General Information
The EPA Phase 2 qualied Standard Series replace
system is a prefabricated, refractory modular replace and
chimney system designed for eld assembly. The system
consists of interlocking precast parts which are glued together
with a masonry adhesive.
The parts of the EPA Phase 2 qualied Standard Series
replace system and DM 54 chimney system are precast using
a proprietary mixture of volcanic pumice aggregate and cement.
It includes all the parts necessary for assembly of a complete
rebox, smoke dome and chimney system.
Each EPA Phase 2 qualied Standard Series replace
component is designed for a specic part of the replace such
that only one means for assembly is possible.
The EPA qualied model requires an in-line or
chimney top damper.
The EPA Phase 2 qualied Standard Series replace
system requires a EPA Phase 2 qualied Standard Series replace
refractory re brick liner be applied to the interior of the rebox.
Fire brick must be a minimum thickness of one and one-eighth
inch (1-1/8”).
The EPA Phase 2 qualied Standard Series replace
system is available in one size: thirty-six inch (36”). This unit
has a thirty inch (32”) rough opening height before re brick.
The DM 54 chimney system is a dual module refractory
chimney system. The basic chimney consists of an outer casing
block and an inner liner with a fourteen inch (14”) diameter
ue hole. The chimney components are eld assembled using
Earthcore Mortar to glue the components together.
The DM 54 chimney system also includes an offset
chimney block component, used to create offsets to the vertical
run of the chimney. A brickledge component is available,
designed to support chimney top brick veneer nishes.
Prefabricated masonry chimney termination caps are also
available.
The various EPA Phase 2 qualied Standard Series
replace system components will be described and illustrated
in the following pages. Close attention should be paid to each
component group’s specications and installation requirements
as described in this manual.
Important: Due to heat and weight issues, the EPA Phase 2
qualied Standard Series replace installations require that the
system be built upon a non-combustible concrete slab with no
wood underpinnings supported to footings with concrete or steel
and designed to carry the total weight of the Isokern replace
and chimney system.
The Fire-Lite application of the EPA Phase 2 qualied
Standard Series replace replace is designed to be built upon a
combustible oor system and will also require a design that will
support the total weight of the Isokern replace and chimney
system. The FTF-13 or equivalent chimney system only must be
used with the Fire-Lite application.
Chimney system installations over 57’ - 0” will require
additional support.

Intended Use Statement
Intended Product Use Statement:
The EPA Phase 2 qualied Standard Series replace
and DM 54 chimney systems are intended to burn solid wood
fuel, propane or natural gas.
Note:
Installation of a gas pipe must comply with the
Standard for Decorative Gas Appliances for Installation in
Vented Fireplaces, ANSI Z21.60.
This replace is not designed to sit directly on a
combustible oor system. The Fire-Lite application is designed
to sit on a combustible oor. This replace is intended
for use as a supplemental heat source only and is not intended
for heavy use as a primary heating system.
Overring, abusive burning or mistreatment will void
any claims (eg. burning construction debris or other highly
ammable material; tossing, kicking or otherwise forcing logs
into the rebox).
EPA Phase 2 qualied Standard Series replace and
DM 54 chimney systems are conventional indoor or outdoor
replaces designed to appear like traditional masonry replaces.
EPA Phase 2 qualied Standard Series replace and DM 54
chimney system units are intended for installation in residential
homes and other buildings of conventional construction.
Note: The local authority having code jurisdiction should be
consulted before installation to determine the need to obtain a
permit.
Important areas of concern with the installation of
these replaces are: construction of proper load bearing
foundation and concrete support slab; code required hearth
extension substrates and supports; proper assembly of
components; clearance to combustible materials; height of
chimney; and, techniques employed in applying nishing
materials to the replace opening and hearth extension.
Each of these important topics will be covered in detail
throughout this manual. Installation personnel must give special
attention to each topic as the installation progresses.
All work performed on, near and adjoining the replace
and chimney installation must meet or exceed the specications
and requirements in this manual and the prevailing local building
code.
Subsequent renovations, additions of cabinets and
storage spaces in the enclosure surrounding the replace are also
limited to the specications in this manual and to the prevailing
local building code.
Isokern is not responsible for other construction work
around the replace unit.
Note: Do not scale drawings. Illustrations in this manual are
not to scale and are intended to show “typical” installations.
Nominal dimensions are given for design and
framing reference only, since actual installations may vary
due to job specic design preferences. Always maintain the
stated minimum clearances to combustible materials. Do not
violate any specic installation requirements.
