C. Constructing the Appliance Chase
NOTICE: Install appliance on hard metal or wood surfaces
extending full width and depth. DO NOT install directly on
carpeting, vinyl, or any combustible material other than
wood.
WARNING! Risk of Fire! Maintain specied air space
clearances to appliance and vent pipe:
• Insulation and other materials must be secured to prevent
accidental contact.
• The chase must be properly blocked to prevent blown
insulation or other combustibles from entering and
making contact with replace or chimney.
• Failure to maintain airspace may cause overheating and
a re.
A chase is a vertical box-like structure built to enclose the
gas appliance and/or its vent system. In cooler climates
the vent should be enclosed inside the chase.
NOTICE: Treatment of ceiling restops and wall shield
restops and construction of the chase may vary with the
type of building. These instructions are not substitutes
for the requirements of local building codes. Therefore,
you MUST check local building codes to determine the
requirements to these steps.
NOTICE: Where required by code, install only sprinkler
heads with a sprinkler activation temperature classied
as Extra High.
• Sprinklers inside of chase: Keep sprinkler head away
from vent and chimney.
• Heat Management applications: Maintain 36 inches of
clearance to openings from which heat is discharged
such as convection slots, passive heat registers, heat
zone registers, etc. Refer to Section 6.B for Heat
Management options allowed for this appliance.
Chases should be constructed and insulated in the same
manner as the thermal envelope of the home based on
the code requirements for that climate zone to prevent air
leakage and draft problems. The chase is an extension of
the building thermal envelope.
To further prevent drafts and air leakage, the wall shield
and ceiling restops should be sealed with caulk with
a minimum of 300 ºF continuous exposure rating to
seal gaps. Gas line holes and other openings should
be sealed with caulk with a minimum of 300 ºF continuous exposure rating or stued with unfaced insulation. If the
appliance is being installed on a cement surface, a layer of
plywood may be placed underneath to prevent conducting
cold up into the room.
Minimum height requirements for an exterior chase on a topvented appliance are shown in Figure 3.12. Reference Figure 4.5 for additional clearances.

Measuring Standards:
Vertical and horizontal measurements listed in the vent
diagrams and clearances for termination were made
using the following standards:
• Pipe measurements are shown using the eective length
of pipe. See Section 12.A (Figure 12.1) for information
on eective length of pipe components.
• Horizontal terminations are measured to the outside
mounting surface (flange of termination cap). See
Figure 4.8.
• Vertical terminations are measured to top of last section
of pipe. See Figure 4.9.
• Horizontal pipe installed level with no rise.
E. Use of Flex Vent (SLP-FLEX Series 6-5/8
Inch)
The ex vent must be supported with the spacing between
support intervals not exceeding 4 feet, with no more than
1/2 inch sag between supports.
A support is required at each change in venting direction, and in any location where it is necessary to maintain
the necessary clearance to combustibles. A simple “up
and out” installation (Figure 4.10) requires only enough
support to maintain the necessary clearance to combustibles. However, the vent attachment point and the restop
location are considered to be supports.

General Rules:
• SUBTRACT 3 ft from the total H measurement for each
90º elbow installed horizontally.
• SUBTRACT 1-1/2 ft from the total H measurement for
each 45º elbow installed horizontally.
• A maximum of three 90º elbows (or six 45º elbows) may
be used in any vent conguration. Some elbows may be
installed horizontally. See Figure 4.15.
• Elbows may be placed back to back anywhere in the
system.
• Any 90º elbow may be replaced with two back to back
45º elbows.
• When penetrating a combustible wall, a wall shield
restop must be installed.
• When penetrating a combustible ceiling, a ceiling restop
must be installed.
• Horizontal runs of vent do not require vertical rise;
horizontal runs may be level.
• Horizontal termination cap should have a 1/4 inch
downward slant to allow any moisture in cap to be
released. See Figure 4.11.

Combustible Wall Penetration
Whenever a combustible wall is penetrated, you must
frame a hole for the wall shield restop(s). The wall shield
restop maintains minimum clearances and prevents cold
air inltration.
• The opening must be framed on all four sides using the
same size framing materials as those used in the wall
construction.
• SLP pipe - A wall shield restop must be placed on each
side of an interior wall. A minimum 1-1/2 in. (38 mm)
overlap of attached heat shields must be maintained.
• See Section 7.F for information for regarding the installation of a horizontal termination cap.
Non-Combustible Wall Penetration
If the hole being penetrated is surrounded by non-combustible materials such as concrete, a hole with diameter
one inch greater than the pipe is acceptable.
Whenever a non-combustible wall is penetrated, the wall
shield restop is only required on one side and no heat
shield is necessary.

