Required Clearance to Combustibles
Important: “Combustibles” are defined as “normal construction materials” and considered to be: wood framing materials, particle
board, mill board, plywood paneling, plywood subflooring and wood flooring.
The IBV is listed for installation with “clearance to combustibles” (shown below) as follows:
A: Zero inch (0”) clearance to the combustible floor; (Isokern Base Plate must be used)
B: Zero inch (0”) clearance at the Isokern firebox sides and front and smoke dome sides and front;
C: One and one half inches (1-1/2”) clearance at the Isokern firebox back wall and smoke dome back wall;
D: One inch (1”) minimum air space to combustibles at all B-Vent double wall chimney components’ outer layer.
(Contact pipe manufacturer for specific clearance information)
CAUTION: Maintain three inches (3”) clearance to insulation and vapor barriers from all firebox, smoke dome and B-Vent flue
components’ outer layer.
Notes:
1. The IBV is designed, tested and approved for installation directly on a combustible floor system per the installation specifications
given in this manual.
2. All IBV installations will result in the minimum finished fire brick floor of the firebox being at least four and one half inches
(4-1/2”) above the combustible floor system. For flush hearth installations, consult your local representative.
3. The combustible floor in front of the fireplace must be covered with a noncombustible hearth extension material set tight against
the fireplace front and extending at least twenty inches (20”) out from the finished front of the fireplace and at least twelve inches
(12”) beyond the finished sides of the fireplace opening (See page 28).

Combustible Floor System Loading
Important:
Floor framing for IBV installation will need to
be designed and built to accept substantial dead loads spread
over a relative small floor area. (Figure 1)
The following weights and sizes can be used to
calculate loading. It is the contractor’s responsibility to provide
adequate floor system load capacity.
IBV Weights and Load Calculations:
Total dead load amounts include (but are not necessarily limited
to) the following items and their corresponding weight estimates
as listed below:
1. Isokern unit model weights:
a. IBV-46: 1400 lb
b. IBV-36: 1200 lb
2. Approximate weight of log set: 100 lb.
3. Fire brick and mortar: 350 lb.
4. Facing material: per general contractor
5. B-Vent metal flue: per manufacturer
The floor area for each model is as follows:
IBV-46 @ 53” x 25.25” = 9.30 sq. ft.
IBV-36 @ 43” x 25.25” = 7.54 sq. ft.
Notes:
1. Earthcore is not responsible for structural floor support
details for this fireplace system. Unless otherwise noted all
floor framing drawings in this manual are merely illustrations
to indicate the presence of an underlying floor system.

IBV Assembly Instructions
General Assembly Instructions:
Earthcore Mortar (a thin-set type masonry adhesive) is
used to glue all IBV masonry components together during field
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 IBV components by using a masonry grout bag such as the
one 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
Earthcore Mortar is squeezed from a grout bag onto
the contact surfaces of the IBV components as they are fitted
together. (Figure 2)
It is important that a one-half inch (1/2”) bead of mortar
on all the components’ contact surfaces is applied at about onehalf inch (1/2”) in from all edges of the contact surface of the
component.
When setting a component onto the mortared contact
surface of the preceding 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 one-half inch (1/2”) beads of the Earthcore
Mortar to the area to assure proper sealing of the joint.
Properly mortared firebox and smoke dome requires
approximately 25 pounds (dry measure) of Earthcore Mortar.
Figure 2
Broken Components: Components broken into two or three
pieces can be glued together along the break line with Earthcore
Mortar 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
IBV components level and flush with adjoining components.
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
IBV components (Figure 3). Be sure to add mortar to all gaps
resulting from shim insertion.
Shim if required
to acheive
correct height
Figure 3
Notes:
1. Do not mix Earthcore Mortar with spirits or anti-freeze
agents.
2. The maximum recommended mortar joint thickness at IBV
components is one quarter inch (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 IBV components be completely covered
with the mortar.

