Planning Information
Preplanning an installation is very important to ensure
safety and to save time and money. An installer must
predetermine where a fireplace will be set and how the
chimney system will be run.
Mounting the Fireplace
A fireplace may only be mounted on the following surfaces:
1. A flat 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 fireplace.
The fireplace
must be spaced 1” (25mm) from a com-
bustible back wall and 1/2” (13mm) from a combustible
side wall or support. (Page 13, Fig. 17)
Planning the Chimney Run
The Ten Foot Rule
Major U.S. building codes specify a minimum chimney
height above the roof top. The “Ten Foot Rule” is a fire
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. 5)
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’ (3m) or less, the top of the
chimney must be at least 2’ (610mm) above the peak
of the roof, but never less than 3’ (914mm) 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’ (3m), a chimney height
reference point is established on the surface of the
roof a distance of 10’ (3m) from the chimney in a
horizontal plane. The top of the chimney must be
at least 2’ (610mm) above the reference point, but
never less than 3’ (914mm) in height above the highest point where it passes through the roof.
FP288a
Fig. 4 Installed lengths of chimney sections.
Determine how the chimney will be run, length of run
and chimney components required to complete the
job. (Fig. 4) Never 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’ (6m).
5. No more than 2 offsets (4 total 30° elbows in U.S./or
2 total 45° elbows in Canada) per fireplace may be
used.
6. A guy wire stabilizer is required for chimneys extending more than 6’ (1.8m) above a roof line.

BFC36 Balance Flue Heat-Circulating Fireplace
Chimney Supports
The chimney system is supported by the fireplace for
vertical chimney heights less than 30’ (9m) above the
hearth. Chimney supports are required if the vertical
height exceeds 30’ (9m). Locate chimney supports
at ceiling holes or other structural framing at 30’ (9m)
heights. Spacing between chimney supports must not
exceed 30’ (9m). Use Chimney Support Model TCS8A.
(NOTE: The TCS8A cannot be mounted directly to
the fireplace.) Support provided by elbow straps fulfills
the support requirement only if they are spaced as previously described. (A chimney support is 2¹⁄₂" (64mm)
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. 6)

Installation
Insulating Fireplace Enclosure
for Cold Climates
If you live in a cold climate, it is not required but
highly recommended that you insulate fireplace
enclosure to eliminate cold air penetration as much
as possible.
Insulate base of fireplace with a noncombustible
insulation rated for a minimum of 300°F. Insulating
is very important for outside wall installations over
a concrete slab. If fireplace is installed on a platform,
insulation should be placed on top of the platform
before fireplace is set. (Fig. 7)
When a fireplace is installed in a chase or on a
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 firestop at
the first ceiling level above the fireplace and enclose
the chase with sheeting material. Insulation may
then be installed above sheeting material to assure
the space around the fireplace is totally protected.
(Fig. 2)
When installing the chimney, DO NOT caulk between outer pipe and firestop. It is vital that some air
be allowed to flow through this very thin gap.
CAUTION: When installing a fireplace in an insulated enclosure, be sure all required air spaces
are maintained. (Page 13, Fig. 17)
Chase Installation
A chase is a vertical box-like structure which encloses
the fireplace and/or chimney. Chases are typically built
on the outside of the house with fireplace opening cut
into the outer wall of a room. (Page 4, Fig. 2)
If you need help in determining fireplace location or how
the chimney system should be run, contact your Ver
mont Castings, Majestic Products dealer for assistance.

Framing
Framing can be constructed before or after the fireplace
is set in place, however, most installers build the frame
before setting the fireplace.
Frame fireplace with 2 x 4 lumber or heavier materi
als. Refer to framing dimensions in Figure 1 for basic
fireplace specifications.
NOTE: Framing should be positioned to accommodate
wall covering and fireplace facing material.
Installing Electrical Wire
The fan requires 120VAC, 60 Hz power which may be
connected to the right side of the fireplace using the
romex pigtail provided with teh unit. This power must
be completed before the fireplace is secured and finish
material applied.
1. Attach the white wire from house power to the white
wire of the romex pigtail and secure with a wire nut.
2. Attach the black wire from the house power to the
black wire of the romex pigtail and secure with a
wire nut.
3. Attach the ground wire from house power to the
ground wire of the romex pigtail and secure with a
wire nut. (Fig. 8)
IMPORTANT: The wire nuts must be tight.

