ABSTRACT:
A temperature-dependent flow regulator for a combustion exhaust flue comprises a vent pipe connected to the flue by a first end, the opposite end having a movable valve member disposed therein, and thermostatic expansion means sensing the temperature of the flue, the expansion means being directly connected to the valve member via a linkage. The expansion means directly drives the valve member, independently of suction created by draft in the flue.
