OPERATING THE LADERA FIREPLACE
Fuel
USE SOLID NATURAL WOOD FUEL ONLY.
The Ladera fireplace is designed to work best
when fueled with dry seasoned natural wood
only. Hardwoods are preferred to softwoods
since the 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 difficult to burn and will result in lower
efficiency, increasedcreosotinganddepositson
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 branches or 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.
Burning unapproved fuel, resulting in excessive
pollutantsbeingemitted,may beprohibited and
subject to a fine or other penalty by the authority
having jurisdiction in your area.
Processed firelogs can be used. Although, do
not poke or stir the logs while they are burning.
Use only firelogs that have been evaluated for
the application of fireplace and refer to firelog
warnings and caution markings on packaging
prior to use.

First Fires
Beforeusingthefireplacemakesuretoremove
the plastic wrapping and EPA label on 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.
Building a Fire
(starting and maintaining a fire)
Note: Leave 1/2 inch of ashes at the bottom
of the firebox.
To start a fire, place several crumpled up balls of
newspaperin the firebox. Placesmalldrypieces
of kindling on top of the paper, criss-crossing
the kindling so that there are air spaces in be-
tween. 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 door.
Once the kindling fire is well established, cord
wood can be added (see Primary Air Combus-
tion Control section for proper operation of the
air controls).
The unit will burn best with 1-2 pieces of cord
wood spaced 1 to 2 inches apart and allowing air
to get under the fuel. Criss-crossing or arrang-
ing the fuel so that air can get underneath, will
help the fire to get started easily. The unit should
be operated with the air control fully open long
enough to get the cord wood well ignited.
COMBUSTION CONTROLS
Primary Air and Air Boost Controls
There is no flue damper in the Ladera™ fire-
place. As is common with air tight stoves,
the combustion air control sets the flow of air
entering the firebox. This allows for a more
For instance, a long chimney will necessitate
closing the damper more. To obtain the proper
combustion, close the damper completely, then
open it about 1/4” to 1/2” (6.4mm to 13mm).
Two medium size pieces of wood should be
burning on a bed of hot coals. The heat output
will be approximately 25,000 BTU per hour and
the loading time will be about every 3-4 hours.
Softwoods may be burned using this method
but the time will be substantially reduced.
Slow Combustion
When the air combustion control is completely
closed,thefireplaceisinaslowcombustionphase.
If the hearth is hot enough, slow combustion will
not extinguish the fire, but there will be a notice-
able change in the flame pattern. The flames will
be slow and may appear dirty if the wood is too
wet (moisture content of 20% and more). Do not
allow the wood to burn without flame, since this
will produce excessive creosote in the unit.
Creosote may accumulate on the glass door.
This method of burning should be used only
after operating the Ladera fireplace with the air
control opened to produce a hot fire for about
an hour or at medium pace for at least three
(3) hours. Slow combustion can be used at
night in order to reduce the heat output and
to prolong the burn. The loading time will be
between 6-8 hours.
REFUELING FOR BEST PERFORMANCE
The Ladera fireplace will operate best if at-
tention is given to operating the unit with the
damper fully opened 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. A temperature of 500º C (932º F)
and up, with a visible flame, in the upper part
of the firebox indicates a maximum efficiency.
To obtain this temperature, the fireplace must
be operated with the primary air and air boost
controls fully opened during 10 to 20 minutes
after reloading, depending on the heat and on
the moisture content of the wood.
Onceyouhavereachedthedesiredtemperature,
the air boost can be closed and the primary air
set to a medium setting. You know you have
reached the desired temperature when, closing
the primary air control, you can see a flame
at the top of the firebox. The benefit of this
technique will be cleaner glass, less creosoting,
greater efficiency and the most pleasing fire for
your enjoyment.
SMOKING –
CAUSES AND TROUBLESHOOTING
To reduce the likelihood of smoking when open-
ing the door, set the combustion air controls 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:

