ELECTRICAL COMPONENT FUNCTIONS
The following is a list of electrical components and their functions on the ENVIROFIRE EF-IIi pellet stove.
1. CONVECTION FAN CONTROLLER
This controller is responsible for varying the speed of the convection blower. The stove has a fan control-over-
ride. Should the convection blower be set on low and the Dial-A-Fire set on high, the convection blower will by-
pass the fan controller and go to high. This will cool the stove until control is given back to the fan controller. To
eliminate possible cycling of the convection blower, turn up the fan speed proportionately to the Dial-A-Fire.
2. STOVE TEMPERATURE LIGHT
This light is designed to tell the operator when the units exhaust temperature is above 120°F (49°C). The
auto/manual switch should be put in the auto position when the green light comes “ON”.
3. AUTO/MANUAL SWITCH
In the MANUAL position this switch bypasses the 120°F (49°C) temperature sensor. This will allow you to start
and operate the stove when it is cold. In the AUTO position, the 120°F (49°C) sensor has control of the stove.
This allows the stove to shut off if the fire goes out.
4. DIAL-A-FIRE (HEAT OUTPUT CONTROL)
This unit is responsible for controlling the timing of the auger motor. When turned clockwise, it will cause the OFF
time between auger pulses to shorten, resulting in more heat output and pellet consumption. Turn the knob
counter-clockwise and the reverse will happen. When it is turned fully counter-clockwise past the “click”, the auger
will stop.
5. CONVECTION BLOWER
This blower fan (mounted on right hand side of the stove) draws room air from the back of the stove and passes
the air through the heat exchanger tubes and back into the room. This sealed system keeps the room air separate
from the combustion air. The convection fan controller controls this fan’s speed.
6. COMBUSTION/EXHAUST BLOWER
This constant fan (mounted on the left side of the stove) is responsible for drawing the outside fresh air into the
combustion chamber for burning. The hot air then continues to be drawn over the heat exchanger tubes and into
the exhaust channel. It is then pushed out through the exhaust system.
7. AUGER MOTOR AND AUGER
This 1-rpm auger motor is responsible for turning the auger, which in turn transports pellets to be dropped into the
burn pot. The auger motors control is handled by the timing control module and the Dial-A-Fire.
8. TIMING CONTROL MODULE
The timing control module is mounted on the right hand side rear pillar of the stove. The module controls the
switching of power to the auger. The modules switching duty is controlled by the Dial-A-Fire.
9. 200°F (93°C) MANUAL RESET TEMPERATURE SENSOR
This sensor (located on the right side firewall) has a red push button located in its center. This is a safety device.
In the event that the convection blower fails, this sensor will overheat and shut off power to the auger motor.