• Seal gaps between the nished wall and appliance
top and sides using a 300 ºF minimum sealant. Refer
to Figure 10.1 and Figure 10.2.
NOTICE: Surface temperatures around the appliance will
become warm while the appliance is in operation. Ensure
finishing materials used for all surfaces (floor, walls,
mantels, etc.) will withstand temperatures up to 190°F.
WARNING! Risk of Fire! Comply with all minimum clearances to combustibles as specied. Framing closer than the
minimums listed must be constructed entirely of noncombustible materials (i.e., steel studs, concrete board, etc.)
The appliance is designed to accept 1/2 in. wall sheathing
materials such as drywall, plywood, wood composites, or
non-combustible materials. The type of material used
depends whether the installation is an Inside or Overlap
Fit Method. Refer to Section 10.D regarding installation
details associated with the Inside and Overlap Fit
methods.
The factory-supplied non-combustible board must be
used in all installations. It must be directly attached to
structural framing adjacent to the appliance. Screw fasteners should be installed in the pilot holes provided in
the outer perimeter of the non-combustible board. See
Figure 10.1 and Figure 10.2.
The factory-supplied board is designed such that its edges will be at the approximate center of the adjacent framing, assuming it is 1-1/2 in. nominal thickness. This will
allow the wallboard joints to occur on the center of the
framing where the panels can be fastened properly. If the
framing thickness is less than 1-1/2 in. nominal, such as
with formed steel systems, then it may be necessary to
adjust the adjacent framing dimensions so that the noncombustible board and wallboard joints are centered on
the framing.
Finishing Instructions
It is important to follow the framing and nishing instructions to ensure proper placement of replace into the surrounding framing/nishing materials.
Wall sheathing materials 1/2 in. thick are specied in
this installation manual to properly align with the factoryinstalled non-combustible material.
WARNING! Risk of Fire! DO NOT remove the factoryinstalled non-combustible board or cover it with combustible material, such as:
• Drywall (gypsum board)
• Plywood
• Materials that do not meet the ASTM E 136 Noncombustibility standard (below).
Removal of factory-installed, non-combustible board and/
or use of materials not meeting the ASTM E 136 standard
may cause re.
• Facing and/or nishing materials must not interfere with
air ow through decorative barrier fronts.
• Facing and/or nishing materials must never overhang

Introduction
If the desired nished replace installation does not utilize
non-combustible nishing materials (such as tile, marble,
stone, etc.), special attention must be paid to the installation of drywall/gypsum wallboard to the side joints of
the non-combustible board to minimize potential development of cracking and paint discoloration. Hearth and
Home Technologies has tested the following methods and
materials and therefore recommends the following steps
for the best drywall performance.
Attaching Non-Combustible Board to Framing
1. To ensure the lower cover panel has been correctly
installed, verify that two screws (total) have been
installed in the lower left and right sides of the replace opening. See Figure 8.1. These screws, when
installed, will ensure the lower panel is correctly installed. If the lower cover panel is not correctly installed, the decorative barrier front may not t into the
replace opening correctly. Refer to section 6.D for
more information regarding the included non-combustible board.
2. The appliance ships with the required non-combustible board. The large top piece of non-combustible
board is pre-installed at the factory. The narrow left
and right non-combustible pieces are shipped within
the appliance. Install the non-combustible side pieces
with the screws provided in the manual bag assembly.
There are pilot holes located on the left and right side
columns. Care should be taken not to tighten these
screws into the non-combustible board excessively.
Set screws ush to the face of the non-combustible
board. See Figure 10.2 and Section 6.D.
3. The outer perimeter of the factory-installed non-combustible board has pre-drilled pilot holes. See Figure
10.1. Secure the non-combustible board to adjacent framing with drywall screws that are a minimum
of 1-1/4 inch in length. Care should be taken not to
tighten these screws into the non-combustible board
excessively. Set screws ush to the face of the noncombustible board. See Figure 10.2 and Section 6.D.
4. When installing drywall around the appliance, install
a rectangular hole for the replace/non-combustible
board in a single sheet of drywall. This will minimize
the joints that require nishing adjacent to the replace
opening. Ensure that the 1/8 inch gap is maintained
between the factory installed non-combustible board
and the surrounding drywall. See Figure 10.1. Secure
the drywall to the framing with screws a minimum of
one inch in length every six inches across the top of
the replace and every ten inches on the sides of the
replace.

5. To ensure good adhesion of drywall compounds and
tape, thoroughly clean the non-combustible board and
surrounding drywall to remove dust. The non-combustible board may be primed with a high-quality PVA
primer.

