Read all instructions and warnings carefully before starting installation. Failure to
follow these instructions may result in a possible re hazard and will void the warranty.
The SR/SC Series "A" replaces are solid fuel, woodburning
premium replaces. The SR36A/42A are radiant clean-face
models and the SC36A/42A are circulating models with
removable grilles (louvres). Both models are fully insulated
replaces.
Vermont Castings Group replaces and component parts
have been highly tested and will operate safely when
installed in accordance with instructions provided in this
manual. Carefully read and understand all instructions
beginning installation.
If you notice any damage to replace or component parts,
immediately report damage to your Vermont Castings Group
Fireplaces dealer.
Only use Vermont Castings Group components or the war-
ranty will be voided and a re hazard may be created.
Vermont Castings Group warranty will be voided by and
Vermont Castings Group disclaims any responsibility for
the following actions:
•
•
•
(except for chase
ashings as detailed in Chimney Top installation
instructions).
•
•
Consult local building codes to ensure that you are in com-
pliance installing the replace.
Fireplaces must be vented to the out-of-doors.
Fuels used in gas, woodburn-
ing or oil red appliances, and the products of combus-
tion of such fuels, contain chemicals known to the State
of California to cause cancer, birth defects and other
reproductive harm.
California Health & Safety Code Sec. 25249.6
The replace should not be located in areas that create
drafts (ie: frequently opened doors and central heating air
inlets/outlets) that hamper the normal ow of air into the
re.
If you plan to install a gas log, the gas line should be
installed framing the replace. The gas line must
be installed by a certied gas line installer.

Do not use more than 4 elbows per
chimney.
Attach the straps of the return (top) elbow
to a structural framing member.
The offset (rst) elbow of any pair does
not have straps.
IWF269
The chimney cannot be more than 30˚
(45˚ in Canada) from the vertical plane in
any installation*.
The maximum length of the angled run
of the chimney system is 20 feet. (G
plus H cannot exceed 20 feet.)
A chimney support (Model SKCS8)
is required every 6 feet of angled run of
chimney. Chimney supports are required
for every 30 feet and 60 feet (SK8 pipe)
or 20 feet and 40 feet (3-wall pipe) of ver-
tical chimney height above the hearth.
Determine the offset distance of your
chimney arrangement from the centerline
of the replace to the centerline of the
chimney where it is to pass through the
rst ceiling.
This offset distance may not be
your full offset distance. See Examples 2
and 3.

Installed lengths of chimney sections.
Preplanning an installation is very important to ensure
safety and to save time and money. An installer must
predetermine where a replace will be set and how the
chimney system will be run.
A replace may only be mounted on the following sur-
faces:
1. A at combustible surface.
2. A raised wooden platform.
3. A concrete block or other solid object placed beneath
each of the four (4) corners of the replace.
The replace be spaced 1/2" (13 mm) from a com-
bustible back wall and 1/2" (13 mm) from a combustible
side wall or support. (Page 14, Fig. 20)
Major U.S. building codes specify a minimum chimney
height above the roof top. The “Ten Foot Rule” is a re
safety rule and not a draft rule. To ensure proper draft, it
is recommended that you always meet or exceed the “Ten
Foot Rule,” especially when installing a termination on a
high pitch roof. (Fig. 8)
The key points of the "Ten Foot Rule" are:
1. If the horizontal distance from the chimney to the peak of
the roof is 10' (3 m) or less, the top of the chimney must
be at least 2' (610 mm) above the peak of the roof, but
never less than 3' (914 mm) in height above the highest
point where it passes through the roof.
2. If a horizontal distance from the chimney to the peak of
the roof is more than 10' (3 m), a chimney height refer-
ence point is established on the surface of the roof a
distance of 10' (3 m) from the chimney in a horizontal
plane. The top of the chimney must be at least 2' (610
mm) above the reference point, but never less than 3'
(614 mm) in height above the highest point where it
passes through the roof.
Determine how the chimney will be run, length of run and
chimney components required to complete the job. (Fig. 6)
install a chimney below minimum heights.
In planning a chimney system, it is important to know:
1. The height of a chimney is measured from the hearth
to the exit point on the termination.
2. A chimney cannot be offset more than 30° from a vertical
plane.
3. A chimney may run straight up or it may be necessary
to offset it to avoid obstructions.
4. The maximum length of an angled run (total chimney
system) is 20' (6 m).
5. No more than 2 offsets (4 total 30° elbows in U.S./or
2 total 45° elbows in Canada) per replace may be
used.
6. A guy wire stabilizer is required for chimneys extending
more than 6' (1.8 m) above a roof line.

