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 FDHC4). 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
manual adjustment, and reduce wood consumption.
For more heat output and increased air circulation, you
can add the internal blower (part FDHB5-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 mount-
ing the blower control.
If you have room directly above or adja-
cent to the room with the fireplace which
you would like to heat, you may consider
the gravity vent option (part FDVD). The
gra-vity vent distributes hot air to this
room and requires no blower to assist its
operation. However, with the internal
blower (part FDHB5-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 incor-
porate the central heat option (parts
FDHC6 and FDHB6). A thermostatically
controlled blower takes heat from the fire-
place, and distributes the warm air
throughout your home - even several sto-
ries up or down.
WALL THERMOSTAT (FDHC4)
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 fire-
place (see Figure 19).
3. BEFORE fastening the controls with the 2 screws
provided, 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 pen-
dant snug into the hole in the lever. Then mount the
controls to the bracket.
4. Adjust the chain on the draft control lever until it is just
snug but the damper is still closed. When the damper
motor is energized, the damper should open all the
way. Lock the chain onto the keyhole with another
pendant just like the chain beside it.
5. Wire the thermostat as shown in (Figure 19), using
20/2 wire, making sure the wall control is sufficiently
away from the direct radiation of the fireplace. Make
certain that it is at least 10 ft. away from the fireplace,
