Installation Instructions
Wiring
1. Before installing the blower, wire the receptacle into an
electrical circuit. This should be done before framing the
fireplace. Wire with minimum 60° C wire in accordance with
prevailing codes.
. Remove the external junction box cover by removing the
screw from the left side of the outside firebox wall. Junction
box was installed at the factory.
3. The junction box cover has a factory in-
stalled "romex" style strain relief connector.
After connecting the wires, route the wire
leads through this connector. Refer to the
wiring diagram in Figure 53.
Before Installing the Blower
1. Always turn off the gas supply and allow
the unit to cool down before proceeding.
. Clean the inside of the firebox (wall and
floor), where the blower and wires will be
installed. Make sure the firebox wall and
floor are clean and dry before mounting the
blower.

Installing the Blower

1. Remove the lower access panel by pulling
up and away from unit.
. Remove glass frame by releasing the two
() latches (500 and 600 models have
three (3) latches) below the firebox open-
ing and lifting glass frame up and away
from unit.
3. Use the supplied Velcro on the blower and the magnetic strips to secure the blower to
the firebox wall and floor. Figure 54
4. Remove the tape from the back of the Velcro strips, slide the blower through lower ac-
cess door and position on the inside back firebox wall. The blower should be centered
with the rear blower discharge vent facing up (pointing up between the inside firebox
wall and inner combustion wall). The blower should be
flat against the firebox back wall. Figure 55
5. For 300 models, the air shield can be removed. Figure

6. Align the connector pin on the AC box to the control box
and gently push them together using the guiding block as
a guide. Figure 56
