NOTES ON STOVE OPERATION AND EFFICIENCY
Rating:
You have purchased a Hearthstone Heritage 8024 tested to EPA Method 28R 40 CFR Part 60 where applicable. This stove
is certified to comply with the U.S. Environmental Protection Agency 2020 particulate emissions standard using crib wood. It
is certified at 0.54 gr/hr. emission rate and under specific test conditions has been shown to deliver heat at rates ranging
from 12,317 to 35,845 Btu/hr (output).
This wood heater has a manufacturer-set minimum allowable low burn rate that must not be altered. It is against federal
regulations to alter this setting or otherwise operate this wood heater in a manner inconsistent with operating instructions in
this manual.
Please refer to the Warranty section of this manual for registration instructions. In case of warranty claims, please contact
the point of original sale or the nearest authorized Hearthstone dealer. Our dealer network processes all warranty claims.
Authorized Hearthstone dealers can be located at www.hearthstonestoves.com.
This heater is designed to burn natural wood only. Higher efficiencies and lower emissions generally result when burning
air-dried seasoned hardwoods, as compared to softwoods or to green or freshly cut hardwoods. DO NOT BURN: Garbage,
lawn clippings, material containing rubber (including tires), materials containing plastic, waste petroleum products paints or
paint thinners, asphalt products, materials containing asbestos, construction or demolition debris, railroad ties, pressure
treated wood, manure or animal remains, salt water driftwood or other previously salt water saturated materials, unseasoned
wood, paper products, cardboard, plywood or particleboard. This prohibition against burning these materials does not
prohibit the use of fire starters made from paper, cardboard, sawdust, wax and similar substances for the purpose of starting
a fire in an affected wood heater. Burning these materials may result in a release toxic fumes, render the heater ineffective,
cause smoke and may damage catalysts.
Following the maintenance guidelines set forth in this manual will help insure the efficient use of your wood heater and
minimize visible emissions. Having your stove inspected by a trained professional on a regular basis will greatly increase the
potential for recognizing possible impacts to efficiency.
Proper draft is important to the efficient operation of your heater. Refer to the Normal Operation section of this manual for
information regarding adequate draft. Both excessive and sub-minimum draft can affect the efficiency of your wood heater.
Excessive draft can lead to over-consumption of fuel, lower overall heating capacity of the stove and potential over firing.
Low draft can result in inefficient burns, low heat output, expulsion of smoke into the living area when stove doors are
opened and an increased potential for build-up of flammable materials in the flue.
Efficiency:
Efficiency was measured and weighted using EPA Method 28R and CSA B415-10 methodology. A weighted average was
used to calculate the overall efficiency across all of the 4 burn rate categories using the higher heating value (HHV). The
weighted average efficiency is 77.1% (HHV).
To maximize the efficiency of your wood stove make sure it is sized properly for the space you plan to heat. An oversized
stove will often be forced to burn at a lower and dirtier burn rate. Consult with your dealer for sizing and correctly placing the
stove in your home. An incorrectly placed stove can greatly reduce efficiency. Maximizing the efficiency of your stove will
heat your house quickly, burn cleaner and use less wood.
Refer to the Choosing Firewood section of this manual for appropriate fuel selection. Seasoned firewood is typically at or
near 20% moisture content. This can be measured with any number of hand-held moisture meters available through your
local hearth shop. Follow instructions included with the meter you purchase to measure fuel wood moisture content. Burn
only dry, seasoned wood as using wet wood will greatly reduce your efficiency.
CO Emissions:
The Heritage 8024 has the following CO emission rates by burn level: Category 1 (low) –0.11 g/min, Category 2 (med. low)
–0.25 g/min, Category 3 (med. high) –0.10 g/min, and Category 4 –4.12 g/min. Wet wood or unapproved fuel described
above can greatly affect the emissions of a wood burning stove.
Smoke/Fire/CO Detectors:
It is highly recommended that smoke and CO detectors be installed throughout the heated space when a wood burning
heater is installed. Be certain to install these devices not only in the area where the wood appliance is located, but also in
bedrooms, hallways leading to other areas of the house and all common areas of the heated space. Check the batteries in
these devices and assure operation by performing whatever test operations are recommended by the manufacturer.

