WARNING
HOT SURFACES!
Screen/mesh, glass doors and other surfaces are hot during operation AND cool down.
Hot screen/mesh and glass doors will cause burns.
• DO NOT touch screen/mesh or glass doors until cooled
• NEVER allow children to touch screen/mesh or glass doors
• Keep children away
• CAREFULLY SUPERVISE children in same room as fi replace.
• Alert children and adults to hazards of high temperatures.
High temperatures may ignite clothing or other fl ammable materials.
• Keep clothing, furniture, draperies and other fl ammable materials away.
If you expect that children may come into contact with this fi replace, we recommend a barrier such as a decorative

B. Seasoned Wood
Properly seasoned wood is important for successful operation of your fi replace. Most woodburning fi replace problems
are caused by burning wet, unseasoned wood.
Seasoned fi rewood is wood that is cut to size, split and air
dried to a moisture content of around 20%.
Imagine a wooden bucket that weighs about eight pounds.
Fill it with a gallon of water, put it in the fi replace and try to
burn it. This sounds ridiculous but that is exactly what you
are doing if you burn unseasoned wood.
A tree cut down a year ago and not split is likely to have
almost as high a moisture content now as it did when it was
cut.
Please refer to Section 2.M. for more detail.
C. Starting a Fire
NOTICE: You must establish a good draft to prevent smoke
spillage into the room.
WARNING! Risk of Fire! Keep combustible materials,
gasoline and other fl ammable vapors and liquids clear of
the fi replace.
DO NOT:
• store fl ammable materials close to the fi replace
• use gasoline, lantern fuel, kerosene, charcoal lighter
fl uid or similar liquids to start or “freshen up” a fi re in
this fi replace.
Keep all fl ammable liquids well away from the fi replace while
it is in use. Combustible materials may ignite.
• The fi rst three or four fi res should be of moderate size to
allow the oils and binders to be burned from the fi replace
and the molded brick panel, and paint to cure. You
may notice an industrial odor the fi rst few fi res. This is
considered normal.
• Use well-seasoned wood (see Section 2.M.).
• Open the fl ue damper to a fully open position.
• Place crumpled or twisted paper under the fi replace
grate.
• Loosely arrange kindling or small pieces of wood to form
a ‘tent’ on the fi replace grate.
• Pre-warm the fl ue to establish a draft to help reduce smoke
spillage during start-up. Hold a rolled up piece of burning
newspaper under the fl ue damper for a few moments.
• Light the crumpled paper to ignite the kindling.
• Add small pieces of wood until a hot bed of embers has
been established.
• Add a minimum of three average size pieces of split
fi rewood, placed to allow combustion air and fl ames
between them.
D. Grate
This fi replace is designed to be used with the grate sup-
plied with this unit or one approved by HHT. The grate will
deteriorate over time and will need occasional replacement.
WARNING! Risk of Fire!
integral grate.
• Keeps logs in place.
• Allows proper air circulation around the fi re.
Use only the factory-supplied
E. Firescreen
The fi rescreen is provided to control sparks. Keep it closed
when the fi replace is in use.
WARNING! Risk of Fire or Burns!
• Screen will not prevent burning materials from falling
out.
• Screen pulls or handles may be hot.
F. Flue Damper
• Refer to Figure 2.1 for location of control.
• Must be in fully open position (handle up toward the top
of the fi replace) during operation of the fi replace.
• Before lighting the fi replace, verify fully open position by
looking up from the inside of the fi replace.
WARNING! Risk of Fire and Asphyxiation! Open damper
prior to operating fi replace. A closed damper overfi res
the fi replace and will cause smoke and fl ames to spill
into the room.
G. Outside Air
• Refer to Figure 2.1 for location of controls.
• Outside air doors should be in the fully opened position
during operation of the fi replace.
• Before lighting the fi replace, turn both handles & pull out
to open. Reverse steps to close and lock.
H. Molded Brick Panel
• The molded brick panel is shipped separately, but required
to contain heat and provide an attractive interior.
• It will deteriorate over time and will need occasional
replacement. Small hairline cracks and discoloration are
normal and do not affect its safety.
• Cracks in the mortar may occur and do not affect the
safety of the unit. If mortar falls out of the joints and metal
is exposed, replace or patch the mortar.
• (See Molded Brick Panel Maintenance, Section 3.C.)
WARNING! Risk of Fire! DO NOT burn fi replace without
molded brick panel. Use only molded brick panel supplied
by Hearth & Home Technologies, Inc.
CAUTION! Odors and vapors released during initial operation may be irritating to sensitive individuals. Open windows
for air circulation.

