” of the opening of the existing wood burning fireplace insert must be

galvanized steel.

2. Directly above the top of the existing wood fireplace insert, a galvanized steel stud must run horizontally across the

opening of the fireplace insert. On the bottom face of this horizontal galvanized steel stud, a heat rise barrier made from ½”
thick noncombustible mineral board must be installed in a manner which completely blocks heat from seeping and rising
upwards between the existing wall face and the newly installed wall surface structure.

Warning: Failure to install this Heat Rise Barrier board can lead to a fire hazard.

3. All facing materials used on the new framed structure and within 24” of the existing fireplace insert opening, in all four

directions, must be of the noncombustible type. See 3.2.8.3 Suitable Finishing Materials R-Ratings, for recommended

suitable facing materials.
Note: The suggestions given in this section are Mendota Fireplace insert’s recommendations only. All local
buildin g code requirements must still be researched and followed.

Figure 3-15 Re-facing Information

85-03-01071 D30 DEEP TIMBER Page 22

Clearances to Combustible Side Walls

The minimum distance required from the
side edge of the glass frame to a
combustible side wall is 16” (14” from the
side edge of this appliance). Combustible
side walls, mantel corbels, mantel legs and
other combustible walls and decorative
objects must fall behind a 45-degree line
extending outward from the side edges of
the visible glass unless such objects are
more than 16” away from the side edges of
the glass frame.

A wall, perpendicular and in front of this
appliance's glass door face must be at least
16" 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-existin g combustible side wal l, an NFPA approved clearance
redu ction shield, metal or ceramic board, must be added to the side wall.

3.2.6.1.1 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.

3.2.6.1.2 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 insert is in
operation. Do not place any object directly in front (within 60” from barrier screen surface ) or directly
above (on the front edge of the mantel). This is a heating appliance. Areas directly in front and above this
appliance will be very hot and can damage most household objects if placed too clo se. Keep Furniture
pieces at least 60” away in front of the barrier screen surface.

HINT: To greatly reduce surface temperatures su rrounding this Fireplace insert during operation, Mendota
recommends operating the integrated convection air blowers which aid in cooling all surroundin g surfaces.

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

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 insert 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 insert can be very
hot (too hot to touch, exceeding 250oF) and is deemed
normal.

Mantel Temperatures

Mendota Fireplace inserts comply with ANSI Z21.88­2016 standards for maximum surface temperatures on

exposed “combustible” surfaces adjacent to the

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

Suitable Mantel, Facing & Hearth Pad Materials

Use of ceramic glazed tiles as facing materials around a Mendota Fireplace insert 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 insert. If using RTV silicone, allow a minimum 48 hours cure time for the silicone to cure before firing this Fireplace
insert after tile application.

Figure 3-17 Hot Zones

85-03-01071 D30 DEEP TIMBER Page 24

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 natural stone that is water jet or mechanically cut in a U-shape
as facing material to cover the sides and top areas around this product. Doing so can lead to crack
formation at the inner corners of the U shape due to thermal expansion.

Figure 3-18 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 polyester resin used on marble slabs can discolor when exposed to temperatures greater than 150oF
and will structurally fail at temperatures above 2 30oF. The epoxy resin coating used on granite slabs are
resistant to discoloring and structural failures up to 3 50oF.Mendota does not assume any liability for
discoloring, flaking or cracking of marble or granite.

Temperatures on facings around Mendota Gas Fireplace inserts
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 insert cannot guarantee suitability
of u se of any marble slabs or tiles that have a
polyester resin coating applied to it and cannot
guarantee against discoloration or structural failure of
marb le or polished stone facings that have a polyester
resin coating. Consult 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 bar e marble and bare stone 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 Fireplace inserts.
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

3.2.8.4.1 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 insert 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.

3.2.8.4.2 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 insert, 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.

3.2.8.4.3 Wood Application Cautions

If wood used around or in front of the fireplace insert 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 insert,
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.

85-03-01071 D30 DEEP TIMBER Page 28

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.

85-03-01071 D30 DEEP TIMBER Page 29

Venting

Th e D30 Insert must be vented vertically to the outside and must use one of the approved co -linear flexible
ducting systems or a coaxial flexible ducting system. Mendota recommends that both exhaust and air intake
flex liners be run all the way to the vent cap. Seals between flex liners and unit top and ven t cap must be
permanent and as air tight as possib le. Do Not Use any silicone sealants at flex pipe joints. Stove gasket

cements may be used at pipe joints but is not required . Do use both securing screws and hose clamps

at all four flex connection points.

