EPA WOOD-BURNING FIREPLACE
PROGRAM QUALIFIED
This appliance has met the U.S. Environmental
Protection Agency (EPA) Low Mass Wood-
burning Fireplace Program Phase 2 emission
level (g/kg), as per test protocol ASTM 2558
"standard test method for determining particu-
late matter emissions from fires in low mass
wood-burning fireplaces".
Fresh FireTM
Burn System
1- Air is diverted under the front of the grate,
gaining heatfromtheemberandashmaterial
for more efficient combustion.
2- Cool air is deflected to prevent cooling
of the fire, so that high temperatures are
maintained.
3- Efficient combustion leads to lower emis-
sions,becausethehighertemperatures burn
up more volatile gasses and particulates.
4- Exhaust air is effectively pulled into the
chimney, and heat from the fire is circulated
into the living space.

Building A Fire
(starting and maintaining a fire)
To start a fire, place several crumpled up balls
of newspaper in the firebox. Place small dry
pieces of kindling on top of the paper, criss-
crossingthekindlingsothatthereare airspaces
in between. Keep the fuel far back enough
so that air can get underneath. Open the air
controls fully and light the newspaper. Once
the newspaper and the kindling is well ignited,
close the firescreens. Once the kindling fire is
well established, cord wood can be added (see
How To Use The Outside Air Register section for
proper operation of the air controls).
The unit will burn best with 2-3 pieces of cord
wood spaced 1/2 to 1 inch apart and allowing
air to get under the fuel. Criss-crossing or ar-
ranging the fuel so that air can get underneath,
will help the fire to get started easily. The unit
should be operatedwiththeaircontrolfullyopen
long enough to get the cord wood well ignited.
For the Fresh FireTM system to burn efficiently,
air must flow through the bottom of the grate
and up in between the logs. Do not let ashes
stack up to a height which will obstruct the
opening between the base of the firebox and
the bottom of the log retainer.
OPERATING THE FIREPLACE
Fuel
USE SOLID NATURAL WOOD FUEL ONLY.
The HE43-2 fireplace is designed to work best
when fueled with seasoned natural wood only.
Hardwoods are preferredto softwoodssincethe
energy content of wood is relative to its density.
Hardwoods will result in a longer burning fire
and less frequent refueling. A moisture content
of 15% to 20% (seasoned) is recommended.
Wood that has been cut and split and let to
dry under a cover for a period of one year will
usually meet that criteria. The required drying
time will vary depending on the climate. Wood
that is packed tight together will take longer to
dry. Seasoned wood is darker in color than wet
wood and will have visible cracks in the grain
on the ends. Excessively wet wood will be dif-
ficult to burn and will result in lower efficiency,
increased creosoting and deposits on the glass
and in the chimney. Excessively dry wood will
burn well but will also have higher emissions
and shorter burning time.
Do not burn scrap or garbage, treated wood or
wood such as driftwood from the ocean which
has been exposed to salt or other chemicals.
Salt or chemicals can corrode the firebox and
chimney. Do not burn large amounts of paper,
cardboard,Christmas tree branchesor building
constructionmaterials. Intensefiringwiththese
materials may overheat the fireplace, causing
damage to the unit, a fire or even possibly ignit-
ing a chimney fire if the chimney is creosoted.
Burningunapprovedfuel,resultingin excessive
pollutantsbeingemitted,may be prohibitedand
subjectto afine orother penalty by the authority
having jurisdiction in your area.
Processed firelogs can be used. Refer to firelog
warnings and caution markings on the packag-
ing prior to use.
First Fires
Before using the fireplace make sure to
remove the plastic wrapping on plated door.
Remove any glue residue left by the label
using mild soap.
The first five or six fires should be small fires of
short duration (about 30 to 60 minutes). This
will help cure the refractory bricks. During the
first few fires of this appliance there may be
some odor and smoke due to the curing of the
paint, dust accumulation and burning off of
lubricants used in the manufacturing process.
It may set off a smoke alarm located in the same
room. For this reason the room should be well
ventilated for the first few fires.

