WARNING!
TO PREVENT CONTACT WITH SAGGING OR LOOSE INSULATION, THE FIREPLACE
MUST NOT BE INSTALLED AGAINST VAPOR BARRIERS OR EXPOSED INSULA-
TION. LOCALIZED OVERHEATING COULD OCCUR AND A FIRE COULD RESULT.
2. FRAMING THE FIREPLACE.
Figure 4 shows a typical framing (using 2 x 4 lumber)
of the fireplace, assuming combustible materials are
used. All required clearances to combustibles around
the fireplace must be adhered to. Any framing across
the top of the fireplace must be above the level of the
hemmed edge along the top of the firebox assembly.
Vertical framing at the side of the firebox assembly to
which the side nailing flanges are attached must be
perpendicular to the face of the fireplace and may
have point contact with the side of the fireplace at the
nailing flange. A 1" air clearance must be maintained
at the back and sides of the firebox assembly.
Chimney Sections at any level require a two inch
minimum air space clearance between the framing
and chimney section.

3. HEARTH EXTENSIONS.
A hearth extension must be installed with all fire-
places. It is to protect the combustible floor in front of
the fireplace from both radiant heat and sparks.
A hearth extension of this construction may be cov-
ered with any non-combustible decorative material
and may have a maximum thickness of 6" for the
BW36 and 3” for the BW36C. Seal gaps between the
hearth extension and the front of the fireplace with a
non-combustible sealant.
The construction of and materials used for a factory-
built hearth extension are shown in Figure 5.

than 1 1/2” from the face of the fireplace, can be
placed no closer than 6” from the top and side of the
firebox opening. (See the shaded areas on each
side of the firebox, as defined in Figure 7).
Combustible trim must not cover the black metal sur-
faces of the fireplace. This mantel clearance is in
accordance with Section 7-3.3.3 of ANSI/NFPA 211.
E. CHIMNEY REQUIREMENTS
When planning your fireplace location, the chimney construction and necessary clearances must be considered.
The fireplace system and chimney components have been tested to provide the following flexibility in construc-
tion. The following figures are the minimum distances from the base of the unit.

elbows must never exceed 12 feet in total
length.
To bypass any overhead obstructions, the chimney
may be offset using a 15° offset/return (SL315) or a
30° offset/return (SL330). Perform the following steps
to determine the correct chimney component combi-
nation for your particular installation.
a. Measure how far the chimney needs to be
shifted to enable it to avoid the overhead
obstacle. See Figure 8, dimension “A”.
b. After determining the offset dimension, refer
to Table 1 (page 13) and find the “A” dimen-
sion closest to but not less than the dis-
tance of shift needed for your installation.
An offset and return may be attached together or a
chimney section(s) may be used between an offset
and return. However, the distance between two

a firestop spacer must be installed.
f. The effective height of the firebox assembly
is 335⁄8".
d. Read across the chart and find the number of
chimney sections required and the model num-
ber of those particular chimney parts.
Example: Your “A” dimension from Figure 8 is 141⁄2".
Using Table 1, the dimension closest to but not less
than 141⁄2" is 145⁄8" using a 30° offset/return. It is then
determined from the table that you would need 33"
(Dimension “B”) between the offset and return. The
chimney components that best fit your application are
two [2] SL312’s.

2. CHIMNEY HEIGHT REQUIREMENTS.
(Above the roof line)
BUT
Major building codes specify a minimum chimney height
above the roof top. These specifications are summarized
in what is known as the “Ten Foot Rule”. This rule states:
If the horizontal distance from the side of the chimney to
the peak of the roof is 10 feet or less, the top of the chim-
ney must be at least 2 feet above the peak of the roof, but
never less than 3 feet in overall height above the highest
point where it passes through the roof. See Figure 9.
NEVER LESS
THAN 3 FEET
If the horizontal distance from the side of the chimney to
the peak of the roof is more than 10 feet, a chimney
height reference point is established on the surface of the
roof a distance of 10 feet from the side of the chimney in a
horizontal plane. The top of the chimney must be at least
2 feet above this reference point, but never less than 3
feet in height above the highest point where it passes
through the roof.

