I. Installation And Operation Manual
This heater is suitable for both mobile home and conventional home installations. Read
all instructions carefully before starting installation. Save this manual for future refer-
ence.
1. Preamble : Instructions for Safe Installation and Operation.
1. Read these instructions carefully. Failure to follow them could cause
malfunction or damage to the heater, property damage, bodily injury
and even death.
2. Familiarize yourself with the operation of the heater. (See “Heater
Operation” section). If you are not sure, ask your dealer for explana-
tions on your heater’s 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. High ash content fuel will clog the
burn pot holes and, as a result, the burn pot will require frequent
cleaning.
4. Oil the motor bearings every 6 months. See “Maintenance” section for
more details.
5. Check your local building codes. All installations must comply with
their rulings.
6. This heater requires a minimum 6 inch (150 mm) floor protector in
front of the heater. This is to catch any spillage that may occur during
opening and closing of the door.
7. Use only UL/ULC listed Type Pl or Type L venting for the exhaust
system. The heater is designed for use with 3 inch (76 mm) vent pipe.
Avoid using long runs and too many bends. It may be necessary to
increase the size of venting to 4 inches (102 mm) if long runs and too
many bends are unavoidable. See “Venting System” for more details.
8. Combustion of wood pellet fuel deposits ashes in the heater and venting
system. These ashes must be removed from the heater regularily
(apporximately once a week). If a high ash content fuel is used,
cleaning must be done on a more frequent basis. 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 in the burn pot, ash tray or
combustion chamber. Use a brush and scoop to clean. DO NOT USE
A VACUUM CLEANER.
10. 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).
11. Store pellet fuel at a safe distance (at least 36 inches/1 meter) away
from the heater.
12. Use of outside combustion air is MANDATORY (unless an APR Part
No CV100 check valve is used). Connect the air intake of the heater to
the exterior of the building with a non-combustible metal pipe with a
minimum diameter of 2 inches (50 mm). Use of plastic pipe is not
permitted.
13. Follow this manual carefully for proper installation. If you are
uncertain, call your dealer. Most of the dealers have qualified and
trained installers. We highly recommend the use of their services.

3. For a pictorial view of clearances to combustibles, see the safety test
label attached to your stove. A copy of this label is provided here.

Page 7
INSTALLATION COMMENT: We recommend that sufficient space be
provided (minimum 20 inches/500 mm) on each side of the heater to ser-
vice the equipment area. In case this is not possible, provisions must be
made to pull out the heater for service.
FLOOR PROTECTION: A non-combustible material, extending a mini-
mum of 6 inches (150 mm) in front of the heater is required.
3. Electrical Requirements
1. This heater is an electrical appliance and requires 120 Volts, 60 cycle, 3
Amp of electrical power.
2. This 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 a mobile home, the heater must be grounded to the
steel chassis of the home (unless this is not required by local code).
4. Venting System
Before proceeding with the installation, the following sections should be reviewed:
Section 4 : Venting System
Section 5 : Location of the Heater
Section 6 : Typical Installation Configurations
4.1 Exhaust Vent Pipe Requirements
KOZI pellet stoves have a negative pressure burn chamber. A high-pressure, radial
blade fan pulls the air out of the burn chamber creating negative pressure (vacuum)
inside the burn chamber. The air from outside the stove then rushes through the intake
air tube, burn pot stand and burn pot to fill this vacuum. As this air passes through the
burn pot it is used to burn the pellets. 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.
This KOZI pellet burner is certified for 3 inch exhaust venting. 3 inch venting is quite
sufficient for most direct vent installations. However, installations with several elbows,
long horizontal and/or vertical runs may add excessive resistance against the flow of air,
which reduces the volume of air movement and creates burn problems. Use of 4 inch
venting will reduce this resistance. A simple technique called ‘EQUIVALENT VENT
LENGTH (EVL)’ can be used to determine whether 3 or 4 inch vent pipe should be used.