D. Wet wood
Wetor tarredwoodwillsmoulderandsmoke
instead of burning properly. Your dealer can
help you determine if you have properly
seasoned wood for burning.
E. Dirty or blocked chimney
Check to make sure the chimney is clear and
clean. If dirty call a certified chimney sweep
or use a properly sized chimney brush to
clean.
F. Chimney not long enough
The minimum chimney height is twelve (12)
feet(3.7m)notincludingthefireplaceheight.
The chimney must extend at least three (3)
feet (915 mm) above its point of contact
with the roof and at least two (2) feet (610
mm) higher than any roof or wall within ten
(10) feet (3 m) of it. When installed with
one offset, the minimum chimney height
is fifteen (15) feet. Additional height will
increase draftandwilldecreasethe tendency
to smoke.
G. Poor chimney draft
With no fire, there should be sufficient draft
to exhaust cigarette smoke introduced under
the chimney. Chimneys installed against an
outside wall without protection may generate
back draft problems which will cause start-up
problems. To prevent this, open a nearby
window, roll up a piece of paper and light it.
Then, hold it in the upper part of the firebox
to warm up the chimney. Wait until the draft
is sufficient, then start the fire.
IMPORTANT CAUTIONS
A. Donotblockthehotairvents tothefireplace
as this will cause the fireplace to overheat.
B. Never use gasoline, gasoline-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.
C. Do not burn coal. The sulphur in coal will
corrode the firebox and chimney.
D. Keep combustible materials at least 48”
(1.2 m) away from the front of the fireplace
opening.
E. Never leave children unattended when
there is a fire burning in the fireplace.
F. Do not use the HE43-2 as an incinerator
to burn paper, cardboard or construction
material such as pressed wood, plywood
or lumber. Use only untreated wood. Wood
protectors, metallic paper, coal, plastic,
waste, beach wood, Christmas tree, sul-
phur and/or oil will damage the fireplace.
G. Donotburndriftwood whichhasbeenin the
ocean or salt water. The salt will corrode
the firebox and chimney.
H. Do not burn wood in the area in front of
the log retainer.
I. Do not allow the wood to smoulder or burn
without flame, since this will produce
excessive creosote in the unit as well as
increased particulate emissions.

HOWTOUSETHEOUTSIDEAIRREGISTER
(FIREPLACE)
The outside air register is located on the up-
per left part of the top louver. The outside air
register supplies oxygen to the fire and allows
control of the fire when the doors are closed.
The fresh air must come from outside the house
(the air intake must not draw air from inside the
house). This will minimize negative pressure in
the house. The more you slide the register to
the left, the more fresh air into the firebox and
the more accelerated combustion you will get
(see Figure 1). When starting a fire, the register
should always be fully opened.
Forinformationonwhenyoushouldstartclosing
the register, see "Refueling" section.
REFUELING
The HE43-2 fireplace will operate best if at-
tention is given to operating the unit with the
outside air register fully opened (see Figure
1)after refueling in order to bring the firebox
and the chimney system up to their optimum
operating temperature. Combustion efficiency
is relative to firebox temperature. To obtain this
temperature, the fireplace must be operated
with the primary air fully opened during 10 to
20 minutes after reloading, depending on the
heat and on the moisture content of the wood.
Onceyouhavereached the desiredtemperature,
the outside air register control can be set to a
medium setting. The benefit of this technique
will be cleaner glass, less creosoting, greater
efficiency and the most pleasing fire for your
enjoyment.
Settheairregistertothefullopenpositionbefore
opening the doors to reduce the possibility of
smoke entering the home from the fireplace.
CLOSING THE DOORS
As soon as a layer of embers covers the surface
under the log retainer, it is possible to close
the doors with the outside air register opened.
Closing the doors prematurely may result in:
• Thereboxllingwithsmoke;
• Theameintensitycutsdownexcessively.
Meaning the fireplace is not hot enough to
close the doors.
SMOKING –
CAUSES AND TROUBLESHOOTING
To reduce the likelihood of smoking when
opening the door, set the outside air register to
the left before opening the door. Your fireplace
has been designed and tested to provide smoke
free operation. Occasionally, there may be a
small amount of smoking upon lighting the fire,
until the chimney heats up but this should not
continue. If the fireplace continues to smoke
it is probably for one of the following reasons:
A. The doors are partially opened
When you open the doors, open them
completely.
B. Negative pressure in the house
As the fire burns, air goes up the chimney.
This air must be replaced through leakage
into the house or through the outside air
duct. When operating the HE43-2 fireplace,
open a nearby window temporarily to check
if there is adequate replacement air supply.
C. Fans operating (e.g.: range hood)
Fans such as range hoods or bath fans draw
air out of the house and may actually cause
a negative pressure in the house. Turn off all
fansandopena nearbywindowtodetermine
if this is the cause of the problem.

