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 com-
bustible 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 hazard-
ous.
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 circula-
tion 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.
RESIDENTIAL INSTALLATION
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 exces-
sive 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
air; this permits flexibility in planning your installation. See
Figures 24 thru 27 and their instructions for typical installa-
tion 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.
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.
WARNING
61D0008 5
OPERATIONAL GUIDELINES
CHIMNEYS
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 pos-
sibility with any fireplace or device that freely uses air on the
outside of the structure. Todayʼs homes are more energy-effi-
cient 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.
FLUE DAMPER
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.
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
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.

FIREPLACE LOCATION
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.
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.
• Locate fireplace near a load bearing wall. Make sure the support structure is strong enough or reinforced if
fireplace is to be trimmed with a heavy stone or brick facing and hearth extension.
• This fireplace may be installed along a wall, across a corner, or use an exterior chase. See Figure 2 for suggested locations.
• Location should be out of high traffic areas and away from furniture and draperies.
• Never obstruct the front opening of the fireplace.
• Do not install in the vicinity where gasoline or other flammable liquids are stored.
• Vent pipe routing. See Venting section found in this manual for allowable venting configurations.
• Minimum clearances to combustibles, side-wall, ceiling, woodwork, and windows must be maintained. See Clearances
Section in this manual.

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 open-
ing 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.

INSTALLING FIREPLACE ON COMBUSTIBLE FLOOR (CONTINUED)
This hearth extension must be either 6" (minimum) thick stone or brick; a H1652 (400 units) or H2066 (500 units) Hearth
Extension Kit; or a locally constructed hearth that has a “K” factor less than .43 and at least ½" thick. For other non-com-
bustibles, the total thickness minimum is 1.16 times its thermal conductivity (K).
The following relations could be useful —
Minor shifting of the supporting floor or
expansion and contraction may eventually
cause a crack to develop between the hearth
extension and the face of the fireplace with
either type hearth extension. To help prevent
the cracking, firmly fasten the hearth extension
materials in place. Screw wall ties to the face of
the fireplace. Imbed the wall ties in the mortar
joints of brick, stone, or other non-combustible
materials.
Place metal safety strip packed with the
fireplace beneath the fireplace. Extend metal
safety strip under the hearth extension or into
a mortar joint of the hearth. See Figures 6
through 9. If a crack does eventually develops,
the metal safety strip will prevent sparks or
embers from falling from the fireplace onto
combustible flooring materials.

INSTALLING CHIMNEY SAFETY INFORMATION
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.
CHIMNEY INSTALLATION
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.
WARNING
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.

CHIMNEY INSTALLATION
LOCATING CENTER LINE
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.
Note: Make sure the chimney location is well away from
ceiling and roof joists and/or anything else that might
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 FIRESTOP SPACER
Install the firestop spacer from beneath the ceiling as shown in Figure 17 unless the space above is attic space.
In an attic, install firestop spacer at the floor level of attic. You must have joists or headers on all four sides of the spacer.
Use a minimum of four (4) 8-penny nails to secure the spacer. See Figure 18.

Note: Dimensions may vary slightly due to manufacturing tolerances.
Figure 19 - Chimney Sections for Elbow Offsets
INSTALLING “S” SERIES CHIMNEY SPACERS
To install the “S” series chimney sections, insert the male end of the flue (the smallest diameter pipe) into the flue outlet of
the fireplace. Press down until the snap locks engage. Continue to add chimney sections on top of each other until chimney
is at least 6" above roof opening on all sides. See Figure 19.
Note: As the chimney sections are installed, check each joint to make sure it is properly locked to the
previous section.
Make outer pipe stronger by using two or three sheet metal screws placed through the area where the outer pipes overlap one
another. Carefully drill a 1/8" diameter hole through the chimney sections. Do not drill into inner stainless steel flue pipe.
Be very careful when drilling the holes
into the outer pipe. Do not drill into
inner stainless steel flue pipe.

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.
6. Continue installing the vertical portion of the chimney. See Figures 22
and 23.

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.

CHIIMNEY INSTALLATION
CHIMNEY CAP CHASE INSTALLATION
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.
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.
Be careful around electrical wires
to avoid the electrical shock hazard
of contacting the wires with the
metal chimney components.

FIREPLACE OPERATION
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 fertil-
izer 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.
Fireplace damper must
be fully opened when
using a gas appliance.
WARNING
See Gas
Appliance
Installation for
more guidelines.
HOW TO BUILD A BETTER FIRE
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.
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.
WARNING
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 hand-
ful 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
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.
SPECIES VALUE DENSITY HEAT
Dogwood .70-.79 100-107
Hickory .70-.74 100
Oak .60-.73 86-99
Black Locust .69-.70 95-98
Beech .64-.66 89-91
Hard Maple .58-.65 83-88
Birch .55-.64 79-86

White Pine .35-.37 50
A FEW WORDS OF CAUTION
Do not burn plastics, poison ivy twigs and stems and chemi-
cally 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 environ-
mental 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.
36 61D0008
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 fit-
ting 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
Creosote, Formation and Need for Removal
hen wood is burned slowly, it produces tar and other organic
vapors which combine with expelled moisture to form creo-
sote. The creosote vapors condense in the relatively cool chim-
ney flue of a slow-burning fire. As a result, creosote residue
accumulates on the flue lining. When ignited, this creosote
makes an extremely hot fire.
Note: The chimney should be inspected at least twice
a year during the heating season to determine
if a creosote buildup has occurred. If creosote
has accumulated it should be removed to
reduce the risk of a chimney fire.
The chimney cap can be removed for inspection, maintenance
and cleaning by removing three screws from the support legs
and lifting upward.
When the fireplace is new, inspect the chimney often and clean
the chimney any time creosote is seen on the flue walls. Once
you see a pattern of how often creosote is accumulating, you
can determine how often the chimney should be inspected.
Also changes in the outside environmental conditions such as
temperature and humidity or changes in the operation of the
fireplace can lead to rapid buildup of soot and/or creosote.
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.
FIREPLACE MAINTENANCE
At the end of each heating season or when the fireplace will not
be in use for an extended time, the ashes should be removed
and the hearth area should be swept clean. The slow absorption
of moisture into the ashes over a long period of time could
corrode metal fireplace parts.
At the beginning of each heating season, always operate the
flue damper and make sure it has not become stuck from soot,
creosote, etc.
Keep the lower and upper grille panels clean and free from
dirt and lint accumulation at all times to get the maximum
efficiency from your fireplace.
As you use the fireplace, expansion and contraction will cause
minor cracking of the hearth, back and side refractory mate-
rials. This is normal and unavoidable. If the cracks become
large enough or parts dislodge and metal behind the refrac-
tory is exposed, the refractory panels should be replaced with
new panels. Obtain these panels Martin Hearth and Heating
fireplace dealer.
