For Installation In Masonry Fireplace Only
Distribution blowers
The blowers are already mounted to the insert for installer
convenience. Each blower is secured to the insert body with
three screws, as shown.
First, make a determination of which side you'll want the
power cord coming from. On the determined side, install the
short ground wire with ring terminal to the ash lip below and
behind the blower, using the green screw and tooth washer
from the hardware kit.
Notice the high temperature insulated wire pair that runs
across the back of the air chamber beneath the insert,
and attaches to each blower. This is what links the two
blowers together. On the side that you want the power cord,
remove the knockout from the surround panel and insert
the power cord connectors through it. Pull the insulated wire
connections from the blower motor and in their place, hook
up the two female connectors from the cord. Next, attach
the two male connectors from the cord to the insulated
wire ends that were removed from the blower. Plug the
green wire from the power cord into the short green wire
that you installed. Secure the excess cord wires behind the
surround using the wire ties and install the cord clamp into
the knockout hole in the surround.