M. Wood Fuel
Hardwood vs Softwood
Your fi replace performance depends on the quality of the
fi rewood you use.
• Seasoned wood contains about 8,000 BTUs per pound .
• Hard woods are more dense than soft woods.
• Hard woods contain 60% more BTUs than soft woods.
• Hard woods require more time to season, burn slower and
are harder to ignite.
• Soft woods require less time to dry, burn faster and are
easier to ignite.
• Start the fi re with soft wood to bring the fi replace up to
operating temperature and to establish draft.
• Add hard wood for slow, even heat and longer burn
time.
Soft woods Hard woods
• Douglas Fir • Oak
• Pine • Maple
• Spruce • Apple
• Cedar • Birch
• Poplar
• Aspen
• Alder
Seasoned Wood
• Cut logs to size
• Split to 6 in. (152 mm) or less
• Air dry to a moisture content of around 20%
- Soft wood - about nine months
- Hard wood - about eighteen months
NOTICE: Seasoning time may vary depending on drying
conditions.
Storing Wood
Steps to ensure properly seasoned wood:
• Stack wood to allow air to circulate freely around and
through woodpile.
• Elevate wood pile off ground to allow air circulation
underneath.
• Smaller pieces of wood dry faster. Any piece over 6 in.
(152 mm) in diameter should be split.
• Wood (whole or split) should be stacked so both ends of
each peice are exposed to air. More drying occurs through
the cut ends than the sides.
• Store wood under cover to prevent water absorbtion
from rain or snow. Avoid covering the sides and ends
completely.
Moisture
WARNING! Risk of Fire!
• DO NOT burn wet or green wood.
• Wet, unseasoned wood can cause accumulation of
creosote.
The majority of the problems fi replace owners experience
are caused by trying to burn wet, unseasoned wood.
• Wet, unseasoned wood requires energy to evaporate the
water instead of heating your home, and
• Evaporating moisture cools your chimney, accelerating
formation of creosote.
WARNING! Fire Risk! DO NOT store wood:
• in front of the fi replace.
• in space required for loading or ash removal.
Processed Solid Fuel Firelogs
Manufactured fi relogs may be used with this fi replace.
Hearth & Home Technologies Inc. recommends the use of
UL Classifi ed processed fuel fi relogs. Follow the manufac-
turer’s lighting and safety instructions.
Using fi relogs may require more frequent chimney inspec-
tion and cleaning.
Do not poke or stir the logs while they are burning. Use
only fi relogs that have been evaluated for the application in
manufactured fi replaces and refer to fi relog warnings and
caution markings on packaging prior to use.

