Getting Started
A. Design and Installation Considerations
Draft is the pressure difference needed to vent replaces
successfully. Considerations for successful draft include:
• Location of replace and chimney
Check building codes prior to installation.
• Installation MUST comply with local, regional,
state and national codes and regulations.
• Consult insurance carrier, local building inspector,
re ofcials or authorities having jurisdiction about
restrictions, installation inspection, and permits.
CAUTION
When planning a replace installation, it is necessary to de-
termine the following information before installing:
• Where the fireplace is to be installed. See Sections
3 and 4.
• The vent system conguration to be used. See Sections
5 and 6.
• Framing and nishing details. See Sections 3, 6 and 8.
• Whether optional accessories are desired. See
Section 12.
Moisture Resistance:
This outdoor replace will shed moderate amounts of water,
but is not waterproof. Water and condensing water vapor
may enter the chase under certain conditions.
The replace will not perform as an exterior wall. Moisture
penetration must be considered for construction that places
the replace in structure walls or on moisture sensitive sur-
faces.
When installed on exterior walls: Hearth & Home Tech-
nologies recommends that the replace chase be con-
structed outside the structure’s weather envelope. Where
the platform meets the wall, use a ashing detail similar to
that required for attached decks. Chase platforms, including
hearths should slope away from the structure at 1/8 in. to
1/4 in. per foot. The replace can be shimmed level.
When installed on surfaces where water may collect or
cause damage: Hearth & Home Technologies recommends
that a drainage pan be placed under the unit. This can be
constructed of metal, adhesive polymer membrane (such as
ice and water shield) or other suitable materials. A means of
drainage out of the pan such as tubes or weep holes should
be provided. A slope of 1/8 in. to 1/4 in. per foot towards
the drain port is suggested. The replace can be shimmed
level.
Hearths should slope away from the front of the replace
and chase at 1/8 in. to 1/4 in. per foot. Spark strips must be
on top of any combustible hearth materials used for moisture
management.

A. Chimney Requirements
Vertical distances are measured from the base of the re-
place.
• Minimum overall straight height is 6 ft 4 in. if the replace
is freestanding and a minimum of 10 ft from a combustible
structure. See Figure 3.2.
• Chimney must extend 2 ft (.6 m) above any portion
of the roof within 10 ft (3 m) of the chimney. Refer to
Figure 6.1.
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 replace assembly to the point where the smoke exits
the termination cap.
• Subtract the effective height of the replace assembly from
the overall height of the 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 replace installation.
• Determine the number of ceiling restops, stabilizers,
roof flashing, etc. required to complete the fireplace
installation.
Table 5.1
• Do NOT connect this fireplace to a chimney flue
servicing another appliance.
• Do NOT connect to any air distribution duct or
system.
CAUTION

B. Using Offsets/Returns
To bypass any overhead obstructions, the chimney may be
offset using an 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 chim-
ney component combination for your particular installation:
• 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 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 nd the number of chimney
sections required and the model number of those particular
chimney parts.
• Whenever the chimney penetrates a oor/ceiling, a ceiling
restop must be installed.
• The effective height of the replace assembly is measured
from the base of the replace to the top of the starter collar.
See Dimensions in Section 12.

C. Assemble the Chimney Sections
Attach either a straight chimney section or an offset to the
top of the replace (depending on your installation require-
ment). Chimney sections are locked together by pushing
downward until the top section meets the stop bead on the
lower section.
The inner ue is placed to the inside of the ue section below
it. The outer casing is placed outside the outer casing of the
chimney section below it. See Figure 5.2.
D. Install the Ceiling Firestops
Where the chimney system is installed in a chase on the
exterior side of the building envelope or as a free standing
installation, restops are not required. Check building codes
prior to installation.
Where the chimney system is on the interior side of the build-
ing envelope, follow the ceiling restop instructions below:
• Mark and cut an opening in the ceiling for the ceiling
restop being used. See Figure 5.3.
• Frame the opening with the same size lumber used in the
ceiling joists.
• Install the ceiling restop.
Note: The ceiling 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 restop may be above or below the joist of an
insulated ceiling.
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 replace or at
any chimney joint.
Note: Inner flue and outer liner sections cannot be
disassembled once locked together. Plan ahead to ensure
the proper installation height is achieved with the selected
chimney components.
• Ceiling restops must be used where chimney pipe
penetrates ceiling/oor.
Ceiling restop slows spread of re and reduces cold air
inltration.
CAUTION
Figure 5.2 Assembling Chimney Sections
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.