If you live in a cold climate, it is not required but
that you insulate replace enclosure to
eliminate cold air penetration as much as possible.
Insulate base of replace with a noncombustible insula-
tion rated for a minimum of 300°F. Insulating is
for outside wall installations over a concrete
slab. If replace is installed on a platform, insulation
should be placed on top of the platform replace
is set. (Fig. 10)
When a replace is installed in a chase or on an outside
wall, enclosure should be treated like any outside wall
in a home. Insulation should be installed on the inside
wall as well as the outside wall(s). In a chase, it is also
a good idea to install a restop at the rst ceiling level
above the replace and enclose the chase with sheeting
material. Insulation may then be installed above sheet-
ing material to assure the space around the replace
is totally protected. (Fig. 5)
When installing the chimney, caulk between
outer pipe and restop. It is vital that some air be al-
lowed to ow through this very thin gap.
(Page 14,
Fig. 20)
The chimney system is supported by the replace for
vertical chimney heights less than 30' (9 m) above the
hearth. Chimney supports are required if the vertical height
exceeds 30' (9 m) with SK8 chimneys or 20' (6 m) with 3-
wall chimneys. Locate chimney supports at ceiling holes
or other structural framing at 30' (9 m) (SK8) or 20' (6 m)
(3-wall) heights. Spacing between chimney supports
exceed 30' (9 m) (SK8) or 20' (6 m) (3-wall). Use
Chimney Support Model SKCS8.
Support
provided by elbow straps fullls the support requirement
only if they are spaced as previously described. (A chimney
support is 2¹⁄₂" (64 mm) long when installed.)
Angled chimney runs require a support every 6' (1.8m) in
addition to the elbow straps. Chimney supports are used
for this function. (Fig. 9)
A chase is a vertical box like structure which encloses the
replace and/or chimney. Chases are typically built on the
outside of the house with replace opening cut into the
outer wall of a room. (Page 5, Fig. 5)
If you need help in determining replace location or how
the chimney system should be run, contact your Vermont
Castings Group Fireplaces dealer for assistance.

Framing can be constructed before or after the replace is
set in place, however, most installers build the frame before
setting the replace.
Frame replace with 2 x 4 lumber or heavier materials.
Refer to framing dimensions in Figures 1, 2, 3 or 4 for
basic replace specications.
Framing should be positioned to accommodate
wall covering and replace facing material.
If a circulating replace is to be installed, run the 120 VAC,
60 Hz wiring to the left side of installation. Wiring must
be completed the replace is secured and nish
material applied.
Remove the cover plate and electrical knockout on the
lower left side of the replace and set aside. Follow the
instructions on Page 10 for proper wiring and installation
of the EB1.
If the fan kit is not being installed with the replace, it is
highly recommended that 120 VAC supply be made avail-
able since someone may elect to install a blower at a later
date.
• Wiring should be installed by a certied
electrician.
• Turn off circuit breaker before wiring models.
Once replace is secured, complete wiring the fan kit.
Remove knockout in the center of the back of the EB1
and install listed cable clamps. Feed electrical wire
through listed cable clamp leaving approximately six (6)
inches of wire exposed through the EB1. Secure listed
cable clamp to the wire.
Attach white wire from power source to one (1) wire of
receptacle and secure with nut. Attach black wire from
power source to the other wire of receptacle and secure
with nut. Be sure nuts are secured tightly.
Secure EB1 assembly to inside of electrical box cover-
plate using two screws. Attach cover to face of the EB1
while being careful to position excess wire completely
within the EB1, then attach coverplate to replace.
Refer to optional Model FK12 fan kit assembly installa-
tion instructions for eld installation.
Since you have already preplanned the chimney run,
you should know exactly how the installation is to be ac-
complished — how much pipe is required, the number of
elbows, if any, and type of termination to be used.
REPORT TO YOUR DEALERS ANY PARTS
DAMAGED IN SHIPMENT, SPECIFICALLY CHECK THE