A. Disposal of Ashes
Frequency: When they reach bottom of grate
By: Homeowner
WARNING! Risk of Fire! Ashes could contain hot embers.
• Place ashes in a metal container with a tight-fi tting lid.
• The closed container should be placed on a noncombustible
fl oor or on the ground, well away from all combustible
materials, pending fi 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.
B. Chimney Inspection/Cleaning
Frequency: At least twice a year during heating season or
as recommended by a certifi ed chimney sweep
By: Certifi ed chimney sweep
WARNING! Risk of Fire! Ignited creosote is extremely
HOT. Prevent creosote buildup.
Refer to Figure 3.1 to remove/reinstall termination caps.
Creosote - Formation and 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 fl ue of a slow-burning fi re. As a result,
creosote residue accumulates on the fl ue lining. When
ignited this creosote makes an extremely hot fi re.
WARNING! Risk of Fire! A chimney fi re can permanently
damage your chimney system and nearby structures.
In the event of a chimney fi re, Hearth & Home Technolo-
gies Inc. recommends
• replacement of the chimney, and
• inspection of the adjacent structure to the provisions of
NFPA Level III inspection criteria
The chimney shall be inspected at least twice a year during
the heating season to determine when a creosote buildup
has occurred.
When creosote has accumulated it shall be removed to
reduce the risk of a chimney fi re.

B. Design and Installation Considerations
D. Negative Pressure
NOTICE: Check building codes prior to installation.
• Installation MUST comply with local, regional, state and
national codes and regulations.
• Consult insurance carrier, local building inspector, fi re
offi cials or authorities having jurisdiction over restrictions,
installation inspection and permits.
Before installing, determine the following:
• Where the fi replace is to be installed.
• The vent system confi guration to be used.
• Gas supply piping.
• Framing and fi nishing details.
• Whether optional accessories are desired.
C. Draft
Draft is the pressure difference needed to vent fi replaces
successfully. When a fi replace is drafting successfully, all
combustion by-products are exiting the home through the
chimney.
Considerations for successful draft include:
• Preventing negative pressure
• Location of fi replace and chimney
NOTICE: Hearth & Home Technologies assumes no
responsibility for the improper performance of the fi replace
system caused by:
• Inadequate draft due to environmental conditions
• Downdrafts
• Tight sealing construction of the structure
• Mechanical exhausting devices
• Improper positioning of the chimney in a not-recommended
location on the roof.
WARNING! Risk of Asphyxiation! Negative pressure can
cause spillage of combustion fumes and soot. Fire must
draft properly for safe operation.
Negative pressure results from the imbalance of air available for the fi replace to operate properly. It can be stron-
gest in lower levels of the house.
Causes include:
• Exhaust fans (kitchen, bath, etc.)
• Range hoods
• Combustion air requirements for furnaces, water heaters
and other combustion appliances
• Clothes dryers
• Location of return-air vents to furnace or air conditioning
• Imbalances of the HVAC air handling system
• Upper level air leaks such as:
- Recessed lighting
- Attic hatch
- Duct leaks
To minimize the effects of negative air pressure:
• Ensure adequate outdoor air for all combustion appliances
and exhaust equipment
• Ensure furnace and air conditioning return vents are not
located in the immediate vicinity of the fi replace
• Avoid installing the fi replace near doors, walkways or small
isolated spaces
• Recessed lighting should be a “sealed can” design
• Attic hatches weather stripped or sealed
• Attic mounted duct work and air handler joints and seams
taped or sealed
• Basement installations should be avoided
NOTICE: The fireplace provides some outside air for
combustion. Other methods may be necessary if more air
is required.
NOTICE: Hearth & Home Technologies Inc. recommends the
use of direct vent appliances in basements.

mance.
• Install within the warm airspace enclosed by the building
envelope. This helps to produce more draft, especially
during lighting and die-down of the fi re.
• Penetrate the highest part of the roof. This minimizes the
effects of wind loading.
• Locate termination cap away from trees, adjacent
structures, uneven roof lines and other obstructions.
• Minimize the use of chimney offsets.
• Consider the fi replace location relative to fl oor and ceiling
and attic joists.
• Take into consideration the termination requirements in
Section 8 and Section 9.