These chimney heights are necessary in the interest of
safety and do not ensure smoke-free operation. Trees,
buildings, adjoining roof lines, adverse wind conditions,
etc., may create a need for a taller chimney should smok-

BW36 SERIES WOODBURNING FIREPLACE
No one builds a better fire
F. STEP-BY-STEP INSTALLATION OF THE FIREPLACE SYSTEM
WARNING!
BEFORE STARTING, DO THE FOLLOWING:
1. WEAR GLOVES AND SAFETY GLASSES FOR PROTECTION.
2. KEEP HAND TOOLS IN GOOD CONDITION. SHARPEN CUTTING EDGES AND
MAKE SURE TOOL HANDLES ARE SECURE.
3. ALWAYS MAINTAIN THE MINIMUM AIR SPACE REQUIRED TO THE ENCLOSURE
TO PREVENT FIRE.
STEP 1 - Positioning the Fireplace.
This fireplace may be placed on either a combustible
or non-combustible continuous surface. Follow the
instructions for framing on page 9. Be sure to pro-
vide the minimum 1" air clearance at the sides and
back of the firebox assembly. Framing that is per-
pendicular to the fireplace front may contact the side
of the firebox assembly at the nailing flanges.
STEP 2 - Placing the Protective Metal Hearth
Strips.
Included with your fireplace are two metal hearth
1" OVERLAP
strips measuring approximately 26" x 4". These
strips are used to provide added protection where the
fireplace and hearth extension meet.
UNDER EDGE OF FIREPLACE
METAL STRIPS TWO INCHES
Slide the metal strips two inches under the front edge
of the fireplace with the 2 pieces overlapping other in
the middle of the fireplace to provide continuous cov-
erage of the floor. See Figure 10.
AND HEARTH EXTENSION
Figure 10
Positioning the Metal Strips
STEP 3 - Leveling the Fireplace.
Level the fireplace side-to-side and front-to-back.
Shim with non-combustible material, such as sheet
metal, as necessary.
WARNING!
CAREFULLY FOLLOW THE
INSTRUCTIONS FOR ASSEMBLY
OF THE PIPE AND OTHER PARTS
NEEDED TO INSTALL THIS FIRE-
PLACE SYSTEM. FAILURE TO DO
SO MAY RESULT IN A FIRE, ESPE-
CIALLY IF COMBUSTIBLES ARE
TOO CLOSE TO THE FIREPLACE
OR CHIMNEY AND AIR SPACES
ARE BLOCKED PREVENTING THE
FREE MOVEMENT OF COOLING
AIR.
Important: To ensure proper fit of the glass doors,
check the firebox opening for squareness. Measure
diagonal distances of the opening to make sure they
are equal. If they do not equal, continue to shim the
firebox until those diagonals correspond.
Secure the fireplace by utilizing the nailing tabs locat-
ed on either side of the fireplace to the vertical fram-
ing. Hold-down tabs are provided at the base of the
firebox assembly for attachment to the subfloor if
desired.
NOTE: Top Header may be positioned on the
hemmed seam across the top of the firebox
assembly.

STEP 4 - Assembling Chimney Sections.
No one builds a better fire
Attach either a straight chimney section or an offset to
the top of the fireplace depending on your installation
requirement. When using offsets and returns, we highly
recommend securing in place on the top of the fireplace
with screws to permanently attach them to the top of the
fireplace. See Figure 11.
CAUTION:
INNER FLUE AND OUTER LINER
SECTIONS CANNOT BE DISASSEM-
BLED ONCE LOCKED TOGETHER.
PLAN AHEAD TO INSURE THE
PROPER INSTALLATION HEIGHT IS
ACHIEVED WITH THE SELECTED
CHIMNEY COMPONENTS.
When using elbows right off of the top of the unit, you
will need to flatten the lances before you slip it on the
collar. Once it is on, line it up and secure it with screws
to the unit collar through the slots in the elbow.
These firestop spacers are designed to provide the
minimum two inch air space required around the
chimney. In all situations, the firestop spacers are to
be nailed to the ceiling joists from the bottom or fire-
place side, EXCEPT when the space above is an
insulated ceiling or attic space. In this situation, the
firestop spacer must be nailed from the top side to
prevent loose insulation from falling into the required
two inch air space around the chimney.
Figure 11
Offset Secured to Fireplace
Firestop spacers must be used whenever the chim-
ney penetrates a ceiling/floor area.