precise control of the fire. The combustion air
controlis located belowthe door onthe leftside.
The main source of air (primary air) entering
the firebox can be diminished by moving the
air combustion control from left to right. The
primary air is fully opened when the air control
is completely moved to the left. The air control
device can also be used to add an extra boost of
air especially during fire start up and reloading
of the unit.
Pullingthe aircombustioncontrolwill inducean
airboost atthe baseof thefire allowingan easier
fire start up. When the fire is well established,
the control can be pushed in to shut down the
air boost allowing for a longer burn time. The
combustion air control should be in the closed
position (primary air and air boost) when the
fireplace is not in use. This will minimize air
leakage up the chimney. The combustion air
control should be opened before opening the
door to minimize the possibility of back draft
coming into the room.
Accelerated Combustion
The maximum heat output for the Ladera
fireplace is achieved by burning with the door
closed and the combustion air opened. By this
method, the Ladera fireplace can produce the
maximum BTU of heat per hour. However, it
will be necessary to reload with wood every one
or two hours. This is the least efficient method
of burning the Ladera fireplace.
Use caution when firing with the combustion
air control wide open. Only burn cord wood in
this manner. Small dry pieces of softwood and
construction scraps will burn very intensely us-
ing this method and may damage the firebox.
Medium Combustion
Thisis therecommendedmode ofoperating the
Ladera fireplace and should be the one normally
used since it will deposit the least amount of
creosote on the glass and in the chimney. The
combustion air control must be 3/4 closed and
pushed in to close the air boost. The precise
setting will depend on many factors, including
chimney length and the moisture content of
the wood.

A. Negative pressure in the house
As the fire burns, air goes up the chimney.
This air must be replaced through leakage
intothehouse or throughtheoutsideair duct
(optional). When operating the Ladera™
fireplace,opena nearbywindow temporarily
to check if there is adequate replacement air
supply.
B. Fans operating (e.g.: range hood)
These fans draw air out of the house and
mayactuallycauseanegativepressure inthe
house. Turn off all fans and open a nearby
window to determine if this is the cause of
the problem.
C. Wet wood
Wetor tarred woodwillsmoulderand smoke
insteadofburnproperly. Yourdealercan help
youdetermineif youhaveproperlyseasoned
wood for burning.
D. 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.
E. Chimney not long enough
The minimum chimney height is twelve
(12) feet (3.7 m) not including the fireplace
height. 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
installedwithoffsets, the minimumchimney
height is fifteen (15) feet (4.6 m). Additional
height will increase draft and will decrease
the tendency to smoke.
F. Poor chimney draft
With no fire, there should be sufficient draft to
exhaust cigarette smoke introduced under the
baffle. Chimneys installed against an outside
wallwithout protection or a basementinstalla-
tion 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. Do not block the hot air vents to the fire-
place 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.
D. Donotburndriftwood which has been in the
ocean or salt water. The salt will corrode
the firebox and chimney.
E. Do not burn wood in the area in front of the
grate.
F. Do not abuse the unit by burning paper, or
cardboard or construction material such as
pressed wood, plywood or lumber.
G. 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.
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
combined with proper operation will prevent
chimneyfires.Keep yourchimney clean. Do not
allow more than 1/16” (1.6 mm) creosote build
upin yourchimney. The amountof creosotewill
depend on variables such as frequency of use
and type of fire. We recommend that you:
A. Initially inspect the chimney system weekly.
From 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 expect chemical cleaners to keep
your chimney clean. The rain cap can be
removed for inspection and/or cleaning of
the chimney.
Dealing With a Chimney Fire
Regular chimney maintenance and inspection
canpreventchimneyfires. Ifyouhavea chimney
fire, follow these steps:
1. Close the fireplace door and the combustion
air controls.
2. Alert your family of the possible danger.
3. If you require assistance, alert your fire
department.
4. 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 a
dangerous steam explosion.
Finish Door Casing Care
Use a glass cleaner and a soft cloth to polish
the casing. Do not use abrasives such as steel
wool, steel pads or an abrasive polish for they
may scratch the casing’s finish.
5. Check outside to ensure that sparks and hot
embers coming out of the chimney are not
igniting the roof.
6. Do not use the fireplace again until your
chimney and fireplace have been inspected
by a qualified chimney sweep or a Fire
Department 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. Slide the front baffle to the front of the
unit.
2. Lift the back baffle and slide it over the
front baffle. You now have access to the
chimney

