Fire Risk

Provide adequate clearances.

• Around air openings

• To combustibles

• For service access.
Locate fi replace away from traffi c areas.

A. Selecting Fireplace Location

This fi replace is intended for installation on an outdoor patio
or in your yard. It must never be installed inside of the warm
air envelope of your structure. Signifi cant cold air infi ltration
will result if it is installed inside of the structure. Figures 3.1
and 3.2 show typical installations.

When installing the outdoor fi replace against an outside wall,
it must be enclosed to prevent impact damage to the outside
of the fi replace. Build the outside enclosure out of standard
building materials, being careful to maintain the minimum air
clearances specifi ed in these installation instructions.

When installing this fi replace as a freestanding fi replace on
your porch, patio or in your yard, it must be enclosed to pre­vent impact damage to the fi replace. However, the enclo­sure must not be fi nished on all four sides. The exterior of
the enclosure may be fi nished in a textured plywood, a wood
clapboard siding, brick, or a cultured stone. Vinyl siding is
not recommended for use on the front of the fi replace due
to the heat the fi replace produces. This can cause the vinyl
siding to deteriorate.

• Place the Protective Metal Hearth Strips

WARNING

Fire Risk!

• Metal hearth strips MUST be installed.
Sparks or embers may ignite fl ooring.

Included with your fi replace you will fi nd two metal
hearth strips measuring approximately 26 in. x 4 in.
(660 mm x 102 mm). These strips are used to provide
added protection where the fi replace and the hearth ex­tension meet.

Slide each metal strip 2 in. (51 mm) under the front
edge of the fi replace. The individual pieces must over­lap each other by 1 in. (25 mm) minimum in the middle
of the fi replace to provide continuous coverage of the
fl oor. See Figure 4.4. These metal strips should extend
from the front and sides of the fi replace opening by 2 in.
(51 mm).

1 in. (25 mm) overlap

Metal strips are placed 2 in. (51 mm) under the front
of the fireplace and must extend beyond the front
and sides of fireplace opening by 2 in. (51 mm).

• Level the Fireplace

Level the fi replace side-to-side and front-to-back. Shim
with noncombustible material, such as sheet metal, as
necessary. Secure the fi replace (using the nailing fl ang­es located on either side of the fi replace) to the vertical
framing.

Important: To ensure proper fi t of the glass doors, check
the fireplace opening for square. Measure diagonal
distances of the opening to make sure they are equal.
If they are not, continue to shim the fi replace until those
diagonals are equal.

WARNING

To determine the chimney components needed to complete
your particular installation, follow the steps below:

• Determine the total vertical height of the fireplace
installation. This dimension is measured from the base of
the fi replace assembly to the point where the smoke exits
the termination cap.

• Subtract the effective height of the fi replace assembly from
the overall height of the fi replace installation (measured
from the base of the fireplace to the bottom of the
termination cap).

• Refer to Table 5.1 to determine what components must
be selected to complete the fi replace installation.

• Determine the number of ceiling fi restops, stabilizers,
roof flashing, etc. required to complete the fireplace
installation.

CAUTION

• Do NOT connect this fireplace to a chimney flue
servicing another appliance.

• Do NOT connect to any air distribution duct or
system.

Fire Risk

• Must maintain 2 in. (51 mm) air clearance
to insulation and other combustible
materials.

B. Using Offsets/Returns

To bypass any overhead obstructions, the chimney may be
offset using a 30-deg (SL1130) offset/return.

An offset and return may be attached together or a chimney
section(s) may be used between an offset and return.

Perform the following steps to determine the correct chim­ney component combination for your particular installation:

WARNING

Fire Risk

• Draft will be restricted if offsets/returns
greater than 30° are used.

Table 5.2

• Measure how far the chimney needs to be shifted to enable
it to avoid the overhead obstacle. See Figure 5.1. Use
dimension “A” to determine chimney section required to
achieve the needed shift.

• After determining the offset dimension, refer to Table 5.2
and fi nd the “A” dimension closest to but not less than the
distance of shift needed for your installation.

• The “B” dimension that coincides with the “A” dimension
represents the required vertical clearance that is needed
to complete the offset and return.

• Read across the chart and fi nd the number of chimney
sections required and the model number of those particular
chimney parts.

• Whenever the chimney penetrates a fl oor/ceiling, a ceiling
fi restop must be installed.

• The effective height of the fi replace assembly is measured
from the base of the fi replace to the top of the starter collar.
See Dimensions in Section 12.

