The Enviro M55 exhaust channel with sensor (part 50-2145) fits the Enviro M55 pellet stove and carries the exhaust temperature sensor that shuts the stove down when the fire goes out and exhaust temperature drops below 120°F, flagging the control with a #3 flash code so the stove does not keep running unattended.

When to replace it

If the stove shows a #3 flash code, Enviro's troubleshooting calls for bypassing the sensor at the exhaust blower; if the stove then runs normally, the unit needs cleaning or a new sensor rather than a cleaning alone.
