If you are not sure, ask your dealer for explanations on your heater’s
proper operation.
3. The burn pot of this heater is designed for premium grade wood pellets.
Pellets with too much fines and saw dust must be screened before use.
DO NOT USE WET PELLETS. Refer to the “Fuel Requirements”
section for more information.
4. Oil the circulation fan motor bearings every 6 months. See “Maintenance”
section for more details.
5. Check your local building codes regarding restrictions or installation
requirements. All installations must comply with local building codes.
6. This heater requires a floor protector beneath the heater and extending a
minimum of 6 inches (150mm) in front and beyond each side of the fuel
loading and ash removal openings of the heater. This is to catch any
spillage, which may occur during opening and closing of the doors. See
figure 1 for more information.
7. Use only UL/ULC listed Type PL or Type L venting for the exhaust
system. This heater is designed for use with 3-inch (76 mm) vent pipe.
Avoid long runs and too many bends. It may be necessary to increase the
size of the vent pipe to 4 inch (102 mm) if long runs and too many bends
are unavoidable. See “Venting System” section for more information.
8. Combustion of wood pellet fuel leaves ash in the heater and venting
system. These ashes must be removed from the heater and venting
regularly (approximately once a week, more frequently for high ash
content fuels). See “Maintenance” section for more information. The
entire system must also be cleaned at the start of each heating season. A
yearly inspection of the venting is highly recommended.

Page 5
9. The heater must be turned off and allowed to cool before cleaning. Make
sure there are no hot ashes or embers present. Use a brush and scoop to
clean. Only use vacuum cleaners specifically designed for use with hot
ashes. Place all ashes in a sealed metal container with a tight fitting lid.
10. Store all pellet fuel at a safe distance (at least 36 inches / 1 meter) away
from the heater and in a sealed metal container. DO NOT place the fuel
within the installation clearances of the stove or within the space needed
for ash removal and start up.
11. This heater is POWER VENTED. The vent pipes have positive pressure
during operation. It is IMPERATIVE that all joints in the venting system
be SEALED to prevent any leakage of exhaust gases inside the house.
All joints must be sealed using high temperature silicone sealer (RTV).
Aluminum tape is not an adequate sealant.
12. Use of outside combustion air is highly recommended and is mandatory
in mobile home installations. Connect the air intake of the heater to the
exterior of the building with a noncombustible metal pipe with a
minimum diameter of 2 inches (50 mm) (Use APR Part No AK100). Use
of plastic pipe is not permitted.

2. ElectricalRequirements
1. This heater is an electrical appliance. The NorthAmerican versions of
this appliance require 120 Volts, 60 cycle and 3 Amps of electrical
power. The European versions of this appliance require 230 Volts, 50
cycles and 2Amps of electrical power. All heaters with an electric
igniter require an additional 300 watts of electrical power during the start
up sequence.
2. The heater comes with a 5 ft. (1.5 M) long, grounded, electrical cord
suitable to plug into any standard residential electrical outlet. The
electrical outlet must be grounded.
3. When installed in mobile home, the heater must be grounded to the steel
chassis of the home (unless this is not required by local code).
3. Fuel Requirements
3.1 Physical Properties
Your heater is very sensitive to fuel quality. Every effort should be made to use only the
best pellet fuel available in your area. This heater is designed for premium grade, 1/4
inch (6.35 mm) or 5/16” (7.94mm) diameter wood pellets only. The following should
assist you in selecting and using proper fuel.
If you find your fuel has too much fines and saw dust, the fuel may be screened before
use. DO NOT USE WET PELLETS under any circumstance. Longer fuel may cause
bridging of the auger and result in erratic feeding or jamming. Fines, binders, ash,
moisture will all cause your heater to plug up and not burn efficiently. “Poor” fuels
require more frequent cleaning; the ashtray must be emptied and the burn pot must be
cleaned on a weekly/possibly daily basis. Please refer to the “Maintenance” section for
further instructions on cleaning your heater.
3.2 Fuel Storage
All pellet fuel should be stored in a clean dry place and at a safe distance (at least 36
inches / 1 meter) away from the heater. DO NOT place the fuel within the installation
clearances of the heater or within the space needed for ash removal or starting of the
heater.
Burning any fuel other than wood pellets as described above
will void your heater’s warranty and may void any insurance.