Figure 5.1 Chimney Offset/Return

Example: Your “A” dimension from Figure

5.3 is 14-1/2 in. (368 mm). Using Table 5.2
the dimension closest to, but not less than
14-1/2 in. (368 mm) is 14-5/8 in. (371
mm) using a 30° offset/return. It is then
determined from the table that you would
need 33 in. (838 mm) (Dimension “B”)
between the offset and return. The chimney
components that best fi t your application are
two SL412s.

C. Assemble the Chimney Sections

Attach either a straight chimney section or an offset to the
top of the fi replace (depending on your installation require­ment). Chimney sections are locked together by pushing
downward until the top section meets the stop bead on the
lower section.

The inner fl ue is placed to the inside of the fl ue section below
it. The outer casing is placed outside the outer casing of the
chimney section below it. See Figure 5.2.

Note: The ceiling fi restop MUST be nailed to the bottom
of the ceiling joists EXCEPT when the space above is
uninsulated and the attic insulation shield is not being used
(see Figure 5.5). When the attic insulation shield is used
the ceiling fi restop may be above or below the joist of an
insulated ceiling.

WARNING

Fire Risk

Do NOT install substitute or damaged
chimney components.

• MUST use chimney system described in
this manual.

• NO OTHER chimney components may
be used.

Substitute or damaged chimney components
may impair safe operation.

D. Install the Ceiling Firestops

• Mark and cut an opening in the ceiling for the ceiling
fi restop being used. See Figure 5.3.

• Frame the opening with the same size lumber used in the
ceiling joists.

• Install the ceiling fi restop.

Note: Use same dimensional lumber for framing

ceiling firestop and joists.

Note: You must provide support for the pipe during

construction and check to be sure inadvertent loading has
not dislodged the chimney section from the fi replace or at
any chimney joint.

CAUTION

• Ceiling fi restops must be used at ceiling/fl oor.

• Chase construction requires ceiling fi restops at each
fl oor or every 10 ft ( 3.05 m) of clear space.

• Use same dimensional lumber as joists.

Ceiling fi restop slows spread of fi re and reduces cold air
infi ltration.

E. Install the Attic Insulation Shield

An insulation shield must be installed when there is a pos­sibility of insulation coming into contact with the factory built
chimney system.

• Bend the tabs at the top of the attic insulation shield inward.
This will help keep the chimney section centered in the
shield.

• Position the shield over the vertical chimney section where
it penetrates a ceiling fi restop.

• Slide the shield down until it rests on the ceiling fi restop.
The ceiling fi restop will support the insulation shield. See
Figures 5.4 and 5.5.

• ALWAYS maintain specifi ed clearances
around chimney and ceiling fi restops.

• Install ceiling fi restops as specifi ed.

Failure to keep insulation or other material
away from chimney pipe may cause fi re.

F. Double-check the Chimney Assembly

Continue assembling the chimney sections up through the
ceiling fi restops as needed. While doing so, be aware of the
height and unsupported chimney length limitations given un­der Section 5.A. Chimney Requirements.

Check each section by pulling up slightly from the top to en­sure proper engagement before installing the succeeding
sections. If they have been connected correctly, they will not
disengage when tested.

G. Secure the Chimney

When offsets and returns are joined to straight pipe sections,
they must be locked into position with the screws provided*
(outer only), using the predrilled holes. To prevent gravity
from pulling the chimney sections apart, the returns and the
chimney stabilizers have hanger straps for securing these
parts to joists or rafters. See Figure 5.6.

Operating Instructions

WARNING

Fire Risk

• Do not operate fireplace before
reading and understanding operating
instructions.

Failure to operate fi replace properly may
cause fi re.

A. General Information

Fireplaces, as well as other woodburning appliances, have
been used safely for many years. It has been our experience
that most problems are caused by improper installation and
operation of the fi replace. Make certain that installation and
operation of the fi replace system is in accordance with these
instructions.

It is extremely important that the fi re be supervised when­ever the fi replace is in use. It is also recommended that an
annual inspection be performed on the fi replace system to
determine if the fl ue system needs to be cleaned, or as in
the case of any appliance, if minor repairs are required to
maintain the system in top operating condition.

WARNING

HOT! DO NOT TOUCH.
SEVERE BURNS MAY RESULT.
CLOTHING IGNITION MAY RESULT.

Glass and other surfaces are hot during
operation and cool down.

• Keep children away.

• CAREFULLY SUPERVISE children in same room as
fi replace.

• Alert children and adults to hazards of high
temperatures.

• Do NOT operate with protective barriers removed.

• Keep clothing, furniture, draperies and other
combustibles away.

WARNING

Fire Risk

• For use with solid wood fuel or decorative gas
appliance only.

• Do not install unvented gas logs.

