Installing the Draft Inducer
WARNING: Turn OFF the main power to the furnace before proceeding with the installation of
the draft inducer.
ATTENTION: It is very important to install the draft inducer on a vertical section of stack to isolate the
inducer from excessive heat and ash buildup. Never install the draft inducer on a horizontal section of stack
close to the furnace breach where heat and ash will damage the inducer motor.
1. Refer to Figure 4Q. Follow the instructions included with the draft inducer to mount the draft
inducer on the section of single-wall vertical stack.
2. Position the draft plate all the way out so that it does not reduce the draft produced by the draft
inducer. You will adjust the draft plate later as part of
Adjusting the Draft Overfire
(Section 8).