Caution: It is necessary to remove the
baffle from the top of the firebox before
cleaning the chimney.
Dealing With a Chimney Fire
Regular chimney maintenance and inspection
canpreventchimneyfires. Ifyouhaveachimney
fire, follow these steps:
1. Close the fireplace glass doors and the air
inlet.
2. Close the chimney outside air register.
3. Alert your family of the possible danger.
4. If you require assistance, alert your fire
department.
5. If possible, use a dry chemical fire extin-
guisher, baking soda or sand to control
the fire. Do not use water as it may cause
dangerous steam explosions.
6. Watch for smouldering or fire on combus-
tibles next to the fireplace and chimney.
Check outside to ensure that sparks and
hot embers coming out of the chimney are
not igniting the roof.
7. Do not use the fireplace again until your
chimney and fireplace have been inspected
byaqualifiedchimneysweeporafiredepart-
ment inspector.
Top Baffle Removal Prior to Cleaning The
Chimney
Before starting to clean your chimney, we
recommend that you remove the top baffle to
avoid creosote dust collection at the top of the
baffle. Follow these steps to set the top baffle
out of the way:
1. Remove the baffle refractory and it’s iron
anglesupport(gure2);
2. Obstruct the dilution air box inlet, located in
the upper back of the firebox, with a metal
orcardboardsheet;
3.Closethechimneydamperanddoors;
4.Proceedwithchimneysweep;
5. Open the chimney damper before opening

6.Cleanouttherebox;
7. REMOVE the metal or cardboard sheet,
placed in step #2, and re-install the baffle
and it’s iron angle support.
MAINTAINING YOUR FIREPLACE
Creosote - Formation and Need for Removal
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.
The chimney shall be inspected at least twice
a year during the heating season to determine
when a creosote buildup has occurred.
When creosote has accumulated it shall be
removed to reduce the risk of a chimney fire.
When the creosote accumulation is large, a
creosote fire in the chimney can damage the
chimney and overheat the surrounding wood
framing. Creosote formation in a chimney can
be minimized by making sure there is always
visible flame burning, avoid smouldering fires
and by proper refuelling techniques.
Chimney Maintenance
Regular chimney inspection and maintenance
combinedwithproperoperationwillhelpprevent
chimney fires. Keep your chimney clean. Do
not allow more than a 1/16" (1.6mm) build-up
of creosote in your chimney. The amount
of creosote will depend on variables such as
frequency of use and type of fire. We recom-
mend that you:
A. Initially, inspect the chimney system weekly.
By doing this, you will learn how often it will
be necessary to clean your chimney.
B. Have your chimney cleaned by a qualified
chimney sweep. If you wish to clean it
yourself, we recommend using a stiff plastic
or non-metallic brush. If a metal brush is
used, its size should be slightly smaller than
the flue to avoid damaging the chimney. Do
not use a brush that will scratch the stainless
steel interior of the chimney.
C. Do not expectchemicalcleaners to keepyour
chimney clean. The raincap can be removed
forinspectionand/orcleaningofthechimney.
Unscrew the braces which attach the raincap
to the chimney. Using gloves, firmly grip the
upper portion of the rain cap. Turn the cap
and lift it off the chimney.

WARNING
Disposal of Ashes: Ashes should
be placed in a metal container
with a tight fitting lid. The closed
container 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 disposed of by burial
in soil or otherwise locally dis-
persed, they should be retained
in the closed container until all
cinders have thoroughly cooled.
Door Frame Care
Use a glass cleaner and a soft cloth to polish
the frame. Do not use abrasives such as steel
wool or steel pads for they may scratch the
door frame finish.
Disposing Of Ashes
Remove ashes only when the fire is out and
the ashes are cold (24 to 48 hours after the
fire is out).
Ashes removal must be –performed regularly
during theoperatingseason. An excessofashes
will block the airflow and risks to increase the
particle emissions. In order to burn efficiently,
do not let ashes stack up to a height which will
obstruct the opening between the base of the
firebox and the bottom rod of the log retainer.
Rotatethelogretainer on thebackrefractoryand
remove the ashes. Make sure the log retainer
is properly leaning on the back refractory, in
case it’s rotation is obstructed.
Do not leave the ashes in the house as they give
off carbon monoxide and other toxic gases.

