LENNOX 80W97 Corporation INDUCER ASSY

Induced Draft Assembly

The Lennox 80W97 Induced Draft Assembly, measuring 4 3/8 in Diameter x 12 1/2 in Length, is a device which reduces air velocity at the unit/appliance interface by using the induced draft principle and allows the home heating system to operate at maximum efficiency in reducing outside air infiltration. The Lennox Induced Draft Assembly has a Thermal Limiting Device installed so that it will allow only one full induction to occur every 7 minutes with a return period of 14 seconds, during periods of no heating demand.

Lennox Induced Draft Assemblies are replacement parts for a variety of gas furnace applications. These parts should be used only as replacements or repair components when the original part is not available.

The induced draft assembly 80W97 is designed for use in Lennox induction furnace models 7FA1-60 and 7FA1-81.

The induced draft (supply) blower assembly is designed to vertically move combustion air and smoke into the furnace. It consists of two parts: an inducer motor driven by a squirrel-cage induction motor and an induced draft blower housing. The inducer motor has a 1/3 horsepower rating. The inducer motor must run at all times, even during a call for heat when other electric furnaces are off or unplugged.

The Inducer Assembly is used on 80P-Series, 90P-Series, 100P-Series and 110P-Series Condensing Units

The draft inducer provides the mechanism to transfer flue gas from the flue collar to the heat exchanger through the induced draft fan. Collection of the induced draft system is accomplished through a multi piece design. Copper, stainless steel and stainless steel alloys are used in the fabrication of this assembly.

The Inducer Assembly is designed for use with Lennox HW Series Condensing Units.