The EPA Phase 2 qualied Standard Series replace
and DM 54 chimney system is tested and listed by Warnock
Hersey (Intertek Testing Service) - Report No. 315965MID008 and Report No.315986MID-006 - to UL 127, and UL
103HT - 2006. The EPA qualifying emissions tests were
conducted by OMNI-Test Laboratories Report No.: 257-F06-3.
EPA Phase 2 qualied Standard Series replace
systems are also designed for installation in accordance
with the National Fire Protection Association Standard
for chimneys, replaces, vents and Solid Fuel-Burning
Appliances (NFPA 211).
EPA Phase 2 qualied Standard Series replaces are not
listed for use with replace inserts.
WARNING:
This replace has not been tested for use with glass
doors. To reduce the risk of re or injury, do not install glass
doors.
Some jursdictions require the use of glass doors. If
glass doors are used, operate replace with doors in the fully
open position.

Safety Instructions
1. Before starting the EPA Phase 2 qualied Standard Series
replace and DM 54 chimney installation, read these installation
instructions
carefully to be sure you understand them completely. Failure to
follow them could cause replace malfunction resulting in serious
injury or property damage.
2. Always check local building codes governing replaces and
replace installations. The EPA Phase 2 qualied Standard Series
replace and DM chimney installation must comply with all local,
regional, state and national codes and regulations.
3. EPA Phase 2 qualied Standard Series replace and DM 54
chimney systems are intended for use in any application where
a traditional masonry type replace would apply. The chimney
system must always vent vertically to the outside of the building.
4. Creosote and soot formation and the need for removal: When
wood is burned slowly, it produces tar and other organic vapors
which combine with expelled moisture to form creosote. The
creosote vapors condense in the relatively cool chimney ue of a
slow burning re. As a result, creosote residue accumulates on the
ue lining. When ignited this creosote makes an extremely hot re.
Because of creosote and soot buildup it is necessary
to inspect and clean the replace and chimney prior to use and
periodically during the heating season. Cleaning of the replace
and the chimney system should be done annually at a minimum. In
colder climates, chimney cleaning may need to be done periodically
throughout the heating season.
5. Before servicing, allow the replace to cool. Always shut off
any electricity or gas to the replace while working on it.
6. Use only solid fuel or natural or LP gas log sets in this unit. Do
not use articial wax based logs, chemical chimney cleaners or
ame colorants in this replace.
7. Never use gasoline, kerosene, gasoline-type lantern fuel,
charcoal lighter uid, or similar liquids to start or “freshen up” a
re in this replace. Keep all ammable liquids at a safe distance
from the replace.
8. Always keep the ue damper open when heat is present in the
replace.
9. Do not use a replace insert or any other product not specied
for use with the EPA Phase 2 qualied Standard Series replace
and DM 54 chimney systems unless written authorization is given
by Isokern. Failure to heed this warning may cause a re hazard
and will void the Isokern warranty.
10. This replace is not intended to heat an entire home or to be
used as a primary heat source. It is designed to ensure homeowner
comfort by providing supplemental heat to the room.
11. Always ensure that an adequate supply of replacement
combustion air from the outside of the house is accessible to
the re to support normal combustion. Fireplaces consume large
volumes of air during the normal ring process.
In the event the home is tightly sealed and has modern
energy efcient features, the optional combustion air supply kits
may not provide all the air required to support combustion and the
proper ow of combustion gases up the chimney.
The manufacturer is not responsible for any smoking
or related problems that may result from the lack of adequate
air supply owing into the house. It is the responsibility of
the builder/contractor to ensure that adequate air supply has
been provided for the replace.
12. “Smoke free” operation is not warranted nor is the
manufacturer responsible for inadequate system draft caused
by mechanical systems, general construction conditions,
inadequate chimney heights, adverse wind conditions or
any unusual environmental conditions or factors beyond the
manufacturer’s control.
Caution: When used with the EPA Phase 2 qualied Standard
Series replace system, all gas log sets must be operated with
the damper clamped in the fully open position. This includes
unlisted “vent free” log sets. Only listed “vent free” log sets
may be operated with the damper in the closed position.
13. When in doubt about a component’s usability - has
visible or suspected physical damage - consult your Isokern
distributor or authorized Isokern representative for advice.
14. Modication to STANDARD components not mentioned
in this manual may void claims, listings and approvals
and could result in an unsafe and potentially dangerous
installation.