Maximum and Minimum Vent Lengths

Minimum vent run length required is 10’. Maximum vent run

allowed is 50’. Only vertical terminations are allowed. No
horizontal runs are allowed within the vent system. Horizontal

offsets of less than 4’ are approved if the offset is angled at

least 30-degrees vertically.

Run Liners to Vent Cap

When existing wood burning chimney size allows, run both the
4” exhaust liner and 4” air intake liner to the vertical vent cap.
If existing wood burning chimney size is too small to run both

4” and 4” liners, consider converting to a coaxial flex system
using a 4” exhaust flex and 6” air intake flex with spring

spacers between the two flex pipes or converting to a B-Vent
single liner system.

Air Intake Liner Stubbing

When existing wood burning chimney, size is too small to run
both 4” and 4” colinear liners, it is an option to use the Coaxial
Vent Kit or to cut the air intake flexible duct short and run only

the 4” vent flexible duct to the vent cap connector. This is
generally called “stubbing”. However, understand that doing

so may lead to venting problems when weather storms
approach. Variations between the air pressure inside the home
and atmospheric air pressures outside the home can cause

venting problems and performance failures. Avoid “stubbing” if

chimney flue size allows installation of both liners fully to the vent cap; or consider using a coaxial vent system, instead.

MENDOTA RECOMMENDED VENT COMPONENTS AND VENT KITS LIST

Fireplace insert and Chimney Cleaning Requirements

The plan to install a gas fireplace Insert must include inspection and cleaning of the fireplace insert cavity and the entire
chimney system. The chimney top, especially masonry chimneys and wood framed chimney tops must be inspected and the top
surface must be repaired or replaced, if necessary. Unlined chimney flues are the most vulnerable to mortar corrosion and
damage. These flues must be inspected and repair must be done before dropping the flex vent liner for this Insert.

If you encounter a badly deteriorated or completely damaged firebox, do not proceed. These damaged structures must be
reviewed by structural Engineers and Local Building Code officials must approve the repair work prior to this Insert being
installed in such a damaged cavity.

Mendota requires that the fireplace insert cavity and chimney system be cleaned per the Chimney Safety
Inst itute of America recommendation prior to installation of a Mendota gas fired Insert. The Chimney

Safety Institute of America recommends that open masonry fireplace inserts should be swept at 1/8" of
sooty buildup, and sooner if there is any glaz e present in the system. This is consid ered to be enough fuel
buildup to cause a chimney fire capable of dama ging the chimney or spreading to the ho me. Factory -built
fir eplace inserts should be swept when any appreciable buildup occurs. The logic is that the deposit is quite
acidic and can shorten the life of the fireplace insert.

Figure 3-21 Damaged Chimney Cap

Figure 3-22 Unlined Flue

Figure 3-23 Badly Deteriorated
Firebox

WARNING: Failure to inspect and repair or replac e damaged or dilapidated chimney flue, firebox or
chimney top caps can lead to odor emissions, water penetration and damage to electronic components of
this gas Insert or damage to other home structures. This omission to inspect, repair or replace as
necessary will void all applicable warranties on th is product.

Types of Chimney Flues

Chimney flues can vary in shape, size and type. During inspection, make note of the type of the flue system used. Professionally
clean and make any repairs before installing a Mendota gas Insert. Especially, pay attention to unlined flues which may have
missing or severely damaged mortar joints.

Figure 3-24 Clay Tile Liner Flue

Figure 3-25 Unlined Flue

85-03-01071 D30 DEEP TIMBER Page 31

Types of Chimney Tops and Vent Caps

Chimney tops vary in shape and size and configuration. The vent cap selected for installation will require some modification to
fit various chimney top types. Consult with your vent supplier.

Figure 3-31 Concrete Cap Chimney
Top

For installation of this Insert’s vent cap with chimneys that have an existing metal, stone or concrete cap
(Figure 3-29, Figure 3-30, Figure 3-31), Do Not use “low profile” vent caps. They are vulnerable to exhaust
recirculation and ghosting flames problems. Always use full size vent caps and allow a minimum 3”
clearance from vent cap top to the chimney cap. For wider chimney caps and slabs, greater than 16” wide,
increase the clearance above the vent cap to 6” minimum. If necessary, raise the slab to supply the required

clearance.

85-03-01071 D30 DEEP TIMBER Page 32

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.

