Internal Blower for Delta, Onyx, Opel
The internal blower kit will increase the circulation of heated air generated by the fireplace into the room
where it is installed. If you desire to distribute the heat in different rooms, please refer to central heating
and zone heating kits (FO-FDHB6-1, FO-FDHC6, FO-FDHCZ1 and FO-FDHCZ2).
All wiring should be in accordance with local ordinances and the National Electric Code.
One thermal switch is all that is required to operate the internal blower, the central heating blower or
both. If the thermal switch is already installed, skip to the installation of the internal blower.
INSTALLATION ON A DELTA
Installation of the thermal switch assembly
1. Remove the bottom central and right louvers.
2. The thermal switch goes in the middle of the central bottom louver opening, on the flange at the
back of the shield below the firebox, with the thermal switch facing upwards (see Figure 1). Make
sure to push the “S” clips onto the flange as far as they will go.
Installation of the internal blower assembly
3. Pass the blower through the bottom louver opening so that the outlet is on the bottom and facing
towards the back (see Figure 1).
4. Slide the blower between the two centering brackets on the fireplace base.
INSTALLATION ON AN ONYX OR OPEL
Installation of the thermal switch assembly
1. Open the bottom louver.
2. Under the firebox, on the left of the right firebox leg, you will find a welded bracket (see Figure 2).
Install the thermal switch on that bracket, with the thermal switch facing upwards. Make sure to
push the “S” clips onto the flange as far as they will go.
If you have an ash pan in your fireplace, make sure that it is still possible to remove the ash pan
once the thermal switch is installed.
Installation of the internal blower assembly
3. Remove the vibration rubber dampers at both ends of the blower and reinstall them on both ends of
the central support (see Figure 3).
4. If your fireplace is equipped with an ash pan: remove the ash pan plug, remove the ash pan and
then remove the ash pan support by unscrewing the screw located at the back of the support.