PILOT HOLES
Figure 10.1 Install Non-Combustible Board
Filling and Finishing Seams
1. Step 1: Fill all gaps and joints between the noncombustible board pieces and the drywall with a
general purpose chemically setting joint compound
such as Durabond® 45 Joint Compound manufactured
by USG (Sheetrock® brand), recommended by Hearth
& Home Technologies. Use a drywall knife to rmly
press the joint compound into all gaps. See Figure
10.1. Allow these joints to dry.
2. Step 2: All joints are to be taped with berglass mesh
tape 1 7/8” minimum width, and embedded with
Setting-Type joint compound, such as with Durabond®
Joint Compound manufactured by USG (Sheetrock®
brand), or equivalent. Allow these joints to dry.
3. Step 3: Depending on the technique used in steps
1 and 2, two to three nishing coats are required to
provide a smooth and durable nish. Hearth and
Home Technologies recommends a lightweight or allpurpose compound. Allow each coat to properly cure.
Allow the nishing coat(s) to cure for 24 hours before
operating appliance.
NOTICE: Hearth & Home Technologies recommends
using multiple pieces of decorative nish material around
the opening of the appliance to reduce the chances of
the material cracking. A single piece of decorative nish
material (such as marble or granite) is more susceptible
to cracking due to uneven heating and cooling which
causes temperature dierentials within the material itself.
The use of multiple pieces will reduce the temperature
dierentials in each piece and reduce the likelihood of
cracks. In addition to using multiple pieces of decorative
nish material, the installation of the Passive Heat optional
heat management system will also reduce the chances of
cracking.
Page 61
Painting
If desired nishing includes a painted wall, a high-quality
100% acrylic latex paint with a high-quality latex primer
base coat are recommended around the appliance to limit
discoloration. Oil-based or standard acrylic paints may
be more prone to discoloration due to heat exposure.
Drywall Joint-Crack Prevention and Repair
Drywall joints around the replace will be aected by exposure to elevated temperatures, along with other environmental, structural factors due to new construction, and
methods used to install and nish the drywall. If a crack
does emerge adjacent to the replace, it can be permanently repaired by lling it with a paintable latex caulk,
followed by repainting.
Some movement of the screws used to secure the noncombustible board to the appliance/surround framing is
expected. If a blemish begins to show over a screw head,
sand the surface to remove the blemish and repaint.
WARNING! Risk of Fire! Maintain specied air space
clearances to combustibles. Inadequate air space could
cause overheating and re.
WARNING! Risk of Fire! Maintain specied air space
clearances to combustibles. Failure to comply with
these instructions may cause a re or cause the appliance to overheat.
CAUTION! Risk of Glass Damage and Cuts! DO NOT
drill or install any type of screw or fastener into the lower
cover panel. Sharp screw or fastener tips may penetrate
and break the glass or cause cuts.
The nal replace installation can be accomplished by
either the Overlap Fit or Inside Fit method. Reference
Section 10.D regarding installation details associated
with the Inside Fit and Overlap Fit methods.
It is acceptable to pre-drill holes and use self-tapping
screws in the installed non-combustible board to attach
non-combustible backer board for tile, marble, etc. Refer
to Figure 10.2 for acceptable screw or metal lath location
and screw length requirements.
Do not drill or install screws which may penetrate the
lower cover panel as this will restrict required access
to the glass, battery-backup, and control module. See
Figure 10.2.
Note: If the desired look is painted drywall, it is
recommended that no additional screws are installed into
the factory-provided non-combustible board. Only install
the screws provided into the pilot holes located in the
factory-provided non-combustible board.

I. Fixed Glass Assembly Removal and Re-
placement
WARNING! Risk of Asphyxiation! Handle xed glass
assembly with care. Inspect the gasket to ensure it is
undamaged and inspect the glass for cracks, chips or
scratches.
• DO NOT strike, slam or scratch glass.
• DO NOT operate replace with glass removed, cracked,
broken or scratched.
• Replace as a complete assembly.
Removing Fixed Glass Assembly
1. Remove the decorative front.
2. The glass assembly has two upper spring latches
and two lower spring latches. See Figure 11.3. Locate the two spring latches that are on the upper left
and right of the replace.
3. Pull upper spring latch on one side forward to release
glass assembly while supporting glass assembly with
opposite hand. Repeat for the other upper spring
latch always taking care to support the glass assembly with one hand.
4. Grasp glass on the upper right and left sides and
remove glass assembly by lifting “up” and “out”.
Note: Observe the presence of a space or gap between
the glass latch and the front of the appliance where the
bottom of the glass assembly is positioned. This gap is
designed for positive placement when replacing the glass
assembly. See Figure 11.3.
Replacing Fixed Glass Assembly
The bottom glass latches have been designed to create
a small gap between the glass clip and the face of the
appliance. See Figure 11.3.
1. Install the bottom of the glass assembly so that the
two tabs on the bottom of the glass latch engage the
gap. By tilting the top of the glass towards the face of
the appliance, tension will be applied to the bottom
two glass latches. Use one hand to support the glass
at all times.
2. Fasten the two upper glass latches, one at a time, by
pulling out and downward into position on the glass
assembly. Use one hand to support the glass at all
times.
3. Verify that the top two glass latches are engaged by visually verifying that glass latches have engaged both
left and right tabs on the glass frame.
4. Verify the bottom two glass latches have engaged the
glass frame tabs by grasping the bottom of the glass
frame assembly and pulling the glass frame assembly
“away” from the face of the appliance and “release”
the glass frame. The spring action of the clips will
“pull” the glass frame assembly towards the face of
the appliance if bottom clips are properly engaged. If
the glass frame assembly does not pull back towards
the face of the appliance, repeat steps 1-4.
