2 Getting Started
A. Design and Installation Considerations
Draft is the pressure difference needed to vent fireplaces
successfully. Considerations for successful draft include:
• Location of fireplace 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,
fire officials or authorities having jurisdiction about
restrictions, installation inspection, and permits.
CAUTION
When planning a fireplace 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 configuration to be used. See Sections
5 and 6.
• Framing and finishing details. See Sections 3, 6 and 8.
• Whether optional accessories are desired. See
Section 12.
Moisture Resistance:
This outdoor fireplace will shed moderate amounts of water,
but is not waterproof. Water and condensing water vapor
may enter the chase under certain conditions.
The fireplace will not perform as an exterior wall. Moisture
penetration must be considered for construction that places
the fireplace in structure walls or on moisture sensitive sur-
faces.
When installed on exterior walls: Hearth & Home Tech-
nologies recommends that the fireplace chase be con-
structed outside the structure’s weather envelope. Where
the platform meets the wall, use a flashing 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 fireplace 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 fireplace can be shimmed
level.
Hearths should slope away from the front of the fireplace
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.

3 Framing and Clearances
A. Selecting Fireplace Location
This outdoor fireplace will shed moderate amounts of water,
but is not waterproof. Water and condensing water vapor
may enter the chase under certain conditions.
The fireplace will not perform as an exterior wall. Moisture
penetration must be considered for construction that places
the fireplace against structure walls or on moisture sensitive
surfaces.
• Exterior Walls (see Figure 3.1)
Hearth & Home Technologies recommends that the
fireplace chase be constructed outside the structure’s
weather envelope. Where the platform meets the wall, use
a flashing 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 fireplace
can be shimmed level. Build the outside enclosure out of
standard building materials, being careful to maintain the
minimum air clearances specified in these installation
instructions.
Fire Risk
Provide adequate clearances.
• Around air openings
• To combustibles
• For service access.
Locate fireplace away from traffic areas.
WARNING Note:
• Illustrations and photos reflect typical installations
and are FOR DESIGN PURPOSES ONLY.
•Illustrations/diagrams are not drawn to scale.
•Actual installation/appearance may vary due to
individual design preference.
• Hearth & Home Technologies reserves the right to
alter its products.
• Freestanding Installations (see Figure 3.2)
When installing this fireplace as a freestanding fireplace
on your porch, patio or in your yard, it must be enclosed
to prevent impact damage to the fireplace. The exterior
of the enclosure may be finished 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
fireplace due to the heat the fireplace produces. This can
cause the vinyl siding to deteriorate.
• 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 fireplace can be
shimmed level.
Hearths should slope away from the front of the fireplace
and chase at 1/8 in. to 1/4 in. per foot. Spark strips must
be used on top of any combustible hearth materials used
for moisture management.

A. Chimney Requirements
Vertical distances are measured from the base of the fire-
place.
• Minimum overall straight height is 6 ft 4 in. if the fireplace
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 fireplace assembly to the point where the smoke exits
the termination cap.
• Subtract the effective height of the fireplace assembly from

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 find 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 find the number of chimney
sections required and the model number of those particular
chimney parts.
• Whenever the chimney penetrates a floor/ceiling, a ceiling
firestop must be installed.
• The effective height of the fireplace assembly is measured
from the base of the fireplace to the top of the starter collar.
See Dimensions in Section 12.

1-1/4 in. (32 mm)
OVERLAP
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
15 3/4 in. (400 mm) using a 30° offset/return. It is
then determined from the table that you would need
36 5/8 in. (930 mm) (Dimension “B”) between the
offset and return. The chimney components that best
fit your application are two SL1112s or SL412s.
Fire Risk
• Draft will be restricted if offsets/returns
greater than 30° are used.

C. Assemble the Chimney Sections
Attach either a straight chimney section or an offset to the
top of the fireplace (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 flue is placed to the inside of the flue 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
• Mark and cut an opening in the ceiling for the ceiling
firestop being used. See Figure 5.3.
• Frame the opening with the same size lumber used in the
ceiling joists.
• Install the ceiling firestop.
Note: The ceiling firestop 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 firestop 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 fireplace 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 firestops must be used at ceiling/floor.
• Chase construction requires ceiling firestops at each
floor or every 10 ft ( 3.05 m) of clear space.
• Use same dimensional lumber as joists.
Ceiling firestop slows spread of fire and reduces cold air
infiltration.
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.
Substitute or damaged chimney components
may impair safe operation.

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 firestop.
• Slide the shield down until it rests on the ceiling firestop.
The ceiling firestop 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 firestops 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.

down and drip edge to prevent water from seeping into the
chase. Provide a 1/8 in. (3 mm) gap around the flue pipe
and slope the top downward away from the penetration. See
Figure 6.3.
• All seams must be caulked to prevent leaks.
• A chase installation must use a chase top. Chase tops
are available from your Heat & Glo dealer or may be field
constructed.
• Attach the chase top to the top of the chase.

WARNING
Mark the Exit Point of the Roof
Locate the point where the chimney will exit the roof by plumbing down to the
center of the chimney. Drive a nail up through the roof to mark the center. See
Figure 6.2.
Cut Out the Hole in the Roof
Measure to either side of the nail and mark the 14-1/2 in. x 14-1/2 in.
(368 mm x 368 mm) opening required. This is measured on the horizontal;
actual length may be larger depending on the pitch of the roof. Cut out and
frame the opening. See Chapter 25 of the Uniform Building Code for roof
framing details.
Assemble the Chimney Sections Through the Roof
Continue to add chimney sections through the roof opening, maintaining at
least a 2 in. (51 mm) air space to combustible materials.
Install the Roof Flashing
If a roof flashing is to be used, install the roof flashing appropriate to the
roof pitch and install a round termination cap and storm collar following the
instructions shipped with the cap.
