3. Place the blower against the lower rear
wall of the firebox outer wrapper with
the exhaust port directed upward. Attach
Thermal disc magnetic bracket to the bot-
tom of the firebox sub-floor. The thermo
-
disc must be oriented near the fireplace
bottom as shown in Figure 28, in order to
sense temperature and properly operate.
The blower will be held in position against
the back wall by the magnets incorporated
onto the blower housing (see Figure 28).
4. Be certain that all wire terminals are
securely attached to terminals on blower
motor and that the screw retaining the
green ground wire is tight.
5. Mount the speed control box against the
mounting plate provided in the lower fire
-
place cavity by placing the plastic control
shaft forward through the round hole (see
Figure 26, page 20).
6. While supporting speed control, secure
control shaft with lock nut by pushing and
turning lock nut with pliers clockwise until
it is tight against mounting plate. Place
control knob provided on shaft (see Figure
26, page 20).
7. Check to make sure that the power cord is
completely clear of the 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. Correct
accordingly.
8. Turn on power to duplex outlet if previ-
ously turned off per the warning in column
2, page 19.
9. Plug in blower power cord to duplex outlet.
10. The blower will only run when the speed
control knob is in the ON position and
the thermal switch senses temperature
after the fireplace begins to heat up. The
blower speed can be adjusted by rotating
the control knob. To turn off, turn knob fully
counterclockwise until it clicks off. If the
blower is ON and has been running with the
fireplace operating, the blower will continue
to run for a short time after the fireplace has
been turned off. As the thermal switch cools
down, the blower shuts down automatically.
11. Peel off the backing paper and stick the
supplied wiring diagram decal on the
firebox bottom approximately 12" in front
of the blower (see Figure 27, page 20).
