    Ask a Question
    • changing flow switch in my Lopi Pioneer pellet stove. The original switch has two grey wire connectors that I removed from original when taking it out of the stove. The new switch is an after market switch with one labeled C1 and the other labeled 2 NO on the backside. Which grey wire goes to C1 and which one goes to 2 NO or does it matter.

      Since the switch is not polarized it will not matter the order of connection to the vacuum switch.