6. Venting System
6.1 ExhaustVent Pipe Requirements
Your KOZI pellet heater works under negative pressure (vacuum). The exhaust fan of
your stove pulls air from the air intake, through the stove and pushes it out the venting.
As this air passes through the burn pot it is used to burn the pellets. Proper vent pipe
sizing is very important to the proper operation of your stove. A proper size ULC/UL
listed type PL or L venting should be used to provide the least resistance for movement of
the combustion air.

Page 12
Your KOZI pellet heater is certified for 3 and 4 inch exhaust venting. 3 inch venting is
normally sufficient for most direct vent installations. Installations with several elbows,
long horizontal and/or vertical runs may add too much resistance to air flow and may
create burn problems. The use of 4 inch venting in these types of installations will reduce
the possibility of burn problems. A simple technique called ‘EQUIVALENT VENT
LENGTH (EVL)’ can be used to determine whether 3 or 4 inch vent pipe should be used.
To calculate EVL use the following formula:
for each 90° Elbow or T fitting = add 5 EVL
for each 45° Elbow = add 3 EVL
for each Horizontal run of vent = add 1 EVL per foot of horizontal venting
for each Vertical run of vent = add 1/2 EVL per foot of vertical venting
CAUTION: EVL CANNOT EXCEED 25 ft. (7.6 meters). Installations
using an EVL exceeding 25 ft. (7.6 meters) are not permitted.
If in doubt, use 4” venting. This will reduce the possibility of future burn problems.
DO NOT CONNECT THIS HEATER TO A CHIMNEY
FLUE SERVING ANOTHER APPLIANCE
DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST
VENTING SYSTEM OF THIS HEATER
DO NOT USE MAKESHIFT MATERIALS OR MAKE COMPROMISES
IN THE INSTALLATION. IT IS A FIRE HAZARD.
YOU MUST USE APPROPRIATE 4” VENTING IF:
The EVL is 7 or moreAND you are at or above an altitude of 3000 ft.
OR
The EVL is 15 or more
OR
Your heater is an Insert

Page 13
The vent pipes are on the exhaust side of the exhaust fan and are under pressure. Care
must be taken to ensure that all the joints are completely sealed to prevent any leakage of
exhaust fumes and smoke into the house. If you smell smoke, the venting has not been
properly sealed. Use only high temperature RTV silicone for sealing. Aluminum tape is
not considered an adequate sealant. At least 3 screws are needed for securing all vent pipe
joints.
The venting of this heater is not allowed to pass through any closets, concealed spaces,
floors, ceilings or attic spaces. If the venting must go through a wall or combustible
partition, the installation must conform to the Installation Code for Solid Fuel Burning
Appliance and Equipment CAN / CSA -B365. For more detailed venting information,
please refer to your venting manufacturer’s instructions.
6.2 Exhaust Vent Termination Requirements
1. It is highly recommended that the venting include a minimum 3’ vertical
rise before termination. This will help prevent any odor of smoke in the
house during a power failure.
2. The exhaust vent must terminate into an open space. Under no circum-
stances is the vent allowed to terminate into closed or semi-closed
spaces. Venting into a garage, under a sun deck, porch or any other
space where the concentration of fumes may occur is prohibited.
3. The exhaust vent must be at least:
* 4 feet (1.2 m) below
* 4 feet (1.2 m) horizontally from
* 1 foot (0.3m) above
any opening in the building such as doors, windows, ventilation air
intakes, etc.
4. The exhaust vent opening must be a minimum of:
* 12 inches (0.3m) from the ground
* 24 inches (0.61m) from any combustible surface i.e. fence, plant, etc.
* 7 feet (2.1 m) from any public walkway
5. The exhaust air is EXTREMELY HOT. Caution must be taken to avoid
contact with children, people, plants, animals, or any other object that
may be affected by heat. It is recommended to use a vertical pipe to
discharge the hot air at a safe elevation.
6. Vertical installations must have an approved vertical vent cap and
horizontal installations must have an approved horizontal vent cap.
Areas where severe wind conditions exist and vent caps are exposed to
unprotected open areas additional protection (especially in horizontal
installations) must be provided.