REFRACTORY REPLACEMENT
The intense heat of the fire will normally cause
hairline cracks in the refractory. These cracks
can be minimized by proper curing 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. To replacetherefractorybricks,follow
these steps (see Figure 3):
1. Remove the bottom refractory
2. Remove the front refractories
3. Remove the left side refractory
4. Remove the right side refractory
5. Remove the back refractory
6. Remove the front ceramic baffle
7. Remove the rear ceramic baffle
To install the new refractories, follow the above
steps in reverse.
Figure 3
Figure 4
DOOR REMOVAL
To remove the door, simply pull the door up from the hinges (see Figure 4). The door adjustment
has been set at the factory. If the fit is still not perfect, you can adjust the door using the hinge
screws.
DOOR ADJUSTMENT
The door may need to be adjusted to be completely airtight. The gaskets’ air-tightness can be
adjusted using two adjustment screws located on the right side of the fireplace facade (An Allen
key #1/8 – not supplied - will be necessary for this adjustment).
Checking Door Seal
A one-inch strip of paper may be used to perform a test of the integrity of the door seal. Close
the door on the paper in at least eight points. It is normal to feel only a slight amount of friction.
The door gasket does not need to be “tight” in all areas, since a small amount of leakage is not
hazardous or detrimental to the performance of your fireplace.

leaving 1/2 inch of ashes in the firebox.
Remove ashes only when the fire is out and
the ashes are cold (24 to 48 hours after the
fire is out).
Do not leave the ashes in the house as they give
off carbon monoxide and other toxic gases.
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

If possible, you should choose a location where
thechimneywillpassthrough the housewithout
cutting floor or roof joists (see fireplace dimen-
sions Page 9).
Usually, no additional floor support is needed
for the fireplace. The adequacy of the floor
can be checked by first estimating the weight
of the fireplace system. Weights are given
on Page 23. Note the floor construction and
consult your local building code to determine
if additional support is needed.
The Ladera fireplace may be installed directly
on the floor or on a raised base (for proper
guidelines, refer to “Hearth Extension Require-
ments”)and a minimumof 6’8” (2 m) measured
from the base of the appliance to the ceiling
is required.
When selecting the location, the chimney outlet
position and the direction of the wind are impor-
tant factor affecting the chimney performance.
To allow a maximum draft and to reduce wind
turbulence, the chimney must:
• Penetrate the highest part of the roof.
• Be installed as far as possible of roof offsets,
trees or any other obstructions that may
cause wind turbulence and back drafts in
the chimney.
• The least amount of offsets (elbows) pos-
sible.
GLASS CARE
Glass Replacement
The glass used for the Ladera™ fireplace is a
hightemperature ceramicglass(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 tem-
peratures of the Ladera fireplace. Replacement
glassshouldbepurchasedfromaLennoxHearth
Products dealer (see “Replacement Parts”,
Page 23). DO NOT OPERATE THE UNIT WITH
CRACKED OR BROKEN GLASS.
Glass Cleaning
The Ladera fireplace is designed to keep the
glass clean under normal operating conditions.
If the Ladera fireplace is operated continuously
with the combustion air controls closed, the
glasswilltendtogetdirtyunlessthe fuel,firebox
and glass are maintained at hot temperatures
(see “Refueling For Best Performance”). To
clean the glass, there are a number of specially
designed cleaners. Your authorized Lennox
Hearth Products dealer can recommend a
suitable cleaner which is available in your area.
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.

FIREPLACE INSTALLATION
Locating The Ladera Fireplace
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, allowing space
in front of the unit for the hearth extension and
the mantel, and taking into consideration the
location of the hot air ducts (optional), outside
air kit (optional) and chimney.
Gasket Replacement
Remove the door from the unit (see Page 6)
and lay it on a clean unabrasive 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.

Framing, Facing And Mantel
The construction of the framing, facing, and
mantel must be in accordance with the stan-
dards and the following illustrations (Figures
8 and 9):
A. Frame the fireplace using 2” x 3” or heavier
lumber.
B. WARNING: Combustible materials can-
not be used in the space directly above
the fireplace, except for the studs above
the facade that support the facing and
mantel. This area must remain empty
for a height of 6’8” (2,032 mm) mea-
sured from the base of the appliance.
C. Frame the fireplace with vertical studs at the
sides of the fireplace running from floor to
ceiling (see Figure 8). If combustible facing
is to be used, position the studs back, from
the front edge of the fireplace (a space that
is the thickness of the facing material, so
that the facing can be installed flush with the
fireplace facing). Frame headers between
the vertical studs only as follows:
• Place 2” x 3” or 2” x 4” headers,
only along the upper part of the front,
side and back faces (some codes
may require a 2” x 6” on an outside
bearing wall). Do not put wood or
any combustible material within the
area above the fireplace except on the
front facing.
• Place headers only as required to sup-
port the facing and mantel.
D. WARNING: The fireplace must not be in
contact with any insulation or loose fill-
ing material. Cover the insulation with
drywall panels around the fireplace.
HEARTH EXTENSION REQUIREMENTS
The Ladera™ fireplace may be installed directly
ona combustiblefloor. Thesuppliedsafetymetal
strip must be positioned 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 7A).
* The safety metal strip must cover the entire
width of the fireplace
The combustible floor in front of the fireplace
must be covered with at least a 1/2 inch of
non-combustible material (tile, marble, stone,
etc). See Figure 7B.
COLD CLIMATE INSTALLATIONS
Climates where temperatures will fall below
32° F (0° C).
The heating performance of the appliance will
varydependinguponthelevelofinsulation,house
design, how the appliance is operated, 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 that you
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 below 32°F (0°C).