B. Outside Air

A source of air (oxygen) is required in order for combustion
to take place. Whatever air is consumed by the fi re must be
replaced through cracks around windows, under doors, etc.
Most newly constructed houses or existing homes fi tted with
tightly sealed doors and windows are relatively air tight. In
this case, an outside air source must be made available to
feed combustion air from outside the home.

An outside air control handle allows you control of the out­side air inlet if your fi replace is equipped with this option.
Use of outside air for combustion is highly recommended to
conserve heated air within the structure and to provide make
up air to keep the fi replace venting properly.

This fi replace will operate correctly only if adequate ventila­tion is provided to allow proper draft to the fi replace sys­tem.

See Figure 9.1 for location and operation.

CAUTION

E. Firescreen

A fi rescreen is always provided to control sparks. It must
be closed whenever the fi replace is in use. Glass doors or
fi rescreens must not be used to hold burning material in­side the fi replace. Only those glass doors specifi cally tested
and listed for use with the specifi c fi replace model should be
used. Screens should be closed when the glass doors are
closed.

WARNING

Fire Risk

• Close fi rescreen when burning fi replace.

• Do not use fi rescreen or glass doors to

hold burning material in fi replace.

Firescreen controls sparks.
Glass may break or burning material may

roll out.

Outside air control handle is HOT. Adjust before lighting
fi re.

C. Clear Space Near the Fireplace

Combustible materials must not be stored on the hearth ex­tension. Room furnishings such as drapes, curtains, chairs
or other combustibles must be at least 4 ft (1.22 m) from the
open front of the fi replace.

D. Flue Damper

The fl ue damper must be in full open position, and is oper­ated by moving the handle up toward the top of the fi replace.
Before lighting the fi re, verify this by looking up from the in­side of the fi replace. Always operate this fi replace with the
damper fully open. Please note: Down drafts, obstructions,
damaged or poor (wet) fuels can cause smoke spillage.

See Figure 9.1 for location and operation.

WARNING

Asphyxiation Risk
Fire Risk

• Open damper to operate fi replace.

F. Glass Doors

Most effi cient fi replace operation using glass doors is with
the doors open. When the doors are open the screen must
be closed. Only Hearth & Home Technologies glass doors
may be used. See Figure 9.2 for proper glass door opera­tion.

G. Grate

The factory installed integral grate must be used to hold the
logs from falling out of an open fi replace and to allow air to
pass between the burning logs. It is important to keep the fi re
off the hearth and to allow the ashes to collect beneath the
fi re, thereby forming a layer of additional heat protection.

WARNING

Fire Risk

• Use only factory installed integral grate.

May cause overfi re.

H. Wood Fuel

Firewood

Your fi replace performance depends on the quality of the
fi rewood you use. All seasoned wood, regardless of spe­cies, contains about 8,000 BTU’s per pound, and hard­woods have a greater density than soft woods. A piece
of hardwood will contain about 60% more BTU’s than
an equal size piece of soft wood. Firewood is commonly
sold by the cord (128 cu. ft.). A cord of seasoned oak
(hardwood) would contain about 60% more potential en­ergy than a cord of seasoned pine (soft wood).

Examples of soft wood trees are Douglas fi r, pine, spruce,
and cedar, poplar, aspen and alder. Soft woods require
less time to dry, burn faster and are easier to ignite than
hardwoods.

Examples of hardwood trees are oak, maple, apple, and
birch. Hardwoods require more time to season, burn
slower and are usually harder to ignite than soft woods.

The best wood fuel is a combination of soft wood and
hardwood. Start the fi re with soft wood; the fi re will give
off quick heat to bring the fi replace up to operating tem­perature, and then the hardwood can be added for slow,
even heat and longer burn time.

Moisture

Regardless of which species of wood you burn, the single
most important factor that effects the way your fi replace
operates is the amount of moisture in the wood. The ma­jority of the problems fi replace owners experience are
caused by trying to burn wet, unseasoned wood.

Freshly cut wood can be as much water as it is wood,
having a moisture content of around 50%. 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.

Seasoning

Seasoned fi rewood is nothing more than wood that is
cut to size, split and air dried to a moisture content of
around 20%. The time it takes to season wood varies
from around nine months for soft woods to as long as
eighteen months for hardwoods. The key to seasoning
wood is to be sure it has been split, exposing the wet
interior and increasing the surface area of each piece. A
tree that was 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.

The following guideline will ensure properly seasoned
wood:

• Stack the wood to allow air to circulate freely around
and through the woodpile.

• Elevate the woodpile off the ground to allow air
circulation underneath.

• The smaller the pieces, the faster the drying process.
Any piece over 6 in. (152 mm) in diameter should be
split.