Page 14
6.3 CombustionAir Intake Requirements
There are 2 methods of supplying the heater with combustion air. They are as follows:
1. Room Air: Conventional homes may use room air for combustion. Where
room air is used, the exhaust pipe must incorporates a minimum 3’
vertical section immediately adjoining the heater. It is highly recom-
mended that the total exhaust vertical rise be longer than the total
horizontal run and that the majority of the vertical rise be as close to the
heater as possible..
2. Outside Air: All installations can be connected to the exterior of the
building using a noncombustible metal pipe, with a minimum 2 inch
(50mm) internal diameter or by using APR Part No: AK100 (Air Intake
Kit). A larger diameter air intake pipe may be required if the length of
intake exceeds 3’ (1 meter) or has several bends. Use of plastic pipes are
not permitted.
In some installations, outdoor combustion air may be needed to ensure proper perfor-
mance. If your heater burns poorly, experiences roll-out or back-drafts, outside combus-
tion air may be required.
The following restrictions apply to any and all installations:
1. Use of plastic pipes is not permitted under any circumstance.
2. The combustion air intake must terminate into a vented space, i.e. outside,
vented attic, vented crawl space. This heater cannot draw air from a
closed space such as a closed garage, airtight crawl space or any other
sealed room.
3. The elevation of the combustion air intake must be below the exhaust
vent. An elbow may be used to lower the air intake point below that of
the exhaust vent.
4. Excessive lengths and elbows on the air intake pipe will cause airflow
restrictions. A minimum of 2 inch (50 mm) or larger venting should be
used for lengths exceeding 3’ (1 meter). Increase the venting size as
needed.
5. When installing a KOZI KSH 120 in a garage/work shop, the combustion
air must be taken from the outside or else the unit must be elevated a
minimum of 15 inches above floor level if inside combustion air is
desired.

KOZI PelletInsertAdditionalConsiderations
The KOZI Pellet Insert can be installed in either a masonry or listed factory built
fireplace or an alcove. The minimum opening for masonry or listed factory built fireplace
is pictured below. Please see the “Clearance to Combustibles” section for information on
installing an insert in an alcove.
Figure 13. Minimum Fireplace opening for the KOZI pellet insert.
7.1 KOZI Pellet InsertAdditional Requirements
When installing and removing a KOZI pellet insert in a masonry or listed factory built
fireplace, the following requirements must be met:
1. The room in which the insert is installed must be sealed from the exterior.
This can be done by sealing the chimney cavity to the venting either at
the terminal (see figure 12A) or at the chimney damper (see figure 12B).
2. When installing the insert and its surround into a masonry or listed
factory built fireplace, the air flow of the existing fireplace must not be
altered. Make sure no louvers, cooling air or outlet ports are blocked.
3. When installing an insert, a full height listed chimney liner must be
attached to both the insert flue collar and to the chimney top as shown in
figure 12A or a partial chimney liner may be attached to the insert flue
collar and extending a minimum of 6 inches into the chimney cavity as
shown in figure 12B. The chimney liner must be properly sealed to the
seal plate using high temperature (RTV) silicone. This chimney liner
must be stainless steel.
4. A permanent metal tag must be attached to the back of the fireplace. The
metal tag will state the following “After removal of this pellet insert, the
fireplace must be restored to its original state for safe use”.
5. The fireplace can NOT be altered in any way except for the following
situations:
A. For installation of a chimney liner, the chimney damper may be
removed.
B. External trim pieces of a fireplace can be removed only if they do
not affect the operation of the fireplace upon removal and they can
be reassembled when the insert is removed.