Decorative Cover for Vent Cap

It is acceptable to install a decorative stone, metal or terra cotta cover to disguise the vent terminal/cap used on Mendota
Inserts if the decorative cover meets the following minimum requirements:

1. The decorative cover shall be manufactured from noncombustible materials.

2. The decorative cover shall provide a minimum of 3” clearance from the outer surface of the vent cap to the inner walls

of the decorative cover on sides all of the vent cap.

3. Fresh air openings shall be provided at a level equal to or below the fresh air openings in the vent cap. The fresh air

openings shall provide a minimum open area of 60 square inches. This fresh air opening area shall be broken into at
least two equal openings (or more if possible). Each opening shall have a minimum height of 2” and a length that
provides the required opening to yield a total of 60 square inches, minimum.

4. The fresh air openings shall be protected in a manner that prevents the accumulation of snow which can plug the fresh

air openings.

3.3 ELECTRICAL TECHNICAL REFERENCES

AC Power Requirements

WARNING: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous
operation. Verify proper operation after servicing.

For blower operation, 120 VAC, a 2 Amp power source is required. The AC power supply to this Fireplace
insert must be hot at all times and shall not have a switch installed in it.

This appliance is equipped with an electrical junction box on the left side.

1. Place connected wire ends within junction box then close and secure the junction box cover plate.

AC Power Connection Option

Two options exist for supplying 120 VAC power to this appliance:

1. Run the 8-foot extension cord connected to the blower circuit out of

the fireplace insert cavity to a wall electrical outlet in the room.

2. Install an electrical outlet (inside a metal junction box with metal

faceplate) inside the wood burning fireplace insert cavity.
Always use metal flex conduit encapsulated 14-2 cable

(MC Cable) to run power from the source to th e outlet
junction box. Installation of the electrical outlet and its
elect rical supply cable must conform to all local electrical
code requirements.

3. For this application, roll the 8’ extension cord in a tight loop and

place the loop inside the lower convection chamber of this
appliance. Plug the extension cord’s 3-prong plug into the newly
installed junction box.

Notice: Mendota wants to make you aware o f current NEC
Codes that may be enforced by local authorities. Mend ota
cannot over-ride local building officials’ en forcement of
National Electrical Codes. Be aware of these potential
requirements.

Notice: Electricity circuits cannot be shared between different
floo rs within a home. This means that you can run a power
cable from a basement to the main floor fireplace insert th rough an ash cleanout opening or by d rilling a
hole through. However, you cannot tap the power directly from a power circuit in the basement that
supplies power to basement lights or outlets. You must run a dedicated power circuit from the main fuse
panel to the upper level fireplace insert

Notice: An MC Cable which enters an electrical jun ction box must employ a strain relief clamp at th e entry
point permanently to prevent movement, vibration and disc onnection or loosening of electrical connections
inside the Junction Box. Not using a strain r eli ef clamp can lead to arcing between loose connections and
pose a fire hazard. If an outlet is installed inside a wood burning fireplace insert always use a metal junctio n
box, MC Cable and strain relief clamps.

How to Run Gas Line to Insert Location

Caution: Before you run the gas line, read, understand and properly calculate the required gas line size.
Impr oper (too small) gas line size application can lead to improper burner ignition and can cause p roperty
damage and/or injury. If you are not qualified or certified to run a gas line, do not proceed. Contact a
qualified Gas Plumber.

Note: If the factory-built fireplace insert has no gas access hole(s) provided, an access hole of 1.5 in (37.5
mm) or less may be drilled through the lower sides or bottom of the firebox in a proper workmanship -like
manner. This access hole must be plugged with non -combustible insulation after the gas supply line has
been installed.

It is recommended that you run the main gas supply line end to the left side of the wood burning fireplace insert cavity. The gas
valve and flexible gas connector supplied with this fireplace Insert will exit at the rear wall left edge or the left wall rear edge,
when facing this unit. See Figure 3-39
The factory supplied flexible gas connector is 4’ long and provides 32” of loose flex outside the Insert body. Create a vertical
flexible loop with the excess flex connector length so it aids in pushing the unit into the cavity without damage to the flex
connector and aids in preventing damage when Insert is pulled out during service work.

Gas Inlet Fittings Information

Caution: Before you run the gas line, read, understand and
properly calculate the required gas line size. Impr oper (too
small) gas line size application can lead to improper burner
ignition and can cause property damage and /or injury. I f you
are n ot qualified or certified to run a gas lin e, do not
proceed. Contact a qualified Gas Plumber.