REFRACTORY REPLACEMENT
The intense heat of the fire will normally cause
hairline cracks in the refractory. These cracks
canbe minimizedbypropercuring as described
in “First Fires”. They will not normally dimin-
ish the effectiveness of the refractory. If large
cracks develop, then the refractory should be
replaced. Toreplace therefractory bricks,follow
these steps (see Figure 4):
1. Remove the baffle refractory and it’s iron angle
support;
2. Removethefrontrefractory;
3. Removethebottomrefractory;
4. Removethesidesrefractories*;
5. Remove the back refractory.
*Holdtheback refractorywhenthe lastsiderefrac-
tory is removed, to prevent the back refractory to
fall in the firebox.
DOORS ADJUSTMENT
Glass doors may lose their adjustment during
transportation or installation of the fireplace.
A wrong adjustment may cause a loss in
combustion’s efficiency and control. The glass
doors must be parallel, at the same height and
must almost touch each other when closed.
Maximum spacing between the door's glass
is one sixteenth of an inch (1/16’’).
The glass doors can be adjusted by loosening
the three (3) screws of the hinges’ supports
(see fastening screws in Figure 5). If a minor
angular adjustment is needed, you may loosen
only two (2) of the three (3) screws using the
other as a pivot point.
HOW TO USE THE RETRACTABLE DOORS
AND FIRESCREENS
The HE43-2 fireplace features retractable doors
and firescreens in order to allow a wider view
of the fire and save space when the doors are
opened. To retract the doors, simply open them
at 90° and push them into the opening on the
side of the firebox. The same procedure applies
for the retractable firescreens. (see Figure 3).
Note: Do not operate the fireplace with both
fire-screen and doorsclosed at thesametime.
Figure 3 - Sliding Doors / Firescreens
WARNINGS
• Use only a Security Chimneys International glass doors, specifically
designed for the HE43-2 fireplace.
• The fireplace cannot be operated without doors or firescreens.
Consult your dealer to select the correct replacement door(s) or

FIREPLACE INSTALLATION
Locating The HE43-2 Fireplace
A. The best location to install your fireplace is
determined by considering the location of
windows, doors, and the traffic flow in the
room where the fireplace is located, allow-
ing space in front of the unit for the hearth
extension and the mantel, and taking into
consideration the location of the outside air
kit and chimney.
GLASS CARE
Glass Replacement
The glass used for the HE43-2 fireplace is a high
temperature ceramic glass (1,400° F / 760° C).
If the glass breaks, it must be replaced with
an identical ceramic glass. Tempered glass
or ordinary glass will not withstand the high
temperatures of the HE43-2 fireplace. Replace-
mentglassshouldbepurchased from a Security
Chimneys International dealer (see “Replace-
ment Parts”, Page 24). DO NOT OPERATE THE
UNIT WITH CRACKED OR BROKEN GLASS. To
remove the glass, unscrew the frame fastening
screws (see figure 5),removethe interiorframe
and the glass.
Glass Cleaning
The HE43-2 fireplace is designed to keep the
glass clean under normal operating conditions.
Tocleantheglassthereareanumberof specially
designed cleaners. Your authorized Security
Chimneys International dealer can recommend
a suitable cleaner. Regular household glass
cleaners will not clean creosote.
Do not use
abrasives such as steel pads, steel wool or
oven cleaner as they will scratch the glass.
DO NOT USE CHEMICAL GLASS CLEANERS
ON PAINTED SURFACES AS IT MAY CAUSE
THE PAINT TO PEEL.
CAUTION:DONOTALLOWWINDOW CLEANER
TO GET IN CONTACT WITH DOOR GASKET OR
PAINT ON FACADE OR DOOR. ONCE CLOSED,
CONTACT OF GLASS CLEANER WITH THE
FIREPLACE FACADE CAN PROVOKE PAINT
PEELING OFF.
Gasket Replacement
Remove the doors from the unit (see Page 7)
andlayeachdooron a cleanunabrasive surface.
To replace the gasket, first remove all of the old
gasket and gasket cement. Make sure that the
surface is totally clean before applying new
cement (a high temperature silicone caulking
rated at 500° F [260° C] is suitable) or adhesion
problems may result. Apply gasket cement to
the gasket channel and install the new gasket.
This replacement part is available from your
Security Chimneys International dealer in the

