Overview
A fixed-setting (non-adjustable, one-way) vacuum pressure switch for ComfortBilt pellet stoves.
The switch watches the draft through its sensing hose and only lets the stove run when the exhaust blower is pulling properly. It works the same as the adjustable style; choose whichever you prefer.