Determine the chimney components needed to complete
your particular installation:
• Measure the total vertical height of the fi replace installation
from the base of the fi replace assembly to the approximate
location of the bottom of the termination cap.
• Subtract the effective height of the fi replace assembly (see
Figure 8.2) from the total vertical height to determine the
overall height of the chimney installation.
• Create a schematic for your application similar to Figure
8.2 showing components required (referring to Table 8.1).
Figure 8.1 identifi es those components and where used.
• Install a ceiling fi restop whenever the chimney penetrates
a fl oor/ceiling.
NOTICE: A maximum of one offset and return may be
used.
WARNING! Risk of Fire!
You must maintain 2 in. (51 mm)

A MAJOR CAUSE OF VENT RELATED FIRES IS FAILURE TO MAINTAIN REQUIRED CLEARANCES (AIR
SPACES) TO COMBUSTIBLE MATERIALS. IT IS OF
THE UTMOST IMPORTANCE THAT DURACHIMNEY II
BE INSTALLED ONLY IN ACCORDANCE WITH THESE
INSTRUCTIONS.
B. Clearances
Always allow at least a 2-inch clearance between DuraChimney II Pipe and any combustible materials. Never fi ll
any required clearance space with insulation or any other
materials. Combustible materials include lumber, plywood,
sheetrock, plaster and lath, furniture, curtains, electrical
wiring, and building insulation.
C. Installation Notes
Proper planning for your DuraChimney II installation will
result in greater safety, effi ciency, and convenience, as well
as saving time and money. You must use only authorized
DuraChimney II parts to maintain a listed chimney system.
Do not mix parts or try to match with other products or use
improvised solutions. Do not install damaged or modifi ed parts. Practice good workmanship. Sloppy work could
jeopardize your chimney’s safety. Keep electrical wiring
and building insulation away from all chimneys. When
deciding the location of your chimney, try to avoid modifi -
cations to roof beams and other structural components of
the building. If you have any questions, contact either your
dealer or Simpson Dura-Vent directly.
E. Cut Roof Opening
Determine and cut an opening in the roof directly above
the opening below, and at least 4-inches larger than the
chimney’s outside diameter to provide at least a 2-inch
clearance all around the chimney. The chimney must be
centered within this opening and maintain the minimum 2inch clearance to combustibles.
F. Install Firestop
A Firestop is required on each fl oor penetration in multisto-
ry installation. Building Codes require a Firestop at every
fl oor/ceiling level, including where the chimney penetrates
into the attic. Figure 8.2 shows a typical 2-story installation
with an attic. Note: a Firestop is not installed where the
chimney penetrates through the roof. The Firestop is installed on the underside of the ceiling/fl oor framing (Figure
8.3). Use a minimum of either (1) 8 penny nail or (1) 1-1/4”
wood screws per corner.
Framing
D. Frame Openings
From the ceiling, drop a plumb bob to the center of the
fi replace’s fl ue outlet and mark this center point on the ceil-
ing. Mark appropriate cutting lines around the center point.
Cut a square hole in the ceiling. Frame a level, square
opening centered over the hole that you have cut. Frame
openings at each fl oor level above the Fireplace (Figure
8.2). These openings are to hold the Firestop and Attic
Insulation shield. Locate each opening by dropping a plumb
bob to the four corners of the opening below. Maintain the
minimum 2-inch clearance/air space. Maintain the minimum
clearances and dimensions as specifi ed in Table 8.1.

G. Assemble Chimney Sections
Attach the fi rst chimney section or offset onto the top of the
fi replace (Figure 8.4). Sheet metal screws are required to
connect Chimney Section to Anchor Plate. Continue to add
additional sections of chimney as needed. Use a Wall Strap
every eight (8) feet of chimney height. For each additional
Chimney Section use (4) sheet metal screws provided, to
make a secure connection between the chimney sections
(Figure 8.5). Do not penetrate the inner liner of the chimney.
H. Supplementary Support and Stabilizer
If additional support is needed, install one or more Supplementary Supports which can each support 25-feet of
chimney (Figure 8.6). Clamp the Supplementary Support
band around the pipe using the nut and bolt provided, and
anchor the support to nearby building framing. Always
maintain the 2” clearance to combustibles from the chimney pipe. A Stabilizer is available and may be required by
some fi replace manufacturers to keep the chimney verti-
cal and help maintain clearances to combustibles within a
chase. Clamp the Stabilizer to the pipe using the nut and
bolt provided, and secure lets to nearby framing using the
plumber’s tape or guy-wires ( Figure 8.7). Note: the Stabilizer does not support the weight of the chimney, it is only
used to keep chimney centered within a chase.