to combustible materials, secure assembly of
components parts, the height of the chimney
system, the proper use of accessory equip-
ment and the techniques used in using finish-
ing materials applied to fireplace surrounds,
hearth extensions and wall coverings. Each
of these topics will be covered in greater detail
throughout this manual. Please give special
attentiontothese instructions as youprogress
with your installation.
Fireplace Installation Procedure
1. Move the fireplace into the desired position
(follow the recommendations below for
enclosure).
2. Install the outside air assembly (or assem-
blies) - refer to Page 13.
3. Installtheenclosuresurroundingthefireplace
(see Pages 9 through 12).
4. Install the hearth extension (see Page 10).
Make sure the gap between the fireplace and
the hearth extension is sealed.
LOCATING THE FIREPLACE
Do not place the fireplace on carpeting, vinyl or
other soft surface floor coverings. It may, how-
ever, be directly placed on flat wood, plywood,
particle board or other hard surface materials.
8. This fireplace has provision for the installa-
tion of a gas pipe and is intended only for
connection to a decorative gas appliance
incorporating an automatic shutoff device
and complying with ANSI Z21.60-M96/CGA
2.26-M96, Standard for Decorative Gas Ap-
pliancesforInstallationin Solid-Fuel Burning
Fireplaces (reference Clause 4.1.3 T).
9. The HE43-2 fireplaces are sold with factory
installed doors. The outside combustion
air kit is mandatory and is included with the
fireplace. Optional blowers and decorative
trims are available.
ADJACENT WALL
A wall perpendicular to and in front of the fire-
place front facing must be at least 18" (460mm)
from the fireplace opening. A wall at 45º to the
front facing and starting at the fireplace’s outer
edge is permitted. Projections within this area
are permitted. See Figure 7.

ENCLOSURE
1. WARNING: Do not place loose insulation or
any other material in the space around the
fireplace or the chimney. Insulation placed
on or around the fireplace or chimney may
cause adjacent wood to overheat and catch
on fire.
2. The fireplace must be installed against a
finished wall (like drywall finish). It must
not be installed against a vapor barrier or
exposed insulation (see Figure 10).
3. The fireplace is zero clearance. Combustible
materials like wood, plywood, particle board
or drywall can be in direct contact with the
fireplace reinforcements. Two inch (50 mm)
clearance to combustibles must be kept
around the chimney.
4. WARNING: The top of the fireplace is not
zero clearance. Do not place any insulating
material in the space above the fireplace for a
height of 7 feet from the base of the fireplace.
5. Do not block the fireplace’s hot air vents or
air inlets as this will cause the fireplace to
overheat.
CHASE ENCLOSURE
Achaseisaverticalbox-likestructureconstruct-
ed to surround the fireplace and chimney. Refer
to Figure 10 for a typical chase configuration.
A chase should be constructed and insulated
just like any outside wall. In a cold climate,
we recommend the base of the chase should
also be insulated between the solid continuous
basebeneath thefireplace and theoutside base.
Chase insulation in a cold climate installation
is not required for safety.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Mantel
A wood mantel, if installed, must be at least
48" (1.2 m) above the base of the fireplace (see
Figure 8B). There is no restriction regarding
the length or the width of the mantel.
Hearth Extension Requirements
(refer to Figures 8A and 8B)
A non-combustible hearth extension must be
built in front of the fireplace and extend out on
both sides. Hearth extensions must be con-
structed according to the following guidelines:
1. A layer of sheet metal 0.018" (0.45mm) thick
or 3/8" (9mm) thick insulating board or any
other material (tiles, marble, granite) with
equivalent heat resistance may be used.
Check with the local building authorities
before installing to determine what other
materials are acceptable in your area.
2. The hearth extension should be secured to
the floor. The gap between the fireplace and
the hearth extension must be sealed. The
suppliedsafetymetalstrip mustbepositioned
as follows: One half under the front of the
fireplace and the other half must extend on
the floor over which the hearth extension will
be built (see Figure 8A).
* The safety metal strip must cover the entire
width of the fireplace.
3. On a raised base or raised hearth, a “Z” shape
piece of metal must be fabricated to join the
bottom of the fireplace to the floor (see note
1 in Figure 8A).
Hearth extension of an elevated fireplace
must respect the same minimal dimensions
as a fireplace installed directly on the floor
(figure 8B).
Cold Climate Installations
Climates where temperatures will fall below
32° F (0° C).
The heating performance of the appliance will
vary depending upon the level of insulation,
housedesign,howtheappliance isoperated,etc.
If this fireplace is being installed in a cold
climate, it is especially important to seal all
cracks around the fireplace and wherever cold
air could enter the room with noncombustible
material. Also, the outside air inlet duct should
be wrapped with noncombustible insulation to
minimize the formation of condensation. Do
not place insulation materials directly against
the chimney sections. We recommend thatyou
use the insulated wall radiation shield since it
will maintain the home’s thermal barrier. AC
chimney is NOT recommended in very cold
climates (in areas with temperatures often get
below 0°F (-18°C).
Figure 8B
WARNING: THE HEARTH EXTEN-
SION IS TO BE INSTALLED ONLY
AS ILLUSTRATED.
The crack between the fireplace
and the hearth extension must be
sealed with a non-combustible
material such as sand-cement
grout.

