3. Place blower against lower rear wall of
rebox outer wrapper with exhaust port di-
rected upward and thermodisc positioned
up near fireplace bottom. Thermodisc
must be oriented near replace bottom
as shown in Figure 29, in order to sense
temperature and properly operate. Blower
will be held in position against back wall
by magnets incorporated onto blower
housing (see Figure 29).
4. Be certain that all wire terminals are
securely attached to terminals on blower
motor and thermal switch and that screw
for thermodisc bracket and green ground
wire is tight.

ing plate provided in lower fireplace
cavity by placing plastic control shaft
forward through round hole (see Figure

7. Check to make sure that power cord is
completely clear of blower wheel and
that there are no other foreign objects in
blower wheel. Also double check all wire
leads and make sure wire routing is not
pinched or in a precarious position. Cor-
rect accordingly.
8. Turn on power to duplex outlet if previ-
ously turned off per warning in column 2,
page 17.
9. Plug in blower power cord to duplex
outlet.
10. Blower will only run when speed control
knob is in the ON position and thermal
switch senses temperature after replace
begins to heat up. Blower speed can be
adjusted by rotating control knob. To turn
off, turn knob fully counterclockwise until
it clicks off. If blower is ON and has been
running with replace operating, blower
will continue to run for a short time after
replace has been turned off. As thermal
switch cools down, blower shuts down
automatically.
11. Peel off the backing paper and stick the
supplied wiring diagram decal on the
rebox bottom approximately 12" in front
of the blower (see Figure 28, page 18).
