OPERATION GUIDELINES
HOW YOUR FIREPLACE SHOULD BE USED
This ﬁreplace is intended for supplemental heating only and
is not intended for use as a primary heating system.
This ﬁreplace is designed to sit directly on a combustible
ﬂoor. The ﬁreplace must be installed with clearances to combustible building materials as speciﬁed by this manual. Only
parts manufactured by Martin Hearth and Heating and labeled
for use with this ﬁreplace should be used in the installation
of the ﬁreplace except for special roof ﬂashings that may be
fabricated locally. The use of improper parts in the installation
can be hazardous and voids the warranty offered by Martin
Hearth and Heating.
This ﬁreplace is designed to burn solid wood fuel (wood),
UL- classiﬁed processed solid fuel ﬁre logs, or a certiﬁed
decorative gas appliance may be installed in the ﬁreplace as
described later by this instruction manual.
This ﬁreplace is not designed to burn coal, unplumbed liquid
fuels, unplumbed gaseous fuels or household refuse. Any
attempt to burn these fuels in the ﬁreplace can be hazardous.

HOW YOUR FIREPLACE WORKS
As wood is burned in the ﬁreplace, room air entering the
ﬁreplace is circulated around the ﬁreplace ﬁrebox. This air
circulation protects the ﬁrebox from overheating. Air circulation through the ﬁreplace must not be blocked or restricted
in any manner. Blocking or restricting air circulation through
the ﬁreplace can cause a ﬁre hazard.

air; this permits ﬂexibility in planning your installation. See
Figures 24 thru 27 and their instructions for typical installation of outside combustion air kits. Review the precautions
and recommendations in this manual pertaining to outside
combustion air.
Note: Outside air for combustion is optional in
residential type installations unless required
by local codes. Outside air for combustion
it is mandatory in manufactured home
installations. Use an AK6 outside combustion
air kit in manufactured home installations,
instead of the AK4 offered for residential type
installations.
GLASS DOORS
Glass doors (models GD36BA, GD36PBA, GD36SSA,
GD42BA, GD42PBA and GD42SSA by Martin Hearth and
Heating) may be installed to receive the maximum beneﬁt
from your ﬁreplace. For large ﬁres, the maximum heating
beneﬁt from the ﬁreplace will be obtained with the doors open
due to the high amount of radiant heat being emitted out of
the front opening of the ﬁreplace. With a small ﬁre, or before
retiring in the evenings, it is best to operate the ﬁreplace with
the doors closed to prevent excessive room air from being
drawn up the chimney. When the doors are open, the mesh
screens should be closed to help keep burning embers from
popping out of the ﬁrebox.
Note: Glass doors are mandatory on ﬁreplaces
installed in manufactured homes.

In residential type installation, an AK4 outside combustion air
kit may be connected to the left side of the ﬁreplace to allow
outside air to enter the ﬁrebox through a dampered opening in
that side of the ﬁreplace. This outside combustion air feature
reduces the room air used for combustion and prevents excessive heat loss from the room. When the ﬁreplace is in use,
the ﬁreplaceʼs “outside combustion air” damper connected
to an AK4 may be opened to allow air from outside to enter
the ﬁreplace ﬁrebox. When the ﬁreplace is not in use, the
“outside combustion air” damper should be closed to prevent
cold air from entering the ﬁrebox. An “outside combustion
air” damper is open when its control lever is up and closed
when its control lever is down. A control lever for the outside
combustion airdamper is located inside the ﬁrebox near the top
of the side ﬁrebrick on the left side of the ﬁreplace. The design
of the ﬁreplace allows the routing of the combustion air duct
downward or horizontally to obtain the outside combustion

WARNING

RESIDENTIAL INSTALLATION

Fireplaces equipped with glass doors
should be operated only with the
glass doors fully open or fully closed.
If doors are left partly open, gas and
ﬂame may be drawn out of the ﬁreplace
opening, creating risks of both ﬁre and
smoke.

61D0008

OPERATIONAL GUIDELINES
FLUE DAMPER

CHIMNEYS

The ﬁreplace also is equipped with a ﬂue damper which must
be open when the ﬁreplace is in use. The ﬂue damper control
lever is located inside the ﬁreplace. The counterweighted
damper is operated by simply unlocking up to open or pulling
and locking down to close the damper. When the ﬁreplace is
not in use, the damper should be closed to prevent cold air
form entering the chimney as well as preventing warm air in
the room from escaping up the chimney.