INTRODUCTION
Thank you for purchasing a Heritage 8024 woodstove
from Hearthstone Quality Home Heating Products.
This stove will provide years of comfortable heat. This
stove combines the warmth and comfort of soapstone
and cast iron with the efficiency of advanced catalytic
technology. The Heritage 8024 blends modern
technology with the unique beauty and qualities of
cast iron. We trust that you will appreciate the quality
of this handcrafted product.
Your Heritage 8024 woodstove burns very efficiently,
and produces a large amount of heat. However, you
should not consider your Heritage 8024 the primary
heat source for your home. The Heritage 8024’s large
glass window allows you to enjoy the fire from a
variety of locations in the room.
Please read this manual in its entirety. Its purpose is
to familiarize you with your stove's safe installation,
proper break-in, operation and maintenance. It
contains extremely important information so keep it
handy and refer to it often.
A qualified heating technician may need this owner’s
manual as a reference when installing this stove in
your home. There are national, state, and local
building codes that direct the technician on how to
install your stove. These codes stipulate the
dimension of stovepipe and clearances to walls,
ceilings, hearth, and other combustible surfaces. The
codes exist to reduce the risk of fire. Failure to follow
these instructions can result in fire, property damage,
bodily injury, and even death.
Install the stove in a safe, open area, away from traffic
flow, doors, and hallways. If possible, try to install the
stove near an existing chimney and chimney
connector. It is extremely important to install this
stove with the proper clearance from combustible
surfaces. You can purchase specific connector pipe
and special wall coverings as specified by this manual
and the NFPA 211 code to protect combustible
surfaces. As a general rule, keep furniture, drapes,
curtains, wood, paper, and other combustibles at
least 36 inches (92 cm) away from the stove. Never
install the stove in or near a storage location for
gasoline, kerosene, charcoal lighter fluid or any other
flammable liquids.
Install the stove in your central living area to allow
heat to radiate naturally to distant rooms. Do not
install your stove in a poorly insulated area. This is
inefficient and would likely result in higher fuel usage.
•SAFETY NOTICE:
AN IMPROPERLY INSTALLED STOVE CAN
RESULT IN A HOUSE FIRE. FOR YOUR SAFETY,
CAREFULLY FOLLOW THE INSTALLATION
DIRECTIONS. CONTACT LOCAL BUILDING OR
FIRE OFFICIALS ABOUT RESTRICTIONS AND
INSTALLATION INSPECTION IN YOUR AREA.
The safety of your stove will depend on many factors,
some of which include: distance to combustible
objects, correct venting, and adequate chimney
maintenance. Should you have any questions, do not
hesitate to contact your dealer for additional
information.

These fuels will cause dangerous burning
conditions in the stove. Keep all such materials
away from the stove.
•Never use a wood grate or other device to
elevate the fire.
•Never allow logs in the firebox to hit the glass
when the door is closed.
•Never slam the door or use the door to force
wood in to the stove.
•Never over-fire your stove. (See page 25)
•Never put articles of clothing or candles on a hot
stove.
•Never connect the stove to a flue used by another
appliance.
Other safety guidelines:
•Keep all combustible items such as furniture,
drapes, clothing, and other items, at least 36"
(0.92 m) from the stove (See page 10)
•Install a smoke detector, preferably in an area
away from your wood stove.
•Keep a fire extinguisher handy. We recommend
the type rated "A B C."
•Dispose of ashes properly (See page 23).
•Keep children and pets away from the stove when
it is burning; they could be seriously injured by
touching a hot stove.
•Clean your chimney system as needed. (See
page 28)
•Outside combustion air may be required if:
1. This solid-fuel-fired appliance does not
draw steadily, smoke rollout occurs, fuel
burns poorly, or back-drafts occur whether
or not there is combustion present.
2. Existing fuel-fired equipment in the house,
such as fireplaces or other heating
appliances, smell, do not operate properly,
suffer smoke roll-out when opened, or
back-draft whether or not there is
combustion present.
