Sherwood EF-3 BAYI technical manual 11.160F 71C TEMPERATURE SENSOR, Vacuum Switch, Igniter

11.160°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, cooling the unit.

12.140°F (60°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 140°F (60°C).

-When the auger is turned off via the dial-a-fire, the exhaust temperature will drop, when it goes below 140°F (60°C) the sensor will turn the stove off.

13.120°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 exhaust temperature reaches 120°F (49°C).

14.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.

15.IGNITER

This is a heating element used to ignite the fuel. When the start up switch is activated, the igniter is activated by the start up timer. Air passes through the igniter tube, which becomes super heated drying the fuel and then igniting the fuel through convection.