Alterations to the STANDARD rebox are allowed
with prior written approval and instructions from Earthcore
Industries, LLC. The installer indemnies the manufacturer
of all claims and under no circumstances will manufacturer
be liable for consequential, incidental, indirect, punitive or
other damages of any kind or nature, whether foreseeable or
not, based on any claim by any party as to the modications
of the Isokern replaces.
15. Wherever insulation is used, the EPA Phase 2 qualied
Standard Series replace must not be placed directly against
it. Keep all insulation or vapor barriers a minimum of three
inches (3”) away from all replace and chimney components.
It is recommended that insulation and vapor barriers, if used,
rst be covered with gypsum board, plywood, particle board
or other material to assure that insulation and vapor barriers
remain in place.
WARNING: Do not pack required air spaces with insulation
or other materials.
16. Never leave children unattended when there is a re
burning in the replace.
17. Burning some fuels (such as charcoal) can be hazardous
due to the possibility of producing carbon monoxide, a
colorless, odorless gas. Early signs of carbon monoxide
poisoning resemble u symptoms, including headaches,
dizziness or nausea. Over exposure to carbon monoxide
can lead to illness and death. It is strongly recommended to
install smoke and carbon monoxide alarm / detector devices
wherever replaces are in use.

Catalytic Combustor system Operation
The proper use of a wood burning replace equipped with the Catalytic Combustor system will signicantly reduce the
emissions that it produces. Simple fuel considerations with regard to moisture content, size, and quality of fuel will help control the
production of wood smoke and ultimately improve the performance of the Catalytic Combustor system and replace efciency. With
proper care, the Catalytic Combustor system will provide years of fuel savings and lowered emissions. By following some simple
guidelines, you will ensure maximum performance and longevity.
The smoke that is usually seen coming out of a chimney is essentially a combination of unburned fuel (carbon and hydrogen)
and moisture in the form of water vapor. The Catalytic Combustor system is a technology that provides secondary combustion for
the wood burning process.
Avoid the use of treated, painted and laminated wood. Never incinerate garbage or other foreign materials. Do not use
articial logs, colored newspaper or petroleum based re starters. Avoid wood with high salt content. All of these materials may
contain compounds which can shorten the life of the catalyst. Wet or unseasoned wood may lower catalytic temperatures and result
in inefcient operation.
The Catalytic Combustor system is designed to function at optimum efciency when the replace is burning clean, dry
cordwood as replace fuel. A simple visual inspection of the chimney during the wood burning process will determine catalytic
performance.
NOTE: Chimney smoke may be visible during the rst 8-10 minutes of replace operation when the re is rst started and also
during the nal 8-10 minutes of operation when the re in the replace is going out. Otherwise, the catalytic system will eliminate
approximately 90% of the visible chimney smoke typically produced by a wood burning replace.

Assembly Instructions - Isokern Standard & Magum Models
NOTE:
General Isokern Assembly Instructions
Magnum 86072 Model:
Refer to Magnum Model 86072, 60 & 72 Installation,
Operation & Owner’s Manual found with the palletized
components or online at: www.earthcore.co
General Isokern Assembly Instructions:
Earthcore Mortar (a thin-set type masonry adhesive) is used
to glue all Isokern components together during eld assembly of the
unit. The mortar is supplied dry, in either 15 pound or 50 pound pails.
Earthcore mortar is mixed with clean water to a smooth,
workable texture (without lumps or dry pockets) of a “toothpaste”
consistency. This mixture is suitable for application onto Isokern
components by using a masonry grout bag supplied with the unit.
Attention should be paid that the mortar mixture is not too
thin or runny, as this will not allow the mortar to reach its maximum
bonding strength.
Earthcore mortar is squeezed from a grout bag onto the
contact surfaces of the Isokern components as they are tted together.
It is important that a 1/2” bead of mortar on all the
components’ contact surfaces is applied at about 1/2” in from all
edges of the contact surface of the component.
When setting the next component onto the mortared contact
surface of the rst component, some mortar should squeeze out along
the face of the entire joint as a sign of complete and proper sealing of
the joint.
On broader contact surfaces it is advisable to apply several
additional 1/2” beads of the Earthcore Mortar to the area to assure
proper sealing of the joint.
Properly mortared rebox and smoke dome assembly
requires approximately 25 pounds (dry measure) of Earthcore mortar.
