FIREPLACE INSTALLATION
Continued
The installation of a wall switch allows you to activate the gas
control valve and turn the replace on and off. The wall switch is
to be connected to the incoming 120 volt regular household wir-
ing that supplies the electricity to the replace. Refer to wiring
diagram below.
Note: If using optional wireless hand-held remote control, the wall
switch must be in the ON position to be operational. The remote
control then becomes the switching mechanism for replace op-
eration.
1. Open lower louver panel of rebox.
2. The WRC model receiver does not require a battery. The
receiver can be installed by rst plugging the short extension
cord into the replace receptacle. Then plug the receiver unit
into the extension cord. Finally plug the ignition module plug
into the receiver unit (see Figure 46).
3. Activate the remote handset battery by removing the insulating
tab on the back of the handset (see Figure 47). The battery is
included pre-installed.
4. Once the battery is activated the unit is ready to use.
5. Close lower louver panel.