IBV Assembly Instructions (cont.)
Assembly Steps for IBV firebox and smoke dome:
Earthcore
Mortar
Step 1:The IBV base plate can be set directly on a combustible
floor system. Set the base plate level in a bed of Earthcore Mortar
so that the base plate is in full contact with the underlying floor
system (Figure 4). Do not set the IBV base plate in span.
Raised and Flush Hearth Application:
Figure 4
For a “flush hearth” the IBV must be built upon a
concrete (noncombustible) support slab that has no wood
underpinnings. (Figure 5) For a “flush hearth” application
the IBV three inch (3”) thick base plate is omitted from the
assembly. The firebrick will then be mortared on the concrete
slab and the noncombustible hearth material will butt tight up
against it.
For a “raised hearth” (floor of the fireplace elevated
above the room’s floor) the IBV base plate can be set on a
structurally sound built up platform that is built to the desired
finished raised hearth height.
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 fire brick floor in addition to the height of
the field constructed raised platform. (Figure 6)
Flush Hearth
on Concrete
Foundations Only
WARNING:
“Flush hearth” installations are possible only where the IBV
support is a concrete slab without any wood underpinning
as the base plate is omitted. Never place an IBV on a
combustible floor without the base plate.

IBV Assembly Instructions (cont.)
Step 2: Set the first course of the firebox back wall and side
walls into place on the base plate. (Figure 7)
It may be convenient to temporarily dry set the first
course of side wall and back wall into place on the IBV base
plate and then to trace their position on the base plate with a
pencil.
Remove the dry set pieces 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 first 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. (Figure 8)
Step 3: It is required that the two supplied high temperature
wires be routed from the inside of the IBV as follows:
Once the lowest, left hand side wall firebox component
is set in place (left, when facing the fireplace) drill a 1/4” - 3/8”
dia. hole in the inner face of this side wall located four to six
inches (4” - 6”) out from the back wall of the IBV and at three
to four inches (3” - 4”) above the IBV base plate. (Figure 9)
This drill hole must intersect the hollow core
of the IBV firebox side wall.
Feed the two lengths of high temperature wire from
the inside of the IBV firebox through the drill hole and into
hollow space of the firebox side wall. Bring the two lengths
of wire up and out through the top of the side wall component
(Figure 9).

Step 4: Continue assembly of the second and third courses of
the firebox side wall and back wall. Apply Earthcore Mortar
to the top of each layer of wall components, then set the next
course above into place.
Be sure to apply mortar to all vertical joints of the side
wall to back wall connection when setting each component to
its mate. (Figure 9)
Look for some Earthcore Mortar to squeeze out along
the joints of all component contact surfaces as a sign that the
joint is thoroughly sealed with mortar.
Continue to feed the two high temperature wires up
through the hollow core of the left hand sidewall stack.
Be sure to leave approximately four feet (4’) of each of
the two high temperature wires out of the top of the left hand side
wall of the firebox for later connection to the high temperature
limit switch and also four feet (4’) of each wire loose inside the
firebox for later connection to the pilot assembly. (See wiring

