2. Connect wire harness and power cord terminals. Connect the blue jumper wire to the blower motor terminal and the right side terminal of the thermal switch. Connect the black wire to the left side of the thermal switch and the white wire to the other remaining blower motor terminal. Note: The power cord outer insulation sleeve may have to be stripped slightly to allow enough wire length to reach and make all connections. DO NOT trim excessive length away. Just enable enough to make all connections securely. 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 29 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 29). 4. Be certain that all wire terminals are securely attached to terminals on blower motor and thermal switch and that the screw for the thermodisc bracket and green ground wire is tight. 5. Mount the speed control box against the mounting plate provided in the lower fireplace cavity by placing the plastic control shaft forward through the round hole (see Figure 27, 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 27, page 19).

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 previously turned off per the 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 supplied wiring diagram decal on the firebox bottom approximately 12" in front of the blower (see Figure 28, page 20).

Fireplace Installation Continued Installing Gas Piping to Fireplace Location WARNING: A qualified service person must connect fireplace to gas supply. Follow all local codes. CAUTION: For propane/LP units, never connect fireplace directly to the propane/LP supply. This heater requires an external regulator (not supplied). Install the external regulator between the fireplace and propane/LP supply. WARNING: For natural gas, never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas. Installation Items Needed Before installing fireplace, make sure you have the items listed below. • external regulator (supplied by installer) • piping (check local codes) • sealant (resistant to propane/LP gas) • equipment shutoff valve * • test gauge connection * • sediment trap • tee joint • pipe wrench • approved flexible gas line with gas connector (if allowed by local codes) * A CSA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the CSA design-certified equipment shutoff valve from your retailer. For propane/LP connection only, the installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14 inches of water. If you do not reduce incoming gas pressure, fireplace regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 31, page 22. Pointing the vent down protects it from freezing rain or sleet. BlueVariableFan SwitchFan Switch(N.O.) GreenWhiteOn110/115 V.A.C.