The gas inlet fitting supplied with this Fireplace insert provides a 1/2”
male NPT fitting. This requires you to supply a 1/2” NPT female fitting
for connection to this appliance.

4.3 LEVELING BOLTS

Leveling Bolts Definition

Four leveling bolts are included in the manual package. The leveling bolts allow for a ¼” minimum to 2” maximum leveling

ability. Leveling bolts are designed to adjust for uneven fireplace insert floors and yield plumb Insert Body. Use the leveling
bolts only if the fireplace insert floor is more than ¼” out of level from one side to another or from front to back. If the fireplace
insert floor is less than ¼” out of level, use metal sheet shims in various thickness and build up to needed leveling thicknesses at
various points around the appliance.
The leveling bolts supplied are designed specifically for application with this product. only use leveling bolts supplied by
Mendota and for leveling purposes only. Never use leveling bolts for purposes of lifting unit up to make up for ash lip heights or
other lifting or raising needs. Such use can cause extreme thermal expansion of firebox floor and can result in oil canning noise
or louder thermal expansion and constriction banging noise. SUCH NOISE PROBLEMS ARE NOT COVERED UNDER

MENDOTA WARRANTY

Note: When lifting this Insert more than 1”, other support blocks will be required. For all applications when
you raise the unit more than 1”, reline the entire firebox floor with refr actory brick s to build up a full level

floo r for the Insert to sit on. Do not use individual support block only under the four corners of th is unit.
WARN ING: Failure to position the parts in a ccordance with these diagrams or failure to use only parts

sp ecifically approved with this appliance may result in property damage or personal injury. Never use other
aft er-market leveling bolts. Doing so can lead to vibration noise problems or damage to internal
components.DO NOT USE LONGER BOLTS TO LIFT INSERT UPWAR D. THIS CAN CAUSE O THER SIDE EFFECTS
LIKE HEAT EXPANSION/CONTRACTION NOISES. To lift Insert up, use Firebricks and mortar or a metal box
design ed specifically for this purpose.

Leveling Bolts Installation

Perform this step after you have measured the firebox floor for level surface characteristics. Tip the Insert body on its back on
the wooden pallet. Thread one leveling bolt in to each leveling bolt receiving fastener. Thread the bolt in as far as necessary to
achieve the leveling effect desired.

WARN ING: Failure to position the parts in a ccorda nce with these diagrams or failure to u se only parts
sp ecifically approved with this appliance may result in property damage or personal injury.

A natural gas to LP gas conversion kit #HA-28-00194 must be ordered and installed in this fireplace insert to burn LP gas.

LP conversion kit #HA-28-00194 contains the following parts: one manual LP pressure regulator, one cap orifice #52, a bell­shaped Pilot LP Orifice and an LP conversion label.

Procedure to Convert Fireplace insert for LP Gas

This fireplace insert arrives from the factory ready to burn natural gas. If you intend to burn LP gas, you must convert this
fireplace insert and its pressure regulator, pilot orifice and burner orifices prior to placing this fireplace insert in its fireplace
insert cavity.
Follow the step below to prepare this fireplace insert for conversion to LP gas:

1. Shut off the gas supply to the valve and shut down the electric supply.

Note: Be careful when removing or tightening the screw on the pressure regulator. Care must be taken to ensure a proper seal

when tightened.

2. Install orifice #65-14-00052 (#52 drill) as the Main Burner Orifice.

Orifice is removed and installed with a ½” deep well socket and ratchet.

3. While holding the pilot base body with large vice grips tightly, loosen the pilot’s hex-shaped base using a 7/16” open

end wrench. Rotate counter clock-wise to loosen. Remove pilot hood and NG pilot orifice. Pilot orifice thimble is
located inside pilot hood base.

4. Install LP pilot orifice #05-04-00036 (.014”). Replace pilot hood and tighten.

CAUTION: Always use one 7/16” open end wrench and one large pliers or vice grips tool to hold, loosen and
tighten pilot hood base to prevent damage to pilot mount bracket.

Figure 4-7 Pilot Orifice Access

85-03-01071 D30 DEEP TIMBER Page 47

6. Install the airbox and the burner in their original

locations and positions and secure down using screws
you removed earlier.

Next, the pressure regulator will be changed.

