III. OPERATION
1. General overview
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 MX2
TM
control system (see Figure 17). The MX2
TM
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. Electric Igniter
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.

4.1 Basic Description
The MX2
TM
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