Step 5: Once all the firebox wall components are set check the
top surface of the firebox for level.
Step 6: Begin the smoke dome assembly by setting the rear
bottom smoke dome component on top of the firebox back
wall assembly in a bed of Earthcore Mortar. The smoke dome
component should sit flush with the back side of the firebox
assembly. (Figure 10)
High Temperature
Wire (2 pc. / 12’ long)
Figure 10
Step 7: Set the front bottom smoke dome component across the
firebox opening so that the smoke dome piece spans the firebox
opening and is flush with the front of the firebox.
Step 8: Position the smoke dome’s sloping sidewalls at each
end of the bottom smoke dome components (Figure 11).
The sloping sidewalls fit in between the front and rear
smoke dome components and also fit into the haunches at the
ends of the front and rear smoke dome components.
The smoke dome sloping sidewalls have a beveled
bottom edge so that they will sit tight onto the flat top of the
firebox side walls.
Step 9: Set the upper course of front and rear smoke dome
components directly on top of and aligned with the bottom front
and bottom rear smoke dome components that are already in
place.
Set the two upper smoke dome sloping sidewalls into
position, one at each end of the upper front and rear smoke
dome components. (Figure 12)
Figure 11
Step 10: Ensure that all component contact surfaces have been
properly sealed with Earthcore Mortar.
Check smoke dome front and back walls to see that they
are plumb, level and in alignment with adjoining components.
Check alignment of the smoke dome sloping sidewall
components to see that they are flush with one another and
create smooth and uniform smoke dome Sidewalls for the total
height of the smoke dome.
Step 11: Set the smoke dome top plate into position on top of
the smoke dome wall assembly, with the flue hole closer to the
rear. (Figure 12)
Be sure to set the smoke dome top plate flush with the
front, back and sides of the smoke dome assembly.

IBV Assembly Instructions (cont.)
Access Modification:
1. Gas Line Feed: These provisions for installation of a gas pipe is only
for connection to the included ISOFLAMES decorative gas log set. The
ISOFLAMES decorative gas log set incorporates an automatic shutoff
device and complies with the Standard for Decorative Gas Appliances
for Installation in Vented Fireplaces, ANSI Z21.60. The ISOFLAMES
decorative gas log set should be installed in accordance with the
ISOFLAMES Gas Log installation manual (pages 30 through 37) and
per the National Fuel Gas Code, ANSI Z223.1.
The gas line for the ISOFLAMES gas log set used in the IBV
firebox should be routed through the left side wall of the firebox (left,
when facing the unit) by drilling an appropriately sized hole using a
masonry drill bit (Figure 13).
CAUTION: Avoid the high temperature wire when drilling gas line
hole.
Typical placement of
gas or electric line
(see detail below)
Notes:
1. Gas Line and Electric Line must be fed through separate access
holes.
2. Combustion Air Inlet: Combustion air inlet kits though not required
for IBV may help improve fireplace operation. (Figure 14 & 15). Check
local codes for combustion air requirements.
The access door is fitted into the finished fire brick lining at
the interior of the IBV firebox. The twelve inch (12”) long sleeve can
be introduced into the firebox right hand side wall by core drilling an
appropriately sized hole through the right-hand side wall keeping the
hole two inches (2”) above the rough floor of the firebox. (Figure 13)
The hole size should allow for a one quarter inch (1/4”) mortar joint
around the air access sleeve. The sleeve passes through the firebox wall
and must be connected to metal pipe - either flexible or rigid - that leads
to the source for outside combustion air, maximum length sixty feet
(60’). Maintain clearance of at least two inch (2”) to air kit sleeve as it
exits the outer surface of the IBV side wall.
All access holes must be grouted with mortar - after line or
conduit feed - to seal any gaps or cracks around line feed conduits (Figure
15).