7. Using a ¼” flat blade screwdriver, remove 3 screws

that secure the NG Pressure Regulator to the gas
valve body and remove NG Pressure Regulator as
shown above. Identify the pressure regulator spring
that is located in the center of the black rubber
gasket. Discard both the black rubber gasket and
spring.

8. Install the new LP Pressure Regular onto the gas valve

body in the same position and orientation as the NG
Pressure Regulator you removed in Step 2, above.
The LP Pressure Regulator can only be mounted in
one position. Secure the LP Pressure Regulator in
place using the 3 screws you removed in Step 2.
Tighten down using a ¼” flat blade screwdriver.

Burner Ignition Characteristics

Note: Connect gas supply and verify that the min imum inlet and outlet pressures ar e 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.

WARN ING: Do not proceed with operation o f this fireplace insert unless burner "cy cles" on/off without
delay s!

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 pilot light flames must be a minimum of 1” long and must overlap the propagation ports on both the

rear and front burner legs. Verify that the burner tubes ignit e quickly and the burner flames propagate
smoothly along the entire length of the burner.

4.6 VENTING

WARN ING: Proper installation of the vent system, as required in this manual, is vital to the perfo rmance of
this Insert. Oversights or failure to conform to all installation requir ements will void the applicable
war ranty.

Th e D30 Insert must be vented vertically to the outside and must use an approved colinear flexible ducting
sy stems or a coaxial flexible ducting system.

This heater must be properly connected to a venting system in accordan ce with the manufacturer's
inst allation instructions. Operation of thi s heater when not connected to a properly installed and
main tained venting system can result in carbon monoxide (CO) poisoning and possibly dea th.

If th e vent system of this appliance is disconnected for any reason, the vent and air intake systems must be
properly reassembled and resealed before this appliance is put into u se.

When existing wood burning chimney size allows, run both the 4” exhaust liner and 4” air intake liner to the vertical vent cap. If
existing wood burning chimney size is too small to run both 4” and 3” liners, consider converting to a coaxial flex system using a
4” exhaust flex and 6” air intake flex with spring spacers between the two flex pipes.

NOTE: Mendota recommends that both exhaust and air intake flex lin ers be ru n all the way to the vent cap.
Sea ls between flex liners and unit top and vent cap must be permanent and as air tight as possible. Never use
si licone sealants in pipe joints. U se of sealants at flex pipe joints is not required. Do use both securing
sc rews and hose clamps at all four flex connection points.

When existing wood burning chimney flue size is too small to run both 4” and 4” liners, it is an option to cut the air intake

flexible duct short and run only the 4” vent flexible duct to the vent cap connector. This is generally called “stubbing”. However,

understand that doing so may lead to venting problems. Variations between the air pressure inside the home and atmospheric
air pressures outside the home can cause venting problems and
performance failures.

CAUTION: Each installation must conform to all local,
stat e and national codes. Refer to the national fuel gas
code and local zoning and code authorities for details on
inst allation requirements. The Mendota Inserts must be
vented to the outside in accordance with the lat est
edit ion of the National Fuel Gas Cod e. In the absence of
loca l codes, the installation must conform with National
Fuel Gas Code ANSI Z223.1 (NFPA 54), or Canadian Code
CAN 1-B149 or most current edition, also known as NFPA

54. Do not connect this Insert to a chi mney fl ue serving
a separate solid fuel or gas-burning appliance.

Figure 4-9 Vent System

85-03-01071 D30 DEEP TIMBER Page 49

Dropping Flex Vent Liners

Figure 4-10 Installing Flex Liners

1. Measure the chimney height from the top of the chimney (or the existing flue liner) to a point 12" (300 mm) above the

floor of the fireplace insert hearth. It may be necessary to drop a rope and measure the rope itself. Be sure to allow for
all offsets in existing chimney. Cut the 4" diameter flex liners to this measured length.

2. Attach a sheet metal strap loop to the flex end of the liner(s) and tie a rope to it. Two installers should proceed to the

roof and drop the rope (with weight on the end to make sure it goes all the way down) and insert the 4” liners past the
flexible portion, into the existing chimney.

3. One installer should then return to the fireplace insert opening and pull the rope to guide the liner(s) into place

through the smoke shelf and the damper opening to a point 12" (300 mm) above the fireplace insert hearth. The
person below should wear leather gloves and Safety Glasses during this process to avoid being cut and to safeguard
eyes from flying debris.

Sock Gasket Installation

See Figures, below. The Round Sock Gasket (Woven White Fiberglass Material) is required to be assembled on the Sock Gasket
Plate (Metal Ring- Donut Shaped) as shown, below.

