B. Design and Installation Considerations
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, re
ofcials or authorities having jurisdiction over restrictions,
installation inspection and permits.
• Before installing, determine the following:
- Where the replace is to be installed.
- The vent system conguration to be used.
- Gas supply piping.
- Electrical wiring.
- Framing and nishing details.
- Whether optional accessories - devices such as a
fan, wall switch or remote control - are desired.
1. Selecting Fireplace Locations
This replace may be used as a room divider, installed
along a wall, across a corner or used in an exterior chase.
See Figure 2.2.
Locating the replace in a basement should be avoided.
Locating near frequently opened doors, central heat
outlets or returns, or other locations of considerable air
movement can affect the performance.
Outside air must be used for combustion. This replace
comes equipped with an outside air inlet to feed combus-
tion air from outside the home, along with an outside air
termination cap; the rigid metal duct is required but not
supplied. Consideration should be given to these factors
before deciding on a location.

Heatilator • SC60 Installation Manual • 4013-281 • Rev F • 05/06/15
2. Locating Fireplace & Chimney
Location of the replace and chimney will affect perfor-
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 re.
• Installing the replace in a basement is not recommended.
• 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 replace location relative to oor and ceiling
and attic joists.
• Take into consideration the termination requirements in
Sections 4 and 5.
Marginal Location:
• Below peak
Location NOT recommended:
• Not the highest point of the roof
• Wind loading possible
Multi-level Roofs
Windward
Leeward
Recommended Location:
• Above peak
Recommended:
• Insulated exterior chase
in cooler climates
Recommended Location:
• Above peak
• Inside heated space
Location NOT recommended:
• Too close to tree
• Below adjacent structure
• Lower roof line
• Avoid outside wall
Marginal Location:
• Wind loading possible
Figure 2.3 Recommended Chimney Locations
• Install the outside air kit with the intake facing prevailing
winds during the heating season.
• 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 replace.
• Avoid installing the 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.

C. Construct the Chase
A chase is a vertical boxlike structure built to enclose the
replace and/or its vent system. Vertical chimneys that
run on the outside of a building must be installed inside a
chase.
In cold climates, Hearth & Home Technologies recom-
mends that the chase be well insulated using batt type
insulation between the joists.
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.
Chases 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 restops/
attic shields at each oor of the chase or every 10 ft (3048
mm) of clear space to control spread of re.
Walls, ceiling, base plate and cantilever oor at the rst
level of the chase should be insulated (see Figure 3.3.)
Vapor and air inltration barriers should be installed in the
chase as per regional codes for the rest of the home. Ad-
ditionally, Hearth & Home Technologies recommends that
the inside surfaces be drywalled and taped (or the use of
an equivalent method) for maximum air tightness.
Holes and other openings should be caulked with high
temperature caulk or stuffed with unfaced berglass insu-
lation.

Figure 3.4 Chase Constructions
1. Fireplace and chimney enclosed in an exterior chase.
2. Chimney offset through exterior wall and enclosed in chase.
3. Chase constructed on roof.
• The chase is constructed using framing materials much
the same as the walls in your home. A variety of siding
materials may be used including brick, stone, veneer
brick, or standard siding materials.
• In constructing the chase, several factors must be
considered:
- Maintain a 2 in. (51 mm) air space around the
chimney.
- The chase top must be constructed of non-
combustible material.
- In cold climates, a restop spacer and attic insulation
shield should be installed in an insulated false ceiling
at the 8 ft. (2438 mm) level above the replace
assembly. This reduces heat loss through the chase.
- In cold climates, the walls of the chase should be
insulated to the level of the false ceiling as shown in
Figure 3.3. This will help reduce heat loss from the
home around the replace.
Three examples of chase applications are shown in Fig-
ure 3.4.
WARNING! You must install false ceilings and ceil-
ing restops at each oor of the chase or every 10 ft
(3.05 m) to control spread of re.
WARNING! Risk of Fire! DO NOT sealareabetween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rmlysecuredto
prevent accidental contact with chimney system.
• Thechasemustbeproperlyblockedtopreventblown
insulation or other combustibles from entering and
makingcontactwithreplaceorchimney.
• Failuretopreventcontactbetweeninsulationorother
materials and chimney system may cause overheating
andre.

D. Frame the Fireplace
NOTICE: Hearth extension design must be determined
before installation of replace.
If the replace is placed on the oor the maximum height
of a nished raised hearth is 0 in., if you want a higher
raised hearth the replace must be placed on a platform.
NOTICE: Wiring for fans must be done before framed
enclosure is completed.
WARNING! Risk of Fire! Youmustcomplywithall
minimum air space clearances to combustibles. DO NOT
packrequiredairspaceswithinsulationorothermateri-
als.
WARNING! Risk of Fire! Comply with all minimum clear-
ancesspecied.
• A minimum 1/2 in. (13 mm) air clearance must be
maintainedatthebacksidesofthereplaceassembly.
• Chimneysectionsatanylevelrequirea2in.(51mm)
minimum air space clearance between the framing and
chimney section.
Figure 3.5 shows a typical framing (using 2 x 4 lumber)
of the replace, assuming combustible materials are
used. All required clearances to combustibles around the
replace must be adhered to. See Figure 3.2. Any framing
across the top of the replace must be above the level of
the top standoffs. (No recess above standoffs.)
The nished cavity depth must be no less than 25 in.
(635 mm) from the nished backwall to the outside of front
wall framing. Framing must extend straight up all the way
to the ceiling.
CAUTION! RiskofCuts/Abrasions.Wearprotectivegloves
and safety glasses during installation. Sheet metal edges
are sharp.
WARNING! Risk of Fire! Prevent contact with sagging,
loose insulation.
• DO NOT install against vapor barriers or exposed