3. Opening a window slightly on a calm
(windless) day alleviates any of the above
symptoms.
4. The house is equipped with a well-sealed
vapor barrier and tight fitting windows
and/or has any powered devices that
exhaust house air.
5. There is excessive condensation on
windows in the winter.
6. A ventilation system is installed in the
house.
If these or other indications suggest that infiltration air
is inadequate, additional combustion air should be
provided from the outdoors. Outside combustion air
can be provided to the appliance by using the optional
outside air kit #90-53220.
PERIODIC CHECKLIST
Perform each of these tasks at the specified
intervals.
At the End of Every Week:
•Empty ashes from the firebox, sooner if the
firebox is full.
At the Beginning of Every Other Month:
•Depending upon your use of the stove, visually
inspect the chimney connector and chimney for
creosote. (see page 30)
•Check door seals using the "dollar bill test." -
When the stove is cool, shut the door on a dollar
bill. If the bill pulls out without any resistance,
then your stove’s door is not sealing properly. To
tighten the seal, adjust the door latch
mechanism or change the door gasket. (Refer to
page 30.)

Hearthstone Quality Home Heating Products, Inc ® Page 6of 39 Heritage 8024
•Inspect the face of the catalytic combustor for fly
ash and soot. Use a soft-bristled brush to
remove if present. It is recommended to visually
inspect the catalytic combustor at least 3 times
during the heating season, or every 2-3 months.
At the End of Every Season:
•Dismantle the chimney connector and clean it
thoroughly. Replace any pieces that show signs
of rust or deterioration.
•Inspect and, if necessary, clean your chimney.
•Clean out the inside of the stove thoroughly.
•Check and clean the catalytic combustor, if
necessary
•Inspect all door gasket material and replace if
worn, frayed, cracked or extremely hard.
EMERGENCY PROCEDURES
Establish a routine for the fuel, wood burner and
firing technique. Check daily for creosote build-up
until experience shows how often you need to clean
to be safe. Be aware that the hotter the fire the less
creosote is deposited, and weekly cleaning may be
necessary in mild weather even though monthly
cleaning may be enough in the coldest months.
Contact your local municipal or provincial fire
authority for information on how to handle a chimney
fire. Have a clearly understood plan to handle a
chimney fire.
If you have a stovepipe or chimney fire, follow these
instructions:
1. If the fire is too threatening, leave the area and
call the fire department immediately! If not,
perform the next three steps.
2. Close the primary air control.
3. Close the stovepipe damper (if present).
4. Close the bypass damper
5. Keep the stove front door closed!
•WARNING: DO NOT ATTEMPT TO PUT OUT A
STOVEPIPE OR CHIMNEY FIRE BY THROWING
WATER ONTO THE STOVE, STOVEPIPE, OR
CHIMNEY. THE EXTREMELY HIGH
TEMPERATURE OF SUCH FIRES CAN CAUSE
INSTANTANEOUS STEAM AND SERIOUS BODILY
HARM.
Once the chimney fire expires, leave the primary air
control and bypass handle closed and let the fire in
the stove die out completely. Inspect the stove,
stovepipe, and chimney thoroughly for any sign of
damage before firing the stove again. You must
correct any damage before using your stove again.

Owner’s Manual
Wood Handles, Screws, And
Washers (See Illustration 1 on page 8 for
installation)
The door and bypass handles are shipped inside the
stove to protect them during shipping and
installation. It is best not to install them until after
stove is moved into its final location.
The label is attached by a cable to the bottom of the
stove. Take care when lifting the stove not to
damage the label or cable. After final positioning of
the stove, the label may be stored in the holding clip
on the bottom shield of the stove.
Installing Your Stove
Choose a place to install your Heritage 8024
woodstove. Consider the location of your stove for
optimum heating efficiency. In general, it is better to
place your stove in a main living area, rather than in
a basement or other confined space.
Inspect this location to make sure that the stove and
stovepipes will have the required clearance from
combustible materials that are near the stove.
