2) Part FD-HC6-1: A back draft damper
3) Part FD-HB6 : A maximum 636 C.F.M. Blower with a
variable speed motor, 2 noise
reduction collars, a blower speed
control, and a mounting bracket.
NOTE: Both part numbers must be used together for
this system. Use of any substitutes will de-certify the
system.
The 8” back-draft damper prevents hot air from travelling
into the ‘C’ vent (single wall) ducting unless the Central
Heat Blower (FD-HB6) is operating. When the thermos-
tat calls for heat, the blower turns on and opens the
one-way valve. At the same time, the room air is drawn
through the upper and lower louvers, which mixes and
reduces the overall temperature of the forced air that
travels through the ducting.
WARNING: If you are ducting out of the top of the
fireplace and the back-draft damper is not installed, the
central heat ducting may become too hot for the
surrounding combustible materials. Any substitute for
the FD-HC6-1 kit will void all warranty coverage by RSF
ENERGY.
Installation
1. Remove the cover left side only.
2. Cut the insulation to the size of the opening and
remove the cover plate underneath (it is taped in place).
3. Install the back draft damper crimped side up, making
sure it is pushed all the way down. Bend out the 4
middle tabs to fasten the damper to the top of the
fireplace. From the louver opening bend out two of the
lower tabs to prevent the damper from being pulled out.
4. Before proceeding with the installation of the blower,
make sure that the electrical service to the blower is in
the “OFF” position. All wiring should be in accordance
with local ordinances and the National Electric Code.
NOTE: The blower can basically be installed anywhere
in the home, however some thought should go into the
planning to ensure that the blower noise does not affect
rooms you would like kept quiet. If the central heating
system ductwork is passing through an area in your
home that you do not wish to be heated, then the ducting
should be insulated. Length of runs should be as short
as possible to conserve space and minimize cost. Maxi-
mum duct length should not exceed 50 feet from the
fireplace to the furthest outlet. There is a loss of about
15% performance at 50 feet. Note: The blower
automatically shuts off if the air temperature reaches
180° F inside the ducting.
5. Locate the blower in a convenient location. The blower
may be installed vertically or horizontally. The horizon-
tal installation can utilize either the supplied mounting
bracket or, if you want to install the blower farther away
from the ceiling, you can use plumber’s strapping. A
vertical installation must include the mounting bracket.
Note: If you have an existing hot air system, you may
safely ‘tie in’ to this hot air system. However, no hot air