Chimney Set-up
Since you have already preplanned the chimney run,
you should know exactly how the installation is to
be accomplished — how much pipe is required, the
number of elbows, if any, and type of termination to be
used.
CAUTION: REPORT TO YOUR DEALERS ANY
PARTS DAMAGED IN SHIPMENT, SPECIFICALLY
CHECK THE END CONNECTION OF CHIMNEY SECTIONS AND ELBOWS.
NOTE: The BFC36 fireplace must use CFM Corporation Model triple wall 8” chimney components only. The
installation procedure described in this manual applies
only to this system.
Straight-Up Chimney Installation
To mark the centerline of the flue, put the fireplace
in final position and measure out from the wall: 8³⁄₄"
(222mm). Mark a spot on the ceiling directly above the
fireplace. Draw a line parallel to the back wall through
this mark. (Fig. 9)
Using a plumb bob positioned directly over center point
of fireplace flue collar, mark the ceiling to establish the
chimney center point. (Fig. 9)

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 floor above and see where hole will be
cut. Check to see where existing ceiling joists and other
possible obstructions are located...i.e. wiring, plumbing
etc... If necessary, re-position chimney and/or fireplace
to avoid obstructions.
Cutting the Hole
Cover fireplace collar opening and cut proper sized
chimney hole in chimney.
Framing the Ceiling Hole
Frame the ceiling chimney hole as shown in Figure
10. It is good practice to use framing lumber that is the
same size as the ceiling joists; this is a requirement at
attic level.

Offset Installation
In order to clear an obstruction, it may be necessary to
offset chimney from vertical. This is accomplished by
using elbows. Use the 30° Offset Elbow table on Page
5 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 fireplace 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.

Positioning, Safety Strips,
Securing the Fireplace
Slide fireplace into position.
Lift the fireplace front slightly and slide the metal safety
strips under front bottom edge about 1¹⁄₂” (38mm), allowing the remainder to extend in front of firebox. Overlap strips at least 1/2” (13mm) to provide a positive joint.
(Flat safety strips are packed with fireplace.) (Fig. 12)
Safety strips are used to ensure that any combustible
materials in front of the fireplace are protected even
though a non-combustible hearth extension is required.
If fireplace is to be elevated above the floor, a “Z”
shaped metal safety strip must be fabricated and used
to protect combustible surfaces in front of the fireplace.
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 fireplace.
NOTE: Safety strips are not required over non-combustible floors where all supports at the base of the
fireplace are noncombustible.
Four (4) nailing flanges are supplied with the fireplace
(found on the fireplace hearth). To level the box and
secure it firmly in place, remove the nailing flanges from
the hearth and install at the sides of the fireplace as
shown in Figure 13.

Installing the
Chimney System
Start by attaching the first chimney section to the collar
on top of the fireplace.
Install the pipe as pictured in Figure 14. When you
get a good lock, you will hear the pipe clearly snap
together. Once sections are snap-locked in place, it is
extremely difficult to get them apart. Make sure the
pipe is firmly snapped and locked together as each
pipe section is mounted.
When installing elbows, only outer pipe will snaplock. Middle pipes simply slide into position. Be sure
to always attach straps on upper elbow to a structural
framing member. (Fig. 15)
Continue installing the pipe as required until pipe is
installed up through the ceiling. At this point, you must
install a firestop spacer.
Installing the Firestop Spacer
in the Ceiling Hole
A firestop spacer is used to keep pipe spaced properly
and required for safety.
Nail the firestop spacer (at each corner) to the framing
members of the ceiling hole. NOTE: A firestop spacer
is not required at the roof.
Hole sizes listed in Figure 11 for angled firestop spacers provide minimum required air space to chimney
pipe for ceiling thickness up to 8” (203mm). When
combined thickness of ceiling material, ceiling joists
and flooring material exceeds 8” (203mm), adjustments
must be made in framing to assure that minimum air
spaces to chimney are maintained.

DO NOT put any sealant around the area where the
outer pipe slides through the firestop spacer. If you
seal this area, it may cause a fire hazard.
Canadian Requirements
for Insulation Shield
In Canada, an attic insulation shield is required to prevent attic insulation from contacting the chimney section. Framing dimensions for the chimney hole should
measure 17¹⁄₂” x 17¹⁄₂” (445 x 445mm). An attic shield
MUST be installed on top of attic joists (above the floor
level). (Fig. 17)