Combustibles include walls, floor, ceiling, and
chimney chase. You must carefully consider the
clearances to all of these combustibles before
actually connecting your stove.
If the floor is made of combustible material, then a
non-combustible floor protector is required between
the floor and the stove. An example of a non-
combustible floor protector is a hearth constructed
with a continuous layer of tile, brick, slate, glass or
another non-combustible facing. There is no R-value
requirement.
If you use a rear connector pipe, ensure it is listed with
Underwriter’s Laboratories. Check the listing of your
pipe with UL for the correct clearances.
The diagrams in this manual represent typical
installations, but are specific to the Simpson Dura-
Vent DVL brand.
Clearances to NFPA Code 211 Protected Surfaces
You can reduce the clearances to combustible
surfaces by using any National Fire Protection
Agency (NFPA) approved wall protection system with
additional approval of the regulatory authority having
jurisdiction in your area.. Please refer to NFPA Code
211 for specifications and complete details. You can
obtain this information directly from the NFPA

OUTSIDE AIR SUPPLY
(Optional Kit #90-53220)
You can connect an outside air source directly to this
stove using an optional outside air kit. The advantage
of providing outside air directly to the stove is that the
air used by the stove for combustion is taken from
outside the residence rather than from within the
room where the stove is located.
The outside air kit for this stove allows for the direct
connection of the stove's air intake to a minimum 3"
(76 mm) diameter duct (supplied by others)* which
leads to the outside of the house. When considering
placement of the duct from the outside of the house
to the hearth, keep in mind the need to avoid
structural members of the house. The outside air kit
attaches to the underside of the stove. Refer to the
instructions provided with the kit for installation.
For installations in Canada, where the outside air
supply kit is used, the stove must be permanently
attached to the floor for stability. See page 17 for lock
down instructions.
*An adaptor for 4” duct is available if needed. KIT #90-
53308
The International Residential Code (IRC) does not
allow the outside air duct to terminate higher than the
appliance. Some building officials restrict vertical rise
in the duct’s termination. Hearthstone recommends
the termination be at the same level, or lower than the
air intake on the stove.
Figure 6 –Outside Air Kit Detail
Locate the termination of the duct on the outside wall
of the home in such a manner to avoid the possibility
of obstruction by snow, leaves or other material.
Screen the termination using ¼” x ¼” mesh rodent
screen and cover it with a rain/wind proof hood (flex
pipe, outside termination, mesh, and hood supplied
by others) Contact your dealer for availability.
When selecting ducting and other components, note
that for installations in Canada, any air intake which
is connected directly to the outdoors must include a
damper allowing 100% closure.
TOP TO REAR VENTING CONVERSION
When installing your stove, you have the option to
vent out the rear of the stove. To convert your stove
from venting out the top to vent out the rear, follow
the steps below:

Hearthstone Quality Home Heating Products, Inc ® Page 14 of 39 Heritage 8024
1. Using a 7/16” wrench, remove the four bolts
that hold the top flue collar to the top cast.
Be careful not to drop the bolt and washers
into the stove. Remove the flue collar and
place off to the side.
2. Using a 7/16” wrench, reach through the top
opening where the flue collar was removed
from and remove the top two bolts and
washers holding the rear flue plate in and
place off to the side.
3. Loosen the bottom two bolts and washers
out of rear flue plate until the plate is free.
Remove rear flue plate and place to side.
Leave bottom two bolts in place.
4. Hold bottom two bolts in place and position
flue collar into rear exit position. Hand
tighten bottom two bolts slightly, do not fully
tighten yet.
5. Insert top two bolts with washers into top
two threaded holes of flue plate. Fully
tighten all four bolts.
6. Place the flue plate on top opening. Align
screw holes, install bolts and washers and
tighten down with 7/16” wrench.
VENTING COMPONENTS &
CONFIGURATION REQUIREMENTS
•DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE
USED BY ANOTHER APPLIANCE
•Single wall connector that is at least 24 MSG or 25
MSG blued steel stovepipe.