Page 16
C. Where a L or PL type venting is used to vent the insert through a
masonry fireplace (see “Typical installation Configurations”
section, figure 10A), a hole may be cut through the fireplace to
accommodate the vent pipe. This hole must be properly repaired
upon removal of the insert.
Figure 14. KOZI pellet insert
surround
7.3 KOZI Pellet Insert Installation
Please follow the following steps when installing a KOZI pellet insert:
1. Verify that the fireplace opening meets the insert’s minimum require-
ments.
Working from the exterior of the building:
2. Attach and seal the exhaust venting to the terminal using sheet metal
screws and high temperature (RTV) silicone sealant.
3. Insert the venting into the existing chimney and secure the terminal to the
chimney. Ensure that the venting and chimney are properly sealed.
4. If outside combustion air is being used, install the air intake as necessary.
Working from the interior of the building:
5. Verify that an electrical outlet is available for the pellet insert. If not,
have one installed.
6. Place the insert part way into the opening.
7. Attach and seal the free end of the exhaust venting to the pellet insert
using sheet metal screws and high temperature (RTV) silicone sealant.
8. If the top of the chimney was not sealed to the vent terminal in step 3,
seal the existing chimney damper to the new pellet venting to prevent
drafts to and from the home.
9. Plug the power cord into the electrical outlet.
10. Assemble the surround (if not previously assembled) and slide it on the
insert (see the “Surround Assembly” section).
11. Push the insert into the cavity until the surround touches the existing
fireplace.
7.2 SurroundAssembly
The KOZI pellet insert surround can be seen in
Figure 14. The surround comes in 3 separate
pieces and needs to be assembled before being
attached to the heater. Layout the top and sides
of the surround on the floor as shown in figure
14. Verify that each side piece mounting holes
are aligned with the top piece mounting holes.
Using the supplied 1/4” bolts, secure the side
pieces to the top. Your surround is now ready to
mount to the insert.

Page 17
7.4 KOZI Pellet Insert Removal
There may be some situations where the KOZI pellet insert needs to be removed from
the fireplace; venting may need to be resealed, regular maintenance performed, etc....
Removal of the KOZI pellet insert heater from a fireplace is the reverse of installation
with the following exceptions: make sure the insert is not operating, has had sufficient
time to cool down and that power to the insert has been removed. Now you can pull the
insert all the way out and do the maintenance on the insert or fireplace.
7.5 Operation and Maintenance
Please refer to the “Heater Operation” section of this manual for complete instructions on
how to operate your KOZI pellet insert. Please note that fuel loading on the insert is
done through the small opening on the top of the stove. To load fuel into the insert,
remove the cover plate from the top of the insert, pour fuel into the opening and replace
the cover plate. DO NOT place hands inside the opening to the hopper. There are
moving parts in the hopper which can cause bodily harm.
Maintaining the KOZI pellet insert is the same as maintaining a free standing pellet
stove. Please read the “Maintenance” section for instructions on cleaning your insert,
venting and other maintenance precautions.
8. MobileHomeAdditionalInstallationRequirements
8.1 Typical Mobile Home Installation Configuration
The following figures describe some typical installations for mobile homes. Variations of
these are possible. Common sense, safety and compliance with local building codes must
be respected in any variation.
Figure 15A. Mobile home installation
through wall; interior rise Figure 15B. Mobile home installation
through wall; exterior rise

Page 18
8.2 Recommendations for Mobile Home Installation
1. Make sure there is an effective vapor barrier where the venting penetrates
to the outside of the mobile home. Seal all openings in the vapor barrier
as required.
2. Make sure the mobile home has adequate ventilation. Your stove is a
solid fuel burning appliance. As such, there is a possibility of smoke
entering the room. By making sure the mobile home is adequately
vented, you reduce the chances of smoke remaining in the mobile home.
3. Make sure the venting is properly installed and sealed. Leaking vent
pipes may set off smoke detectors in the mobile home. Also, some fuels
may produce carbon monoxide which, in large amounts, can be fatal.
Make sure the venting is installed properly to prevent leakage of carbon
monoxide into the mobile home.
4. If parts become damaged or need to be replaced, please contact your local
dealer or visit WWW.KOZISTOVES.COM. Do NOT replace parts with
any other parts not specified by your local dealer or manufacturer.
8.3 Mobile Home CombustionAir Intake Requirements
All mobile home installations MUST use combustion air from the outside. This heater
must be connected to the exterior of the mobile home using a noncombustible metal pipe,
with a minimum 2 inch (50 mm) diameter. APR Industries Ltd. part # AK100 (Air Intake
Kit) can be used for this purpose. Use of plastic pipes are not permitted. Please read
the “Combustion Air Intake Requirements” section for more information.
(although this installation is permitted, a 3’ (1
m) vertical rise is strongly recommended)
Figure 15D. Mobile home installa-
tion through wall
Figure 15C. Mobile home installation
through roof