Fireplaces may use Vermont Castings Group model
SK8, or Model S (three wall) chimney systems. The SR/SC
Series "A" Fireplace will accept the SK8 chimney system
as is; but a TWABR adapter collar is required when using
the Model S (triple wall) chimney system. The installation
procedure described in this manual applies to the
SK8 system. Either chimney system may be used, but
be mixed.

To mark the centerline of the ue, put the replace in nal
position and measure out from the wall: 9¹⁄₄" (235 mm).
Mark a spot on the ceiling directly above the replace.
Draw a line parallel to the back wall through this mark.
(Fig. 11)
Using a plumb bob positioned directly over center point
of replace ue collar, mark the ceiling to establish the
chimney center point. (Fig. 11)
In order to clear an obstruction, it may be necessary to
offset chimney from vertical. This is accomplished by us-
ing Vermont Castings Group elbows. Use the 30° Offset
Elbow table on Page 6 to determine proper offset and
parts required.
Each offset requires two (2) elbows. The second elbow is
equipped with support straps. It is very important to install
the second elbow in each offset as close to the ceiling
or support as possible so that the elbow straps can be
secured to framing members to help support the weight
of the chimney.
Determine offset distance of your chimney arrangement
from centerline of replace to centerline of chimney where
it is to pass through ceiling.
Locate center point of the chimney on ceiling as though a
straight up chimney arrangement is to be used. Measure
your offset dimension from straight up chimney center
point on ceiling.
The size of the hole in ceiling will vary with the angle at
which the chimney passes through ceiling.
Drive a nail up through ceiling at marked chimney center
point. Go to oor above and see where hole will be cut.
Check to see where existing ceiling joists and other pos-
sible obstructions are located...i.e. wiring, plumbing etc...
If necessary, reposition chimney and/or replace to avoid
obstructions.
Cover replace collar opening and cut proper sized chim-
ney hole in chimney. The SK8 pipe allows you to run pipe
through a typical 16” on center joist without cutting joists.
Frame the ceiling chimney hole as shown in Figure 12. It is
good practice to use framing lumber that is the same size
as the ceiling joists; this is a requirement at attic level.

Safety strips are not required over noncombustible
oors where all supports at the base of the replace are
noncombustible.
Four (4) nailing anges are incorporated on each corner of
the surround. Bend the nailing anges out, level the box,
then secure it rmly in place by nailing the anges to the
framing members as shown in Figure 15.
The following table gives restop spacer model numbers:
Safety strips are used to ensure that any combustible ma-
terials in front of the replace are protected even though a
noncombustible hearth extension is required.
If replace is to be elevated above the oor, a “Z” shaped
metal safety strip must be fabricated and used to protect
combustible surfaces in front of the replace. This “Z”
shaped safety strip is not provided but must be fabricated
of metal with each horizontal leg at least 1¹⁄₂" (38mm) wide
and equal in length to the metals strips provided with the
replace.
An outside air kit is installed in all SR/SC Series Fireplaces.
If desired, or if local codes mandate the use of an air kit,
then an AK-MST is required to complete the installation
(from air kit to the outdoors). If the outside air kit is to be
used, the AK-MST be installed the re-
place is enclosed. Refer to the AK-MST instructions for
eld installation.
For Canada installations, model CCE-SK Chimney
Collar Enclosure must be used on this replace with Model
SK8 double wall chimney systems.
Start by attaching the rst chimney section to the collar on
top of the replace.
Install the pipe as pictured in Figure 16. When you get
a good lock, you will hear the pipe clearly snap together.
Once sections are snap-locked in place, it is extremely
difcult to get them apart.
When installing elbows, only outer pipe will snap- lock.
Middle pipes simply slide into position. Be sure to always
attach straps on upper elbow to a structural framing mem-
ber. (Fig. 17)
The of the frame the same as
the hole size selected from Figure 13 in order to provide
required the 1¹⁄₂" (38mm) of air space between the outside
diameter of the chimney and the edges of the framed ceil-
ing hole.
Slide replace into position.
Lift the replace front slightly and slide the metal safety
strips under front bottom edge about 1¹⁄₂" (38 mm), allowing
the remainder to extend in front of rebox. Overlap strips
at least 1/2" (13 mm) to provide a positive joint. (Flat safety
strips are packed with replace.) (Fig. 14)

