HHT warrants to the original owner of the HHT appliance at the site of installation, and to any transferee taking ownership
of the appliance at the site of installation within two years following the date of original purchase, that the HHT appliance
will be free from defects in materials and workmanship at the time of manufacture. After installation, if covered compo-
nents manufactured by HHT are found to be defective in materials or workmanship during the applicable warranty period,
HHT will, at its option, repair or replace the covered components. HHT, at its own discretion, may fully discharge all of its
obligations under such warranties by replacing the product itself or refunding the verified purchase price of the product
itself. The maximum amount recoverable under this warranty is limited to the purchase price of the product. This warranty
is subject to conditions, exclusions and limitations as described below.
WARRANTY PERIOD:
Warranty coverage begins on the date of original purchase. In the case of new home construction, warranty coverage
begins on the date of first occupancy of the dwelling or six months after the sale of the product by an independent,
authorized HHT dealer/ distributor, whichever occurs earlier. The warranty shall commence no later than 24 months
following the date of product shipment from HHT, regardless of the installation or occupancy date. The warranty period for
parts and labor for covered components is produced in the following table.
The term “Limited Lifetime” in the table below is defined as: 20 years from the beginning date of warranty coverage for

deteriorate over time and will need occasional replacement.
Seasoned firewood is wood that is cut to size, split and air
dried to a moisture content of around 20%.
WARNING! Risk of Fire! Use only the factory-supplied
integral grate.
Imagine a wooden bucket that weighs about eight pounds.
Fill it with a gallon of water, put it in the fireplace and try to
burn it. This sounds ridiculous but that is exactly what you
are doing if you burn unseasoned wood.
•
•
Keeps logs in place.
Allows proper air circulation around the fire.
E. Firescreen
The firescreen is provided to control sparks. Keep it closed
when the fireplace is in use.
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.
WARNING! Risk of Fire or Burns!
•
Please refer to Section 2.M. for more detail.
Screen will not prevent burning materials from falling
out.
C. Starting a Fire
•
Screen pulls or handles may be hot.
NOTICE: You must establish a good draft to prevent smoke
spillage into the room.
F. Flue Damper
•
•
Refer to Figure 2.1 for location of control.
WARNING! Risk of Fire! Keep combustible materials,
gasoline and other flammable vapors and liquids clear of
the fireplace.
Must be in fully open position (handle up toward the top
of the fireplace) during operation of the fireplace.
Before lighting the fireplace, verify fully open position by
looking up from the inside of the fireplace.
•
DO NOT:
• store flammable materials close to the fireplace
• use gasoline, lantern fuel, kerosene, charcoal lighter
fluid or similar liquids to start or “freshen up” a fire in
this fireplace.
WARNING! Risk of Fire and Asphyxiation! Open damper
prior to operating fireplace. A closed damper overfires
the fireplace and will cause smoke and flames to spill
into the room.
Keep all flammable liquids well away from the fireplace while
it is in use. Combustible materials may ignite.
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 fireplace.
Before lighting the fireplace, turn both handles & pull out
to open. Reverse steps to close and lock.
•
The first three or four fires should be of moderate size to
allow the oils and binders to be burned from the fireplace
and the molded brick panels, and paint to cure. You
may notice an industrial odor the first few fires. This is
considered normal.
•
•
•
•
Use well-seasoned wood (see Section 2.M.).
Open the flue damper to a fully open position.
Place crumpled or twisted paper under the fireplace
grate.
Loosely arrange kindling or small pieces of wood to form
a ‘tent’ on the fireplace grate.
Pre-warm the flue to establish a draft to help reduce smoke
spillage during start-up. Hold a rolled up piece of burning
newspaper under the flue 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.
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 fireplace
(See Molded Brick Panel Maintenance, Section 3.C.)
•
•
•
Add a minimum of three average size pieces of split
firewood, placed to allow combustion air and flames
between them.

Seasoned Wood
M.Wood Fuel
•
•
•
Cut logs to size
Split to 6 in. (152 mm) or less
Air dry to a moisture content of around 20%
Hardwood vs Softwood
Your fireplace performance depends on the quality of the
firewood you use.
-
-
Soft wood - about nine months
Hard wood - about eighteen months
•
•
•
•
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.
NOTICE: Seasoning time may vary depending on drying
conditions.
•
•
•
Soft woods require less time to dry, burn faster and are
easier to ignite.
Start the fire with soft wood to bring the fireplace up to
operating temperature and to establish draft.
Add hard wood for slow, even heat and longer burn
time.
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.