Fire Brick Installation:
The manufacturer requires that the fireplace fireboxes be lined
with a minimum one and one-eighth (1-1/8”) thick fire brick.
Thicker fire brick may be used as an option. The pattern for the
fire brick lining is an owner option. Standard N or S type brick
mortar is suitable mortar for the fireplace.
Fire brick mortar needs to be suitable to both adhere
the fire brick to the inside of the firebox and to create the
finished face joints of the brick work. Based on a history of
field applications and experience, a suitable mortar would be as
follows:
Mix:
* 1 bucket masonry mortar (S or N type)
* 5 lbs Earthcore mortar
* Six parts sand (1 1/2 bucket)
* One part Fire Clay (optional)
* Water to a sticky, toothpaste consistancy
Do
These instructions may vary because of different
climates and conditions. The use of good masonry practices for
your area should also be considered. It takes about 25 lbs. of
mortar mix (dry measure) to fire brick line a fireplace.
All required through-wall accesses (gas and electrical
line feeds and combustion air supply access holes) should be
drilled before the required fire brick lining is installed.
Face joints of one quarter inch (1/4”) to three-eights
inch (3/8”) give a good appearance to the finished brickwork.
However, larger face joint dimensions are also acceptable.
Step 1. Wet mop the inside of the IBV with a damp sponge
to remove dust and loose particles from the interior before
installing fire brick.
Note: It is a good practice to dip each brick in water before
installing.
Step 2. Start the fire brick at the front edge of the floor of the
Isokern firebox, proceeding inward toward the back.
Step 3: Apply C-clamp warning label to center floor brick prior
to mortar, ensuring verbiage is legible from front of firebox.
(Figure 16)
Step 4. Next, apply fire 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 5. Finally, set the side wall fire brick by starting at the front
edge of the unit’s side wall and working inward toward the back
wall fire brick.
Figure 16
Important: Be sure to bring the two high temperature wires
through the lower left hand side wall finished fire brick. The
two high temperature wires need to be accessible for later
connection to the high temperature limit switch wires.

IBV Assembly Instructions (cont.)
Metal Canopy Installation:
The metal canopy, as supplied, is forty five inches
(45”) long and fits the IBV models 36 & 46. Field cut the metal
canopy equally at the perforated lines as required for the 36”
unit. This will ensure the limit switch and micro-switch are
located in the proper position on the lintel.
Connect the two (2) leads from the high temperature
wires to the thermocouple junction block (see diagram, page
29).
Measure and locate the centerline of the fireplace
opening. Align notch at the front of the lintel to the centerline
of the fireplace. Install lintel using 1 1/2” masonry screws.

are attached to the limit switch with ceramic wire nuts.
The small tab near damper lever should be bent
upward to stand vertical. This protects wires passing through
the harness.
Figure 17
WARNING: Do not bypass the high temperature limit switch.
Install downdraft diverter at the top plate. (Figure 20)
Orient assembly such that the wire cable is toward the
front of the fireplace opening.
Loosen screws on the cable clamp and loop between
the two washers at the end of the handle asembly.
Note: Wire clamp should be approximately 4” from the washers.
Tighten lock nuts on the handle if necessary.
Pull cable to close the damper and adjust the length
of wire cable by swinging the handle between open and close
positions. When in the open position, the damper should be
rotated a full 90 degrees from the closed position.
Retighten screws on the cable clamp and remove
excess cable.
The metal canopy fits horizontally up toward the
bottom of the smoke dome. The adjoining short leg of the
metal canopy fits up against the bottom of the smoke dome
component. (Figure 19)
The metal canopy has 4 pilot holes for the screw placement. Attach the metal canopy flush against the front face of
the smoke dome with 4 mounting screws driven into the face of
the IBV smoke dome.
Any excess wire draped between the metal canopy and
the left hand firebox sidewall should be neatly tucked into the
hollow core of the left hand sidewall. Excess wire should not be
visible below the canopy bottom.
The 2 high temperature wires inside of the IBV firebox
will connect to the appropriate contacts found on the gas log
assembly during the installation of the gas log set.