Continue installing the pipe as required until pipe is installed
up through the ceiling. At this point, you must install a
restop spacer.
A restop spacer is used to keep pipe spaced properly and
required for safety.
Nail the restop spacer (at each corner) to the framing
members of the ceiling hole. A restop spacer is
not required at the roof.
Hole sizes listed in Figure 13 for angled restop spacers
provide minimum required air space to chimney pipe for
ceiling thickness up to 8" (203 mm). When combined
thickness of ceiling material, ceiling joists and ooring
material exceeds 8" (203 mm), adjustments must be made
in framing to assure that minimum air spaces to chimney
are maintained.
Figure 18 shows different installation procedures for both
an area that is an attic and an area that is not an attic.
If the area above the ceilingan attic, position the
restop spacer with the ange on the ceiling side and the
angled portion extending up into the hole.
If the area above the ceiling an attic, position the restop
spacer with the ange on the top of the framed hole and
the angled portion extending down into the hole.
Firestop spacers are not available for nor are they required
on vertical walls.
put any sealant around the area where the outer
pipe slides through the restop spacer. If you seal this
area,
In Canada, an attic insulation shield is required to prevent
attic insulation from contacting the chimney section.
If the attic insulation shield is used, the restop is not
required in the attic instal-
lation. Framing dimensions
for the chimney hole should
measure 14¹⁄₂" x 14¹⁄₂" (368
x 368 mm). An attic shield
MUST be installed on top
of attic joists (above the
oor level). (Fig. 19)
In the U.S., it is a
good idea, although not
always required, to install
an attic insulation shield
where blown-in insulation
is planned to be used in
the attic.

Install the attic insulation shield with the anges on its base
extending down into the framing hole. Nail each corner of
attic insulation shield to the framing members of the ceil-
ing hole using 8d nails. Attic shields are not required at
the roof.
Run pipe to rooine. Since the chimney system must be
vented to the out-of-doors, you use an approved
termination.
If a chase is used, refer to the installation manual provided
with the termination cap.
Use same procedure detailed in locating centerpoint of
the ue system.
Drive a nail up through roof at the center point. This will
determine center point on outside of the roof.
Size of roof hole varies with the type of chimney termination
installed. Refer to installation instructions provided with the
chimney termination to nd correct size of roof hole.
There must be a 1¹⁄₂ (38 mm) air space between outermost
portion of chimney sections and any adjacent combustible
surfaces. (Combustible surfaces include burnable materi-
als such as: ceiling members, joists, ooring, combustible
insulation and roof structures.)
Mark an outline of the roof hole around the center of the
point nail. Hole dimensions given in the chimney
top installation instructions are dimensions;
therefore, the hole size must be marked on the roof ac-
cordingly.
Cover the opening of the installed chimney so debris can-
not get into the system.
Cut and frame the hole. It is good practice to use framing
lumber that is the same size as the rafters. Install the frame
securely because the chimney top and ashing anchored
to the frame must be able to withstand heavy winds.
Since you have already preplanned the height of your
termination according to the Ten Foot Rule, continue to
install pipe to the predetermined height.
Check the chimney top installation instructions for details
on how high above the roof top the chimney sections (all
pipes) should extend.