I. Install Attic Insulation Shield
The Attic Insulation Shield must be installed where the
chimney passes into an attic. Its purpose is to prevent
debris and insulation from getting too close to the chimney.
In attic areas where this shield cannot fi t, or is not used you
must enclose the attic portion of the chimney in a framed
enclosure. If the chimney is fully enclosed through the attic,
an Attic Insulation Shield is not required. Install the Attic
Insulation Shield as follows:
• Remove any insulation from attic fl oor around the framed
opening.
• Assemble Chimney Sections until at least 18 inches of
chimney extends above the Firestop.
• Slip the Attic Insulation Shield over the chimney until the
base sits squarely on the framed opening (Figure 8.8).
• Secure the Attic Insulation Shield to the top of the framed
opening using at least (2) 8-penny nails or (2) #8, 1-1/2
in. wood screws per side (Figure 8.9).
• Wrap the Collar of the Attic Insulation Shield around the
chimney and fasten it loosely. Slide the Collar down to
meet the Attic Insulation Shield. Tighten the bolts to secure
the Collar in place (Figure 8.9).
J. Install Roof Radiation Shields
Roof Radiation Shields provide protection for roof framing
members. Note: Roof Radiation Shields do not allow for
a reduced clearance to combustibles. Clearance to combustibles must be a minimum of 2” away from the chimney
pipe. When you penetrate through the roof, Roof Radiation
Shields must be installed with a 1/2” air gap between the
shields and the joist face (Figure 8.10). Depending on the
pitch of your roof, trim the Roof Radiation Shields with tin
snips so they provide coverage of the roof framing exposed to the chimney. Secure the Roof Radiation Shields
to the top of the framing members using at least (3) nails or
screws for each shield (Figure 8.10).

K. Finish Top
Apply a non-hardening waterproof sealant around the
chimney at the point where the Storm Collar will meet the
chimney just above the fl ashing (Figure 8.14). Slide the
Storm Collar down over the chimney to the top of the fl ash-
ing. The Storm Collar must be installed 1” off the Chase
Top Flashing to provide proper ventilation (Figure 8.14).
Tighten the bolts of the Storm Collar and seal the Storm
Collar against the Chimney with sealant. Be sure Chimney
and Offsets are properly supported. Attach the Chimney
Cap onto the top of the chimney by setting the female end
of the Cap onto the male end of the last Chimney Section.
Secure the Cap by using (4) sheet metal screws provided
Figure 8.15.) Do not push down from the top portion of the
cap as this may damage the cap. Push from the lower section of the Cap if needed. The Chimney Cap can removed
for chimney cleaning as described in the Chimney Maintenance section of this manual.
L. Enclosures
Enclose chimneys where they pass through occupied
spaces, including closets. Always maintain at least a 2-inch
clearance between the chimney and any combustible materials. Interior enclosures may be constructed with standard
framing and sheathed with sheetrock or plywood. Use a
Wall Strap or Stabilizer at least every 8 feet to maintain a
minimum of 2 inches of air space between the chimney and
combustible materials.
Sealant
Collar
M. Offset Elbow Installation
A 30° Elbow (measured from the vertical) is the largest that
can be used in an offset. A 30° Elbow may not be combined
with another Elbow to make a steeper offset (e.g. two 30°
Elbows are not allowed to be put together to form a 60°
elbow.). Avoid Elbows if possible. A totally vertical chimney
is more effi cient. When Elbows are necessary to avoid
obstructions such as rafters, ridgepoles, or joists, you are
only allowed to use 1 pair of Elbows in any one chimney
system. Horizontal runs of chimney violate building code
are not allowed.
• Attach Elbows
Attach Elbow to Chimney Section or other Elbow by
mating the male and female ends with each other and
using the (4) sheet metal screws provided. Attach one
Elbow to the Chimney Section below, and align it for the
offset. Determine the required offset length and attach
an appropriate length (or lengths) of Chimney Section(s)
above the Elbow. Attach the second Elbow above the
Chimney Section to complete the offset (Figure 8.16).
• Secure Offset
Use an Elbow Strap to secure the offset. Secure the Elbow
Strap’s band to chimney around the upper portion of the
top Elbow, then tighten the nut and bolt until the clamp
is fi rm. Wrap the Elbow Strap end over an adjacent joist
or rafter and secure it with at least two 8-penny nails or
#8, 1-1/2” screws. Add additional Elbow Straps for each
section of chimney in the offset (Figure 8.17). Every
Chimney Section in the offset must be supported. Do not
add more Chimney Sections until the Elbows and offset are
supported. Be sure that the chimney remains vertical.