Broken Components:
Components broken into 2 or 3 pieces can be repaired by
using Earthcore mortar along the break line as the component is set
into place. Components broken into multiple small pieces should be
discarded and replaced.
Leveling and Aligning Components:
Be sure to assemble all Isokern components level and ush
with adjoining components.
Earthcore mortar is not intended to create a mortar joint
of any thickness for leveling purposes. Therefore, leveling and
alignment adjustments are made by the use of small plastic shims
supplied with the unit.
The shims can be inserted under a component to level and
align it with adjacent Isokern components. Be sure to re-grout any
and all gaps resulting from shim insertion to maintain components to
full bearing.
Notes:
1. Do not mix Earthcore mortar with spirits or anti-freeze agents.
2. The maximum recommended mortar joint thickness at Isokern
components is 1/4”.
3. Earthcore mortar can be troweled over the face of a joint where
it has squeezed out while setting components. It is not intended that
the exposed faces of the Isokern components be completely covered
with the mortar.

Assembly Instructions - Isokern Standard & Magum Models
Installation:
Step 1: Set the EPA Phase 2 qualied Standard Series replace
base plate in a full bed of Earthcore Mortar at on a proper
concrete support foundation. Do not set the base plate so that it is
in span. Level the base plate by oating it in a bed of Earthcore
Mortar to full bearing against the underlying noncombustible
support surface.
Note: The bottom of the sidewall has a slightly smaller opening
than does the top (meaning when the sidewalls are made – the
board side of the sidewall has about a 1/8” narrower opening than
does the top. If the replace is stacked where the top sidewall is
placed upside down the clip will have a slight interference when
attempting to install. If this occurs, scrape away an area about
1.5” wide by the 1/8”.
Note: If the design preference is for a “ush hearth” (replace
oor ush with the room’s oor), the base plate can be omitted
from the assembly and the rebox walls built directly on the
concrete support slab. The re brick oor of the rebox is then
set directly to the concrete support slab. This makes the replace
nished re brick oor approximately one and one-half inches
(1-1/2”) above the top of the concrete support slab.
If the design preference is for a raised hearth (oor of
the replace elevated above the room’s oor), then the base plate
can be set on a noncombustible platform that is built up to the
desired raised hearth height on the concrete support slab.
When calculating raised hearth height be sure to allow
for the three inch (3”) thick base plate plus the one and one
half inch (1-1/2”) thick re brick oor in addition to the height
of the platform. Whether a ush hearth is preferred or a raised
hearth, the combustible oor on front of the replace must be
covered with a noncombustible hearth extension set tight against
the replace front and extending at least 20 inches out from the
nished replace and at least 12 inches beyond the nished sides
of the replace opening.
For all “raised hearth” construction where concrete
blocks are used to create the raised platform, it is necessary to
use the base plate. Be sure to mortar the concrete block platform
together. CMU used for base plate support should be rated ASTM
90.
Note: At all component placement, be sure to mortar all compo-
nent contact surfaces with Earthcore Mortar. Check for complete
sealing of each contact joint while assembly progresses.

Assembly Instructions - Isokern Standard & Magum Models
Step 2: Set the rst course of the rebox back wall and side walls
into place.
It may be convenient to dry set the rst course of side
wall and back wall into place on the Isokern base plate and then

to trace their position on the base plate with a pencil.
After outlining the dry set pieces, remove them and
apply Earthcore Mortar to the areas traced on the base plate
where the side walls and back wall are to sit. By doing this, the
rst layer of wall components can be set directly into mortar
already applied to the proper areas on the base plate.
Be sure to put Earthcore Mortar on the contact surfaces
of the vertical joints where the side wall and back wall
components connect.
Step 3: Continue assembly of the second, third and fourth courses
of the rebox side wall and back wall. Apply mortar to the top
of each layer of wall components, set the next course above into
place. Be sure to mortar all vertical joints of the side wall to back
wall connection when setting each component to its mate.
Look for some mortar to squeeze out along the joints of
all contact surfaces as a sign that the joint is thoroughly sealed
with the approved mortar.
Step 4: When all of the rebox wall components are set, check
the top surface of the rebox for level. If necessary, adjust the top
surface of the box assembly for level by inserting a shim between
the lowest wall component and the top surface of the base plate.
Any gap created under the wall components during the
Shim leveling process must be lled with mortar to full bearing
against the base plate.
Top Course
Back Wall
Step 5: Make sure that the rebox assembly has been set level
and square. Adjust as required while the mortar is still wet.