•Double wall connector (Rear pipe) which is used
with a listed, factory-built “Type HT" chimney or
with a masonry chimney to reduce clearances, is
available from several manufacturers, your dealer
can help you choose. Some air insulated connector
pipe models available are Simpson Dura Vent DVL
and Metalbestos DS. Security, GSW and Ameritec
also have acceptable Rear connector pipe.
•When used in a mobile home, a spark arrester is
required. (See page 18)
•The chimney connector cannot pass through a floor
or ceiling, nor any attic or roof space, closet or
similar concealed space. Where venting requires
passage through a wall or partition of combustible
construction, the installation must conform to NFPA
Code 211 or CAN/CSA - B365.

Hearthstone Quality Home Heating Products, Inc ® Page 15 of 39 Heritage 8024
•It is very important to follow minimum clearances for
chimney connectors to combustibles such as walls
and ceilings when installing the stove. Typical
chimney connector clearances are outlined below.
The single wall clearances are generic; the double
wall clearances shown are specifically for Simpson
DuraVent DVL and may vary with other brands.
Check the specifications from the manufacturer
of your connector.
COMPONENTS OF A VENTING SYSTEM
The complete venting system consists of several
components: chimney connector, wall thimble, wall
pass-through, chimney, and liner. It is absolutely
necessary that you install all of these components
and maintain the clearances to combustibles
discussed earlier to ensure a safe stove installation.
Failure to follow these instructions and specified
components or using make-shift compromises can
result in fire, property damage, bodily injury, and even
death. Be sure to follow the manufacturer’s
instructions to maintain an effective vapor barrier at
the location where the chimney of other component
penetrates the exterior of the structure.
To protect against the possibility of a house fire, you
must properly install and constantly maintain the
venting system in good condition. Be sure to inspect
the chimney connector and keep it clean. Upon
inspection, immediately replace rusted, cracked, or
broken components.
•The chimney connector is the stovepipe from the
woodstove to the chimney. The chimney connector
stovepipe is 6" (152 mm) diameter, 24 MSG or 25
MSG blued steel connector pipe. Do not use
aluminum or galvanized steel pipe - they cannot
withstand the extreme temperatures of a wood fire.
•The thimble is a manufactured (or site-constructed)
device installed in combustible walls through which
the chimney connector passes to the chimney. It
keeps the walls from igniting. You must use a wall
thimble when installing a chimney connector
through a combustible wall to the chimney.
•A wall pass-through (or chimney support package)
also keeps the walls from igniting. You must use
one when connecting through a wall or ceiling to a
prefabricated chimney.
•Only install this stove to a lined masonry chimney
or an approved high temperature prefabricated
residential type building heating appliance
chimney. Do not connect this stove to a chimney
serving another appliance; you will compromise the
safe operation of both the wood stove and the
connected appliance.
•A liner is the UL 1777 or ULC S635 (for factory built
fireplace or masonry) chimney.
You must connect your stove to a chimney
comparable to those recommended in this manual.
Do not use stovepipe as a chimney. Use stovepipe for
freestanding installations only to connect the stove to
a proper chimney.
•WARNING: DO NOT CONNECT THIS APPLIANCE
TO ANY AIR DISTRIBUTION DUCT OR SYSTEM.
INSTALLING A VENTING SYSTEM
Attach stovepipe sections to the flue collar and to
each other with the crimped end toward the stove. If
creosote builds up, this allows the creosote to run into
the stove and not on the outside of the stovepipe or
onto the stove.
Secure all joints, including attaching the stovepipe to
the stove's flue collar, with three sheet metal screws.
Install #10 x 1/2" (3 mm x 13 mm) sheet metal screws
into the holes pre-drilled in the flue collar.
Disregarding the screws can cause joints to separate
from the vibrations that result from a creosote
chimney fire.
You can simplify connecting stovepipe by using
additional accessories such as telescoping pipes,
slip-connectors or clean-out tees. These accessories
ease the periodic inspection of your chimney, as well
as allow you to dismantle the stovepipe easily
(without moving the stove).
Install the stove as close as practical to the chimney,
while maintaining all proper clearances. Install
stovepipe that is as short and as straight as possible.