Once the repair is done, it is mandatory to
apply a new high temperature black cement
(Mill-Pack, available from your retailer)
sealing the access plate and all screw holes.
Because the Ladera fireplace is an air tight
fireplace, failure to do so will reduce fireplace
efficiency. Tightly screw the access plate back
on place and reinstall the bottom refractory.
HOT AIR DUCTING INSTALLATION
The Ladera™ fireplace is approved for use with
a Gravity kit (hot air ducting system).
Gravity Kit
The gravity kit is designed for double hot air
outlets and includes: (See Figure 14).
- Two (2) telescopic lengths 8” I.D.
- Two (2) 90º elbows 8” I.D.
- Two (2) hot air outlet kits
(grill and frames)
- Two (2) adaptors
See Gravity Kit Accessories Page 21.
For safe installation, the gravity kit must meet
the following requirements:
Minimum height* 68” (1,727 mm)
Maximum length See Figure 15
* The height of the louver must be measured
from the base of the Ladera fireplace to the
middle point of the louver.
Theonlyblowerthatcan be usedwiththegravity
kit is the one sold with the fireplace.
To extend the double outlet system, it will be
necessary to purchase two adjustable lengths
(7B26ZL2A).

FIREPLACE BLOWER
The fireplace is equipped with a blower. It is
located in the bottom of the fireplace towards
theback.It uses120Vand must beconnectedto
the main electrical circuit by a qualified electri-
cian prior to enclosing the fireplace.
For connection, use the electrical box supplied
with the unit located on the bottom right side
of the fireplace. To access the electrical box
remove the four screws, pull out the plate and
box and install the electrical receptacle.
A wall on/off switch must be installed to control
the blower. An optional heat switch and variable
speed control are available (see Page 21).
If installed, the heat activated switch must be
connected to the blower main cable and the
magnets must be stuck under the fireplaces
firebox accessible through the side electrical
box access plate.
If a repair must be done after the fireplace is
installedanaccessplateislocatedunderthebot-
tom refractory. Remove the bottom refractory,
unscrew the access plate, clean black cement
sealing the access plate and do the repair.
WARNING: Both pipes of
the double hot air outlet
must be installed. Any oth-
er installation may cause
fire and void warranty.
11
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
When installing the double outlet system, the
hot air outlets can be installed in the same room
as the fireplace, or one or both of the outlets
can be installed in adjacent or upper rooms.
Installing the ducts at different elevations will
tend to exhaust more heat out of the higher
outlet (Figure 15).

2. Maintain at least a 2” (50 mm) clearance
between the ducts and any combustible
material; the required hole size is 13” x 13”
(330 mm x 330 mm).
Exception #1: For the grills, the fram-
ing can be 10-3/4” x 10-3/4” (275 mm
x 275 mm) to provide the clearance as
required by the integral spacers on the
double outlet duct system.
3. The maximum number of elbows in a run of
duct is two.
4. Maintain at least 6-1/2” (160 mm) clearance
from the outlet grill framing to a combustible
ceiling, side wall, mantel or floor.
5. When traversing a combustible wall or floor,
a firestop must be installed at the wall or floor
penetration. The hole size must be 13” x 13”
(330 mm x 330 mm)
6. Do not connect the hot air ducts to a central
heating system. Malfunction of the heating
system’s blower will cause the fireplace to
overheat. A furnace duct is only single wall
and not double wall as is required for the
Ladera™ fireplace hot air exhaust.
7. Use only Lennox Hearth Products grills and
components as described in this manual.
Other grills or registers, for example, may
be too restrictive and may overheat the
fireplace or ceiling.
8. Do not use insulated flexible ducts as they
will overheat.
9. Do not use tees or any other components
than the ones specifically listed here.
10.Never allow the ducting to pitch down as
hot air will be trapped creating a fire hazard.
Never route the ducting downwards.