Outside Air Assembly
(Fireplace and AC Chimney)
The outside air assembly is mandatory for
the fireplace and the AC chimney.
During operation, the fireplace requires air for
combustion and draws air out of the house. It
may starve other fuel burning appliances such
as gas or oil furnaces. As well, exhaust blowers
and blower driven appliances may compete for
air, causing a negative pressure in the home,
resulting in smoke entering the home from
the fireplace. This situation is aggravated in
modern airtight houses.
To overcome this potential problem, the instal-
lationof an outsideair assembly is requiredto
provide outside combustion air to the fireplace.
Outside Air Installation
(Fireplace and AC Chimney)
The outside air assembly must be installed
according to the following guidelines:
1. The maximum length of 4" I.D. (100 mm)
insulated flexible duct is 20 feet (6.1 m). If a
longerduct isrequired, usea6" I.D. (150mm)
insulated flexible duct. The maximum length
is 40 feet (12 m). Refer to Figures 12B and
12C for connections.
2. The duct and register may be installed above
or below floor level.
3. The outside air register must not be installed
more than 10 feet (3.1 m) above the base of
the fireplace.
4. The outside air assembly must draw air from
outside the house. It must not draw air from
theattic,thebasementoragarage(seeFigure
6 on Page 8).
5. Locate the outside register where it will be
well away from automobile exhaust fumes
or other vents.
6. The outside air register should be installed
where it is not likely to be blocked by snow
or exposed to extreme wind.
7. It is recommended to install the outside air
register at floor level. However, if you must
raise the air register above the fireplace level,
you will have to make a loop to the floor with
the flexible pipe to prevent from causing a
draft in the outside air register (see Figure
12 Detail A).

INSTALLATION OF THE BLOWER KIT MODEL UZY5
NOTE: This blower kit can easily be installed when the fireplace has a
pre-installed junction box. You just have to plug them in.
Rating: 120 Volts, 60Hz, .63A.
The blowers have magnetic blower mounts. The junction box (factory
installed on approved fireplaces for the use of this blower kit) must be
connected to 120 VAC service before permanently enclosing the fireplace.
The access hole for connecting the 120 VAC is located on the lower right
exterior side of the fireplace.
Installation instructions:
1. Open the bottom louver of the fireplace.
2. Place each blower kit into the fireplace side opening 1" from the
back of the fireplace.
3. Install the automatic blower activator on the side of the firebox (the
blower activator has a magnetic mount).
4. Plug the blower kit into the junction box.
5. Ground both blowers to the back panel using the green screws (see
Figure 13).
NOTE: The fireplace must be electrically connected and grounded in
accordance with local codes or in the absence of local codes, with the
current CSA C22.1 Canadian Electrical Code. For U.S.A. installations,
follow local codes and the National Electrical Code ANSI/NFPA No 70.
CAUTION: SHOULD THIS BLOWER REQUIRE SERVICING, THE POWER
SUPPLY MUST BE DISCONNECTED.
These blowers require periodic maintenance. Check the area in front of the
blowers and wipe or vacuum at least once a month during the burn season.

The knock-outs provided on the sides of the HE43-2 fireplace allow the
connection of insulated flexible pipe which enables you to heat adjacent
rooms up to 50 feet from the fireplace.
The ducting system must be installed as described below:
1. Fix the adaptor at the side of the fireplace by twist-locking the adaptor
to the fireplace. You can use more than one outlet on the fireplace
(Figure 14).
2. Attach the 5" flexible pipe, using the collars provided. Important: Make
sure that the plastic wrapping around the flexible pipe will not be in
contact with the fireplace.
3. Route the flexible pipe to the chosen location. The ducting system can
be installed either in an upper room or in a lower room.
4. Attach the flexible pipe to the blower, using the collars (Figure 15).
5. Fix the decorative grill blower adaptor to the blower.
6. Attach a standard 3" x 10" grill to the adaptor.
7. Install the blower thermostat in that part of the house to be heated by
the hot air duct. Do not install the blower thermostat in the room where
the fireplace is located. A cooling thermostat can be installed in the
same room as the unit. This thermostat will turn on the blower when
the room where the fireplace is located becomes too hot.
This option requires electricity. Make sure that the connections to the
blower have been made according to the local codes and comply with
their requirements.