Installing the Firestop Spacer
STEP 5 - Preparing the Ceiling for Firestop
Spacers.
STEP 7 - Installing an AS8 insulation shield
Mark and cut out an opening in the ceiling for the par-
ticular firestop spacer being utilized (141⁄2" x 141⁄2" for
an FS338, 141⁄2" x 183⁄4" for an FS339, or 141⁄2" x 23"
for an FS340). Frame the opening with the same
dimension lumber used in the ceiling joists.
An AS8 insulation shield should be installed when
there is a possibility of insulation coming into contact
with the factory-built chimney system. The AS8 is
installed by positioning it over the vertical chimney
section where it penetrates an FS338 firestop spacer.
The FS338 will support the AS8. See Figure 14 on
page 16. When the factory-built chimney penetrates
an insulated ceiling at either 15 or 30 degrees from
vertical, an insulation dam should be constructed from
plywood or sheet metal. A minimum 2" air space
must be provided between the insulation dam and the
factory-built chimney system.
STEP 6 - Installing the Firestop Spacers.
Install the firestop spacer FS338 (Straight), FS339 (if
a 15° offset located is in the ceiling joist area) or
FS340 (if a 30° offset is located in the ceiling joist
area). Nail the four [4] sides of the firestop spacer to
the joists using a minimum of three [3] nails per side.

STEP 10 - Marking the Exit Point of the Roof.
STEP 8 - Double-checking the Chimney Assembly.
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 16.
Continue assembling the chimney sections up through
the firestop spacers as needed. While doing so, be
aware of the height and unsupported chimney length
limitations that are given on page 11 under “Chimney
Requirements”.
Check each section by pulling up slightly from the top
to ensure proper engagement before installing the
succeeding sections. If they have been connected
correctly, they will not disengage when tested.
STEP 9 - Securing the Chimney System.
When offsets and returns are joined to straight pipe
sections, they must be locked into position with the
screws provided, using the predrilled holes. To prevent
gravity from pulling the chimney sections apart, the
returns and the chimney stabilizers have straps for
securing these parts to joists or rafters.
See Figure 15.
NOTE: Be sure to 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.

STEP 11 - Cutting Out the Hole in the Roof.
Measure to either side of the nail and mark the 141⁄2" x
141⁄2" opening required. This is measured on the hori-
zontal; 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. Be sure to maintain a 2" mini-
mum air space between the chimney section and the
roof.

STEP 12 - Assembling the Chimney Sections.
No one builds a better fire
STEP 15 - Completion of the Fireplace Enclosure.
Continue to add chimney sections through the roof
opening, maintaining at least a 2" air space.
Complete the fireplace enclosure, allowing space for out-
side air ducts and gas piping if desired. Electrical wiring
should not come in contact with the unit. A minimum
clearance of 1" must be maintained between the fireplace
sides and the enclosure as well as the fireplace back and
the enclosure. See Figure 4 for framing details.
STEP 13 - Installing Roof Flashing (optional).
If a roof flashing is to be used, install the roof flashing
appropriate to the roof pitch and install a TR344 ter-
minal cap (round) following the instructions shipped
with these accessories.
STEP 16 - Provisions for an Optional Gas Log Set.
Knockouts are provided on both sides of the fireplace to
allow for connection of a certified gas log lighter or a dec-
orative gas appliance with a maximum input of 100,000
BTU/hr. incorporating an automatic gas shutoff device
and complying with the Standard for Decorative Gas
Appliances for Installation in Vented Fireplaces, ANSI
Z21.60. The decorative gas appliance should be
installed in accordance with the National Fuel Gas Code,
ANSI Z223.1-1980. The side refractories are designed to
allow 1/2” black pipe to pass through. Use a non-com-
bustible sealant to seal any opening between the gas
pipe and refractory on the inside. Repack the insulation
removed, to seal around the gas pipe where it exits the
side of the fireplace. A minimum 1-1/2” air clearance
must be provided to the 1/2” black pipe. See Figure 18.
STEP 14 - Installing an Outside Combustion
Air Kit.
The outside air damper assembly is factory installed
on the left hand side of the firebox assembly. While
its use is optional, it is highly recommended to mini-
mize the effects of negative pressure within the
structure. Figure 17 illustrates two of many possible
methods that can be used to supply outside air to the
fireplace system. To complete the outside air system
install the AK22 Outside Air Kit according to the
installation instructions supplied with the compo-
nents.
NOTE: The outside air kit can terminate at
any level with the exception that it
must terminate at least three feet
below the chimney terminal cap as
shown in Figure 17.
This fireplace has been set up for installation of the gas
pipe on the right hand side. If it is necessary to plumb
the unit from the left hand side, remove the gas cover
plate and gas tube from the right hand side of the unit
and install on the left hand side. Cover the hole in the
right hand side outer shell of the fireplace with the cover
plate that covered the gas tube.

