ABSTRACT:
Apparatus is disclosed for operating a gas furnace system (100) having an air intake (102) for supplying external air into a sealed chamber (110) for input to a gas burner assembly (118). Exhaust air from within the combustion burning chamber (140) is applied through an exhaust duct (170) directly into an environment (174) which is external to the furnace system (100) but which is still within the environment to be heated. The furnace system (100) also includes a conventional fan limit assembly (142) wherein the typical high limit setting is substantially decreased so that a blower fan (160) is activated at lower than normal temperatures. In addition, the conventional gas furnace burner is replaced with a burner assembly (118) having substantially small burner ports (130).