Venting Installation
Anchor Plate/ Damper Installation:
Cut a twelve inch (12”) diameter hole in the center of
the ceramic fiber blanket which is then placed on the top plate,
aligned with and centered on the flue hole in the top plate.
The IBV anchor plate assembly is then dropped into
the hole in the top plate so that the conical shaped down draft
diverter / in-line damper assembly hangs down into the smoke
chamber (Figure 20).
When properly installed the wire cable is toward the
the front of the fireplace.
The mounting flange connects to the IBV top plate
by setting four screws (one and one-quarter inch (1-1/4”)
galvanized drywall screws) through the flange, through the
ceramic fiber blanket and into the IBV top plate.
To install B-Vent piping, slide the first piece of ten inch
(10”) inside diameter B-Vent pipe over the IBV starter collar
and attach with either two screws or other means approved by
the vent
manufacturer.
Actual installations will vary due to individual job
requirements. However, always maintain required clearances to
combustible materials and do not violate any specific B-Vent
installation requirements - ANSI Z223.1 / NFPA 54. Check
with the B-Vent manufacturer regarding specific clearances.
Be sure that in every case where offsets are used that
they are properly supported and that fire stops are used wherever
the vent passes through a sub-floor, ceiling joist ystem or an
attic overhang.
The vent pipe must terminate with a listed type vent
cap and extend through an approved roof flashing, roof jack or a
roof thimble vertically through the roof. Be sure to maintain the
listed clearances at all points of the vent system installation.

Venting Installation (cont.)
The IBV, per ANSI-Z21.50 standard, requires double wall, gas only BVent metal piping for the purpose of venting the appliance to the outside
of the building.
Specifications:
Gas code requirements concerning B-Type vent installations may
vary within state, province or local code jurisdictions. Therefore it is
recommended that you check with local building codes prior to installing
any B-Vent piping for specific requirements or, in the absence of local
codes follow Section 7.0 of the current National Fuel Gas Code ANSI
Z223.1, NFPA 54.
1. The IBV must be vented vertically out the top of the unit.
2. All B-Vent flue used with IBV must terminate vertically through the
roof.
3. All B-Vent flue used with IBV may not be terminated into an attic
space.
4. The B-Vent flue used with IBV must only be used for the IBV and not
shared with other venting systems.
5. Maintain a minimum one inch (1”) air space at all double wall B-Vent
metal pipe components.
100” minimum
6. Maintain a minimum two inch (2”) air space at all single wall B-Vent
metal pipe components.
Note: Check with pipe manufacturer for specific clearance
requirements.
45º
maximum
angle
7. Maintain a minimum three inch (3”) air space to all insulation and
vapor barriers.
8. Minimum required chimney height is one hundred inches (100”).
(Figure 21)
9. Maximum chimney offset angle is forty-five degrees off of vertical.
(Figure 21)
11. Only one offset per chimney system is allowed.
CAUTION: Do not modify or alter metal flue or metal flue components
as this could result in an unsafe and potentially dangerous installation
that may cause a serious injury. Consult B-Vent manufacturer.
Figure 21

Venting Installation (cont.)
Mechanical Vent Systems:
It is acceptable to use mechanical draft systems, if the venting
companies do the engineering calculations and make the
necessary recommendations for fan size and flue vent diameter
following the guidelines of NFPA 211/2006, pg. 211-13.
Installation of such systems must also follow the mechanical
drafting company’s explicit installation and operation
instructions.
The B-Vent type chimney system must be enclosed within a
chase when installed in or passing through a living area where
combustibles or people may come in contact with it. This is
important to prevent possible personal injury or fire hazard.
Chimney Height Requirements:
Vent terminations must be located in accordance
with the height and proximity rules of ANSI Z223.1 / NFPA
54 or CANCGA B149. These rules apply to vents of twelve
inch (12”) diameter and less and require minimum height in
accordance with the roof pitch and a minimum of eight feet (8’)
distance from a vertical wall or other obstruction.
The location selected for the vent termination can
have significant influence on proper draft performance of the
appliance. On a windy day, obstructions such as nearby walls,
trees or topographical features can create high pressure zones.
The vent can become susceptible to windy conditions and tend
to back draft when it is located in such high pressure zones.
In situations where the vent must be installed in a
location that is less than eight feet (8’) from a wall, parapet or
other obstruction, the vent cap must be located at least two feet
(2’) above the obstruction.
For roofs from flat to 7/12 pitch the vent cap must be
positioned at least one foot (1’) above the roof surface.
As the roof pitch increases above 7/12 the roof begins
to act much as a wall with high pressure zones being created
by wind striking the roof itself. To compensate for this it is
necessary to increase the termination height of the vent. The
steeper the roof pitch the greater the vent height needed to
overcome the high pressure zone. See chart below for minimum
height requirements.