All ﬁreplace chimneys are in direct contact with cold air on the
exterior of the structure. Consequently, when the ﬁreplace is
not in use, cold air can fall down the chimney of the ﬁreplace
to cool off the ﬁreplace chase. Therefore, the ﬁreplace chase
must be insulated to minimize the risk of cold coming into
the home. Even if the ﬁreplace chase is adequately insulated,
this cannot completely ensure that cold air coming into the
structure will be eliminated. Cold air coming inside is a possibility with any ﬁreplace or device that freely uses air on the
outside of the structure. Todayʼs homes are more energy-efﬁcient and, therefore, better insulated and tightly constructed.
Unfortunately, when air is removed from the house (by a
bathroom fan or consumed by a furnace) additional air is
needed to replace the air consumed. Unless the additional air
is supplied, this can cause a negative pressure in the home.
When this happens, the house will draw in outside air from
the cracks in the windows, down the ﬁreplace ﬂue or other
locations of air leakage in the home. Because cold air coming
in may be unavoidable in some structures, Martin Hearth
and Heating is not responsible for heat loss or air inﬁltration
through or around the ﬁreplace.

Note: It is normal for a small amount of smoke to
be released from the upper portion of the
ﬁreplace the ﬁrst few times you use your
new Martin Hearth and Heating fireplace.
This results from an oil residue on the metal.
Open a door or window to allow the smoke
to escape.
GRATE

WARNING

The grate included with this ﬁreplace helps to appropriately
locate and contain the burning wood.

Failure to use this grate may cause
overheating of parts of the ﬁreplace
and allow large pieces of burning
wood to roll forward out of the ﬁrebox.
Replace warped or damaged grate
only with a Martin Hearth and Heating
grate.

Plan for the installation of your ﬁreplace. This includes determining
where the unit is to be installed, the vent conﬁguration to be used, framing
and ﬁnishing details, and whether any optional accessories (i.e. blower,
wall switch, or remote control) are desired. Consult your local building
code agency to ensure compliance with local codes, including permits
and inspections.

CAUTION

FIREPLACE LOCATION

Do not install ﬁreplace
over carpeting.

The following factors should be taken into consideration:
• This ﬁreplace should have sufﬁcient access for its safe operation and maintenance.
• Locate a position where the ﬂue system of the ﬁreplace can be properly installed without damaging the integrity
of the building. e.g. cutting wall or ceiling joist (example: load-bearing framing members).
• Install ﬂoor protection when the appliance is installed directly on tile or other combustible material.
• Check ﬁreplace and ﬂue system clearance requirements.
• Locate the ﬁreplace in a large and open room that is centrally located in the house. This will optimize heat
circulation and comfort.
• Locate ﬁreplace away from frequently opened doors, central heat outlets or returns, or other places where air
movements may disturb the airﬂow around the ﬁreplace.
Note: Air turbulence near the ﬁreplace may cause smoke to spill out of the ﬁreplace opening.

INSTALLATION PREPARATION
LOCATING CHIMNEY
•

Survey the planned location for the ﬁreplace for overhead plumbing or electrical wires, etc. This could make installation
harder. It could also be a hazard for persons installing or cleaning the chimney.

•

Do not install where the chimney cap will be near abrupt changes in the roof shape, nearby wall or embankments, under
or near trees or above the roof of a single story wing of a two story building. See Figure 4. Any of these conditions may
cause turbulence or pressure condition which may create poor chimney draft and smoke spillage from the ﬁreplace opening into the home.

•

Use elbows to offset the chimney to avoid obstructions or to locate the chimney cap in a better location. See Chimney
Offsets Section on pages 18 and 21 for instructions on proper elbow use. Poor installation or location of the chimney cap
and/or components can cause wind blown rain to enter the chimney.

•

The selected location must have a 15" square combustible material-free space for the chimney to pass through.

•

If the chimney is to pass through living or storage spaces, there must be adequate space to enclose the chimney to avoid
personal contact with, or damage to, the chimney.

CHIMNEY INSTALLATION
INSTALLING CHIMNEY SAFETY INFORMATION

WARNING

You must properly install the chimney to assure safe and satisfactory performance of the ﬁreplace. This is an important part
of the installation. Review the Chimney Installation Section thoroughly.