Attach the firescreen to the fireplace side, utilizing
the [2] hairpin clips in the columns. Use pliers to
insert the clip through the last strand of screen wire
and into the hole at the midpoint of the fireplace side.
G. CONSTRUCTING A CHASE
A chase is a vertical box-like enclosure built around
the chimney and firebox. A chase may be constructed
for the fireplace and chimney or for the chimney only.
It is most commonly constructed on an outside wall.
STEP 19 - Installing the Glass Doors.
If desired, or required by local building codes, install
the glass doors using the instructions supplied with
the particular set of doors you have chosen.
In cold climates, it is recommended that the chase
floor be insulated using batt type insulation between
the floor joists.
STEP 20 - Positioning the Hearth Extension.
Position and secure the hearth extension over the
protective metal strips that have been placed partially
under the firebox front. See Figure 19. These strips
should be protruding approximately two inches from
under the fireplace front. Seal the crack between the
hearth extension and fireplace with a non-com-
bustible sealant.
Three examples of chase applications are shown in
Figure 20.
STEP 21 - Applying Finishing Materials on the
Hearth Extension.
Apply the non-combustible finishing material of your
choice to the hearth extension. Do not install com-
bustible materials over the black face of the fire-
place This poses a safety hazard and may start a
structure fire. You may only use non-combustible
material over the black face of the fireplace. Refer to
Figure 7 for combustible material information.

No one builds a better fire
WARNING!
The chase is constructed using framing mate-
rials much the same as the walls in your
home. A variety of materials may be used
including brick, stone, veneer brick, or stan-
dard siding materials.
DETAIL INSTRUCTIONS FOR INSTALLA-
TION OF THE CHASE TOP, STORM COL-
LAR AND TERMINAL CAP ARE PACKAGED
WITH THESE PARTS. TO AVOID DANGER
OF FIRE, ALL INSTRUCTIONS MUST BE
STRICTLY FOLLOWED, INCLUDING THE
PROVISION OF AIR SPACE CLEARANCE
BETWEEN CHIMNEY SYSTEM AND ENCLO-
SURE. TO PROTECT AGAINST AGAINST
THE EFFECTS OF CORROSION ON THOSE
PARTS EXPOSED TO THE WEATHER, WE
RECOMMEND THAT THE CHASE TOP AND
TERMINAL CAP BE PAINTED WITH A RUST
RESISTANT PAINT.
In constructing the chase, several factors
must be considered.
a. Maintain a 1" minimum air space around
the firebox.
b. Maintain a 2" air space around the chim-
ney.
c. The chase top must be constructed of a
non-combustible material.
2. Installing a Terminal Cap on a Chase Enclosed
Chimney.
d. In cold climates a firestop spacer should
be installed in an insulated false ceiling
at the 8 foot level above the firebox
assembly. This prevents heat loss
through the fireplace.
Construct a chase of desired materials maintaining a mini-
mum 2" air space around the chimney.
WARNING!
e. In cold climates, the walls of the chase
should be insulated to the level of the
false ceiling as shown in Figure 21. This
will help prevent heat loss from the home
around and through the fireplace.
NEVER INSTALL A SINGLE WALL SLIP SECTION OR
SMOKE-PIPE IN A CHASE STRUCTURE. THE HIGH-
ER TEMPERATURE OF THIS SINGLE WALL PIPE
MAY RADIATE SUFFICIENT HEAT TO COM-
BUSTIBLE CHASE MATERIALS TO CAUSE A FIRE.
Install the chimney sections up through the chase
enclosure. When using a round terminal cap
(TR344), the last section of pipe must extend above
the top of the chase cone to allow installation of the
storm collar and terminal cap.
ROUND TERMINAL CAP
(TR342, TR344)
METAL CHASE TOP
A telescoping round terminal cap (TR342) is provided
to simplify the installation of the terminal cap on a