Page 19
8.4 ExhaustVent Requirements
Venting a KOZI pellet burner for a mobile home is similar to that of a conventional
home. Please refer to the “Typical Mobile Home Installation Configuration” section for
typical venting configurations the “Venting System” for vent termination and other
requirements. It is highly recommended that 3 ft. minimum of vertical venting be used
(as shown in Figure 15A and Figure 15B). This will reduce the chance of smoke spillage
into the mobile home in case of a power failure.
8.5 Other Mobile Home Installation Requirements
1. The heater must be securely anchored to the floor of the mobile home.
There are 2 holes located on the base of the stove near the back (4 on
KSH models). Use two 1/4” lag bolts (not supplied) in these holes to
anchor the stove to the floor of the mobile home. For KSH models, the
side panels will need to be opened to access these holes.
2. There must be a noncombustible floor protector placed underneath the
heater and extending a minimum of 6” (150 mm) in front of the heater
(see “Clearance to Combustibles” section for more information).
3. This heater can not be installed in any sleeping room of the mobile home.
4. The heater must be grounded to the steel chassis of the mobile home
(unless this is not required by local code).
5. The installation must be in accordance with the Manufactured Home and
Safety Standard (HUD), CFR 3280, Part 24
CAUTION: THE STRUCTURAL INTEGRITY OF THE FLOOR, WALL AND
ROOF OF THE MOBILE HOME MUST BE MAINTAINED.

III. OPERATION
1. Generaloverview
The first step in understanding your new KOZI heater is to
familiarize yourself with its operation. Your heater has 3 main
systems: Feed, Combustion and Circulation. These 3 systems
work together to produce enough heat for your room. The feed
system uses an auger to “feed” the pellet fuel into the burn pot.
The combustion system provides the air for the fuel to burn and
pushes the “smoke” outside through the vent pipes. The circula-
tion system takes cold air from the room and pushes it through the
heat exchanger where it will warm up and flow back into the room
as hot air. These 3 main systems are all control by the MX2TM
control system (see Figure 17). The MX2TM control system will be
described in more detail later.
2. Circulation fan override: If your pellet heater begins to overheat, this
safety device switches the circulation fan to the highest possible setting
to try to cool your heater down to a safe temperature.
3. High limit/manual reset thermal disk: If the Circulation fan override fails
to cool the heater down fast enough, this thermal disk will turn the feed
off . This final safety device guards against your heater overheating. If
this thermal disk trips, the right side panel will need to be opened and the
thermal disk reset. See “Maintenance” and “Troubleshooting” sections
for more information.
4. Hopper lid switch: This safety device stops the auger from turning when
the hopper lid is opened, preventing any bodily harm.
3. ElectricIgniter
Some models of KOZI pellet heaters are factory equipped with an electric igniter. On all
other models, the electric igniter is optional and can be purchased/installed at any time.
The electric igniter is a convenient way of lighting the fire in your heater without the use
of lighter gels or starter fuels. Ask your dealer if an electric igniter is right for you.

MX2TM Control
4.1 Basic Description
The MX2TM control is a digital control that uses a computer to control the operation of
your heater. You should be familiar with all of the buttons on this control before using
your heater. Each button and their function are described here.
4.2 “AUTO,HIGH/LOW,MANUAL” Switch
Your pellet heater is capable of operating in 3 different modes; “AUTO”, “HIGH/LOW”
and “MANUAL”. Figure 18 will help you determine which mode is suitable for use in

1. Pressure switch: This safety device is used to turn the feed off if pressure
is lost in the stove.
Please note that if your door is open or your ash gates/tray are
not properly sealed, your pellet heater will not feed