Continue attaching pipe sections to complete system
to next level always being careful that the pipe is rmly
snapped locked in place before proceeding to next pipe
section.
If chimney supports are required, they are installed the
same as elbows. Nail chimney support straps to adjacent
structural framing, as shown on, Page 8, Fig. 9. Bend straps
as necessary and make sure they are secure so they will
support the weight of the chimney. A chimney support is
2¹⁄₂" (64 mm) long when installed. Consider this dimension
when determining how many straight chimney sections
are needed.
Chimney supports are generally used in long runs
in a chase installation.
If you encounter additional ceilings, repeat same steps
required for rst ceiling installation. Refer to restop il-
lustration on Page 12, Figure 18.

Follow the installation instructions provided with the chim-
ney termination you have selected.
Refer to Page 5, Figure 5 for an illustration of a typical
chase installation.
Treatment of restop spacers and construc-
tion of chase may vary with type of building. These
instructions are not a substitute for local building codes.
You check your local building codes to determine
specic requirements for your city or state. Other
building materials may be required in addition to Firestop
Spacers.
All joints between the nished wall and the
replace surround (top/sides) must be sealed with noncom-
bustible material to prevent cold air leakage into the room.
Only noncombustible material may be applied to the facing
of the replace surround. (Black painted area) (Fig. 20)
Finish the wall with material of your choice.
If a combustible material is
used below a at mantel shelf, consult your local building
codes for minimum clearance from top of replace opening
to bottom of mantel shelf.
All joints (top, bottom and sides) where wall or decorative
facing material meets replace surround must be com-
pletely sealed with a noncombustible material. (Figs. 21
and 22)
No side wall protection is required for replaces
installed at 45° to two (2) side walls (corner installation).
Often a decorative surround or vertical portion of the mantel
is desired. If this is constructed of any combustible material
it must be within the safe zone indicated in Figure 23.

Alternate noncombustible materials may be used providing
the (total) thermal resistance (Rt value) of the alternate
material employed is greater than or equal to R = 1.09.
Thermal resistance (R) or thermal conductivity (K), may
be obtained from manufacturer of the material. Factors
are related by the formula K = 1/R.
T = given thickness
R = thermal resistance for a given thickness (T)
K = thermal conductivity
Noncombustible material with a lower R value may be
used, provided thickness of material is sufciently greater
to maintain an equivalent (total) thermal resistance (Rt).

Vermont Castings Group replaces are designed to accept
a 1/2" (13 mm) gas line for installation of an approved
gas appliance. (Vermont Castings Group manufactures
a wide variety of gas logs for use in Vermont Castings
Group replaces.)
Be sure to have the appliance installed in accordance with
building codes.
Gas connection may enter from either left or right side of
the replace.
Locate appropriate gas line in the outer casing of replace
and remove insulation from gas line tube. (Fig. 26)
From inside the replace, locate the knockout on the re-
brick -- be sure you are on the appropriate or "gas line" side
of the replace. Using a at bladed screwdriver or small
chisel and hammer, carefully tap around the knockout until
it loosens and falls out.
Install 1/2" (13 mm) certied gas pipe through opening.
After gas pipe installation is complete, use insulation that
was removed from gas line tube to repack space around
the pipe. Material should be inserted from outside of the
replace and packed tightly to totally seal between the
pipe and tube.
When installing an ANSI Z21.11.2 ventless appli-
ance the nishing material used for the mantel must be
rated at 250°F or greater.
BTU input of a gas appliance installed in replace should
be rated less than 100,000 BTU/Hr.
Gas pipe installation is intended for connection to a deco-
rative gas appliance only when (1.) incorporating an auto-
matic shutoff device and (2.) complying with the Standard
for Decorative Gas Appliances for Installation in Vented
Fireplaces (ANSI Z21.60) CSA draft requirements for
Gas-Fired Log Lighters for Woodburning Fireplaces (Draft
No. 4, August 1993).
Decorative gas appliance should be installed in accordance
with the National Fuel Gas Code, ANSI Z223.1/NFPA 54
(latest edition).
Only unvented gas logsets which have been found to comply with
the Standard for Unvented Room Heaters, ANSI Z21.11.2, are to
be installed in this replace.