Horizontal runs of stovepipe must always rise away
from the stove at a minimum of 1/4" per foot
(21mm/m).
We do not recommend long runs of stovepipe to
increase heat dispersal. Longer lengths of stovepipe,
or more connecting elbows, than necessary increase
the chances of draft resistance and the accumulation
of creosote buildup.
In general, you do not need to install a stovepipe
damper with the Heritage 8024. Some installations,
however, could benefit from a stovepipe damper,
such as a tall chimney which can create a higher than
normal draft. In such cases, a damper can help
regulate the draft. The Heritage 8024 requires a draft
between 0.06" and 0.1" WC. For drafts above 0.1"

Hearthstone Quality Home Heating Products, Inc ® Page 16 of 39 Heritage 8024
WC, install a stovepipe damper. Check the draft at
stove installation time.
Remember, the NFPA recommends minimum
clearances for chimney connectors to combustibles
such as walls and ceilings. Once the stove is installed
at safe distances from these combustible surfaces, it
is also important to maintain these connector
clearances for the remainder of the installation.
CONNECTING THE STOVE TO A CHIMNEY
You can install your Heritage 8024 to a prefabricated
metal chimney, or to a masonry chimney.
This room heater must be connected to (1) a listed
Type HT (2100° F) chimney per UL 103 or ULC S629,
or (2) a code-approved masonry chimney with a flue
liner. The chimney size should not be less than the
flue collar, or more than three times greater than the
cross-sectional area of the flue collar.
We recommend installing a cleanout tee where
possible to simplify chimney cleaning and
maintenance.
Connecting to a Prefabricated Metal Chimney
There are two ways to install a prefabricated metal
chimney:
•An interior installation where the chimney passes
inside the residence through the ceiling and roof.
•An exterior installation where the chimney passes
through the wall behind the stove then up the
outside of the residence.
Whenever possible, choose an interior chimney. An
interior chimney heats up quickly and retains its heat;
thus promotes a better draft and discourages the
formation of creosote. An exterior chimney does not
benefit from the warmth of the building, so it typically
operates at lower flue temperatures than an interior
chimney and may experience increased creosote
accumulation.
When connecting the Heritage 8024 to a
prefabricated metal chimney, you must follow,
precisely, the manufacturer's installation instructions.
Use only Type HT (2100° F), prefabricated metal
chimneys listed per UL 103 or ULC S629 standards.
Ensure the size of the prefabricated chimney’s flue is
appropriate for the Heritage 8024. The Heritage 8024
requires a 6" (152 mm) inside diameter flue for new
installations. A 6” diameter flue provides adequate
draft and performance. You can use an 8" (203 mm)
diameter existing flue with a reducer. An oversized
flue contributes to creosote accumulation. (In this
case, bigger is NOT better.)
When purchasing a prefabricated chimney to install
with your stove, Ensure you also purchase from the
same manufacturer the wall pass-through (or ceiling
support package), "T" section package, fire-stops
(when needed), insulation shield, roof flashing,
chimney cap, and any other required accessories.
Follow the manufacturer’s instructions when installing
the chimney and accessories. In addition, ensure you
maintain all manufacturers’ recommendations for the
proper clearances to the chimney.
Connection to a Masonry Chimney
Consider two primary elements when connecting your
stove to a masonry chimney: the chimney itself and
the thimble where the stovepipe connects to the
chimney. Use only code approved masonry
chimneys containing a proper flue liner.
Before connecting to a masonry chimney, hire a
professional to examine the chimney for cracks, loose
mortar, and other signs of deterioration and blockage.
If the chimney needs repair, complete them before
installing and using your stove. Do not install your
stove until the chimney is safe for use.
Ensure the chimney’s cleanout is complete and
working properly. To avoid a loss of draft, the cleanout
door must close completely and provide a tight seal.
If the cleanout door leaks, the chimney will cool, your
stove will perform poorly, and creosote can form.
