Vogelzang Pellet Stove Vacuum/Pressure Switch. The vacuum switch is an important safety device that ensures a certain pressure is maintained inside the stove. This switch is mounted on the rear of the unit and will be connected to a plastic or silicon hose. If the switch is damaged or not functioning properly it may cause the feed motor to stop turning, an error code to display or not allow the unit to feed fuel during start up.
*Attach vacuum hose to white negative(-) port.*
