Wall Thermostat - RSF Woodburning Fireplaces ONYX AP Owner's Manual

ONYX AP OPTIONS
Just a few comments about your Onyx AP options. The size and shape of your home and how you intend to use
your fireplace will determine the options you require.
For a basic, high-efficiency fireplace, you won't need any options or electricity.
Automatic temperature control can be accomplished by adding the thermostat option (part FDHC4). The thermo-
stat automatically controls the amount of combustion air to the fire, leaving your home at an even preset
temperature. If you seriously plan to heat your home with the fireplace, the thermostat option will increase com-
fort, end the fuss of continued manual adjustment, and reduce wood consumption.
For more heat output and increased air circulation, you can add the internal blower (part FDHB5). For larger homes
in colder climates, this is an important option if you plan to use the fireplace as a serious source of heat.
NOTE: It will be difficult to install the internal blower if wiring is not run during framing. If there is any chance that
this option will be installed in the future, power should be run to the fireplace and wire must be run to a switch box
at a convenient place on the wall for mounting the blower control.
If you have rooms directly above or adjacent to the room with the fireplace that you would like to heat, you may
consider the gravity vent option (part FDVO). The gravity vent distributes hot air to these rooms and requires no
blower to assist its operation. However, with the internal blower (FDHB5-N) installed, there will be some increase
in warm air movement to rooms serviced by the gravity vent.
If you desire even heat throughout your home strictly from your fireplace, or if you want to move heat to a remote
area of your home, it is recommended that you incorporate the central heat option (parts FDHB6, FDHC6 and
FDHC6-1). A thermostatically controlled blower takes heat from the fireplace, and distributes the warm air
throughout your home - even a couple of stories up or down.
WALL THERMOSTAT (FDHC4)
This optional kit allows you to control the tem-
perature by a remote electric wall mounted ther-
mostat.
NOTE: It is strongly recommended that this kit
be installed during framing so that wiring can
easily be hidden.
1. Remove both top and bottom louvers. The
top louver is held in place by springs under-
neath, so push down from the top, then
rotate and pull forward. The bottom louvers
can be opened by pulling the right hand side
of the louvers. To completely remove the lou-
vers, when opened, push up the louver to
remove the bottom of the hinge rod from its
hole and pull the louvers.
2. The damper motor and transformer are
mounted on a bracket in the bottom right
hand corner of the fireplace. Mounting
screws are supplied and are already in place
in the bracket (See Figure 16).
3. BEFORE fastening the controls with the 2
screws provided, thread the chain supplied
through the spare keyhole in the draft control
and attach a pendant to the end just like the Figure 16: Thermostat control installation