E. Install the Attic Insulation Shield
An insulation shield must be installed when there is a pos-
sibility 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 restop.
• Slide the shield down until it rests on the ceiling restop.
The ceiling restop will support the insulation shield. See
Figures 5.4 and 5.5.
F. Double-check the Chimney Assembly
Continue assembling the chimney sections up through the
ceiling restops as needed. While doing so, be aware of the
height and unsupported chimney length limitations given un-
der Section 5.A. Chimney Requirements.
Check each section by pulling up slightly from the top to en-
sure 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.

tension. 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 replace.
C. Flue Damper
The ue damper must be in full open position, and is oper-
ated by moving the handle up toward the top of the replace.
Before lighting the re, verify this by looking up from the in-
side of the replace. Always operate this 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.
E. Glass Doors
Most ef cient 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 opera-
tion.
F. Grate
The factory installed integral grate must be used to hold the
logs from falling out of an open replace and to allow air to
pass between the burning logs. It is important to keep the
re off the hearth and to allow the ashes to collect beneath
the re, thereby forming a layer of additional heat protection.
Fire Risk
• Use only factory installed integral grate.
May cause over re.

G. Wood Fuel
Firewood
Your replace performance depends on the quality of the
rewood you use. All seasoned wood, regardless of spe-
cies, contains about 8,000 BTU’s per pound, and hard-
woods 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 en-
ergy than a cord of seasoned pine (soft wood).
Examples of soft wood trees are Douglas 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 re with soft wood; the re will give
off quick heat to bring the replace up to operating tem-
perature, 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 replace
operates is the amount of moisture in the wood. The ma-
jority of the problems 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 replace and try to burn
it. This sounds ridiculous but that is exactly what you are
doing if you burn unseasoned wood.
Seasoning
Seasoned 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 ener-
gy that should be used for heating your home. Secondly,
this moisture evaporates in the form of steam which has
a cooling effect in your 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 replace and chimney.
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 replace.
• Within space required for loading or ash
removal.

H. Starting a Fire
Check the ue damper to be certain it is in the full open po-
sition. Place crumpled or twisted paper under the replace
grate. Loosely arrange kindling or small pieces of wood to
form a layer above the paper.
The res must be built on the replace grate, without danger
of the burning fuel falling out of the replace opening.
Light the paper and add small pieces of wood until a hot bed
of embers has been established.
After establishing the re bed, and the small rewood is burn-
ing briskly, add a minimum of three average sized pieces of
split rewood, place the wood in such a manner to allow
combustion air and ames between them.
Note: The rst three or four res should be of moderate
size to allow the oils and binders to be burned from the
replace and the refractory and paint to cure. You may
notice an industrial odor the rst few res. This is considered
normal.
Note: When rst lighting your replace, it may be necessary
to pre-warm the ue to establish a draft. This is done by
holding a rolled up piece of burning newspaper under the
ue damper for a few moments. This will help reduce smoke
spillage during start-up.
Odors and vapors released during initial
operation.
• Curing of high temperature paint.
• Open windows for air circulation.
Odors may be irritating to sensitive individuals.
CAUTION
Fire Risk
Keep combustible materials, gasoline and
other ammable vapors and liquids clear of
replace.
• Do NOT store ammable materials close
to the replace.
• Do NOT use gasoline, lantern fuel,
kerosene, charcoal lighter uid or similar
liquids to start or “freshen up” a re in this
replace.
• Keep all such liquids well away from the
replace while it is in use.
Combustible materials may ignite.
WARNING
With outdoor applications, wind may affect the ame
pattern and performance of the replace. Smoke
spillage and sporadic ame extending beyond the
front of the replace may be possible when doors
are open.

A. Disposal of Ashes
Ashes should be placed in a metal container with a tight-t-
ting lid. The closed container of ashes should be placed on
a noncombustible oor or on the ground, well away from all
combustible materials, pending nal disposal. If the ashes
are disposed of by burial in soil or otherwise locally dis-
persed, they should be retained in the closed container until
all embers have thoroughly cooled.
B. Chimney Inspection/Cleaning
Inspect the chimney internally for obstructions and construc-
tion damage. Flue pipe joints and seams must be continu-
ous 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 re.
Refer to Figure 11.1 to remove/reinstall termination caps.

WARNING
Fire Risk
Prevent creosote buildup
• Inspect chimney once every two months during heating
season.
• Remove creosote to reduce risk of chimney re.
• Ignited creosote is extremely HOT.
WARNING
C. Firebox Refractory Replacement
Check 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.
Fire Risk
• Inspect replace refractory annually.
Crumbling, deteriorated refractory can allow
overheating of surrounding materials.

