OPERATING THE FIREPLACE
Fuel - USE SOLID NATURAL WOOD FUEL
ONLY.
This appliance is designed to burn
dry seasoned natural wood only (see Page 6
for a list of prohibited fuels). Failure to burn
proper fuels only will void the cert
the warranty of the appliance. 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, 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.
ification and
DO NOT OVERFIRE THIS HEATER
Attempts to achieve heat output rates that
exceed heater design specifications can result
in permanent damage to the heater.
First Fires
Before using the fireplace make sure to remove
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.
WARNING
Be careful adding wood fuel to the
fire or handling fireplace tools such
as shovels, tongs or pokers.
WARNING
The bottom refractory can be
cracked by excessive abuse such
as tossing heavy logs onto the
grate or gouging with fireplace
tools. Exercise caution when
adding wood to your fireplace.

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-crossing the
kindling so that there are air spaces 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 door. Once the
kindling fire is well established, cord wood can
be added (see Primary Air Combustion Control
section for proper operation of the air controls).
The unit will burn best with 2-3 pieces of cord
wood spaced 1 to 2 inches apart and allowing
air to get under the fuel. Criss-crossing or arranging 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 WCT4820WS
fireplace. As is common with air tight stoves,
the combustion air control sets the flow of air
entering the firebox. This allows for a more
precise control of the fire. The combustion air
control is located below the door on the left side.
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. Pulling the air combustion control
will induce an air boost at the base of the fire
allowing an 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 WCT4820WS
fireplace is achieved by burning with the door
closed and the combustion air opened and
pulled out. By this method, the WCT4820WS
fireplace can produce up to 55,000 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
WCT4820WS 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
using this method and may damage the firebox.

Figure 1
Medium Combustion
This is the recommended mode of operating
the WCT4820WS 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
(Figure 1). The precise setting will depend on
many factors, including chimney length and
the moisture content of the wood.
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”. Three medium size
pieces of wood should be burning on a bed of
hot coals. The heat output will be approximately
30,000 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, the fireplace is in a slow combustion
phase. If the hearth is hot enough, slow combustion will not extinguish the fire, but there
will be a noticeable 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 WCT4820WS fireplace with
the air control opened
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.
(Figure 1) to produce a
REFUELING FOR BEST PERFORMANCE
The WCT4820WS fireplace will operate best if
attention is given to operating the unit with the
damper fully opened
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.
Once you have reached the desired temperature,
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. If your fireplace is equipped
with a forced air system, make sure the central
blower is turned off during reloading to avoid
smoking problems.
(Figure 1) after refueling
SMOKING –
CAUSES AND TROUBLESHOOTING
To reduce the likelihood of smoking when opening 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:
A. 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 WCT4820WS fireplace,
open a nearby window temporarily to check
if there is adequate replacement air supply.
B. Blowers operating (e.g.: range hood) -
These blowers draw air out of the house
and may actually cause a negative pressure
in the house. Turn off all blowers and open
a nearby window to determine if this is the
cause of the problem.
C. Wet wood- Wet or tarred wood will smoulder
and smoke instead of burning properly.
dealer can help you determine if you have
properly seasoned wood for burning.
D. Dirty or blocked chimney- Check to make
sure the chimney is clear and clean.
call a certified chimney sweep or use a
properly sized chimney brush to clean.
Your
If dirty
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 installed with offsets, the minimum
chimney height is fifteen (15) feet. 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 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.
G. Blower for forced air kit operating - Make
sure that the blower is in the “off” position
when you open the fireplace door for reloading.
IMPORTANT CAUTIONS
A. Do not block the hot air vents to the fireplace
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. Do not burn driftwood 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. Wood
protectors, metallic paper, coal, plastic,
waste, sulphur and/or oil will damage the
fireplace.
G. Do not allow the wood to smoulder or burn
without flame, since this will produce
excessive creosote in the unit
increased particulate emissions.
as well as
Smoke Detectors Recommended
Since there are always several potential sources
of fire in any home, we recommend installing
smoke detectors. If possible, install the smoke
detector in a hallway adjacent to the room
(to reduce the possibility of occasional false
activation from the heat produced by these
appliances). If your local code requires a smoke
detector be installed within the same room, you
must follow the requirements of your local code.
Check with your local building department for
requirements in your area.
Carbon Monoxide Monitor Recommended
Carbon Monoxide Poisoning: Early signs of
carbon monoxide poisoning are similar to the flu
with headaches, dizziness and/or nausea. If you
have these signs, obtain fresh air immediately.
Some people are more affected by carbon monoxide than others, including pregnant women,
people with heart or lung disease or anemia,
those under the influence of alcohol, and those
at high altitudes.
It is against federal regulations to operate
wood heaters in a manner inconsistent with
operating instructions in the manual.
MAINTAINING YOUR FIREPLACE
This wood heater needs periodic inspection
and repair for proper operation. Consult the
owner’s manual for further information. It is
against federal regulations to operate this
wood heater in a manner inconsistent with the
operating in this manual.
Have your product inspected at least once
a year by a qualified service technician to
ensure gaskets, air tubes, baffles, and venting are in good repair to ensure proper performance. Have degraded items replaced
by a qualified service technician.
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.
5
Chimney Maintenance
Regular chimney inspection and maintenance
combined with proper operation will prevent
chimney fires. Keep your chimney clean. Do not
allow more than 1/16” (1.6 mm) creosote build
up in your chimney. The amount of creosote
will 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.
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 side refractory holder. They are
located at the top of the refractory.
2. Lift the front baffle.
3. Slide the back baffle under the front baffle.
You now have access to the chimney.