• Oak
• Maple
• Apple
• Birch

•
Store wood under cover to prevent water absorbtion
from rain or snow. Avoid covering the sides and ends
completely.
WARNING! Fire Risk! DO NOT store wood:
• in front of the fireplace.
Moisture
• in space required for loading or ash removal.
WARNING! Risk of Fire!
•
DO NOT burn wet or green wood.
Processed Solid Fuel Firelogs
•
Wet, unseasoned wood can cause accumulation of
creosote.
Manufactured firelogs may be used with this fireplace.
Hearth & Home Technologies Inc. recommends the use of
UL Classified processed fuel firelogs. Follow the manufac-
turer’s lighting and safety instructions.
The majority of the problems fireplace owners experience
are caused by trying to burn wet, unseasoned wood.
Using firelogs may require more frequent chimney inspec-
tion and cleaning.
•
Wet, unseasoned wood requires energy to evaporate the
water instead of heating your home, and
Evaporating moisture cools your chimney, accelerating
formation of creosote.
•
Do not poke or stir the logs while they are burning. Use
only firelogs that have been evaluated for the application in
manufactured fireplaces and refer to firelog warnings and
caution markings on packaging prior to use.

B. Chimney Inspection/Cleaning
A. Disposal of Ashes
Frequency: At least twice a year during heating season or
as recommended by a certified chimney sweep
By: Certified chimney sweep
Frequency: When they reach bottom of grate
By: Homeowner
WARNING! Risk of Fire! Ashes could contain hot embers.
WARNING! Risk of Fire! Ignited creosote is extremely
HOT. Prevent creosote buildup.
•
•
Place ashes in a metal container with a tight-fitting lid.
The closed container should be placed on a non-
combustible floor or on the ground, well away from all
combustible materials, pending final disposal.
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 rela-
tively cool chimney flue of a slow-burning fire. As a result,
creosote residue accumulates on the flue lining. When
ignited this creosote makes an extremely hot fire.
•
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.
WARNING! Risk of Fire! A chimney fire can permanently
damage your chimney system and nearby structures.
In the event of a chimney fire, 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 fire.
Remove 4 screws & lift off top.

B. Design and Installation Considerations
D. Negative Pressure
WARNING! Risk of Asphyxiation! Negative pressure can
cause spillage of combustion fumes and soot. Fire must
draft properly for safe operation.
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, fire
officials or authorities having jurisdiction over restrictions,
installation inspection and permits.
Negative pressure results from the imbalance of air avail-
able for the fireplace to operate properly. It can be stron-
gest in lower levels of the house.
Causes include:
Before installing, determine the following:
•
•
•
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
•
•
•
•
•
Where the fireplace is to be installed.
The vent system configuration to be used.
Gas supply piping.
Framing and finishing details.
Whether optional accessories are desired.
•
•
•
•
C. Draft
Draft is the pressure difference needed to vent fireplaces
successfully. When a fireplace is drafting successfully, all
combustion by-products are exiting the home through the
chimney.
- Attic hatch
- Duct leaks
To minimize the effects of negative air pressure:
Considerations for successful draft include:
•
•
•
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 fireplace
Avoid installing the fireplace 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
•
•
Preventing negative pressure
Location of fireplace and chimney
NOTICE: Hearth & Home Technologies assumes no
responsibility for the improper performance of the fireplace
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.
•
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.

E. Locating your Fireplace & Chimney
Location of the fireplace and chimney will affect perfor-
mance.
•
Install within the warm airspace enclosed by the building NOTICE: Locating the fireplace in an area of considerable
envelope. This helps to produce more draft, especially air movement can cause intermittent smoke spillage from
during lighting and die-down of the fire.
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.

E. Cut Roof Opening
A MAJOR CAUSE OF VENT RELATED FIRES IS FAIL-
URE 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.
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 2-inch clearance to combustibles.
B. Clearances
Always allow at least a 2-inch clearance between Dura-
Chimney II Pipe and any combustible materials.
F. Install Firestop
•
Never fill any required clearance space with insulation or
any other materials.
A firestop is required on each floor penetration in multi-
story installation. Building Codes require a firestop at every
floor/ceiling level, including where the chimney penetrates
into the attic. Figure 8.1 shows a typical 2-story installation
with an attic.
•
Combustible materials include lumber, plywood, sheetrock,
plaster and lath, furniture, curtains, electrical wiring, and
building insulation.
Note: a firestop is not installed where the chimney pen-
etrates through the roof.
C. Installation Notes
•
The firestop is installed on the underside of the ceiling/floor
framing (Figure 8.2).
Use a minimum of one 8 penny nail or one 1-1/4” wood
screw per corner.
Proper planning for your DuraChimney II installation will
result in greater safety, efficiency, 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.
•
Framing
•
•
Do not install damaged or modified 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 modifications to roof beams and other structural
components of the building.
If you have any questions, contact either your dealer or
Simpson Dura-Vent directly.
D. Frame Openings
•
From the ceiling, drop a plumb bob to the center of the
fireplace’s flue outlet and mark this center point on the
ceiling.
Figure 8.2
•
Mark appropriate cutting lines around the center point.
Cut a square hole in the ceiling. Frame a level, square,
21 in. x 21 in. (533 mm x 533 mm) opening centered over
the hole that you have cut.
•
Frame openings at each floor level above the fireplace
(Figure 8.1). 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 specified in
Table 8.1.