The knock-outs provided on the back and on
the sides of the Ladera™ fireplace allow the
connection of insulated flexible pipe which
enables you to heat adjacent rooms up to 50
feet from the fireplace hot air outlet.
The ducting system must be installed as de-
scribed below:
A) Remove knock-out plate and cut insulation
the adaptor at the back and/or the side of the
fireplace. Fix the adaptor by twist-locking it
to the fireplace. You can use more than one
outlet on the fireplace (see Figure 17).
B) 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.
C) Route theflexiblepipetothechosenlocation.
The ducting system can be installed either
in an upper room or in a lower room.
D) Attach the flexible pipe to the blower, using
the collars (Figure 18).
E) Fix the back draft damper to the blower
outlet.
F) Attach a flexible pipe to the fan / flexible pipe
adapter (square to round) and stretch it up
to the location where the heat is required.
G) Atthatpoint,the flexiblepipecan beattached

H) Install the blower heating and cooling ther-
mostat (HCTW) in that part of the house to
be heated by the hot air duct. The thermostat
can be switched to a cooling thermostat and
installed in the same room as the unit. This
thermostat will turn on the blower when the
roomwherethe fireplaceislocatedbecomes
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 (see instruction provided
with the thermostat). For more information

OUTSIDE AIR KIT (fireplace and AC chimney)
The outside air kit is optional on the Ladera™ fireplace, but mandatory on
the AC chimney. It can be burned drawing air only from the house. When
the fireplace is in operation with the door closed, it will pull only a slight
amount of air from the house. Nevertheless, the outside air kit might be
mandatory in your jurisdiction, check your local building code.
To install an outside air intake on the fireplace:
1. Remove the obstruction plate and the access plate (both are super-
impose) located on the bottom of the left side (Figure 19, part 2).
2. Screw the obstruction plate inside the primary air box using only two
screws on the bottom (Figure 19, part 3).
3. Reinstall the access plate exposing the 5 inch diameter hole topped
by a triangle (Figure 19, part 4).
Figure 19

Outside Air Installation
The outside air assembly may be installed according to the following
requirements:
A) Duct length should be kept to a minimum. The maximum length of a
4” interior diameter (100 mm) insulated flexible duct is twenty (20)
feet (6.1 m). (See note below).
B) The air intake register must not be installed more than ten (10) feet
(3050 mm) above the base of the fireplace.
C) The fresh air must come from outside the house. The air intake must
not draw air from the attic, basement or garage.
D) The air intake should be installed where it is not likely to be blocked by
snow or exposed to extreme wind and away from automobile exhaust
fumes, gas meters and other vents.
E) The duct and register may be installed above or below floor level.
Make a 4-1/4” (110 mm) hole in the outside wall of the house at the chosen
location. From outside, place the outside air register in the hole (open
side down) and fasten the register to the wall with screws as shown (see
Figure 20). Slip the pipe into the insulated sleeve. Place the insulated
pipe over the register tube and over the fireplace’s outside air connector
(see Figure 21). At each end, carefully pull back the insulation and plastic
cover exposing the flexible pipe. Using the aluminium tape provided,
wrap the tape around the joint between the flexible pipe and the air inlets.
Carefully push the insulation and plastic cover back over the pipe. Using
aluminium tape, fasten the plastic cover in place.
NOTE: We recommend not to exceed twenty (20) feet of 4” flexible pipe.
If you require a longer length we recommend that you use a 5” diameter
flexible pipe for the complete run up to thirty (30) feet and a 6” diameter
pipe for a run of up to forty (40) feet.

