WARNING: Turn OFF the main power to the boiler 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 breach where heat and ash will damage the inducer motor.