Page 8
To calculate EVL use 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
YOU MUST USE 4” STAINLESS STEEL RIGID OR FLEXIBLE VENT PIPE IF:
The EVL is 7 or more AND your are at or above an altitude of 3000 ft.
OR
The EVL is 15 or more
OR
Your unit is an Insert
DO NOT USE MAKESHIFT MATERIALS OR COMPRO-
MISES IN THE INSTALLATION. IT IS A FIRE HAZARD.
Exhaust vent pipes are located on the exhaust side of the exhaust fan and are under
positive pressure. Care must be taken to ensure that all joints are completely sealed to
prevent any leakage of exhaust fumes into the house. If you smell smoke, the venting
has not been properly sealed. Use only high temperature RTV silicone for sealing.
4.2 Combustion Air Intake Requirements
A. It is mandatory to use outside air for combustion in ALL mobile or
manufactured home installations.
B. Conventional homes may use APR Part No: CV100 check valve in
order to use internal combustion air. If a check valve is not used, the
air intake of this heater must be connected to the exterior of the
building using a non-combustible metal pipe, with a minimum 2 inch
(50mm) diameter. Use of plastic pipes are not permitted.
C. The combustion air intake must terminate into a vented space, i.e.
outside, vented attic, or vented crawl space. This heater CAN NOT
draw air from a closed space such as a closed garage, airtight crawl
space or any other sealed room.
D. 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.
F. Excessive lengths and elbows on the air intake pipe will cause airflow
restrictions. A minimum of 2 inch, or larger, venting should be used
for longer lengths. Increase the venting size as needed.

Page 9
4.3 Exhaust Vent Termination Requirements
A. The exhaust vent must terminate into an open space. Under no
circumstances is the vent allowed to terminate into closed or semi-
closed spaces. Venting into a garage, under a sundeck, porch or any
other space where the concentration of fumes may occur is prohibited.
B. The exhaust vent must be at least:
* 4 feet (1.2 m) below
* 4 feet (1.2 m) horizontally from, and
* 1 foot (0.30m) above
any opening in the building such as door, window or ventilation air
intake, etc.
C. Exhaust vent opening must be minimum of:
* 1 foot (0.3m) from the ground
* 24 inches (0.61m) from any combustible surface, i.e. fences, plants,
combustible objects, etc.
* 7 feet (2.1 m) from any public walkway.
D. Exhaust air is EXTREMELY HOT. Caution must be taken to avoid
contact with children, people, plants, animals or any other object that
will be affected by heat. It is recommended to use a vertical pipe to
discharge the hot air at a safe elevation.
E. Exhaust venting must be installed in accordance to the instructions
provided by your pellet vent manufacturer.
F. The vent terminal must have an end cap to protect against down draft
and back draft created by severe wind conditions.
5. Location of the Heater
A. This heater is NOT approved for bedroom installation.
B. If installed in a mobile home, the heater must be anchored to the floor.

Page 10
C. When installed in a conventional or a mobile home, check for:
a. Clearance to combustibles. d. Power within 6 feet (1.8m)
b. Sufficient room to service the unit. e. Access for exhaust venting.
c. Access for outside combustion air. f. EVL not exceeding 25ft (7.6m)
See Exhaust Venting Require-
ments.

II. Understanding Your Pellet Burning Heater
1. Component Description
1.1 General Overview
The first step in understanding your new KOZI heater is to familiarize yourself with it’s
operation. Your heater has 3 main systems: Combustion, Circulation and Feed. The
combustion system includes the air intake, burn pot, exhaust fan and exhaust venting.
The circulation system consists of a circulation fan, fan speed control and heat ex-
changer. The feed system is made up of an auger motor and various safety devices.
Each part of these systems will be described below in detail. A description of the
operation and the controls for your stove is provided in the section entitled “Heater
Operation”.

Page 13
1.2 Exhaust Fan
The purpose of the exhaust fan is to remove the smoke from the combustion chamber.
The exhaust fan sucks air from the air intake, through the burn pot and heat exchanger
and pushes it through the venting. This fan is a fixed feed fan which is ON whenever the
heater starts and remains on until the stove is cool. THIS FAN CANNOT BE TURNED
OFF MANUALLY. Failure of this fan will result in a complete system shut down.
1.3 Burn Pot
The burn pot is the receptacle in which the pellet fuel is burned. This portion of the
stove requires frequent cleaning since it controls the efficiency of the combustion
process. It is recommended that the burn pot be cleaned every time the hopper is filled
and thoroughly scraped periodically.
1.4 Circulation Fan
The purpose of the circulation fan is to circulate the unheated room air though the heat
exchanger. The circulation fan speed can be controlled by the fan speed control
(described below) but cannot be shut off completely. The control system has a built in
safety that allows it to override the fan speed control in the event that the heater over-
heats. As your unit begins to overheat, the circulation fan will come on high to remove
some of the excess heat. As your unit cools, the circulation fan will return to it’s original
setting. If the circulation fan cannot remove the heat fast enough, a second safety, the
high temperature manual reset disk, will shut the feed mechanism off.
1.5 Troubleshooting Module Status Lights
Your unit is equipped with 3 status lights. Each light indicates a different safety device.
Together, these lights are intended to keep you informed as to what is happening in the
feed system. The top light indicates the status of the auger cycle timer, the middle light
indicates the high temperature manual reset thermal disk and the bottom light indicates
the pressure switch. In normal operation, all 3 lights will be blinking ON and OFF in
proportion to the feed control setting (see “Heater Operation”). Should any problem
arise in the feed system, some or all of the lights will either go out or be blinking
BRIGHT - DIM. Should this occur, please refer to the “Troubleshooting” section.
1.6 Auger Cycle Timer
In conjunction with the feed control, the auger cycle timer controls the feed rate. This is
achieved by turning the auger motor on and off. Failure of this component will result in
a troubleshooting light change. See “Troubleshooting” section for more details.
1.7 High Temperature Manual Reset Thermal Disk
The manual reset thermal disk is a high temperature safety switch. If the heater should
reach an unusually high temperature (due to overheating caused by power outage or
circulation fan failure), this switch will shut the feed system off. The exhaust and
circulation fans will continue removing heat until the unit is at room temperature.

