BEFORE
fastening the controls with the 2 screws pro-
vided, thread the supplied chain through the spare key-
hole 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 pendant 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 15), 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, but in the same room.
CIRCULATING BLOWER (FDHB5-N)
NOTE: It is important that the wiring for the blower kit is
installed during framing so that the wiring can be easily
hidden.
1. Remove the bottom louver. (See operation #1 in the
above section.) Pull the louver from the right hand side
toward you. Lift the louver to remove the bottom of the
hinge rod from its hole. Remove the top of the hinge rod
from the top hole.
2. The damper motor and transformer are mounted on a
bracket in the bottom right hand corner of the fireplace
(see Figure 15).