THE CHIMNEY SYSTEM
Chimney Installation Notes
1. If possible, install an interior chimney as it will provide better perfor-
mance. In areas with continuous temperatures below -18° C (0° F),
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-draft and
flow reversal. Installations, which are located on lower floors in the
house, such as in a basement, in combination with outside chimney,
are especially prone to flow reversal.
2. The Lennox Hearth Products fireplace model Ladera may be installed
only with Security Chimneys International 6” diameter chimney sys-
tems. The Ladera fireplace may also be installed with a 7’’ chimney
system (ASHT or HT6103) using the optional 6AW7 7’’ adaptor (7’’
AC chimney is not allowed). For more information refer to chimney
installation manual.
3. A chimney venting a fireplace shall not vent any other appliance.
4. The minimum chimney height is twelve (12) feet (3.7 m). In altitude,
add 18” (450 mm) to the chimney for every 2,000 feet (600 m) above
sea level.
5. All chimney installations must include at least one support. Re-
ducing the amount of chimney weight on the fireplace will help avoid
the noise created when the fireplace expands. This can be achieved
by having the chimney supported by the supports. The maximum
chimney length that can be supported by the fireplace is nine (9) feet
(2.75 m) for S-2100+/HT6000+, twelve (12) feet (3.7 m) for ASHT+
/ HT6103+ and 26 feet (8 m) for AC chimney.
6. 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 wall, roof or building within ten (10) feet (3m) of it (Figure 22).
7. If the chimney extends higher than five (5) feet (1,500 mm) above its point
of contact with the roof, it must be secured using a roof brace.
8. A rain cap must be installed on top of the chimney. Failure to install
a rain cap may cause corrosion problems.
9. Cut and frame square holes in all floors, ceilings, and roof that the
chimney will go through to provide a 2” (50 mm) clearance between
the chimney and any combustible materials. Do not fill this 2” space
with insulation or any other combustible material.
10.Portions of the chimney which may extend through accessible spaces
must be enclosed to avoid contact with combustible materials or
damage to the chimney.
11.When offsets are used, the pipe may not penetrate a ceiling or floor
unless it is running vertical (no 30° offsets).

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.
14 NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

CHIMNEY INSTALLATION
INSTRUCTIONS
1. Cut and frame the holes in the ceiling, floor
and roof where the chimney will pass (see
Figure 23). Use a plumb-bob to line up the
center of the holes. The sizes are indicated
in Table 2 for the floor and ceiling holes and
Table 3 (Page 16)for the roof holes.
2. From below, install a firestop in each ceiling/
floor separation through which the chimney
will pass. At the attic level, install an attic
radiation shield from above (Figure 24a).
3. ForASHT+/HT6103+andS2100+/HT6000+
chimneys place the first chimney length on
the fireplace. To lock it in place, turn 1/4 of
a turn clockwise. With the AC chimney, you
must use a starter section before installing
the first chimney length (Figure 25). Con-
tinueinstallingchimneylengthsmakingsure
to lock each length in place.
4. Every time the chimney passes through
a ceiling or a wall, install the appropriate
firestop. Whenyoureach thedesired height,
installthe roof support(Refer to 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 (see Figures 26 and 27).
For sloping roofs, place the flashing under
the upper shingles and on top of the lower
shingles. Nail the flashing to the roof, using
roofing nails.
6. Place the spacers and the storm collar over
the flashing, and tighten it with the bolt
supplied. 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.

Chimneys
1. Install the first elbow; turn it in the required
direction. Fasten it to the chimney with
the three (3) 1/2” (12 mm) metal screws
provided with the elbow.
2. Install the necessary chimney lengths to
achievetherequiredoffset. Lockthechimney
lengths together: it is recommended to use
three (3) 1/2” (12 mm) screws. If the offset
length is made of two (2) chimney lengths or
more, use an offset or roof support halfway
up the offset. If penetrating a wall, install
a wall radiation shield (see Figures 30 and
31).
3. Use another elbow to turn the chimney
vertically. Secure the elbow, using three
(3) 1/2” (12 mm) 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 (refer to section Chimney Instal-
lation Instructions).
5. From below, install a firestop (See Figure
24a).
6. A support (ST or SO) must be used on the
first 15’ section (5 m).
7. Continue with the regular installation.
AC Chimney
1. Install the first elbow. Turn it in the required
direction. To lock it in place, turn 1/8 of a
turn. Fasten the straps attached to the elbow
to the surrounding frame, using nails or
drywall screws (see Figure 29).
2. Install the necessary chimney lengths to
achievetherequiredoffset. Lockthechimney
lengths together. If penetrating a wall, use
a wall radiation shield.
3. Use another elbow to turn the chimney
vertically. Lock it to the chimney. Fasten
the straps attached to the elbow to the
surrounding framing using nails or drywall
screws.
4. Use a plumb-bob to line up the center of the
hole. Cuta holefor the chimneyintheceiling.
Frame this hole as described previously.
5. From below, install a firestop (see Figure
24b).
6. Continue with the regular installation.
Note: When using AC chimney, an AC6SB
starter section must be used before install-
ing an elbow. When an offset is needed
immediately off the top of the fireplace, an
elbow starter section, AC6SB30 (H3780), is
available.

