4. Pass the blower through the bottom louver opening so that the outlet is on the bottom and facing
towards the back (see Figure 3).
5. For all other fireplaces except all Delta fireplaces, push the blower to the back of the fireplace and
turn the outlet so it faces up (see Figure 4).
6. Align the blower between the two centering brackets on the fireplace base.
7. For all other fireplaces except all Delta fireplaces, replace the floor shield.
On an Opel2 or Opel3 fireplace: just replace the floor shield.
On a Focus 320, Onyx2, Opel2C or Opel3C fireplace: the floor shield is made of two parts. The
front section is insulated; the back section is not. Both parts are screwed together and factory
installed to cover the entire floor below the firebox. Once the internal blower is installed, the floor
shield must be modified. Remove the screw and overlap the front section with the back section. If
you ever remove the blower make sure to extend the shield again.
8. Reinstall the magnetic bracket for the bottom louver, if necessary.
9. Replace the ash pan support, the ash pan and the ash pan plug, if necessary.
WIRING FOR ALL FIREPLACES
For complete wiring guidance, refer to the wiring diagram in Figure 5
1. Connect the blue wires from the thermal switch to terminals 4 and 5 in the terminal block as
indicated by the wire markers.
2. Connect the blue wires from the blower to terminals 3 and 6 on the terminal block as indicated by
the wire markers.
3. Install the variable speed switch in a regular 2" x 4" electrical box in a convenient location outside
the fireplace.
4. Using conventional 14/2 wires; connect the variable speed switch to terminals 3 and 4 of the
terminal block.
5. It is possible to install a regular "on/off" switch to bypass the thermal switch to activate the internal
blower manually. The switch needs to be connected with 14/2 gauge wiring to terminals 4 and 5 of
the terminal block. It takes about 30 to 40 minutes for the fireplace to generate enough heat to
activate the thermal switch so it can turn on the blower. With the bypass switch, the blower can be
turned on at any time. Make sure to return the bypass switch to the off position so that the thermal
switch can turn off the blower when the fireplace cools off.
6. Connect terminals 5 and 6 of the terminal block to an 110V circuit with 14/2 wiring. Do not forget to
attach the ground wire to the fireplace ground screw which is next to the terminal block.
7. Arrange all wires in such a fashion that they will not come in contact with the firebox.