For your safety, some of the important things to remember in regard to chimneys are
listed below:
• Use only parts and accessories labeled for use with this ﬁreplace.
• Use only undamaged parts and accessories.
• Enclose the chimney where it passes through the living spaces to prevent contact with
and possible damage to the chimney.
• Install ﬁrestop spacers at each ceiling level.
• Install the proper chimney cap or chimney housing on the chimney to prevent the entry
of rain and debris into the chimney and to assure the proper venting of smoke.
• Do not use more than four elbows in the chimney.

Note: To select the proper chimney height, see Figures 12 through 16. The ﬂue outlet must be a minimum
of 3' above the highest point where the chimney penetrates the roof and a minimum of 2' above all portions
of the building within ten feet. If the chimney is to include elbows to offset the chimney, see Chimney Offset
and Cap Installation Section. There must be at least 2" air space between all sections of the chimney and
combustible materials between ﬂoors.
Do not extend the chimney more than 90" above the roof without additional support.

LOCATING CENTER LINE

Center Line
to Chimney

You will need to lay out, cut and frame openings through all ceilings
and the roof at the point where the chimney will pass through.
Place ﬁreplace in planned position for installation. Unless the chimney
is to be offset, the point where the center line of the chimney will pass
through the ceiling and roof can be determined with a plumb line. See
Figure 16. Drive a nail in the center point.

be in the way.
Drive a long nail through the roof from underneath to mark the roof
opening center line. Make sure the nail is long en ought to go through
the roof and be seen on the rooftop. If the chimney is to penetrate a
pitched roof, the hole in the roof must be rectangular instead of square
and should be sized according to Table 1.

INSTALLING CHIMNEY SUPPORTS
Note:

Outer Pipe

For a total ﬁreplace installation of more
that 30' feet, you must use chimney
support model SCS at or below 30'
to support the weight of additional
chimney pipe.

To install the chimney support, place the crimped end of
the ﬂue and outlet air duct portions into the last section
of chimney pipe. Push down until the outside of inlet
air duct of the chimney support overlaps and snap locks
the chimney support into the chimney section.

ELBOW INSTALLATION
The following are important points that should be observed when installing elbows on the ﬁreplace.
1. Securely nail down to the surrounding structure support straps of all elbows not installed directly on top of the ﬁreplace.
This allows the support strap to carry the weight of the chimney above the elbow and prevents this weight from breaking
the elbow or chimney sections apart.
2. Do not use elbows in any combination that inclines the chimney more than 30° from vertical. See Figure 21.

STRAIGHT RUN
CHIMNEYS
Chimney support is required at
25' chimney height.

CHIMNEYS WITH
ELBOW OFFSETS
The length of the inclined portion of the chimney between
elbows must not exceed 6' when
unsupported.
The length of the inclined portion of the chimney between
elbows must not exceed 20' if
the chimney is supported at 6'
intervals using either metal support straps or an SCS chimney
support.
The SCS chimney support when
installed at a 30° angle will add
8' of rise and 45/8" of offset to the
chimney height calculations.

CHIIMNEY INSTALLATION
OFFSET INSTALLATION SEQUENCE (CONTINUED)
1. Install the ﬁrst SE30 elbow by placing the extended ﬂue into the mating
part of the ﬁreplace or chimney section. Push down until the outside of
inlet air duct of the elbow overlaps. Snap lock the elbow into the ﬁreplace
or chimney section.
2. Nail the support straps to the framing member with a minimum of two (2)
8-penny nails per strap.
3. Install the sections of pipe between elbows until the proper number of
chimney sections have been installed.
4. Install the second elbow to return the run of the chimney to vertical.
5. Nail the support straps of the second elbow to a building frame member.

Note: If the inclined portion of the chimney passes through a ﬂoor or ceiling, an SF30 ﬁrestop spacer should
be installed to provide the ﬁrestop and support required. Be sure proper spacing in maintained
between the chimney and combustibles. See Figure 23.

