be at the top so they lie fl at.  Bend out the 
lower edge of the valve at 4 places inside 
the fi replace with  pliers so that it can't be 
pulled out again (refer to Diagram 2).
6)  Connect the inlet of the blower to the outlet 
of the valve using 8 inch diameter metal 
ducting (rigid or fl ex).  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 distri-
bution system must total at least 50 
square inches. For example:  If 5 in. 
pipe is used for distribution, 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 
registers 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 blower 
is in operation it actually removes air from 
the room containing the fi replace.  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 fi replace.  
Otherwise periodic smoking of the fi replace 
will be experienced.
8)  When installing the blowers for the cen-
tral heating option, a thermodisc must be 
installed (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 supplied 
(refer to diagram 3).
9)  Wire fan to a 120 volt, 15 amp breaker 
through the line voltage thermostat (refer to  
wiring diagrams in the Installing the Blower 
5)  Locate the blower in a convenient location 
near the fi replace.  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 almost 
anywhere in the home.  However, 
some thought should be put into 
the planning, to ensure blower 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 fi replace through the 
fan to the outlet farthest away.  There 
is a loss of about 15% performance 
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.

Systems section). If used, the thermostat 
should be located in the principal room 
heated through the duct system.  Do not 
install it in the room the fi replace is built in.  
Near the fi replace a simple shut-off switch 
must be installed in series with the thermo-
stat. 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 fi replace 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 
alternate fan locations. Only one external 
fan is allowed.
11) Ducting is tested at 1 in. clearance to fram-
ing for the fi rst 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.
