High Limit Snap Discs F-170: 3/4 diameter air stream
High Limit Snap Discs F-170 - 3/4" diameter air stream mount with manual reset for pellet stoves.
These switches are used to shut down the stove (stop the Auger) when the stove overheats. Certain stoves require the F170, which means the stove will shut down at 170 degrees.
We also carry the F-200. See link below.