Make a nal inspection of all contact joints in the
rebox assembly to be sure they are properly sealed. Fill any and
all gaps in the assembly, as necessary, with the approved mortar.
Step 6: Take the Catalytic assembly out of the box and verify all
components are in tact and Yellow EPA hangtag is attached to the
combustor. The Catalytic kit should contain a Catalytic
Combustor, and two (2) metal angle support brackets.
Note: Remove hangtag from combustor and place in a secure,
permanent location. Retention of this hangtag by the owner of
the replace is mandatory. If ownership changes, hangtag should
be given to the new homeowner.
Earthcore Mortar
Step 7: Insert support brackets so that the largest angled portion
slides into the side wall cavity toard the front of the sidewall
slots. The smaller angles should be facing upward toward the
inside of the rebox.
16
Assembly Instructions - Isokern Standard & Magum Models
Step 8: Center the Catalytic Combustor in the rebox and rest
it on top of the support brackets making sure that the lter is
equally settled on the brackets. The lter should be set toward
the rear of the rebox.
Step 9: If grouting the inside of the sidewalls, leave the top 1
3/4” without grout or else measure and locate the mounting
clip to the exact dimension (based on the thickness of the brick
& mortar used to line the inside of the rebox backwall).
Step 10: Set the back smoke dome component across the rear
side walls in a bed of mortar and ush with the back face of the
back wall.
Set the front smoke dome component in mortar across
the front side walls ush with the front of the sidewalls.
Step 11: Position the smoke dome’s sloping sidewalls at each
end of the smoke dome components.
The sloping sidewalls t in between the front and rear
smoke dome components and also t into the haunches at the
ends of the front and rear smoke dome components. Mortar all
contact surfaces thoroughly.
Note: The smoke dome sloping sidewalls have a beveled
bottom edge so that they will sit tight onto the at top of the
side walls.
Step 12: Make sure that all component contact surfaces have
been properly sealed with approved mortar.
Check smoke dome front and back walls to see that
they are plumb, level and in alignment with mating components.
Check alignment of the smoke dome sloping sidewall
components to see that they are fully seated.
Step 13: Set the smoke dome top plate into position on top of
the smoke dome wall assembly.
One side of the smoke dome top plate shows a
thickened center. This side is the bottom face of the top plate.
The fourteen inch (14”) diameter ue hole in the top
plate is centered in the smoke dome from side to side but is
offset from front to back.
Make sure that the top plate is set so that the ue hole
is closer to the back wall of the smoke dome assembly.
Be sure to set the smoke dome top plate ush with the
front, back and sides of the smoke dome assembly. All contact
surfaces must be properly sealed with the approved mortar.
Note: The completed smoke dome assembly should present a
stable and level surface for setting the ue components.

Assembly Instructions - Access Modication
Through-Wall Accesses:
1. Combustion Air Inlet: Combustion air inlet kits though not required
by Isokern may help improve replace operation in homes tightly sealed
and with other ventilating appliances installed. Check local codes for
combustion air inlet requirements.
The following is a general representation of a generic
combustion air kit and not a requirement of Earthcore Industries,
LLC. Local building codes prevail and should be checked before
installation.
Generic replace combustion air kits typically consist of a sliding
stainless steel access door afxed to a three inch (3”) or four inch (4”)
diameter stainless steel sleeve approximately twelve inches (12”) long.
An exterior vent with dress plate, weather hood and rodent prevention
screen of a maximum one-quarter inch (1/4”) wire mesh completes the
kit. (Figure 20)
The access door is tted into the nished re brick lining at the
interior sidewall of the rebox. The twelve inch (12”) long sleeve can
be introduced into the rebox side wall or back wall by core drilling an
appropriately sized hole at the selected rebox location. Keep the top of
the four inch (4”) diameter access hole no more than six inches (6”) above
the nished rebrick oor. The hole size should allow for a one-quarter
inch (1/4”) mortar joint around the air access sleeve for heat expansion.
The sleeve passes through the rebox wall and must
be connected to metal pipe (by other) - either exible or rigid - that leads
to the source for outside combustion air, as directly as possible from the
EPA Phase 2 qualied Standard Series replace (Few to no bends) with a
maximum length of sixty feet (60’).
WARNING: Do not use combustible duct material. Avoid installing a
combustion air inlet where the opening could be blocked by snow, bushes
or other obstacles. Air inlet must terminate a minimum of three feet below
the chimney cap level. Air inlet ducts shall not terminate in attic spaces.