Dealing With a Chimney Fire
Regular chimney maintenance and inspection
can prevent chimney fires. If you have a 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 extinguisher, baking soda or sand to control the
fire. Do not use water as it may cause a
dangerous steam explosion.
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.
Achieving Clean Burns
Check the exhaust in about 15 to 20 minutes
(see below). Large amounts of smoke indicate
an improper burn setting (either too high or too
low). Adjust and recheck in 5 to 10 minutes.
OK
What does “Well-Seasoned” mean?
When a tree is cut down, the wood is green,
full of sap and moisture. This moisture content
can exceed 80%, which must be reduced to
less than 20%. Wood properly seasoned is
then capable of generating the heat the stove
was designed to provide.
Green wood does not burn easily. Attempting to
burn green wood often results in a lot of smoke
and very little fire. Time is the most important
factor in seasoning wood. Ideally the moisture
content should be reduced to 11-20%.
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
NOTE: The use of a firewood moisture meter is
recommended to ensure the firewood contains
less than 20% moisture.
Seasoning Guide
Softwoods - 6 months to 18 months
Hardwoods - 12 months to 24 months
Logs that are 5” diameter across or larger should
be split in half, three pieces if over 8 inches, and
four pieces when over a foot across. If a tree
has been dead for 2 - 4 years it still needs to
be cut, split, and seasoned for 6 to 24 months
depending on the wood.

DISPOSING OF ASHES
WARNING
Disposal of Ashes: Ashes should
be placed in a steel container
with a tight fitting lid and moved
outdoors immediately. 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 dispersed, they
should be retained in the closed
container until all cinders have
thoroughly cooled.
Whenever ashes get 3 to 4 inches deep in your
firebox, and when the fire has burned down and
cooled, remove excess ashes. Leave an ash bed
approximately 1 inch deep on the firebox bottom
to help maintain a hot charcoal bed.
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.
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 diminish the effectiveness of the refractory. If large
cracks develop, then the refractory should be
replaced. To replace the refractory bricks,
follow these steps:
1. Remove the front refractories
2. Remove the bottom refractory
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.
DOOR INSTALLATION
The door must be installed only when the
installation of the WCT4820WS fireplace is
completed. All you have to do is fit the male
part of the hinge, already on the door, to the
female part, which is on the fireplace.
To remove the door, simply pull the door up
from the hinges.
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 the adjustment screw 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.

GLASS CARE
Glass Replacement
The glass used for the WCT4820WS 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 WCT4820WS fireplace.
Replacement glass should be purchased from a
IHP dealer (see “Replacement Parts”, Page 25).
DO NOT OPERATE THE UNIT WITH CRACKED
OR BROKEN GLASS.
Glass Cleaning
The WCT4820WS fireplace is designed to keep
the glass clean under normal operating conditions. If the WCT4820WS fireplace is operated
continuously with the combustion air controls
closed, the glass will tend to get dirty unless
the 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 IHP
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.
DO NOT USE CHEMICAL GLASS CLEANERS
ON PAINTED SURFACES AS IT MAY CAUSE
THE PAINT TO PEEL.
CAUTION : DO NOT ALLOW WINDOW CLEANER
TO GET IN CONTACT WITH DOOR 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 door from the unit (see Page 7)
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.

FIREPLACE INSTALLATION
Locating The WCT4820WS 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 and chimney.
If possible, you should choose a location where
the chimney will pass through the house without
cutting floor or roof joists (see fireplace dimensions Page 10).
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 in
the appendix. Note the floor construction and
consult your local building code to determine
if additional support is needed.
The WCT4820WS fireplace may be installed
directly on the floor or on a raised base (for
proper guidelines, refer to “Hearth Extension
Requirements”) and a minimum of 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 important factor affecting the chimney performance.
To allow a maximum draft and to reduce wind
turbulence, the chimney must:
• Penetratethehighestpartoftheroof.
• Beinstalledasfaraspossibleofroofoffsets,
trees or any other obstructions that may
cause wind turbulence and back drafts in
the chimney.
• Theleastamountofoffsets(elbows)pos-
sible. NOTE: A maximum of 2 offsets is
allowed.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
Framing, Facing And Mantel
The construction of the framing, facing, and
mantel must be in accordance with the standards and the following illustrations (Figures
7, 8 and 9):
A. Frame the fireplace using 2” x 3” or heavier
lumber.
B. WARNING: Combustible materials
cannot 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) measured 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 9). 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 support
the facing and mantel.
D. WARNING: The fireplace must not be in
contact with any insulation or loose filling material. Cover the insulation with
Drywall panels around the fireplace.
Fireplace
The crack between the fireplace
and the hearth extension must be
sealed with a non-combustible
material such as sand-cement
grout.
Elevated Fireplaces
u Elevated fireplace installations re-
quire a special “Z” Metal Safety Strips
(field provided), in place of the safety
metal strip shown above. The safety
strip should extend the full width of
the fireplace. When more than one
safety strip is used they must overlap
by a minimum of 1”. Hearth extension
of an elevated fireplace must respect
the same minimal dimensions as a
fireplace installed directly on the floor
(Figure 8).

Hearth Extension Requirements
The WCT4820WS fireplace may be installed
directly on a combustible floor. The supplied
safety metal 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 7).
* The safety metal strip must cover the entire
width of the fireplace
The combustible floor in front of the fireplace
must be covered with a non-combustible material (tile, marble, stone, etc). See Figures 7 and 8.
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,
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).
