7. To install the blower (for the FDHB6 only): attach the
noise reduction collars to either side of the blower
using 1/2" self-tapping screws.
8. Ductwork can then be run to the desired rooms. Up to
six 5" or five 6" diameter runs can be installed from
this system.
NOTE: Runs must be balanced as air travels along the
path of least resistance. Balance the airflow by diameter
and length of runs. Longer runs should have larger diam-

eters. Houses vary in size and layout, so duct systems
must be specifically designed for each home. The dia-
grams on this sheet are examples only. The cross sec-
tional area of the distribution system must total at least
50 square inches. If you have more than 50 square inch-
es, some of the system may be shut off, but there must
always be 50 square inches of ducting open at all times.
For example, if 5" pipe is used for distribution, the cross
section of each is 20 square inches. The minimum allow-
able ducting would be three runs of 5" pipe.
(Figures 27 & 28) illustrate two examples of "tying-in" to
existing ductwork. Directing air in the right direction will
reduce reverse flow when the existing furnace blower is
off. Some reverse flow will not cause any problems.
CAUTION: Tie-ins into existing ductwork must be
down stream from the existing furnace.
NOTE: When the central heating blower is in operation,
it removes air from the room containing the fireplace. If
this room can be closed off from the rest of the house
(e.g. with a door), a grill with at least a 100 square inch
open area must be installed to allow the air to return to
the fireplace. Otherwise periodic smoking from the fire-
place will result.
9. Wire the blower to a 115-volt, 15-amp breaker
through the thermostat provided. The variable speed
switch provided should be installed in a convenient
location near the fireplace so the blower can be shut
off during refueling. The blower control center should
be placed in an accessible location near the blower. It
should be mounted in a 4 x 4 electrician's box. You
have two options of how you can connect the central
heat blower to the blower control assembly.
