DELTA
DELTA OPTIONS
Just a few comments about your Delta 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.
Temperature control can be accomplished by adding the
thermostat option (part FD-HC4). The thermostat automa-
tically controls the amount of combustion air to the fire,
leaving your home at an even preset temperature. If you
plan to heat your home with the fireplace, the thermostat
option will increase comfort, end the fuss of continual man-
ual adjustment, and reduce wood consumption.
For more heat output and increased air circulation, you can
add the internal blower (part FD-HB5-N). For larger homes
in colder climates, this is an important option if you plan to
use the fireplace as an important 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 room directly above or adjacent
to the room with the fireplace which you
would like to heat, you may consider the
gravity vent option (part FD-VD). The gra-
vity vent distributes hot air to this room and
requires no blower to assist its operation.
However, with the internal blower (part FD-
HB5-N) installed, there will be some
increase in warm air movement to the room
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 incorpo-
rate the central heat option (parts FD-HC6
and FD-HB6). A thermostatically controlled
blower takes heat from the fireplace, and
distributes the warm air throughout your
home - even several stories up or down.
WALL THERMOSTAT (FD-HC4)
This optional kit allows you to control the temperature by a
remote electric wall mounted thermostat.
NOTE: It is strongly recommended that this kit be installed
during framing so that the wiring can be easily hidden.
1. Remove both right side louvers. They are held in place
by springs underneath, so push down from the top and pull
forward.
2. The damper motor and transformer are mounted on a
bracket in the bottom right hand corner of the fireplace (see
Figure 19).
3. BEFORE fastening the controls with the 2 screws pro-
vided, thread the supplied chain through the spare keyhole
in the draft control and attach a pendant to the end, just like
the chain that is beside it. Let the chain down on the same
side of the heat shield as the existing chain, and attach it
to the lever on the damper motor with another pendant.
Push the pendant snug into the hole in the lever. Then
mount the controls to the bracket.