• Cover the top of the woodpile for protection from
rain and snow. Avoid covering the sides and ends
completely. Doing so may trap moisture from the
ground and impede air circulation.

The problems with burning wet, unseasoned wood are
twofold: First, you will receive less heat output from wet
wood because it requires energy in the form of heat to
evaporate the water trapped inside. This is wasted ener­gy that should be used for heating your home. Secondly,
this moisture evaporates in the form of steam which has
a cooling effect in your fi replace and chimney system.
When combined with tar and other organic vapors from
burning wood it will form creosote which condenses in
the relatively cool fi replace and chimney.

WARNING

Fire Risk

• Do NOT burn wet or green wood.

• Store wood in dry location.

• Stack wood so both ends are exposed to
air.

Wet, unseasoned wood can cause
accumulation of creosote.

WARNING

Fire Risk

Do NOT store wood:

• Closer than required clearances to
combustibles to fi replace.

• Within space required for loading or ash
removal.

I. Starting a Fire

Check the fl ue damper to be certain it is in the full open po­sition. Place crumpled or twisted paper under the fi replace
grate. Loosely arrange kindling or small pieces of wood to
form a layer above the paper.

The fi res must be built on the fi replace grate, without danger
of the burning fuel falling out of the fi replace opening.

Light the paper and add small pieces of wood until a hot bed
of embers has been established.

After establishing the fi re bed, and the small fi rewood is burn­ing briskly, add a minimum of three average sized pieces of
split fi rewood, place the wood in such a manner to allow
combustion air and fl ames between them.

Note: When fi rst lighting your fi replace, it may be necessary
to pre-warm the fl ue to establish a draft. This is done by
holding a rolled up piece of burning newspaper under the
fl ue damper for a few moments. This will help reduce smoke
spillage during start-up.

Note: 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 refractory and paint to cure. You may
not ice an indu s t r ial odor the fi rst few fi res. This is considered
normal.

CAUTION

Odors and vapors released during initial
operation.

• Curing of high temperature paint.

• Open windows for air circulation.
Odors may be irritating to sensitive individuals.

WARNING

Fire Risk

Keep combustible materials, gasoline and
other fl ammable vapors and liquids clear of
fi replace.

• Do NOT store fl ammable materials close
to the fi replace.

• Do NOT 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 such liquids well away from the
fi replace while it is in use.

Combustible materials may ignite.

exhaust fans off; open window slightly. Perform Simplifi ed
House Pressure Test.

I don’t get enough/any heat from the fi replace. What can I do about it?

Diagnostic Questions Possible Causes of Condition Solutions

How much wood is used for fi re? • Insuffi cient fuel Make larger fi res.

How well seasoned is the wood? • Condition of fuel Burn seasoned wood: covered on top, split and stacked for

9 months to 2 years.

How much heat output do you
expect?

• Unrealistic expectations Explanation of decorative nature of fi replace; suggestion of

approved fi replace insert.

The fi replace burns the wood too fast. What can I do?

Diagnostic Questions Possible Causes of Condition Solutions

Do you have glass doors? • Need to slow air intake Add glass doors.

What is the condition of the
wood?

• Extremely dry wood Mix in less seasoned wood after fi re established.

Maintenance and Servicing the Fireplace

A. Disposal of Ashes

Ashes should be placed in a metal container with a tight-fi t­ting lid. The closed container of ashes 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 embers have thoroughly cooled.

WARNING

Fire Risk

Disposal of ashes

• Ashes should be placed in metal container with tight
fi tting lid.

• Do not place metal container on combustible
surface.

• Ashes should be retained in closed container until all
embers have thoroughly cooled.

WARNING

B. Chimney Inspection/Cleaning

Inspect the chimney internally for obstructions and construc­tion damage. Flue pipe joints and seams must be continu­ous and mechanically tight.

The chimney should be inspected once every two months
during the heating season.

If creosote has accumulated, it should be removed to reduce
the risk of a chimney fi re.

Refer to Figure 11.1 to remove/reinstall termination caps.

C. Firebox Refractory

Check fi rebox refractory for excessive cracks or gaps. If
cracks exceed 1/4 in. (6 mm) in width the refractory should
be replaced. See Section 12 for replacement information.

WARNING

Fire Risk

• Inspect fi replace refractory annually.
Crumbling, deteriorated refractory can allow

overheating of surrounding materials.

E. Chimney Fire

In the event of a chimney fi re:

• Have the chimney and adjacent structure inspected by
qualifi ed professionals. Hearth & Home Technologies
recommends that NFI or CSIA certifi ed professionals, or
technicians under the direction of certifi ed professionals,
conduct a minimum of an NFPA 211 Level 2 inspection
of the chimney.