The Sock Gasket and the Sock Gasket Plate Assembly create the seal between the Fireplace Insert Firebox and the Vent Adapter
Box. This gasket assembly must be installed as depicted in these instructions.

WARN ING: FAILURE TO INSTALL THE SOCK GASKET PROPERLY WILL RESULT IN SOOTING, GHOSTING AND
UNACCEPTABLE FLAME APPEARANCE DUE TO EXHAUST GASES RECIRCULATING BACK INTO THE FIRE BOX
TH ROUGH THE COMBUSTION AIR INTAKE PA THS.

Vent Adapter Installation Instructions

1. Prior to sliding Insert into Fireplace insert Cavity, attach the Vent Adapter Box (Colinear or Coaxial, depending on your

selection) to the two 4” flex pipes [or the 4” and 6” coaxial liners] you dropped down the chimney. Secure the flexible pipes

to the Vent adapter starter collars using hose clamps and 4 equally spaced self-drilling screws. Create a proper airtight seal
at both pipe connection joints.

2. Remove the ceiling baffle from inside the firebox. Remove two ¼” Hex Hd. Screws that secure the baffle to the firebox ceiling,

then slide the baffle out of the firebox.

3. Slide Insert into Fireplace insert Cavity and position it in its approximate final position. From inside the firebox, reach through

the 4” hole on firebox ceiling and Slide the Vent adapter through Sock Gasket Assembly then slide this assembly through the
4” hole on firebox top. Sock Gasket must contact firebox top’s outer surface.

4. From inside the Firebox, center the Vent Adapter Assembly within the 4” hole at the firebox top. NOTE: THIS IS CRITICAL. IF

NOT CENTERED, AN EXHAUST LEAK CAN OCCUR!

5. See Figure, below. Slide Adapter Bolt through U-Clamp’s center hole. U-Clamp must face upward. Hold the Vent Adapter

against the firebox top. Hand thread U-Clamp Nut then tighten U-Clamp Nut using a ½” open-end wrench or a ½” deep-well
socket and ratchet. Tighten the nut enough to compress the sock gasket ½ its thickness and create a proper seal. Do not
over tighten, as doing so can permanently damage the vent adapter.

6. Reinstall the baffle in its original position and secure in place using the two hex head screws you removed earlier.

Attaching Flue Liners to Vent Cap

Four hose clamps are supplied with each Mendota vent kit. Four
#8 sheet metal screws are needed which are not supplied with
Mendota vent kits.
For vent kits (other brands) obtained from other distributors or

suppliers, acquire four 4” diameter hose clamps and eight #8

sheet metal screws. Follow these procedures to secure the
flexible 4” liners to the Insert Top vent adapter and the vent cap
starter collars:

CAUTION: Always inspect flex liners for tear s and
punctures. If any tears or punctures are found, d o not
use the liner. Replace the liner with a new one.

Make certain vent cap/ flashing is permanently sealed to chimney
top using exterior grade roofing sealants.

1. At the chimney top, attach 4” flex vent to the 4” exhaust

starter collar on vent cap.

2. Secure the 4” vent flex to the 4” exhaust starter collar

employing one 4” hose clamp and a ratchet. Position hose clamp close to the flashing plate. Compress the flex as much as

possible around the starter collar to obtain a tight joint between starter stubs and flex inner surface.

3. Secure the flex liner to the starter collar with sheet metal screws in two equally spaced radial locations and below the hose

clamp to stop hose clamp from sliding off.

4. Repeat this procedure for the air intake flex liner.

Sealing the vent cap base plate or flashing to the Chimney Top

Note: It is required that the chimney -top be permanently sealed to prevent cold air and water infiltration
into the home.

The vent cap base plate of a square shaped vent cap or the base plate of a co-linear to coaxial vent adapter (chimney top
adapter) must be sealed air tight and permanently to the existing chimney top.
To seal to the top of a chimney, follow these steps:

1. Trim the base plate of the vent cap or vent adapter to size and shape desired.
a. To seal on top a large flat surface, trim the base plate as desired but allow a minimum of 1” overlap outside the

chimney top opening.

b. To seal on top of a terra cotta liner, trim the base plate 1-1/2” bigger all around the terra cotta liner outer perimeter.

Notch corners and bend the extra 1-1/2” down to make screw-on flanges.

c. To seal on top of a steel tubular vent pipe, trim to a size 2” larger in diameter than the existing vent pipe and cut slots

into the outer edge of the base plate and bend down multiple tabs to make screw-on flanges.