Chase Installations
9
A. Construct the Chase
A chase is a vertical boxlike structure built to enclose the
fi replace and/or its vent system. Vertical chimneys that
run on the outside of a building must be installed inside a
chase.
Construction of the chase may vary with the type of building. These instructions are not substitutes for the requirements of local building codes. Local building codes MUST
be checked.
A chase should be constructed in the manner of all outside
walls of the home to prevent cold air drafting problems. The
chase should not break the outside building envelope in
any manner. All outer walls need to be insulated.
Building codes require false ceiling and ceiling fi restops
at each fl oor of the chase or every 10 ft (3.05 m) of clear
space to control spread of fi re.
Walls, ceiling, base plate and cantilever fl oor at the fi rst
level of the chase should be insulated. See Figure 9.1.
Vapor and air infi ltration barriers should be installed in the
chase as per regional codes for the rest of the home. Additionally, Hearth & Home Technologies recommends that the
inside surfaces be sheet rocked and taped (or the use of an
equivalent method) for maximum air tightness.
Gas line holes and other openings should be caulked with
high temperature caulk or stuffed with unfaced fi berglass
insulation. If the fi replace is being installed on a cement
slab, we recommend that in cold climates, a sheet of
plywood or other raised platform be placed underneath to
prevent conducting cold up into the room.
Three examples of chase applications are shown in Figure 9.2.
1. Fireplace and chimney enclosed in an exterior chase.
2. Chimney offset through exterior wall and enclosed in chase.
3. Chase constructed on roof.
Note: In cooler climates, all chase walls should be insulated.

WARNING! Risk of Fire! DO NOT seal area between fi re
stop opening and chimney pipe except where they enter the
attic or leave the warm air envelope of the home (use 600° F
sealant).
WARNING! Risk of Fire! You must maintain a minimum
2 in. (51 mm) air space clearance to insulation and other
materials surrounding the chimney system.
• Insulation and other materials must be fi rmly secured to
prevent accidental contact with chimney system.
• Failure to prevent contact between insulation or other
materials and chimney system may cause overheating
and fi re.

