HEATILATOR ECO CHOICE
12. Red Call Light
The red call light is on the side of the junction box, below the
fuse. The function of the red call light is to indicate that the
thermostat is calling for heat.
13. Reset Button
The reset button is located on the back of the appliance in the
upper right corner below the heat output control switch. The
function of the button is to momentarily open the thermostat
circuit, which restarts the system.
14. Thermocouple
The thermocouple is located on top of the firepot inside
the thermocouple cover (ceramic protection tube). The
thermocouple sends a millivolt signal to the control box
indicating the preset temperatures of the green and red lights
have been obtained.
15. Thermostat
The appliance is designed to run on a 12 volt AC thermostat.
The heat anticipator should be set on the lowest setting
available.
16. Snap Disc #1 (Convection Blower) 110°F
Snap disc #1 is located on the right side of the appliance behind
the right side panel. There are 2 purple wires connected to
it. This snap disc turns the convection blower on and off as
needed. Power is always present at snap disc #1.
17. Snap Disc #2 (Fuel Delivery Interrupt) 175°F
Snap disc #2 is located on the center of the convection plenum
above the convection blower. There is an orange and a black
wire connected to it. This snap disc will turn off the feed system
which will turn off the appliance if an over fire condition should
occur or if the convection blower should fail to operate. If this
occurs you will have to manually reset the snap disc.
18. Snap Disc #3 (Back Burn Protector) 250°F
Snap disc #3 is mounted on the back of the auger tube in the
center of the appliance and has a reset button. There are two
grey wires connected to it. To access it remove the right side
panel. If the fire tries to burn back into the feed system or push
exhaust up the feed tube, this snap disc will shut the entire
system off. This disc must be manually reset.
19. Vacuum Switch
The vacuum switch is located on the lower right side of the
appliance behind right side panel. There are two red wires
attached to it. This switch turns the feed system on when
vacuum is present in the firebox. The vacuum switch is a
safety device to shut off the feed motor if the exhaust or the
heat exchanger system is dirty or plugged or if the firebox
door is open.