Page 14
Once this switch has been tripped, the control system will not allow any more fuel to
feed into the burn pot until it has been manually reset. DO NOT RESET THIS UNIT
UNTIL THE CAUSE HAS BEEN FOUND AND REPAIRED. Failure of this compo-
nent will result in a status light change. See “Troubleshooting” section for more details.
1.8 Pressure Switch.
The pressure switch is a safety device that senses whether or not the exhaust fan is
functioning properly. Failure of this component will also result in a status light change.
See “Troubleshooting” section for more details
2. Heater Operation
In order to use your stove, you should be familiar with the 4 controls of your heater: Fan
Speed, Feed Rate, Damper and Start button. These 4 controls will allow you to adjust
and operate your stove safely and efficiently. The location and method of adjustment for
each of these is described below.
2.1 Circulation Fan Speed Control
The fan speed control is located on the top center of
the control panel (see diagram). Turning this knob
counter-clockwise temporarily turns the circulation
fan off. Rotating clockwise decreases the speed of
the circulation fan from High to Low. It is NOT
recommended to leave this knob in the OFF
position. When left in the OFF position, the heater
becomes over heated and the control circuit
automatically overrides this switch and puts the
circulation fan on high speed.
2.2 Feed Control Knob
The feed control is a round knob located at the bottom of the control panel (see diagram).
Turning the knob in the counter-clockwise direction will turn the feed off. As the knob
is turned clockwise, the feed rate into the burn pot is increased, resulting in a bigger fire.
2.3 Damper Control
The damper control rod is located on the left side of the stove. This rod controls the
amount of air passing through the burn pot. By pushing the control rod in, you reduce
the amount of air passing through the burn pot. By pulling the rod out, you will increase
the amount of air passing through the burn pot.

Page 15
2.4 Start Button
The start button is located in the middle of the control panel (see diagram). Pushing the
start button is the first step in starting the heater. The heater will now run in manual
operation mode for 15 minutes. The heater will switch to the automatic mode only if the
heater reaches a preset temperature. If this temperature is not reached within 15 minutes
the unit will shut off. To allow the unit to run for another 15 minutes, simply press the
start button again.
2.5 Starting your Heater for the First Time
Once your heater is properly installed, complete the following steps to light it for the first
time:
1. Fill the hopper with pellet fuel.
2. Turn the feed control knob clockwise to high.
3. Press the start button. The exhaust and circulation fan should come on
and all 3 status lights should begin to blink.
4. Monitor the burn pot (located inside the burn chamber, see “Stove
Cross Section” diagram for exact location.). Once pellet fuel begins to
drop into the burn pot, turn the feed control knob to OFF, (counter
clockwise until it “clicks”) and allow the unit to stop running. Do not
light the pellet fuel at this time. If the unit stops and no fuel has been
fed into the burn pot, repeat steps 1 through 4.
You are now ready to light the stove for the first time.
2.6 Starting (lighting) your Heater
To start your heater, complete the follow steps:
1. Ensure there is adequate fuel in the hopper.
2. Turn the fuel feed knob to desired setting. (If in doubt, adjust to 12
o’clock setting)
3. Adjust damper to approximate setting. (If in doubt, pull open to
approximately 3/4" - 2 cm)
4. If equipped with electric start, proceed to step 9.
5. Open the burn chamber door and place a handful of fuel in the burn
pot. The burn pot should be approximately 1/4 full with wood pellets.
6. Pour lighter gel on pellets in the burn pot.
7. Ignite lighter gel with barbecue lighter and allow the pellets to catch
fire. DO NOT ATTEMPT TO IGNITE HOPPER FUEL ON FIRE.
8 Close the combustion chamber door.
9. Press the start button. The following should happen :
a. The exhaust fan will start.
b. The circulation fan will start at the fan speed control setting.