G. Assemble Chimney Sections
H. Using Offsets/Returns
•
Attach the first chimney section or offset onto
the top of the fireplace (Figure 8.3). Sheet metal
screws are required to connect chimney section
to the fireplace starter collar. Continue to add
additional sections of chimney as needed.
Use a wall strap every eight feet of chimney
height.
For each additional chimney section use four
of the sheet metal screws provided to make a
secure connection between the chimney sections
(Figure 8.4). Do not penetrate the inner liner of
the chimney.
•
•
Use an offset/return to bypass overhead obstructions.
An offset and return can be used as a single entity or
separated by chimney section(s).
WARNING! Rish of Fire! DO NOT use offset/returns great-
er than 30’. Chimney draft will be restricted and could cause
overheating and fire.
•
•
•
Measure the shift required to avoid the overhead
obstruction (Offset, Figure 8.5).
•
•
Find the appropriate offset dimension listed in Table 8.2.
The rise (see Figure 8.5) coinciding with the offset
dimension measurement in Table 8.2 represents the
required vertical clearance needed to complete the offset/
return.

I. Offset Elbow Installation
J. Supplementary Support & Stabilizer
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 efficient. When Elbows are necessary to avoid
obstructions such as rafters, ridgepoles, or joists, you are
only allowed to use 2 pair of Elbows in any one chimney
system. Horizontal runs of chimney violate building code
and are not allowed.
Install a supplementary support if total chimney height is
greater than 50-feet, or if the fireplace manufacturer re-
quires it. If additional support is needed, install one or more
supplementary supports which can each support 25-feet of
chimney (Fig. 8.8).
•
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.Astabilizer is available and may be required
by some fireplace manufacturers to keep the chimney
vertical and help maintain clearances to combustibles
within a chase.
•
Attach elbows
Attach elbow to chimney section or other elbow by ating the
male and female ends with each other and using four 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

•
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 firm. Wrap the elbow strap end over an adjacent joist
or rafter and secure it with at least two 8-penny nails or
two #8, 1-1/2” screws. Add additional elbow straps for
each section of chimney in the offset (Figure 8.7). 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.

K. Install Attic Insulation Shield
L. Install Roof Radiation Shields
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 fit, 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:
Roof radiation shields must be used to provide protection
for roof or chase 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.
•
Install roof radiation shields at either the top of the chase
or where the chimney penetrates the roof, whichever is
the top of the installation.
•
•
•
•
Remove any insulation from attic floor 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 8.10).
Secure the attic insulation shield to the top of the framed
opening using at least two 8-penny nails ort wo #8,
1-1/2 in. wood screws per side (Figure 8.11).
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 8.11).
•
Roof radiation shields are built with a 1/2” air gap standoff
from the joist face (Figure 8.12). The corners of the roof
radiation shields overlap each other to ensure proper
position.
•
•
Secure the roof radiation shields to the top of the framing
members using screws or nails in the corners.
If framing members are further away from the chimney
than 2 in., center the roof radiation shield to the chimney
on the framing member and secure in place with screws
or nails.

Chase Installations
9
Gas line holes and other openings should be caulked with
high temperature caulk or stuffed with unfaced fiberglass
insulation. If the fireplace 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.
A. Construct the Chase
A chase is a vertical boxlike structure built to enclose the
fireplace 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 build-
ing. These instructions are not substitutes for the require-
ments of local building codes. Local building codes MUST
be checked.
Three examples of chase applications are shown in Fig-
ure 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.
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.
Note: In cooler climates, all chase walls should be insulated.
Building codes require false ceiling and ceiling firestops
at each floor of the chase or every 10 ft (3.05 m) of clear
space to control spread of fire.
Walls, ceiling, base plate and cantilever floor at the first
level of the chase should be insulated. See Figure 9.1.
Vapor and air infiltration barriers should be installed in the
chase as per regional codes for the rest of the home. Addi-
tionally, Hearth & Home Technologies recommends that the
inside surfaces be sheet rocked and taped (or the use of an
equivalent method) for maximum air tightness.

G. Install Mortar (Optional)
Inside
Firebox
The brick panels have been designed for installation
without the use of mortar being necessary. If the
look of mortar is preferred, it is vaailable and can be
installed. Follow the directions on the container for
mixing.
H. Grate
The mortar can be applied with a mortar bag or
trowled on. Applying with mortar bag may be easiest
and less messy. Clean sparingly as paint will rub off
and may need to be touched up. Touch up paint is
abailable as an accessory.
•
•
•
Install the grate if a gas log set is not going to be installed.
Position the rear grate bar in the Grate Retainer.
Position the top of the grate retainer over the rear grate
bar and fasten in place with screw provided.
VERY IMPORTANT: Allow the mortar 72 hours to cure before operating the fireplace.
The noncombustible finishing
material across the top of
fireplace opening will be even
with lower edge of metal face.
If Mortar is applied, it should be applied after
finishing material is installed. Mortar will be
applied between finishing materials and
molded brick edges, bottom and sides.
Noncombustible finishing
materials MUST overlap
side faces by 1 1/4 in. (32 mm)
to cover the edges of the
panels. Finished opening
should be 36 x 38 in. (914 x
965 mm) to allow for door
installation.
The seam between finishing materials and
firebox top must be sealed with non-
combustible sealant.
The surface of the finished hearth extension and
the surface of the hearth panel should be level.
