Induced Draft Blower (*63)
The induced draft blower is also referred to as a “combustion” blower,
since its purpose is to establish flow of combustion air through the heat
exchanger. Mounted at the outlet of the secondary heat exchanger, the
blower establishes a negative pressure within the heat exchanger and
exhausts the flue products outside the structure.
Blower motors operate at a fixed speed.