E. Limited Warranty
Outdoor Lifestyles by Hearth & Home Technologies™
Limited Warranty
Hearth & Home Technologies (“HHT”) extends the following warranty for all Outdoor Lifestyles by HHT™
brand products (“Products”) that are purchased from an HHT authorized dealer.
WARRANTY COVERAGE:
HHT warrants to the original owner of the Product at the site of installation, and to any transferee taking
ownership of the Product at the site of installation within one year following the date of original purchase,
that the Product will be free from defects in materials and workmanship at the time of manufacture. After
installation, if covered components 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. This warranty is subject to conditions, exclusions and limitations as described below.
WARRANTY PERIOD:
The warranty period runs for one year, beginning on the earlier of: (i) the date of invoice for the Product;
(ii) in the case of new home construction, the date of first occupancy of the residence or six months after
the date of sale of the Product by an HHT authorized dealer, whichever occurs first; or (iii) the date 24
months following the date of Product shipment from HHT, regardless of the invoice or occupancy date.
WARRANTY CONDITIONS:
• This warranty only covers Products that are purchased through an HHT authorized dealer or
distributor. A list of HHT authorized dealers is available on the HHT branded websites.
• This warranty is only valid while the Product remains at the site of original installation.
• Contact your installing dealer for warranty service. If the installing dealer is unable to provide
necessary parts, contact the nearest HHT authorized dealer or supplier. Additional service fees
may apply if you are seeking warranty service from a dealer other than the dealer from whom
you originally purchased the Product.
• Check with your dealer in advance for any costs to you when arranging a warranty call. Travel
and shipping charges for parts are not covered by this warranty.
WARRANTY EXCLUSIONS:
This warranty does not cover the following:
• Changes in surface finishes as a result of normal use. As a heating appliance, some changes in
color of interior and exterior surface finishes may occur; this is not a flaw and not covered under
warranty.
• Damage to printed, plated, or enameled surfaces caused by fingerprints, accidents, misuse,
scratches, melted items, or other external sources and residues left on surfaces from the use of
abrasive cleaners or polishes.
• Repair or replacement of parts that are subject to normal wear and tear during the warranty
period. These parts include: paint, firebricks, grates, flame guides and the discoloration of glass.
• Minor expansion, contraction, or movement of certain parts causing noise. These conditions are
normal and complaints related to this noise are not covered by this warranty.

Limited Warranty (continued)
• Damages resulting from: (1) failure to install, operate, or maintain the Product in accordance with
the installation instructions, operating instructions, and listing agent identification label furnished
with the Product; (2) failure to install the Product in accordance with local building codes; (3)
shipping or improper handling; (4) improper operation, abuse, misuse, continued operation with

equate ventilation, negative pressure or environmental conditions, including, without limitation:

than those specified in the operating instructions; (7) installation or use of components not
supplied with the Product or any other components not expressly authorized and approved by
HHT; (8) modification of the Product not expressly authorized and approved by HHT in writing;
and/or (9) interruptions or fluctuations of electrical power supply to the Product.
• Non-HHT venting components, hearth components or other accessories used in conjunction with
the Product.
• Any part of a pre-existing fireplace system in which an insert or a decorative gas appliance is
installed.
• The Product’s capability to heat the desired space. Information is provided to assist the consumer
and the dealer in selecting the proper appliance for the application. Consideration must be given
to the Product’s location and configuration and environmental conditions.
This warranty is void if:
• The Product has been over-fired or operated in atmospheres contaminated by chlorine, fluorine,
or other damaging chemicals. Over-firing can be identified by, but not limited to, warped plates or
tubes, rust colored cast iron, bubbling, cracking and discoloration of steel or enamel finishes and
cracking or spalling of refractory or cementitious materials.
• The Product is subjected to prolonged periods of dampness, condensation, ice or snow.
• There is any damage to the Product or other components due to water or weather damage which
is the result of, but not limited to, improper chimney or venting installation.
LIMITATIONS OF LIABILITY:
Repair or replacement in accordance with the provisions of this warranty will be the owner’s exclusive
remedy for and will constitute HHT’s sole obligation under this warranty, under any other warranty
(express or implied), or in contract, tort or otherwise; provided, however, that if HHT is unable to provide
repair or replacement in an expedient and cost effective manner, HHT may discharge all such obligations
by refunding the purchase price of the Product. No employee, agent, dealer, or other person is authorized
to give any warranty on behalf of HHT. TO THE EXTENT ALLOWED BY LAW, HHT MAKES NO OTHER
WARRANTY, EXPRESS OR IMPLIED, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE. HHT WILL NOT BE LIABLE FOR ANY CONSEQUENTIAL
OR INCIDENTAL DAMAGES ARISING OUT OF DEFECTS IN OR USE OF THE PRODUCTS. Some
states do not allow exclusions or limitation of incidental or consequential damages, so these limitations
may not apply to you. This warranty gives you specific rights; you also may have other rights, which vary
from state to state. The duration of any implied warranty is limited to the duration of the warranty period
specified herein.