CHIMNEY CAP INSTALLATION
MODEL SC CHIMNEY CAP
Note: The proper chimney height is important to assure proper draft and safety.The chimney cap must
extend the ﬂue outlet 4" above the top of the last section of chimney. Keep this mind when
determining the proper height for the chimney. The chimney should not be extended more than
90" above the supporting roof structure without additional support. In the case of an “A” frame
type construction or other steep pitch roofs that require more than 90" of chimney above the roof,
attach a support to the chimney at the 90" level that is strong enough to support a wind load of
31/8 pounds for each inch the chimney extends above 90". The ﬂue outlet must be a minimum of 3'
above the point where in penetrates the roof. See Figure 24.

air duct or largest diameter pipe in place until Step 3 is completed.
2. Remove the shingles from around the chimney so that the ﬂashing
may be installed. Install the upper part of the ﬂashing under the
shingles.
3. Set the ﬂashing on the roof. Scribe a line around the ﬂashing. Cut
1/4" below the scribed line. This should increase the diameter of the
ﬂashing outlet enough to allow the ﬂashing to be placed over the
chimney. See Figure 25.
4. Snap the last section of inlet air duct in place. Slide ﬂashing over the
chimney. Check for minimum clearances. Adjust chimney if necessary to make minimum clearances.

where speciﬁed on the brackets. Fasten chimney pipe down with the No. 8 screws provided. Note: Do not penetrate
the inner stainless steel pipe while installing the screws.
10. Check all the parts of the ﬁreplace, chimney and chimney termination cap. Make sure none have been damaged or bent
during installation. Check to see that all parts have been properly installed.
Note: The metal used for chimney cap has a rust-protective coating but the cut edges of the parts are not
protected. Detergent-wash and paint exposed parts of chimney cap with galvanized primer paint.
This will prevent rusting and rust staining of nearby structures.

CHIIMNEY INSTALLATION
CHIMNEY CAP CHASE INSTALLATION

WARNING

The preinstalled chimney sections must be no more than 10" below the top of the chase. Plan the installation so that either
a 2' or 3' chimney section will be used for the top section. This is necessary to completely install inlet air telescope and
chimney cap into the top section.

Be careful around electrical wires
to avoid the electrical shock hazard
of contacting the wires with the
metal chimney components.

Note: When two ﬁreplace chimneys are terminated
above the same chase, the centers of the chimney caps
should be at least 24" apart to help prevent smoke from
ﬁreplace in use from being drawn down the chimney of
ﬁreplace that is not in use. Additional spacing between
caps or staggering the height of the caps will also
help.

1. Extend the chimney sections until the top of the chimney is not more than 10" below top of the chase.
2. Center the hole in the chase cover over the chimney. Lance and form chase cover overhang over the chase. Secure chase
cover overhang with nails. The chase cover overhang keeps water from seeping under the chase cover. If two or more
chase cover overhangs are to be used on the same chase, solder the chase covers together to form watertight seams.
3. Place the inlet air telescope inside the hole in the chase cover. Lower inlet air telescope down into the mating pipe of
the chimney until ﬂange on the telescope section rest on ﬂange of the chase cover overhang.
Note: All telescoping sections should extend a minimum of 3" inside the mating chimney pipes.
4. Place SCL or SQL8 chimney cap into matching duct telescope and ﬂue telescope of the last chimney section. See Figure
27. Lower the cap until the brackets on the bottom of the chimney cap rests on the raised ﬂange of the ﬂat ﬂashing.
Punch or drill 1/8" diameter holes in the raised ﬂange of the ﬂat ﬂashing. Fasten cap to the ﬂashing with the No. 8 screws
provided.
5. Check all parts of the chimney and chimney cap. Make sure none have been damaged or bent during installation. Check
to see that all parts have been installed properly.
Note: The metal used for the chimney and chimney cap has a rust-protective coating but the cut edges of
the parts are not protected. Detergent-wash and paint exposed parts of the chimney and chimney cap
with galvanized primer paint. This will prevent rusting and rust staining of nearby structures.

OUTSIDE COMBUSTION AIR PRECAUTIONS AND RECOMMENDATIONS
COMBUSTION AIR
1. Locate combustion air assembly at an exterior location which is not likely to be accidentally blocked in any manner.
Locate assembly above the snow line to prevent blockage by snow accumulation.
2. Never mount the combustion air inlet assemblyin a garage or storage area where combustible fumes such as gasoline
might be drawn into the ﬁreplace.
3. Combustion air can be drawn from the crawl space under a house when an adequate supply of air is provided by open
ventilation.
4. Do not take combustion air from attic space or garage space.
5. Avoid extremely long runs and numerous turns in the duct leading from the ﬁreplace to the combustion air assembly.
These conditions increase the resistance to the free ﬂow of air through the duct. See Figures 28 through 31 for methods
of installing the outside air for combustion assemblies.