STARTING THE FIRE. Check the flue damper to be
certain it is in the full open position. Place crumpled
or twisted paper under the fireplace grate. Loosely
arrange kindling or small pieces of wood to form a
layer above the paper. Light the paper and add small
pieces of wood until a hot bed of embers has been
established. At this point add progressively larger
pieces of wood until you are able to position 4” diame-
ter split logs as shown in Figure 23.
Use only a solid wood fuel or a listed Heat-N-Glo gas
log set. Do not use a fireplace insert or products not
specifically tested and listed for use in this fireplace.
Use common sense when burning this fireplace. The
fire must be built on the fireplace grate, without dan-
ger of the burning fuel falling out of the firebox.
CAUTION:
When first lighting your fireplace, it may be necessary
to pre-warm the flue to establish a draft. This is done
by holding a rolled up piece of burning newspaper
under the flue damper for a few moments. This will
prevent smoke spillage during start-up.
NEVER USE GASOLINE, GASO-
LINE-TYPE LANTERN FUEL,
KEROSENE, CHARCOAL LIGHTER
FLUID, OR SIMILAR LIQUIDS TO
START OR ‘FRESHEN UP’ A FIRE
IN THIS FIREPLACE. KEEP ALL
SUCH LIQUIDS WELL AWAY FROM
THE FIREPLACE WHILE IT IS IN
USE TO AVOID THE RISK OF A
HOSTILE FIRE.

tainer of ashes should be placed on a non-combustible
floor or on the ground, well away from all combustible
materials, pending final disposal. If the ashes are dis-
posed of by burial in soil or otherwise locally dis-
persed, they should be retained in the closed contain-
er until all embers have thoroughly cooled.

Firewood should be seasoned for at least 6 months
before it can be burned as a fireplace fuel.
Improperly seasoned (green or wet) wood will cause
the fireplace to smoke, will allow creosote deposits
to rapidly build-up in the chimney system and may
cause roof stains to develop.
Fuel products with abnormal burning characteristics,
including synthetic logs that contain wax binders,
scrap lumber, wax or plastic coated cardboard and
other highly volatile fuels that burn at excessive tem-
peratures, may cause the fireplace to operate in an
unsafe manner. Flammable liquid fuel are explosive
and must never be used to start or freshen a fire.
Heat-N-Glo does not warrant the structural or func-
tional performance of the fireplace system when
such synthetic fuels or flammable liquids have been
used.
GLASS DOORS. Most efficient fireplace operation
using glass doors is with the doors open. When the
doors are open, the screen must be closed. Only
Hearth Technologies Inc. (HTI) glass doors, model
numbers DM1036, DM1036A and DM1036B may
be used on the BW36 Series fireplaces.

