ABSTRACT:
A combination powered flue products exhaust and preheated combustion air supply assembly is provided for use in association with a heating furnace so that flue exhaust products are given a positive exhaust to the outside while a balanced pre-heated combustion air supply is simultaneously and positively pulled inside. A compartmented main housing is provided having flue products exhaust and combustion air compartments. A flue products exhaust fan is provided in the flue products exhaust compartment and a simultaneously activated and driven combustion air intake fan is provided in the combustion air compartment. An outside air intake pipe is connected to the main housing so as to deliver combustion air to the combustion air compartment for delivery to the furnace area upon selective activation of the combustion air intake fan. A flue products exhaust pipe concentrically positioned within the air intake pipe is provided in association with the flue products exhaust compartment so as to deliver hot flue exhaust products to the outside atmosphere upon selective activation of the flue products exhaust fan. An automatic air pressure controlled air intake damper is provided in the air intake pipe so as to close the air intake pipe when the fans are not running. An automatic air pressure controlled flue products exhaust damper is provided in the flue products exhaust pipe so as to close the flue products exhaust pipe when the fans are not running.