1. Remove the cover plate from the 4" outlet opening location on the left or
right outside of the ﬁreplace.
2. Place the insulation ring between the AK-4 starting collar and fireplace wall.

WARNING

The use of outside air for combustion is optional unless required by building codes. It is only necessary to supply outside
combustion air to one side of the ﬁreplace. Use the model AK4 combustion air kit.

DO NOT remove the
cover if the outside air
will not be connected.

3. Place the starting collar (4") into the hole on the side of ﬁreplace. Fasten it in place with the four sheet metal screws
provided. See Figures 32 and 33.
Note: The air starting collar extends through the ﬁreplace outer wrap. When the air starting collar is

HOW TO BUILD A BETTER FIRE
Fireplace damper must
be fully opened when
using a gas appliance.

See Gas
Appliance
Installation for
more guidelines.

ADVANTAGES OF A WOOD BURNING
FIREPLACE
These are practical and ecological advantages of using wood
as a fuel. Also to be considered is the aesthetic appeal. Most
of us consider a wood ﬁre with nostalgia. We enjoy the aroma
and ﬁnd the ﬂickering light of a cozy hearth reminding us of
things past. Wood has a low ash content. The little ash that
remains after burning is useful in home gardening as a fertilizer and soil conditioner.

WHICH WOODS ARE BEST?
Each wood species offers something different in aroma or
heat value. You should consider your needs and desires before
building your ﬁre.
Softwoods, like pine, spruce and ﬁr are easy to ignite because
they contain a lot of resin. However, a ﬁre built entirely of
softwoods burns out quickly. You also must add wood more
often. While a softwood ﬁre is not too desirable for a long
evening, itʼs ﬁne in the morning when you want quick warmth
or late in the evening when you want a ﬁre that will burn out
before you go to bed.
On occasion when a longer ﬁre is desired, itʼs best to combine
softwoods with the heavier hardwoods such as ash, beech,
birch, maple, oak and hickory. Hardwood burns slower, with
shorter ﬂames, and produce steady, glowing coals.
For the most pleasing aroma, burn the wood of fruit trees
such as apple and cherry, or nut trees such as beech, hickory
and pecan. This wood is generally more expensive, but a
little combined with other wood goes a long way. Start your
ﬁre with a mixture of softwood and hardwood. Add some
fruit or nut wood for nostalgic aroma. Since most woods
will not burn well when freshly cut, the wood you purchase
should be reasonably dry. Purchase logs that will ﬁt when laid
across your grate. Ask that the larger, heavier logs be split.
Kindling should be short, easily split lengths of softwood,
lumber yard or mill scraps, or twigs and branches gathered
from your yard.

The ﬁrst three ﬁres should be of moderate size. This lets the
ﬁreplace adjust to the heat and the bricks to cure.
First, make sure your room is well ventilated, your damper
open and the ﬂue is unobstructed. Then make sure your wood
is dry and seasoned. Unseasoned wood burns poorly. If you
use unseasoned wood with poor ventilation or an obstructed
chimney, smoking could occur.
If your ﬁreplace is equipped with an outside combustion air
assembly, open the combustion air inlet by pushing upward
on the lever located above the ﬁrebrick on the left side of the
ﬁrebox.

WARNING

FIREPLACE OPERATION

Never use gasoline, gasoline-type
lantern fuel, kerosene, charcoal lighter
fluid, or similar liquids to start or
“freshen up” a ﬁre in this ﬁreplace.
Keep all such liquids well away from
the ﬁreplace while it is in use. Use
of this fuel can cause a serious
explosion.

Prepare your ﬁre by placing two logs on the iron grate or ﬁre
basket, and laying the tinder between them. Tinder may be
dry scrap paper, twigs or bark. On top place a small handful of twigs or split softwood kindling. Place more dry logs
over this base. Keep logs close together, as narrow air spaces
between them promote better drafts. Heat reﬂected between
adjacent surfaces aids in raising and maintaining combustion
temperatures.
Youʼll need a minimum of three logs, preferably four, to
make a good ﬁre. Add kindling and new logs as needed to
rekindle a dying ﬁre. New logs should be added at the rear
grate after raking the coals toward the front. Note: Do Not
Overﬁre the Fireplace. Overﬁre conditions happen when
you use large amounts of kindling, building scraps or other
improper fuels.
Ashes are important because they form a bed of glowing
coals. Let ashes build up to 1" to 2" on the bottom of the
grate. Excess ashes can be used to check a ﬂaming ﬁre or to
“bank” your ﬁre. Cover the logs with ashes. A “banked” ﬁre
will hold glowing coals for 8-10 hours, thereby saving a ﬁre
for later use.

