3.Place the blower against the lower rear wall of the firebox outer wrapper with the exhaust port directed upward and the thermodisc positioned up near the fireplace bottom. The thermodisc must be oriented near the fireplace bottom as shown in Figure 30, page 20, 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 30, page 20).

4.Be certain that all wire terminals are securely at- tached to terminals on blower motor and thermal switch and that the screw for the thermodisc bracket and green ground wire is tight.

5.Mount speed control box by placing plastic control shaft through opening in switch bracket (see Figure 28, page 19).

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 28, page 19).

7.Check to make sure that power cord is com- pletely 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. Correct accordingly.

8.Turn on power to duplex outlet if previously turned off per warning in column 1, 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 sup- plied wiring diagram decal on the firebox bot- tom approximately 12" in front of the blower (see Figure 29, page 20).