Ensure the size of the chimney’s flue is appropriate
for this stove and that it is not too large. Use a
masonry chimney with a maximum 6” Diameter or 8"
x 8" (203 mm x 203 mm) tile size for best results. An
oversized flue contributes to the accumulation of
creosote.
Use the following checklist to ensure that your
masonry chimney meets these minimum
requirements:
MASONRY CHIMNEY WALL CONSTRUCTION:
•Mortared brick or modular block at least 4" (102
mm) thick –must use liner
•A mortared rubble or stone wall –must use liner
FLUE LINER OPTIONS:
•Tile - minimum wall thickness of 5/8" (16 mm),
installed with refractory mortar, and with at least
1" (25 mm) air space around the liner
•Stainless steel - UL listed 6” diameter, insulated
or wrapped liner, or the space around the liner
filled with vermiculite or suitable material (these
keep the liner warmer for better performance)

Hearthstone Quality Home Heating Products, Inc ® Page 17 of 39 Heritage 8024
•Ensure any equivalent flue liner is a listed
chimney liner system meeting type HT
requirements or other approved material.
INTERIOR CHIMNEY REQUIREMENTS:
•Must have at least 2" (51 mm) clearance to
combustible materials
•Must install fire stops at the spaces where the
chimney passes through floors and/or ceiling
•Any insulation material must be at least 2" (51
mm) from the chimney
EXTERIOR CHIMNEY REQUIREMENTS:
•At least 1" (25 mm) clearance to combustible
materials
CHIMNEY HEIGHT REQUIREMENTS (SEE FIGURE 9):
•At least 3 feet (0.9 m) higher than the highest
part of the roof opening through which it passes.
•At least 2 feet (0.6 m) higher than any part of the
roof within 10 feet (3 m) measured horizontally
from the top of the chimney.
The recommended minimum chimney height for top
of stove installation is 16 feet (4.9 m) off the floor or
13 feet 5 3/4 inches (4.1 m) from the top of the
stove. For rear exit connection, the recommended
minimum chimney height is 19 feet (5.8m) off the
floor or 16 feet 5 3/4 inches (5.0m) from the top of
the stove. The recommended maximum chimney
height is 30 feet (9m). The Heritage 8024 requires a
draft between 0.06” and 0.1” water column. Ensure
your chimney is long enough to provide the
minimum draft, and use a damper if your installation
has a required chimney height that provides too
much draft.

Part 3280 (HUD)
•An outside air kit must be used in all mobile
home installations. See page 12 for details.
•Permanently attach the stove to your mobile
home’s floor. Use the shipping clips that came
with the stove and fasteners long enough to
attach securely to the subfloor. (The clips and
fastener heads may be painted to minimize
visibility).
•
Figure 10 - Lock Down Detail
•Install a Mobile Home Chimney & Connector Kit
conforming to US/UL103 or CAN/ULC-S629,
Standard for Factory-Built Chimneys. The
system must be removable for transportation
and meet all applicable local and federal
guidelines for termination height.

Stainless spark arrester cap, storm collar,
Adjustable vented flashing –0/12 –6/12,
Two 24” chimney pipes, 24” support box
with built-in starter section and trim.
▪Failure to follow these instructions and specified
components or using make-shift compromises
can result in fire, property damage, bodily injury,
and even death.
•WARNING: DO NOT INSTALL IN A SLEEPING
ROOM IN A MOBILE HOME.
•CAUTION: MAINTAIN THE STRUCTURAL
INTEGRITY OF THE MOBILE HOME WALLS,
FLOOR, CEILING, AND ROOF WHEN INSTALLING
AND USING YOUR STOVE.
•Burning any fuel other than wood in this unit
could generate dangerous levels of carbon
monoxide within the living space.
•THE FRONT DOOR MUST REMAIN CLOSED WHEN
IN OPERATION EXCEPT FOR START UP AND
LOADING. Leaving the door open during use could
cause any smoke or fire detectors in the home to
be set off or a fire could escape the firebox and
start the room on fire.
•If this unit is installed in a mobile home, care must
be taken to ensure adequate air is available. If not
enough air is available it could starve the room of
all the oxygen. (See page 27 for more details)
•CAUTION: REMOVE THE CHIMNEY WHEN
TRANSPORTING THE MOBILE HOME!