2. Gas Line Feed: For a replace having the provision for installation of
a gas pipe, the provision is intended only for connection to a decorative
gas appliance.
CAUTION: When using the decorative appliance, the replace damper
must be set in the fully open position.
Gas line for gas log sets used in the Isokern rebox can be routed
through the side wall, back wall or oor of the rebox by drilling an
appropriately sized hole using a masonry drill bit.
3. Electrical Line Feed can be routed through the rebox back wall, side
walls or oor by drilling an appropriately sized hole using a masonry
drill bit. Be sure to follow the gas log appliance manufacturer’s explicit
electrical line connection instructions for vented replace installations.
Gas line and electric line must be fed through separate access
holes.
CAUTION: All access holes must be grouted with mortar – after line or
conduit feed - to seal any gaps or cracks around line feed conduits.

Fire Brick Installation Isokern Standard & Magnum
Fire Brick Installation:
The manufacturer requires that the EPA Phase 2
qualied Standard Series replace rebox be lined with a
minimum one and one-eighth (1-1/8”) thick rated re brick.
The pattern for the re brick lining is an owner option. Standard
N-Type brick mortar is a suitable re brick mortar for the EPA
Phase 2 qualied Standard Series replace and good masonry
practices should be followed.
All required through-wall accesses (gas and electrical
line feeds and combustion air supply access holes) should be
drilled before the required re brick lining is installed.
It takes a total of about ve gallons of N-Type brick
mortar mix (dry measure) to re brick line a replace.
Face joints of one quarter inch (1/4”) to three-eights
inch (3/8”) give a good appearance to the nished brickwork
however, this is just a suggestion and other face joint
dimensions are also acceptable.
FIREBRICK FLOOR
AND BACKWALL
(BUILT FIRST)
Step 1. Wet mop the inside of the EPA Phase 2 qualied Standard
Series replace with a damp sponge to remove dust and loose
particles from the interior before installing re brick.
Step 2. Start the re brick at the front edge of the oor of the
Isokern rebox, proceeding inward toward the back.
HINT: Dip each rebrick into water before applying.
Step 3. Next, apply re brick to the back wall of the unit starting
at the bottom of the back wall and working upward to the top
of the back wall.
Step 4. Finally, set the side wall re brick by starting at the front
edge of the unit’s side wall and working inward toward the back
wall re brick.
Isokern makes no claims as to the performance
of re brick or re brick mortar(s). It is typical for heat
stress cracks to appear in the re bricks in wood burning
replaces.

Fire Brick Installation, Magnum 86072
Fire Brick Installation:
The manufacturer requires that the Magnum 86072
reboxes be lined with a minimum one and one-eighth (1-1/8”) thick
re brick on the back and oor of the rebox and four-inch (4”)
on the side walls. Thicker re brick may be used as an option. The
pattern for the re brick lining is an owner option. Standard N or S
type brick mortar is suitable mortar for the replace.
Fire brick mortar needs to be suitable to both adhere the
re brick to the inside of the rebox and to create the nished face
joints of the brick work. Based on a history of eld applications and
experience, a suitable mortar would be as follows:
Mix:
* 1/2 bag EC mortar or Six parts masonry mortar (S or N type)
* Six parts sand
* One part Fire Clay (optional)
* Water to a sticky, toothpaste consistancy
Because of different climates, the use of good masonry practices for
your area should also be considered.
It takes about 50 lbs. of mortar mix (dry measure) to re-brick line a
Magnum 86072 replace.
Installation Instructions:
1. Wet mop the inside of the replace with a damp sponge
to remove dust and loose particles from the interior before re-
bricking.
HINT: Dip each rebrick into water before applying.
2. Face joint dimensions of 1/4” to 3/8” in the brick work
is recommended and has the best appearance. Other face joint
dimensions are acceptable however smaller joints may not leave
room for heat expansion of re brick.
3. Start the re brick at the front edge of the oor of the
Isokern rebox, proceeding inward toward the back. Let the oor
brick gap approximately 1/2” off the back wall and side walls. This
air space allows heat expansion of the re brick and is to be left
empty of mortar. (Figures 8 & 10)
4. Next, apply re brick to the back wall of the unit. The
back wall re brick covers the 1/2” expansion gap left at the brick
oor along the back wall of the rebox. (Figure 9)
5. Set the side wall re brick by starting at the front edge
of the unit’s side wall and working inward toward the back wall
re brick. The side wall re brick, when completed, covers the 1/2”
expansion gaps where both the oor re brick and the back wall re
brick were held off the units side walls. (Figure 10)
All required through-wall accesses (gas and electrical line
feeds and combustion air supply access holes) should be drilled
before the required re brick lining is installed.