IBVs are designed to be installed so that the rough front face of the Isokern firebox and smoke dome sit flush to the room face of
the rough framing members that create the room wall finish.
Important: Do not build a combustible frame wall in front of the IBV firebox / smoke dome assembly. (Figure 25)
Wall Framing for the room wall where the IBV is set must not be placed across the front face of the IBV firebox and smoke dome
assembly.
Clearance to Drywall: Drywall can be placed directly in contact with the front of the IBV firebox and smoke dome. (Figure 24)
With the Isokern firebox/smoke dome set flush with the interior face of wall framing, drywall can be hung on the framing members
and pass across the face of the IBV smoke dome and in contact with it. If necessary, the drywall can be affixed to the face of the
Isokern smoke dome with drywall screws, maximum length one inch (1”) - do not use nails.
The drywall must be cut back a minimum of two inches (2”) from the sides of the firebox opening and eight inches (8”)
back from the top of the IBV firebox opening, leaving IBV material exposed around the face of the IBV firebox opening. These
drywall cut back areas will be filled with grout in conjunction with the installation of the required fire brick lining requirements.

eight inches (8”) away from each side of the finished fireplace opening and a minimum of eight inches (8”) inches above the top
of the finished fireplace opening. (Figure 26 & 27)
Do not attempt to build a combustible framed wall in front of the IBV unit.
If combustible wood sheathing is installed across the face of the Isokern smoke dome front be sure that when the required
noncombustible finished facing materials are applied directly to the front of the IBV, that no gaps or voids are left behind the
finished facing materials. Completely seal the required noncombustible finished facing materials directly to the Isokern unit with
Earthcore Mortar or other noncombustible grout.

Recommended Fire Brick Detail: With drywall crossing over the face of the IBV smoke dome assembly (as previously described
on page 22), to cover the exposed drywall thickness as well as to aid in the overall fit and finish of the IBV front, it is recommended,
when installing the required fire brick lining to the interior of the firebox, that the leading edge of the fire brick - at the floor and
at the side walls of the firebox - project into the room so that the fire brick is finished flush with the room’s finished drywall
surface.
This method of fire brick application, as shown above (Figure 28), allows the fire brick lining to cover the thickness of the drywall
room finish. Also, with fire brick set in this fashion the code required noncombustible finish facing material (see page 28) can be
set tight against the fire brick at the sides of the fireplace opening and at the same time lay flat against the finished wall surface.

Important: Since there is no fire brick set along the top of the IBV firebox opening, when setting the noncombustible facing
material (code required and supplied by others) onto the drywall across the top of the firebox opening there will be a gap between
the back of the noncombustible finish material and the rough front face of the Isokern Smoke Dome (Figure 29).
Be sure to fill this gap with Earthcore Mortar (or similar noncombustible grout) in conjunction with placement of the code
required noncombustible finish facing material that is set across the top of the firebox opening.
WARNING: Avoid false chimneys.
Important: Failure to seal any gaps between the front face of the IBV and the back of the noncombustible finished facing
material will create what is known as a “false chimney” or “secondary chimney”. A “false chimney”, in this case is the narrow gap
(mentioned above) between the back of the noncombustible facing material at the top of the firebox opening and the rough front
of the IBV smoke dome. If left unfilled this gap creates a “false chimney” which can cause a fire hazard by drawing considerable
heat out of the firebox and into the space behind the noncombustible finish facing and from there up into the wall cavity behind
the drywall or other sheathing material that houses the Isokern fireplace.