BW36 SERIES WOODBURNING FIREPLACE
No one builds a better fire
Before starting a fire in your BW36 Series fireplace,
use the following check list:
WARNING!
FIREPLACES EQUIPPED WITH
DOORS SHOULD BE OPERATED
ONLY WITH DOORS FULLY OPEN
OR FULLY CLOSED. IF DOORS
ARE LEFT PARTIALLY OPEN, GAS
AND FLAME MAY BE DRAWN OUT
OF THE FIREPLACE OPENING,
CREATING THE RISK OF BOTH
FIRE AND SMOKE.
FLUE DAMPER. The flue damper is operated by
moving a handle located in the fire chamber, which
should place the damper in a fully open position.
Pull the handle down to open, push the handle up to
close. Verify this by looking up from the inside of
the firebox. Always operate this fireplace with the
damper fully open. Please note: down drafts,
obstructions, damage or poor (wet) fuels can cause
smoke spillage.
CHIMNEY INSPECTION. Visually inspect the chim-
ney internally for obstructions and construction dam-
age. Flue pipe joints and seams must be continu-
ous and mechanically tight. In a used chimney,
additional inspection is needed for creosote build-up
which is the formation of a flammable sediment.
When wood is burned slowly, it produces tar and
other organic vapors, which combine with expelled
moisture to form creosote. The creosote vapors
condense in the relatively cool chimney flue of a
slow-burning fire. As a result, creosote residue
accumulates on the flue lining. When ignited, this
creosote makes an extremely hot fire.
WARNING!
CONTINUED OVER-FIRING CAN
PERMANENTLY DAMAGE YOUR
FIREPLACE SYSTEM. EXAMPLES
OF OVER-FIRING ARE:
The chimney should be inspected at least twice a
year during the heating season to determine if cre-
osote build-up has occurred.
If creosote has accumulated, it should be removed
to reduce the risk of a chimney fire.
1. THE “NORMAL LOG FIRE”
SHOULD BE CONTAINED IN THE
GRATE, WITH THE LENGTH OF
LOGS NO GREATER THAN THE
BACK WALL OF THE FIREPLACE.
CHIMNEY CLEANING. If you do detect a build-up
of creosote, contact a qualified chimney sweep or
clean it yourself. To do this, perform the following
steps:
2. THE FOLLOWING MATERIALS
MUST NOT BE USED IN THIS FIRE-
PLACE: QUANTITIES OF SCRAP
LUMBER, PINE BRANCHES,
PROCESSED FIRE LOGS AND FIRE
STARTERS, OR CARDBOARD
BOXES WHICH EXCEED THE VOL-
UME OF THE “NORMAL LOG
FIRE”. THESE MATERIALS PRO-
DUCE MANY SPARKS AND MUST
NOT BE USED.
1. Open the damper.
2. Hang a damp sheet across the fireplace
opening to stop dirt and soot from entering
the room.
3. Remove the Terminal Cap or Housing
Top. See Figure 25.
4. Clean with a stiff nylon brush attached to a
pole OR tie a rope to a burlap bag filled
with straw and several small stones or
sand. Work up and down the flue until
clean.
5. Replace the terminal cap or housing top.

AND BUYER PROTECTION PLAN.
CLEAR SPACE NEAR FIREPLACE. The hearth
extension must extend at least 16 inches to the front
and 8” to the sides of the firebox opening for the
BW36 Series fireplace. Combustible materials must
not be stored in this area. Combustible walls perpen-
dicular to the front of the fireplace must be at least 12
inches from the fireplace opening. Room furnishings
such as drapes, curtains, chairs, or other com-
bustibles must be at least 4 feet from the open front of
the fireplace.
NEGATIVE AIR PRESSURE WITHIN THE STRUC-
TURE. This fireplace will operate correctly only if
adequate ventilation is provided to allow proper draft
to the fireplace system. Heat-N-Glo assumes no
responsibility for the improper performance of the
fireplace system caused by inadequate draft due to
environmental conditions, downdrafts, tight sealing
construction of the structure, or mechanical exhaust-
ing devices which create a negative air pressure with-
in the structure where the fireplace is located.
GRATE. The factory installed integral grate must be
used to hold the logs from falling out of an open fire-
place and to allow air to pass between the burning
logs. It is important to keep the fire off the hearth
and to allow the ashes to collect beneath the fire,
thereby forming a layer of additional heat protection.
See Figure 23, page 21. Use only model number
GR16 integral grate for replacement.
OUTSIDE AIR. A damper control handle allows the
individual control of the outside air inlets if your fire-
place is equipped with this option. Use of outside air
for combustion is highly recommended to conserve