FIREPLACE OPERATION
WOOD VS. FOSSIL FUELS

A FEW WORDS OF CAUTION

Compared to fossil fuels, a full cord of dry hickory weighs
about two tons and is approximately equal in heating value
to a ton of hard coal. On a per pound basis, heavy hardwoods
have about half the heating value of coal. The table below
shows the relative densities and heat values of a variety of
dry woods. Varieties at the top of the list (Dogwood) burn
longer and those near the bottom (White Pine) ignite and
burn quicker. A combination of both light and heavy wood
is desired.

Do not burn plastics, poison ivy twigs and stems and chemically treated woods such as discarded poles and railroad ties
in your ﬁreplace. These create air pollution and can cause
extreme irritation for some people.

Use hemlock, spruce, juniper and other resinous woods with
caution. They contain moisture pockets which, upon heating,
“pop” with considerable vigor.
Always use a ﬁre screen. Always “bank” a ﬁre (or at least push
all unburned fuel to the rear of the grate) before leaving a ﬁre
unattended. Do not use this ﬁreplace as an incinerator.
The termination of the chimney above the roof is exposed to
wind, cold, and pressure changes. These and other environmental conditions may make it hard to get a sufﬁcient chimney
draft at times. At other times the draft may be sufﬁciently
disrupted and cause smoke to spill from the ﬁreplace opening.
If problems with chimney draft occur, help start chimney draft
before you build a ﬁre by holding a piece of burning paper
near the ﬂue opening at the top of the ﬁrebox to preheat the
chimney. If smoke spills from the ﬁreplace opening after the
ﬁre is burning, open a window on the up wind side of the house
that is far enough away form the ﬁreplace that the wind will
not blow across the ﬁreplace opening. Push burning wood as
near the back of the ﬁreplace as possible. If your ﬁreplace has
glass doors, close them.
IMPORTANT: Do not leave children or physically or
mentally handicapped, or senile persons alone with a
burning ﬁreplace.

MAINTENANCE
FUEL STORAGE
Wood can be dried sufﬁciently for burning within a few weeks
if protected form rain in a low humidity area. It is better to
cut wood and allow it to dry for a year. In all cases, the wood
should be stacked so that both ends of the sticks are exposed
to the air and protected from rain. The drier the wood, the
more usable heat produced by the ﬁre and less likely rapid
accumulation of soot and creosote within the chimney is to
occur. See Chimney Maintenance for information on the
hazards of soot and creosote accumulation. Small quantities
of wood required for ﬁre tending must be kept at least 30"
from the ﬁreplace.

DISPOSAL OF ASHES
Ashes should be placed in a metal container with a tight ﬁtting lid. The closed container of ashes should be placed on
a noncombustible ﬂoor or on the ground well away from all
combustible materials until they are ﬁnally disposed of. If the
ashes are buried or locally dispersed, they should be kept in
the closed container until all cinder has thoroughly cooled.
Ashes should never be placed in a container with combustible
materials.

CHIMNEY MAINTENANCE

Have a a qualiﬁed and reputable chimney sweep clean the
chimney or remove creosote or soot with brushes on wooden
or fiberglass poles. Note: Do not use metal pipes,
chains, wires, etc., to clean the chimney. They can
scratch the surface of the stainless steel ﬂue. This
will shorten the life of the ﬂue and provide a rough
surface for soot particles to attach to.
Be sure to cover nearby furnishing and arrange some method
of catching soot and creosote particles that may fall during
the chimney cleaning process. If glass doors are installed on
the ﬁreplace, they should be closed. Extra caution must be
used to avoid damage to the ﬂue damper during the cleaning
process.
In addition to checking and cleaning the chimney on a regular
basis, be sure to inspect the chimney before starting a ﬁre at
the beginning of each heating season. Make sure the chimney
is clear from any accumulation of soot, creosote or any other
debris. Make sure all joints are intact.
Martin Hearth and Heating does not recommend chemical
cleaners because some may contain elements that corrode the
metal parts of the chimney or ﬁreplace.
