FIREPLACE INSTALLATION Installing Optional Blower Accessory (Cont.) Installing Gas Piping to Fireplace Location
FIREPLACE INSTALLATION
Continued
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 26, page 17).
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 17).
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 previously turned off per the warning in column 2, page 16.
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 counterclock- wise 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 17).
Blower Wiring Diagram
CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.
INSTALLING GAS PIPING TO FIREPLACE LOCATION
WARNING: A qualified service person must con- nect 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.
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
For propane/LPconnection 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 19. Pointing the vent down protects it from freezing rain or sleet.