•Be sure to follow the manufacturer’s instructions
to maintain an effective vapor barrier at the
location where the chimney of other component
penetrates the exterior of the structure.
•Chimney must be attached directly to stove.
•Chimney must extend at least 3 feet (0.9 m)
above the part of the roof through which it
passes.
•Top of chimney must be at least 2 feet (0.6 m)
above the highest required elevation of any part
of the mobile home within 10 feet (3 m) of the
chimney.
•All roof-chimney terminations must be readily
removable and reinstallable at or below an
elevation of 13-1/2 feet (4.1 m) above ground
level, without the use of special tools or
instructions.
•When the chimney exits the mobile home at a
location other than through the roof, and exits at
a point 7 feet (2.1 m) or less above the ground,
a guard or other enclosure must be installed at
the point of exit up to a height of 7 feet.
•For installations as described above, a chimney
guard or enclosure must not permit a 3/4" (19.1
mm) diameter rod to pass through it, and must
not allow a 1/2 inch (12.7 mm) rod to make
contact with the chimney when passed through
the guard a distance of 4 inches (102 mm).

OPERATION
Once your Heritage 8024 is installed, you are ready
to light a fire.
Every installation, season’s firewood, and operator’s
technique varies. Learn how to use your stove most
efficiently for your installation. We can give you the
basic principles, but only you can ensure maximizing
the potential of your stove while also operating it
safely.
•WARNING: HOT WHILE IN OPERATION! KEEP
CHILDREN, PETS, CLOTHING AND FURNITURE
AWAY. CONTACT MAY CAUSE SKIN BURNS.
Read this entire chapter before lighting your first fire.
It explains the controls and features of your wood
stove, how to choose firewood, and how to use your
stove on a daily basis.
CONTROLS AND FEATURES
Before lighting any fires, become familiar with the
location and operation of your stove's controls and
features and learn how to use them (See Figure 12).
For your own safety, do not modify these features in
any way. We recommend you use fireplace gloves
when the stove is in operation and hot.
Figure 7 - Controls & Features
FRONT DOOR HANDLE:The firebox door allows
you to load wood into your stove; a wood handle
operates the door. To open the door, pull up on the
handle and swing the door away from the stove. To
latch the door, push the door tightly towards the
firebox then continue to push the handle in and down
until it latches shut. Gently pull on the door handle to
make sure it is properly latched.
PRIMARY AIR CONTROL: The handle is located on
the front lower left of the stove, just under the ash lip.
The primary air control allows you to regulate the
amount of air entering the firebox. Generally, the
more air allowed into the firebox, the faster and hotter
the rate of burn; conversely, less air creates a slower
burn. To fully open the primary air intake, move the
handle as far as it will go to the left; move the handle
as far as it will go to the right, to close the primary air
control.
Figure 8 –Air Control
OPTIONAL ASH PAN:See the installation
instructions included with the ash pan kit if installation
is necessary. The ash pan collects burned ash from a
fire and allows you to conveniently remove the ash
from your wood stove. The ash pan and ash pan
access door is located under the ash lip. To operate
the ash grate, open the ash pan door, and simply pull
the handle out to open the ash grate and push the
handle in to close the ash grate. When the ash door
is closed, it will automatically close the ash grate.
(Refer to figure below to see the attachment of the
ash grate control handle to the control slide.) The
firebox should be cleared of ashes periodically by
sliding the ash grate towards the front door, sifting the
ashes across the grate into the ash pan, then
returning the grate to its closed position.
The ash pan is easy to remove and has a handle for
convenient disposal of ashes. Before removing the
ash pan, push it (hard!) into the stove, which kicks the
ashes further into the pan. To close the ash door,
push the door closed and turn the handle from vertical
down to its previous position. Note: The ash grate
can only be opened when the ash door is ajar or open.
Do not operate the stove unless the ASH PAN is
inserted into the stove and the ash door is closed.
This could overheat and damage the stove.