G. Outside Air Kit
As you install the outside air kit, Hearth & Home Tech-
nologies recommends you utilize the shortest duct run
to optimize the performance of the outside air kit. The
outside air inlet hood should be positioned in a manner
that will not allow snow, leaves, etc. to block the inlet. In
some installations the air duct may need to be run verti-
cally. In such an installation, a 3 ft (914 mm) height differ-
ence must be maintained from the top of the uppermost
chimney section to the outside air inlet hood.
Refer to Figures 3.8 and 3.9 when placing the outside air
inlet hood.
The outside air kit is installed on the right hand side of the
replace.
• Cut a 4 in. (102 mm) hole in outside wall to accommodate
air piping.
• Use 4 in. (102 mm) ex (not supplied) to directly connect
outside air to replace intake. Insulate the pipe to prevent
frost condensation.
• Use the supplied outside air inlet hood.
• Seal between the wall and the pipe with silicone to
prevent moisture penetration and air leaks.
• Seal between the outside air inlet hood and the house
with silicone to prevent air inltration.
CAUTION! Risk of Cuts/Abrasions. Wearprotective
gloves and safety glasses during installation. Sheet metal
edges are sharp.
CAUTION! Risk of Fire or Asphyxiation! DO NOT draw
outsidecombustionairfromwall,oororceilingcavity,or
enclosed spaces such as an attic or garage.
• DO NOT place outside air inlet hood close to exhaust
vents or chimneys. Fumes or odor could be drawn into
theroomthroughthereplace.
• Locateoutsideairinlethoodtopreventblockagefrom
leaves,snow/ice,orotherdebris.Blockagescouldcause
combustion air starvation.

The SC60 is a heat circulating replace that comes
equipped with a fan kit, junction box, and an ON/OFF
variable speed control (wall mount type).
110 VAC service must be connected to the fan kit by a
licensed electrician. See Figure 7.5 for the typical fan kit
wiring diagram and the typical access to the junction box.
Service or Replace the Fan Kit
• Remove the lower replace grille.
• Unplug the blower from the junction box on the replace.
• Remove the screws for the blower mounting brackets
and carefully slide blower out of the replace.
• To reinstall the fan kit, reverse these steps.
We recommend the fan kit be installed at the time of initial
installation of the replace to avoid considerable recon-
struction.
Note: If a spe ed c ontro l opti on is desired, it is recomm ended
that you use the BC10 Motor Speed Control Kit supplied
with the replace to ensure proper functioning. Refer to
the instructions packed with it for proper installation.
WARNING! Risk of Electric Shock! DO NOT remove
grounding prong from plug or route cord under or in front
of appliance. Plug directly into a properly grounded three-
prong receptacle and route cord away from appliance.

B. Offsets/Returns
• 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! Risk of Fire! DO NOT useoffset/returnsgreaterthan30°.Chimneydraftwillberestrictedandcouldcause
overheatingandre.Secureoffsetswithscrews(nottoexceed1/2”/13mminlength)Securereturnswithstrapping.
Straight chimney sections may be secured with screws. Keep chimney sections from separating or twisting.
• Measure the shift needed to avoid the overhead obstruction. Refer to dimension A in Figure 4.2.
• Find the appropriate A dimension listed in Table 4.3. The B dimension coinciding with the A dimension measurement in
Table 4.3 represents the required vertical clearance needed to complete the offset/return.
• Read across the chart to nd the number of chimney sections/model numbers needed between the offset and return.

• Lock chimney sections and/or offsets/returns together by
pushing downward until the top section meets the stop
bead on the lower section.
• Pull on the top section to make sure it is fully engaged
and will not separate.
• You may use #6 or #8 sheet metal screws no longer than
1/2 in. (13 mm) to fasten chimney sections together. Do
NOT penetrate inner ue.

penetrate inner ue.
• Secure chimney returns with hanger straps provided;
fasten to studs or joists.
• Vertical straight runs of chimney must be supported every
35 ft (10.7 m).
B. Assemble Chimney Sections
Use only those components described in this manual.
Substitute or damaged chimney components could impair
safe operation and cause overheating and re.
Attach either a straight chimney section or an offset to
the top of the 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 ue is placed to the inside of the ue section
below it. The outer casing is placed outside the outer cas-
ing of the chimney section below it. See Figure 5.2.
WARNING! Risk of Fire! DO NOT install substitute or
damaged chimney components.