Interior Full Masonry Veneer Finished Fireplace Front Details
Brick, stone or other full masonry veneer finished
fronts to IBVs are possible. Special attention is required with
regards to: (1) the placement of the proposed masonry veneer
facing and its interface with the IBV fire brick lining, and (2)
the masonry veneer and clearance to combustible framing
and sheathing from any and all steel “L” supports used in the
masonry veneer around the front of the IBV, behind the veneer
facing.
Any proposed brick, stone or other full masonry
veneer facing must have sufficient foundation to support the
full weight of the veneer. Check with local structural engineer
for review of loads prior to construction.
The veneer facing, when installed, must present a tight
seal with the leading edge - the room face edge - of the IBV fire
brick lining at the sides of IBV firebox opening.
A steel “L” (maximum four inch (4”) x six inch (6”))
will need to span the top of the finished fireplace opening to
carry the full masonry veneer over the IBV firebox opening.
(Figure 32 & 33)
This steel “L” should have about four inch (4”) end
bearing. This bearing surface shall be provided in the veneer
work. (Figure 32)
I
t is important that the steel “L” is set in a mud joint,
tight against the Isokern smoke dome front to avoid creating a
“false chimney” between the back of the steel “L” and the front
face of the smoke dome. (Figure 33)

ISO-FLAMES Gas Log Burner Installation
The gas control valve is installed on the right side of the ISOFLAMES gas log burner. If the gas supply line comes into the left side
of the fireplace, the gas supply line must continue to the right side of the fireplace (as close to the rear fire box wall as possible) and
terminate behind the gas valve inlet using rigid 1/2” black iron pipe. At this point only the 3/8” aluminum manifold can be used to
complete the connection to the gas control valve. It may be necessary to cut and reflare the aluminum manifold to the desired length
for proper positioning of the burner pan.
Step 1. Remove all ashes and debris from fireplace.
Step 2. Be sure gas control valve to fireplace is in the OFF position.
Step 3. Place the ISOFLAMES gas log burner in fireplace with grate spokes toward front of fireplace and vertical baffle should be in
line with chimney.
NATURAL GAS OR LIQUID PROPANE
A. Apply pipe thread sealer to gas supply line coming into fireplace and install 3/8” x 1/2” brass supply fitting; tighten.
B. Install longer end of flared aluminum manifold with 3/8” brass flair nut to 3/8” x 1/2” brass supply fitting connected to
gas supply line coming into fireplace, and shorter end to rear of gas control valve; tighten.
C. When connections are complete, NEVER TEST FOR GAS LEAKS WITH A LIT MATCH OR FLAME. Slowly turn gas
control valve to the ON position and use 50/50 soap and water solution with a toothbrush or small paint brush over all gas connections.
A leak will be evident by observation of bubbles on gas connections. If bubbles are observed, retighten leaking gas connectors.
Gas Log Installation:
See pages 36 & 37. Logs are reversible for either a classic bark look, or a rugged split look.

ISOFLAMES Gas Log Assembly Instructions
Isokern Log Placement Instructions
This instruction contains suggested log placement for the ISO-FLAMES log set. Some flexibility is possible in log
placement to suit your individual preference provided excessive sooting does not result from flames striking
the logs too directly (see important below).The suggested log placement will allow for superior flame pattern
and appearance. Please read these instructions completely and carefully before beginning.
Important:
Although there is some flexibility with
the log placement, adequate spacing
between the logs is NECESSARY
and MUST be maintained for best
performance. Some carbon build
up (sooting) may occur where the
flames strike the logs, and should
not be a concern, unless excessive.
If sooting is excessive, rearrange
the top logs to allow more opening
for the flame.
WARNING: Use only parts specifically approved for
use with this gas log set. Failure to do
so may result in property damage or
personal injury. Check with your local
dealer if you need more information.
CAUTION:
35
Burn hazard! Logs will remain hot
for some time after use. If you need
to reposition any log to maintain the
proper layout, use heat resistant
gloves or allow logs adequate time
to cool before handling.