2. Clean the top surface and side walls of the existing chimney using a stiff wire brush or sand paper.

4.10 Log Set Installation Instructions

With door removed, carefully remove the log set foam pack from inside the firebox.

Cut the clear tapes and outer plastic wrap using a sharp utility knife or equivalent. Locate the 2 bags of coals and the
log pieces. Identify each log piece, A-F and the Large Chunk coals and Small coals per the diagrams on this page:

1. Place Log “A” on rear shelf. Two pins protruding down from Log #A slide through two holes on rear shelf.

2. Place Log B between rear burner tube and front burner tube, to the right side of pilot light assembly. Slide Log #B to

the right until log #B’s right tip touches curve in burner tube. as shown below.

85-03-01071 D30 DEEP TIMBER Page 58

3. Place log “C” behind on top of Log #A and Log #B, as shown. Wide end of Log #C sits on top of Log #A and the pin

protruding up from top of Log #B slides into a hole in the base of Log #C.

85-03-01071 D30 DEEP TIMBER Page 59

4. Log “D” has a pin in its base. This pin slides into a hole on the rear shelf, right side. The pin protruding upward from Log

#C slides into a hole in the base of Log #D.

85-03-01071 D30 DEEP TIMBER Page 60

5. Place log “E” as shown below, to the left side of the pilot light assembly. Look at the diagram at the bottom of this

page to determine the exact position of this log. This log should use the center Log Iron bar for support.

85-03-01071 D30 DEEP TIMBER Page 61

6. Log #F sits on the right side, as shown above.

❑ Place coals on front coal tray ONLY! Be sure to "fill" entire front tray with coals for true "realistic" wood log fire

appearance. Coals must not block pilot or burner flame! (Additional coals may be scattered on firebox floor for
realism). Placement of coals has a big effect on front burner flame appearance and "glow" of coals.

❑ More coals = less flame and more glow. Fewer coals = more flame, less "glow".
❑ Cycle on main burner to insure the flame runs smoothly around the curved section of the burner and lights front

burner with no delays. If there are any delays in ignition or flame movement it will be necessary to check for correct
positioning of logs and coals (coals or logs must not block pilot flame or burner flame) and to check pilot flame length.

❑ Check that the flame is "stable" and not "lifting" off burner. DO NOT proceed with operation unless entire burner

lights immediately and flame is not "lifting" off burner.

❑ Reinstall glass.
❑ You can now proceed with normal daily operation. In daily operation main burner should always be lit with Insert glass

in place.

85-03-01071 D30 DEEP TIMBER Page 62

4.11 LIGHTING CHECKLIST

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

☐ All items on "Installation Checklist" must be completed.
☐ Carefully follow all lighting and log installation instructions.
☐ Check for Gas leaks and gas pressures prior to installing facing materials.
☐ Air shutter opening 0" to ⅛" for natural gas or ¼” to fully open for 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. Do not proceed with operation if flame is "lifting off" burner after first 5 minutes.

☐ 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.

4.12 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
mad e by a qualified installer, service agency, or the gas
supplier. Very small changes in shutter settings make major
changes in flame appearance.

The rear burner air shutter adjustment knob is located on the left side of
the gas valve. Push the knob to close the air shutter or pull on the knob

to open the air shutter.

The front burner air shutter is located at the inlet end of the front
burner. This shutter is of the rotary design and is not accessible from outside. 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.

1. 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.

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

LPG Air shutter settings hint: A properly adjust ed air shutter setting will yield burner flames that have an
approximate 2” high blue color base. I f yellow colored flames are starting at burner level, air shutter is
clo sed too far and will create soot. If you ob serve that the flame is yellow starting very close to or at the
burner surface level, open air shutter. Also, if a log or part of a log is suspended and hanging inside a yello w
portion of the flame, soot can form easily on th e part of the log that is inside the yellow flame area.

IMPORTANT: Try each new shutter setting approx. ½ hr. before mak ing additional chan ges. NOTE: Changes
in fr ont burner flame can be made by re -arranging the coals and front burner air shutter opening.

blower function only. If the AC power is interrupted during a power outage, you may operate this fireplace insert.

During the power outage, the appliance’s burners will function. In addition, Flame Height adjustment function will be available.
The Fan, which is wholly dependent on 110VAC power, will not function.

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.