B. Install Fireplace & Chimney
Install as per Sections 7 and 8.
C. Install Chase Top Flashing
• You MUST use a chase top fl ashing in a chase installation.
Chase top fl ashings are available from your Heat & Glo
dealer or may be fi eld constructed.
For chase enclosures, use a chase top fl ashing. The chase
top fl ashing allows for a 1 1/2 in. (38 mm) clearance around
the outside of the chimney pipe for ventilation air. Install the
chase top fl ashing at the top of the chase with a 1/2 in. (13
mm) air clearance off the top of the chase constructions
(Figure 9.4, 9.5). Use spacing clips to ensure the 1/2 in.
(13 mm) air clearance. If the chase top fl ashing does not
fi t the dimensions of the chase, a custom fl ashing can be
fi eld-fabricated as long as it has the same dimensions as
noted in Figure 10.1. Secure the chase top fl ashing to the
chase with at least three screws or nails per side. When
installed, the bottom of the termination cap must be at least
6 in. (152 mm) above the chase top fl ashing (Figure 9.6).

Shrouds
A. Shroud Requirements
WARNING! Risk of Fire! Shrouds must be constructed as
specifi ed. Improper construction may overheat chase top.
• Chase top shrouds may be field constructed where
permitted by regional building codes.
NOTICE: Some regional codes require an agency-Listed
shroud. Consult your local building offi cials.
• Hearth & Home Technologies Inc. supplies UL listed
shrouds. See your dealer for details.
Shrouds can either be fi eld-fabricated or factory-fabricated,
but they must meet the requirements as specifi ed in these
instructions. Shrouds must be constructed of a minimum
24 ga (.024 in.) stainless steel, aluminized steel, galvanized steel, or copper. Other materials may also be used,
such as brick, mortar, stucco, stone, etc. provided they are
completely non-combustible. Check with your local building
code authroities for any additional shroud requirements.
Shrouds must be able to be removed to allow chimney access to properly clean the chimney. DuraChimney II installations which include the use of a shroud must comply with
the following requirements (Figure 10.1)
• DuraChimney II must maintain at least 2 in. (51 mm)
clearance from combustible materials.
• The chase enclosure must be ventilated.
• The chase top fl ashing or fi eld-fabricated chase pan must
be used. Field-fabricated chase pans are acceptable if
they meet these requirements:
- Material must be 24 ga (.024 in) galvanized steel or
equivalent.
- Chase pan must have opening 3 in. (76 mm) larger
than outside diameter of chimney pipe with at least a
1/2 in. (13 mm) upturned fl ange/collar.
- Chase pan must overhang chase by 1/2 in. (13 mm)
per side for proper air fl ow.
- Chase pan must have a 1 in. (25 mm) down turned
outside edge (weather prtection).

F. Install Mortar
Note: We recommend mortar be applied after
facing materials are installed.
Tools Required:
Mortar bag Drill
Trowel 3/32 drill bit (provided)
Mixing bucket Phillips screwdriver
Sponge or spray bottle Joint striker
Drill with mixing attachment (optional)
Bucket of water
NOTICE: Do not stubstitute for HHT mortar. Other materials
may stain the molded brick panels.
The mortar material provided should be suffi cient to com-
plete the installation of the molded brick panels without
considerable waste.
• Mix approximately 1/3 of the mortar material with 1/2
gallon of water in the mixing bucket. Stir the mixture with
the mixing attachment and drill. The consistency should
allow the material to be squeezed from the mortar bag but
not too runny.
• Fill the mortar bag with the prepared mixture.
• Apply mortar by squeezing the material from the mortar
bag into the joint lines. If fi lling a vertical line, start from
the top and work down. Apply slowly. Mixture should be
fl ush or higher than the refractory surface.
• Mix more material as necessary to fi nish the job and then
let the unit set until fi rm, may take two hours or more.
• Thoroughly clean the bag, tools and mixing bucket.
• Use a joint striker and strike the material in the joints. The
excess material should fall off somewhat dry.
• Sweep the loose material off the fl oor of the unit.
• Final cleanup with soap and water
• VERY IMPORTANT: Allow the mortar 72 hours to cure
before operating the fi replace.
Mortar should be applied
after the finishing material
is installed. Mortar will be
applied between the
finishing materials and the
refractory edges, bottom
and sides.
The seam between the
finishing materials and
firebox top must be sealed