Continue Installing Pipe to Complete Run
Continue attaching pipe sections to complete system
to next level always being careful that the pipe is firmly
snap-locked in place before proceeding to next pipe
section.
Chimney Supports
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, Figure
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" (64mm) long when installed.
Consider this dimension when determining how many
straight chimney sections are needed.
NOTE: Chimney supports are generally used in long
runs in a chase installation.
Additional Ceilings
If you encounter additional ceilings, repeat same steps
required for first ceiling installation. See firestop illus-
tration in Page 11, Figure 16.
Penetrating the Roof
Run pipe to roofline. Since chimney system must be
vented to the out-of-doors, you must use an approved
CFM Corporation termination.
If a chase is used, refer to the installation manual provided with the termination cap.
Locate Chimney Centerpoint On Roof
Use same procedure detailed in locating center point of
the flue system.
Drive a nail up through roof at the center point. This will
determine center point on outside of the roof.
Cut and Frame Roof Hole
Size of roof hole varies with the type of chimney termination installed. Refer to installation instructions provided with CFM Corporation chimney termination to find
correct size of roof hole.
There must be a 1¹⁄₂” (38mm) air space between outermost portion of chimney sections and any adjacent
combustible surfaces. (Combustible surfaces include
burnable materials such as: ceiling members, joists,
flooring, combustible insulation and roof structures.)
WARNING: Do not pack required air spaces with
insulation or other materials.
Mark an outline of the roof hole around the center of the
point nail. NOTE: Hole dimensions given in the chimney top installation instructions are horizontal dimensions; therefore, the hole size must be marked on the
roof accordingly.
Cover the opening of the installed chimney so debris
cannot 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 flashing anchored to the frame must be able to withstand
heavy winds.
Install Remainder of Chimney Sections
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 sec-
tions (all pipes) should extend.

Installing Chimney in a Chase
Refer to Page 4, Figure 2 for an illustration of a typical
chase installation.
CAUTION: Treatment of firestop spacers and construction of chase may vary with type of building. These
instructions are not a substitute for local building codes.
You must check your local building codes to determine
specific requirements for your city or state. NOTE:
Other building materials may be required in addition to
firestop spacers.
CAUTION: All joints between the finished wall and the
fireplace surround (top/sides) must be sealed with noncombustible material to prevent cold air leakage into
the room. Only noncombustible material may be applied
to the facing of the fireplace surround. (Black painted
area) (Fig. 18)
Finish the wall with material of your choice. Do not
install a combustible mantel shelf less than 12”
(305mm) above the grille opening. Do not install a
mantel face plate less than 6” (159mm) from top of
grille opening. (Fig. 20) If a combustible material is
used below a flat mantel shelf, consult your local building codes for minimum clearance from top of fireplace
opening to bottom of mantel shelf.
All joints (top, bottom and sides) where wall or decorative facing material meets fireplace surround must
be completely sealed with a noncombustible material.
(Figures 19 and 20)
NOTE: No side wall protection is required for fireplaces
installed at 45° to two (2) side walls (corner installation).

Installing Line for Gas Logs
CFM Specialty Home Products fireplaces are designed
to accept a 1/2” (13mm) gas line for installation of an
approved gas appliance. (CFM Specialty Home Products manufactures a wide variety of gas logs for use in
CFM Specialty Home Products fireplaces.)
Be sure to have the appliance installed in accordance
with building codes.
Gas connection may enter from either left or right side
of the fireplace.
Locate appropriate gas line in the outer casing of fireplace and remove insulation from gas line tube. (Fig.
26)
From inside the fireplace, locate the knockout on the
firebrick -- be sure you are on the appropriate or “gas
line” side of the fireplace. Using a flat bladed screwdriver or small chisel and hammer, carefully tap around
the knockout until it loosens and falls out.
Install 1/2” (13mm) certified 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 fireplace and packed tightly to totally seal
between the pipe and tube.
Note: Gas pipe should not come in contact with
any wood structures until it has reached a point at
least 1” (25mm) away from fireplace side.
BTU input of a gas appliance installed in fireplace
should be rated less than 100,000 BTU/Hr.
Gas pipe installation is intended for connection to a
decorative gas appliance only when (1.) incorporating
an automatic shutoff device and (2.) complying with the
Standard for Decorative Gas Appliances for Installation in Vented Fireplaces (ANSI Z21.60) or 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).
CAUTION: When using decorative gas
appliance, flue damper must be set in fully
open position. Glass doors on the fireplace
must also be fully opened.
WARNING: Do not operate an unvented gas
log set in this fireplace with the chimney
removed.
WARNING: When installing an unvented
gas log set, the model AH3244BK or
AH3244PB 4” adjustable hood must be
used.