85-03-01071 D30 DEEP TIMBER Page 68

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 harmfu l to glass and can
lea ve a white film deposit on the glass. This d eposit can be removed , if cleaned in a timely manner, with
cleaners such as KEL KEM “Polish Plus” (part # 65 -06-0 0455) or comparable product (contact your d ealer).

Is my flame performance correct?

Your fireplace insert 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 insert is not burning correctly. Improper setup and adjustment is not
covered under warranty.

What should I do if my fireplace insert 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 insert 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. Improper log and/or ember

placement

C. Glass door seal is

compromised.

D. Incorrect gas pressure or

burner orifice size.

Corrective Action:
Open air shutter on burner fully. 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 insert won’t turn on.

What happens when I first light my fireplace insert?

When you first light your fireplace insert, 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 insert, on high fire, for two
hours with the fans on level 3. Open doors and windows to dissipate any odor. Turn your fireplace insert 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 insert

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. 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 LEVELING BOLTS

Leveling Bolts Definition

Four leveling bolts are included in the manual package. The leveling bolts allow for a ¼” minimum to 2” maximum leveling ability.
Leveling bolts are designed to adjust for uneven fireplace insert floors and yield plumb Insert Body. Use the leveling bolts only if
the fireplace insert floor is more than ¼” out of level from one side to another or from front to back. If the fireplace insert floor is
less than ¼” out of level, use metal sheet shims in various thickness and build up to needed leveling thicknesses at various points
around the appliance.
The leveling bolts supplied are designed specifically for application with this product. only use leveling bolts supplied by Mendota
and for leveling purposes only. Never use leveling bolts for purposes of lifting unit up to make up for ash lip heights or other
lifting or raising needs. Such use can cause extreme thermal expansion of firebox floor and can result in oil canning noise or
louder thermal expansion and constriction banging noise. SUCH NOISE PROBLEMS ARE NOT COVERED UNDER MENDOTA

WARRANTY

Note: When lifting this Insert more than 1”, other support blocks will be required. For all applications when
you raise the unit more than 1”, reline the entire firebox floor with refr actory brick s to build up a full level

floo r for the Insert to sit on. Do not use individual support block only under the four corners of th is unit.
WARN ING: Failure to position the parts in a ccordance with these diagrams or failure to use only parts

sp ecifically approved with this appliance may result in property damage or personal injury. Never use other
aft er-market leveling bolts. Doing so can lead to vibration noise problems or damage to internal
components.DO NOT USE LONGER BOLTS TO LIFT INSERT UPWAR D. THIS CAN CAUSE O THER SIDE EFFECTS LIKE
HEAT EXPANSION/CONTRACTION NOISES. To lift Insert up, use Firebricks and mortar or a metal b ox designed
sp ecifically for this purpose.

Figure 6-1 Pilot Flame Lengths

85-03-01071 D30 DEEP TIMBER Page 70

Leveling Bolts Installation

Perform this step after you have measured the firebox floor for level surface characteristics. Tip the Insert body on its back on
the wooden pallet. Thread one leveling bolt in to each leveling bolt receiving fastener. Thread the bolt in as far as necessary to
achieve the leveling effect desired.

6.4 HOW TO REMOVE DOORREQUIRED ANNUAL MAINTENANCE

See Chapter 5.7 What maintenance is required?
In addition to the “Required Periodic Inspections” , the following procedures m ust be performed each year by

a qualified installer, service agency or the gas supplier. Any adjustments 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 gas valve and blowers. Inspect the condition of any wiring 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 gas supplier should be contacted .
Be sure logs are re-installed per instructions.

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.

85-03-01071 D30 DEEP TIMBER Page 72

6.5 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 firing can cause permanent damage to fir ebox and det erioration of parts 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 are using a “backyard” Natural Gas well as the gas source, you must submit for mal gas analysis data

sh eets to Mendota Fireplace in serts for review and calculation of proper main burner orifice sizes prior to
fir st firing. It is known that unpurified Natural Gas from “backyard” wells can contain high energy level s
causing over firing. Further, unpurified gas can contain high levels of Sulphur and oth er compounds which
can damage the burner materials and the cera mic glass. Use of unpurified gas will void the warranty for this
product.

6.6 PILOT OUTAGE AND RE-LIGHTING

If pilot goes out, be sure to wait a minimum of five minutes before attempting to re -light. If lockout occurs
frequently, contact you Mendota Dealer for diagnosin g the problem.

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.

6.7 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.