ANGLED WALL RADIATION SHIELD
(RSM+ and RSMI30)
When traversing a combustible wall with the chimney at a 30º or 45º
angle, an angled firestop or wall radiation shield must be installed. Only
one is required.
Note: 45º angle for Canada only (RSMI45)
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.

Note: This illustration is
not to scale. It represents

the USA and a 45 degree
maximum offset is allowed
in Canada.

CHIMNEY SUPPORT INSTALLATION
Universal Roof Support
This support has three possible uses:
1. For ASHT+ / HT6103+ and S-2100+ / HT6000+, 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 sup-
port.
Table 6 gives maximum height of supported chimney.
NOTE: For the AC chimney, a support section must be used every forty
(40) feet (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 6. For offset support installation, refer to the instructions provided
with the support.

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” (460 mm) above the chase.
For installations where more than one chimney is located in the same
chase or within the same area, we suggest that their terminations be
separated by at least 16” (410 mm) horizontally, and 18” (460 mm) verti-
cally. This separation is to prevent smoke migrating from one chimney
to another (see Figure 32).
Figure 32
CHIMNEY ADAPTOR (S-2100+ / HT6000+) CANADA ONLY
The fireplace is 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 (6UCA) (Figure 33). A separate starter section
will also be required if AC chimney is installed.

INSTALLATION INSTRUCTIONS FOR MASONRY APPLICATION
WARNING: Before starting the installation, the masonry chimney
must be inspected by a qualified chimney sweep.
The following requirements must be respected:
1. The chimney must be absolutely clear of any soot residue or creosote.
Check for cracks, loose or missing bricks that could inhibit correct
installation of the liner.
2. The clearance to combustible must be a minimum of 1” between the
outside of the masonry and any wood framing or loose insulation.
3. The chimney must be built in accordance with the current building
code.
4. No other appliance can be connected to the same chimney.
5. The clearances to combustible for these fireplace connectors are 2”
on the side and bottom and 16” at the top.
6. The connector parts are not necessary if the connection between the
insulated length and the stainless steel liner is done within the masonry
chimney.
Installation:
The chimney must be relined with a stainless steel liner model TUBINOX
or Projet SS of the same diameter as the outlet of the fireplace.
For connection at a 30º angle, a special connector (BISUMA30) must be
used to connect the liner to the insulated chimney.
* IMPORTANT NOTE - The use of a 45º connector (BISUMA) is ap-
proved for use in Canada ONLY. Installations in the USA must use the
30º connector (BISUMA30).
Follow these steps:
1. Position the fireplace in its location. Temporarily install the ASHT+
elbow on the top of the fireplace and, using a level, mark with an oval
the location where the flue liner will enter the masonry chimney.
2. In the middle of the oval, drill a hole in the masonry chimney at 30º.
3. Increase the size of the hole until a 30º TUBINOX liner elbow can be
easily slipped through.
4. Slide the liner down from the top of the masonry chimney until you
reach the hole level.
5. Slip through the hole a 30º liner elbow and connect it to the liner.
6. Add a small liner section to the liner elbow which will allow the liner to
extend at least 12” (measured at the top of the liner) from the masonry
chimney.
7. Seal the opening around the liner with high temperature refractory
cement.
8. The next steps must be done in the following order:
See typical installation illustrated below.
A. Select the ASHT+ length that will fit between the elbow and the liner
so that it will slide at least 2” over the liner section (You may need to
cut the liner for a better fit).
B. Take that section and the BISUMA30 cover and slide it over the liner.
Make sure you have enough opening to be able to install the ASHT+
elbow without difficulty.
C. Install the 30º elbow on the fireplace.
D. Slide the length section back down on the elbow and twist lock the
two together.
E. Pull the cover down over the length and install the insulation pad over
the liner; be careful to cover the liner completely.
F. Slide back the cover over the insulation and fix it in place using the 3
metal screws supplied.