CHIMNEY SYSTEM
GENERAL INFORMATION
The HE43-2 fireplace is listed only with Security Chimneys™ International
Ltd. chimney systems, models ASHT+ 8", S-2100+ 8", or AC 8". Do not
connect the fireplace to a masonry chimney, chimney liner, or other
brand of factory-built chimney.
The Oliver Macleod chimney models HT6103 and HT6000 are respec-
tively equivalent to Security Chimneys International ltd. Chimney
models ASHT and S2100.
In areas with continuous temperatures below 0º F (-18º C), the use of
an exterior chimney increases the likelihood of operating problems such
as low draft, high rate of creosoting and poor start up characteristics.
Exterior chimneys are also prone to down-drafting and flow reversal.
Installations locatedin abasement,incombinationwithoutsidechimneys,
are especially prone to flow reversal. In cold areas, air cooled chimneys
should not be used in an exterior installation.
Caution: AC chimney should not be used in very cold areas, where
temperatures are likely to fall below 0° F (-18° C), or altitudes above
4000 feet.
A chimney venting a fireplace shall not vent any other appliance.
The minimum system heights are indicated in Table 2.
In altitude, add 18" (450mm) to the chimney for every 2000 feet (600
m) above sea level.
All chimney installations must include at least one support. The maximum
length of chimney that can be supported by the fireplace is 12 feet (3.6 m)
for S-2100+, 18 feet (5.4 m) for ASHT+ and 26 feet (8 m) for AC chimney.
The chimney must extend at least 3 feet (915mm) above its point of
contact with the roof and at least 2 feet (610mm) higher than any wall,
roof or building within 10 feet (3 m) of it (see Figure 18).
If the chimney extends higher than 5 feet (1500mm) above its point
of contact with the roof, it must be secured using a roof brace or
guide wires.
A rain cap must be installed on top of the chimney. Failure to install a
rain cap may cause the fireplace to corrode and operate inefficiently.
Cutand framesquare holes in all floorsand theroof toprovide a 2" (50mm)
clearance between the chimney and any combustible materials. Do not
fill this 2" (50mm) space with any material (see Figure 19).
Portions of the chimney which may extend through accessible spaces
must be enclosed to avoid contact with combustible materials or dam-
age the chimney.
Note:2"clearanceto combustiblesaroundchimneycomponents required.
Note: Blown or fill type insulation materials must not be in contact with the
fireplace or in the enclosure frame as described in ‘’Enclosure’’ section.
Note: Local codes may not require firestopping at the ceiling levels for
outside chase installations. However, it is recommended for safety and
the reduction of heat loss.
Chimney Height
The total height of your completed fireplace system from the surface the
fireplace rests on to the chimney top must not exceed 60'. Chimney height
must also meet minimum height requirements, excluding the fireplace
height, indicated in Table 2. Refer to the minimum system height chart.
In altitude, add 18" (450 mm) to the chimney for every 2000 feet (600
m) above sea level.

CHIMNEYINSTALLATIONINSTRUCTIONS
1. Cut and frame the holes in the ceiling,
floor and roof where the chimney will pass
(see Figure 19). Use a plumb-bob to line
up the center of the holes. The hole sizes
are indicated in Table 3 for the floor and
ceiling holes and in Table 4 (Page 17)for
the roof holes.
Figure 19
2. Frombelow,install a firestopineachceiling/
floorseparation throughwhichthechimney
will pass. At the attic level, install an attic
radiation shield from above (see Figures
20A and 20B).
3. For ASHT+ and S-2100+ chimneys, place
the first chimney length on the fireplace. To
lock it into place, turn 1/4 of a turn clock-
wise. With the AC chimney you must use
a starting section before installing the first
chimney length (see Figure 21). Continue
installing chimney lengths making sure to
lock each length in place.
4. Every time the chimney passes through
a roof or a wall, install the appropriate
firestop. Whenyoureachthedesiredheight,
install the roof support (see instructions
included with the support).
5. Then, put the roof flashing in place and seal
the joint between the roof and the flashing
with roofing pitch. For sloping roofs, place
theflashingundertheupper shinglesandon
top of the lower shingles. Nail the flashing
to the roof, using roofing nails (Figures 22
and 23).
6. Place the storm collar over the flashing and
tightenit with theboltsupplied. Finally, seal
the joint between the storm collar and the
chimney, using silicone caulking.
7. Install the chimney cap. Once the chimney
cap is in place, the roof flashing can be
washed with a solvent or vinegar and then
painted with rust-proof paint.

