BLOCKED VENT SWITCH
A Blocked Vent Switch is mandatory for installation with an oil-fired
appliance that normally operates with its vent system under a negative
pressure. This device is intended to detect a blocked vent system,
responds to hot flue gases backing up through its heat transfer tube,
and can be wired to shut off the oil burner. It requires manual resetting.
