Enviro EF-IV I User Manual

12. 160°F (71°C) TEMPERATURE SENSOR
When this sensor (located on the left side firewall) reaches 160°F (71°C), the convection blower will go to high,
bypassing the fan controller and removing excess heat from the unit.
13. 120°F (49°C) N/O TEMPERATURE SENSOR (SHUT-DOWN SENSOR)
This sensor (mounted on the exhaust blower housing) has two functions:
- Should the fire go out, this sensor will shut the stove off when the exhaust temperature drops below
120°F (49°C).
- When the auger is turned off via the dial-a-fire, the exhaust temperature will drop, when it goes
below 120°F (49°C) the sensor will turn the stove off.
14. 120°F (49°C) N/C TEMPERATURE SENSOR (IGNITOR SHUT DOWN SENSOR)
This sensor (mounted on the exhaust channel) will turn the ignitor off when the firebox temperature reaches
120°F (49°C).
15. VACUUM SWITCH
This safety device (mounted on the left side back pillar) detects vacuum in the exhaust system. If the exhaust
blower fails or the vent pipe becomes plugged, this switch will sense that there is no airflow and will stop the
auger from continuing to feed pellets.
16. IGNITER
This is a heating element used to ignite the fuel. When the pellet stove is started, the igniter is energized. Air
passes through the igniter tube over the igniter. The air becomes super heated, drying the fuel and then igniting
the pellets through convection. The igniter is located in the lower center of the firebox next to the inlet air tube.