Isokern makes no claims as to the performance of re
brick or re brick mortar(s). It is typical for heat stress cracks to
appear in the re bricks in wood burning replaces.

Summary
1. WARNING:
Fireplace and chimney systems will only draught
properly when they are installed according to the instructions,
in an appropriate location and with the proper chimney height.
Installing the replace according to the instructions, choosing an
appropriate location, and choosing an appropriate chimney height
are the responsibility of the designer and the building contractor.
Tightly insulated and sealed homes, two story interior
spaces and high vaulted ceilings can cause negative air pressures
within the house which can impair drafting performance. HVAC
return air ducts near the replace opening will adversely affect the
replace drafting performance.
It is the responsibility of the designer, the building
contractor and their mechanical contractor to determine that the
building’s internal air pressures are conducive to positive replace
drafting.
Avoid placing any replace in an area near tall trees,
tall buildings, or high land masses. These structures can reduce
ambient air ow pressure as well as produce down draughts,
either of which can impair replace drafting performance.
Earthcore Industries L.L.C. does not warrant drafting
and is not responsible for it.
2. EPA Phase 2 qualied Standard Series replace and FireLite Fireplace Curing Instructions:
It is critical that the Isokern masonry elements in the
rebox and smoke dome assembly be dry before ring of the unit.
Moisture left in the components from exposure during storage and
shipping, as well as moisture from the installation phase, must be
eliminated before the unit is put to its intended use.
The rst step in reducing the ambient moisture is to be
sure that the completed replace rest totally in a dried-in setting for
a minimum of 28 days after construction of the unit is complete.
The next step in curing the replace is to be sure that the
rst ve or six res are of short duration.
The rst re of the unit can take place once the minimum
twenty-eight day drying period has passed. This re should be
especially short.
Start the rst re slowly with a small amount of paper
and kindling (small dry wood splits or twigs) and a maximum
load of four to six pounds of dry rewood, estimated to be no
more than two or three logs each of about three inches (3”) to four
inches (4”) diameter.
The rst re should burn for no more than thirty to sixty
minutes and then allowed to go out. Do not refuel the replace
during the rst lighting.
A cooling off period of twenty-four hours, at a minimum,
should follow the rst re.
The second re should be the same as the rst re.
The second re should burn for no more than thirty to
sixty minutes and allowed to go out. Do not refuel the replace
during the second lighting.
A twenty-four hour cooling off period must be
observed following second lighting.
After the rst and second re, continue use of the
unit with three or four small res of short duration (sixty
minutes or so) and small fuel load.
After these rst ve or six small res of short
duration normal use of the replace can proceed. For normal
use the maximum recommended fuel load is twelve to sixteen
pounds of dry rewood at a time. This fuel load is considered
to be approximately three to ve cured hardwood logs of
about three inches (3”) to six inches (6”) in diameter. As the
re burns down, refueling should be only one or two logs
added at a time.
Important: Do not burn construction debris or trash of any
kind in the Fire-Lite replace.
Whereas it is not uncommon for construction debris
and refuse to be burned in a replace by site personnel on
a project that is under construction, this activity must be
avoided.
It is the responsibility of the building contractor
to insure that the required dry-in period is met and that the
required lighting sequence is performed by the owner or by
the owner’s agent.
3. Log grates are required for burning solid fuel in the
Isokern replace. Grates allow for easy air ow up through
the burning logs thus creating a more complete and efcient
burning of the fuel.
4. How to Build a Fire:
First set the replace damper in the full open position.
Begin laying the re by placing several pieces of wadded up
paper directly on the log grate. Place kindling (small splits of
dry pine or other dry softwood) on top of the paper, enough
to loosely cover the paper. Next arrange several small, dry
hardwood or softwood logs or log splits on top of the kindling
layer.
Finally, arrange two or three larger hardwood logs
(oak, hickory, etc.) or log splits on top of the stack. Ignite the
paper at the bottom of the stack. The burning paper will ignite
the kindling which will, in turn, set the remaining fuel on re.
Be sure to stack all rewood in such a way that it will
settle into the log grate as the paper and kindling layers are
burned away. Additional logs can be set onto the re as each
fueling burns down.