Page 16
c. The feed system begins to feed. The auger and troubleshooting
lights should begin to blink.
d. If electric start is installed, it will come on.
e. On electric start models, the flame should appear within 5 to 10
minutes.
10. Allow the flame to stabilize for 15 minutes.
11. Adjust the feed and damper as necessary. (see “Adjusting your
Heater” section)
12. If the unit shuts off and there is still a flame, press the start button
again.
2.7 Stopping your Heater
To stop your heater, turn the fuel feed control knob counter-clockwise to the OFF
position. This will cause the feed system to stop (troubleshooting lights will stop
blinking) and the flame should die out within 5 minutes. The exhaust fan and circulation
fan will continue to run until you heater is cold (approximately 30 minutes). DO NOT
turn off electrical power to stop the heater, as this will result in your unit overheating.
2.8 Adjusting your Heater
The Heater will not operate properly if either the ash door or glass door is not properly
closed OR if the wrong size of venting is used. It is equally important that you use good
quality, wood pellet fuel. A poor quality fuel will create poor and unsatisfactory
operating conditions.
To increase the heat output of the your stove, slightly increase the feed rate by turning
the feed control knob clockwise. In a few minutes the flame size will increase. If the
flames are darkish with black tips, open the exhaust damper slightly and allow the flame
to stabilize. Repeat the procedure if more heat is desired. Flames that are too large mean
the feed rate is too high for the amount of combustion air present. Reduce the feed rate
slightly or increase the amount of combustion air. In few minutes the size of the flame
will reduce. If the size of the flame is fluctuating between feed drops, this indicates that
the amount of combustion air is too much for the amount of feed. In this case, close the
air damper slightly and once again, allow the flame to stabilize. When reducing heat
output, slightly close the air damper at the same time as you are reducing the feed rate. If
the air damper is open too far, there is a chance of extinguishing the fire. Some fuels
have a tendency to leave ash and clinker deposits in the bottom of the burn pot. Use a
poker to remove the clinkers if the heater is operating OR cool off the heater and clean
the burn pot.
If you find that the circulation fan is constantly running on high although your fan speed
setting is much lower, your unit is overheating. Reduce the feed rate as described above.

Page 17
III. Maintenance
During operation, your heater produces a lot of “FLY” ash. The ash will deposit inside
the heaters’ air passages and must be removed on a regular basis. A medium size brush
is ideal for this purpose. Make sure the heater is cool and there are no embers present in
the burn pot, ashtray or combustion chamber. Also, make sure there is no power to the
unit by unplugging the power cord from the power source. Your heater can then be
cleaned in the following manner:
1. Pull and push the cleaning rod, which is located in the center, above the
door. This will remove the ash deposits on the heat exchanger tubes.
The removed ash will fall on the top heat shield, located in the burn
chamber.
2. Lift the top heat shield and remove it carefully as there may be a
significant amount of ash on it. Dump the ashes into the burn
chamber.
3. Brush the top heat shield clean and remove it from the heater.
4. Remove the burn pot and burn pot stand and clean them thoroughly.
5. Using a brush, clean the walls and floor of the burn chamber. Dump all
of the ash into the ashtray. Remove the ashtray and dispose off the
ashes in safe manner. If ashes are stored in a container, make sure the
lid is secure. DO NOT place the container on combustible surfaces.
6. Once a year, at the start of the heating season, clean the heater and all
of the venting pipes. Check for any blockage in the intake and exhaust
pipes.
7. Replace burn pot stand, burn pot and top heat shield to their original
positions.
8. Clean the glass with a mild glass cleaner.
9. Inspect condition of the door gasket periodically and replace as
necessary.
10. Open the right hand side panel and oil the circulation fan motor
bearings. Use a light oil such as sewing machine oil. The 2 oil ports
are located on the top of the motor, one near the end and one near the
fan housing. There may be a rubber plug in one or both of these oil
ports. This plug must be removed prior to oiling.

Page 18
IV. Trouble Shooting Guide
The KOZI model 100 is equipped with a troubleshooting light module, located at the
back, bottom right hand corner of the stove. This module consists of a set of three red
lights. Under normal working conditions, while the stove is operating, all three lights are
BLINKING (on and off). The rate of blinking is in proportion to the fuel feed rate. The
higher the feed rate, the faster the lights will blink. Any time the sensors detect abnormal
working conditions, they will turn OFF the fuel feed system to prevent any further
damage and turn OFF or PULSE (bright - dim) the lights to indicate where the fault has
occurred.
Note: For safety, contact a qualified serviceman for all repair work.