OFFSET CHIMNEY INSTALLATION
After reaching the location requiring the elbow, proceed as follows. The minimum chimney height
excluding the fireplace height is shown in Table 2.
Notes:
• Must return to vertical before penetrating ceiling or floor.
• A maximum of 2 offsets are allowed.
After reaching the location requiring the
elbow, proceed as follows:
ASHT+/HT6103+/S2100+/HT6000+Chim-
neys
1. Install the first elbow. Turn it in
the required direction. Fasten it to
the chimney with the three (3) 1/2"
(12mm) metal screws provided.
2. Install the necessary lengths to achieve
the required offset. Lock the chimney
lengths together: it is recommended to
use three (3) 1/2" (12mm) screws. If the
offset length is made of two (2) chimney
lengths use an offset support halfway up
the offset. If penetrating a wall, install a
wall radiation shield (see Figure 27).
3. Use another elbow to turn the chimney
vertically. Secure the elbow, using three
(3) 1/2" (12mm) screws (provided with
the elbow).
4. Use a plumb-bob to line up the center of
the hole. Cut a hole for the chimney in the
ceiling/floor. Frame this hole as described
previously (see Chimney Installation
Instructions on Page 16).
5. From below, install a radiation shield
(Figure 20A).
6. A support (ST+ or SO+) must be used on
the first 15 feet section (5 m).
7. Continue with the regular installation.
AC chimney
1. Install thefirstelbow. Turnitintherequired
direction. To lock it in place, turn 1/8 of
a turn. Fasten the straps attached to the
elbow to the surrounding framing using
nails or drywall screws (Figure 25).
2. Install the necessary chimney lengths
to achieve the required offset. Lock the
chimney lengths together. If penetrating
a wall, use a wall radiation shield (Figure
27).
3. Use another elbow to turn the chimney
vertically. Lock it to the chimney. Fasten
the straps attached to the elbow to the
surroundingframing usingnailsor drywall
screws.
4. Use a plumb-bob to line up the center of
the hole. Cut a hole for the chimney in
the ceiling. Frame this hole as described
previously.
5. From below, install a radiation shield (see
Figure 20B).
6. Continue with the regular installation.
Note: When using AC chimney, an AC8SB
(H3801) starter section must be used before
installing an elbow. When an offset is needed
immediately off the top of the fireplace, an
elbow starter section, AC8SB30 (H3802) is
available.

ANGLED WALL RADIATION SHIELD
(RSM+, RSMI30, RSMI45)
When traversing a combustible wall with the chimney at a 30° or 45°
angle, an angled firestop and/or wall radiation shield must be installed.
Only one is required (Figure 27). Table 6 gives recommended hole size
for installing a wall radiation shield.
Note: 45° angle installation for Canada only.
In cold climate locations (climates where temperatures will fall below
32° F / 0° C), we recommend that you use the insulated wall radiation
shield since it will maintain the home’s thermal barrier.

CHIMNEY ADAPTOR (S-2100+ / HT6000+) CANADA ONLY
The fireplace is normally supplied with a chimney adaptor suitable for the
ASHT / HT6103+ chimney. If you want to install a S-2100+ / HT6000+
chimney, an adaptor is available (8UCA) (Figure 29). A separate starter
section will also be required if AC chimney is installed.
UNIVERSAL ROOF SUPPORT INSTALLATION
This support has three possible uses:
1. For ASHT+ and S-2100+ chimneys, it must be used on a roof to
support the chimney.
2. It may be used on a floor, ceiling or roof above an offset to support
the chimney above the offset.
3. It may be used on a floor, ceiling or roof as a supplementary support
when the chimney height exceeds 15 feet (4.6 m.).
Table 7 gives maximum height of supported chimney.
NOTE: For the AC chimney, a support section (AC8SL) must be used
every 40’ (12 m) instead of the universal roof support (ST).
For roof support installation, refer to the instructions provided with the
support.
Universal Offset Support
This support is used to support the chimney above an offset. When
the chimney offset is used to traverse a wall, this support may be used
on the wall to support the chimney. The maximum heights are given in
Table 7. For offset support installation, refer to the instructions provided
with the support.
Figure 28
CHIMNEY CHASE AND MULTIPLE TERMINATIONS
For the purpose of this manual, a chimney chase is considered a part of
the chimney system rather than part of a building. The termination must
be placed a minimum of 18" (460mm) above the chase.
For installation where more than one chimney is located in the same chase
or within the same general area, we suggest that their terminations be
separated by at least 16" (410mm) horizontally and 18" (460mm) verti-
cally. This separation is to prevent smoke migrating from one chimney
to another (see Figure 28).