Ideally, fuel logs should be of a hardwood species
that have been air dried for one year or longer. Use of cured or
uncured pine logs and uncured hardwood logs for fuel should
be avoided. Pine logs and uncured hardwood logs will tend
to smolder and burn at relatively low temperatures producing
high levels of soot and creosote.
Important: Do not throw, toss, jam, kick or otherwise force
logs into the replace.
22
Summary
WARNING:
Never use gasoline, gasoline type lantern fuel,
kerosene, charcoal lighter uid or other similar liquids to start
or “freshen up” the re in this replace or in any replace.
WARNING:
If processed solid fuel relogs are used: Do not poke
or stir the logs while they are burning. Use only relogs that
have been evaluated for the application in replace and refer
to relog warnings and caution markings on packaging prior to
use.
5. Avoid over-ring this replace. Some examples of overring are:
a. Burning of scrap lumber, construction debris, pine branches
and brush or cardboard boxes;
b. Burning small diameter twigs, branches or any other small
sized combustible materials in quantities which exceed the
volume of the normal log re;
c. Use of articial wax base logs, trash or other chemicals or
chemically treated combustibles.
WARNING: Over-ring can permanently damage this
replace system.
6. Fireplace Doors and Screens:
This replace has not been tested for use with doors.
To reduce the risk of re or injury, do not install doors. If doors
are required by the local authority having jurisdiction then
doors must be kept in the fully open position when the replace
is in operation. Isokern does not limit the use of replace
screens.
7. Disposal of Ashes:
It is recommended that the rebox be cleaned of
excessive ashes before each use. It is necessary to remove
ashes from the open front of the replace. To do so, proceed in
the following manner:
Allow the re to go out and the ashes to cool for at
least six to eight hours.
After the cooling period carefully pick up the ashes
from the rebox with a small, metal replace shovel or other
metal scoop and place them in a metal container with a tight
tting lid.
If possible do not sweep the ashes as this will stir
them into the air and disperse them into the room.
The closed container of ashes should be placed on
a noncombustible oor or on the ground, well away from all
combustible materials, pending nal disposal. If the ashes are
disposed of by burial in soil or otherwise locally dispersed,
they should be retained in the closed container until all cinders
have thoroughly cooled.
8. Inspection and Cleaning:
At least twice a year in warm climates or monthly
during the heating season in colder climates, thoroughly
inspect the Fire-Lite replace and chimney system.
Chimneys must be installed so that access is provided for
inspection and cleaning. The chimney should be inspected
monthly during the heating season.
Inspect the entire ue from the top down for
obstructions such as birds’ nests, leaves, etc. Such obstructions
must be removed.
Check spark arrestor screens for clear ow of smoke
every two to four weeks during the heating season.
Inspect the ue periodically during the heating season
for the presence of soot and creosote build up. If creosote or
soot has accumulated, it should be removed to reduce the risk
of chimney re.
Have your chimney cleaned by a professional chimney
sweep if you have doubts about your ability to do it.
Use a plastic, wood or steel brush to clean the chimney.
Scrub the spark arrestor/chimney cap with a wire
brush.
Remove any chimney cap for ue cleaning from the
top. Open the damper in the rebox for cleaning access from
below.
Clean the inner portion of the ue by using a exible
handled chimney cleaning brush.
For straight run ue the proper size brush can be pulled
up through the ue from the rebox with the damper open.
If the chimney has an offset chimney section, brush
cleaning from the chimney top down to the offset/return and
then from the rebox up to the offset section is the proper
method.
In either case, cover the replace opening with a damp
sheet (sealed to the opening with masking tape) before brush
cleaning. Do not remove sheet until the soot has settled. It is
advised to vacuum loosened soot. Do not sweep loosened soot
as sweeping will disperse soot into the air and about the room.
WARNING: Do not use chemical replace and chimney
cleaners that are poured on a hot re. These can be dangerous
and generally work only on the ue section nearest the re,
leaving the rest of the ue unaffected.
9. Exterior Maintenance:
Annually, at a minimum, check all metal ashings and
weather seals around the exterior chimney where it penetrates
the roof surface; inspect any chimney top spark arrestors, metal
cowlings and weather hoods to make sure they are secure and
weather tight.
Seal any cracks or gaps in chimney-to-roof ashings
to prevent possible roof and chimney chase leaks.
Inspect any cement chimney cap or clay chimney pot
terminations to make sure they are not diverting water into the
structure. Seal any suspected cracks or gaps in these masonry
components.
