be at the top so they lie flat. Bend out the
lower edge of the valve at 4 places inside
the fireplace with pliers so that it can't be
pulled out again. Diagram 2. 6) Connect the inlet of the blower to the outlet
of the valve using 8 inch diameter metal
ducting (rigid or flex). Any other size will
not work properly.
7) Duct-work can then be run to the desired
rooms following good warm air distribution
practices. Up to six 5 in. diameter runs can
be installed from this system.
Note: The cross sectional area of the
distribution system must total at
least 50 square inches. For exam-
ple: If 5 in. pipe is used for distri-
bution, the cross section of each
is 20 square inches. Three runs of
5 in. pipe is minimum. Shut-offs
must not be installed on the reg-
isters feeding the room with the
thermostat. To prevent the duct
and motor from overheating 50
square inches of grill/duct must
remain open during operation.
WARNING: When the central heating blow-
er is in operation it actually removes air
from the room containing the fireplace.
If this room can be closed off from the
rest of the house, (i.e. with a door) a grille
with at least 100 square inch open area
must be installed to allow the air to get
back to the fireplace. Otherwise periodic
smoking of the fireplace will be experi-
enced.
8) When installing the blowers for the central
heating option, a thermodisc must be in-
stalled (supplied with one-way damper).
Install thermodisc on the inside (top right
side) against the back surface using the
two screws, lock washers and nuts sup-
plied. See diagram 3.
9) Wire fan to a 120 volt, 15 amp breaker
through the line voltage thermostat. See
wiring diagrams on page 14. If used, the
5) Locate the blower in a convenient location
near the fireplace. In a 2 story home one
good location would be in the ceiling of the
basement because you must be able to
access it for oiling and replacement.
Note: The blower can be installed al-
most anywhere in the home. How-
ever, some thought should be put
into the planning, to ensure blow-
er noise is kept away from rooms
that want quiet. Length of runs
should be kept to a minimum to
conserve space and minimize
cost. Maximum duct length should
normally not be more than 50 feet
between the fireplace through the
fan to the outlet farthest away.
There is a loss of about 15% per-
formance at 50 feet.
WARNING: The WarmHearth may
be tied into your home's central
warm air duct system by linking
into the HOT air duct in any position
you may choose, however, caution
must be used to ensure that hot air
produced by the WarmHearth can-
not be drawn back into the central
heating furnace.

thermostat should be located in the principal
room heated through the duct system. Do
NOT install it in the room the fireplace is built
in. Near the fireplace a simple shut-off
switch must be installed in series with the
thermostat. If the internal blower (Part #
000-912) is also installed, the shut-off
switch will be mounted just beside the
variable speed control.
Note: Do not install an independent variable
speed control on the central heating
fan, unless the manufacturer of the
central heating fan permits it.
10) Frame around fireplace and ducting as
shown. Use metal ducting only; don't use
plastic in the chase. The diagram shows
some ways of ducting the hot air from the
fan. You are not restricted in the size of
pipe, as long as the total cross sectional
area of all runs combined is not less than 50
square inches. The diagram shows alter-
nate fan locations. Only one external fan is
allowed.
11) Ducting is tested at 1 in. clearance to fram-
ing for the first 6 feet and 1/2 in. thereafter
and no stand-offs are required. All ducting
should be insulated to reduce heat loss. Use
only approved insulation.
