Maintenance
Replacing the Vacuum Switches
Follow the steps below to replace the vacuum switches. See
Figure 36
for a wiring diagram. When disconnecting each wire, we
recommend marking the wire to ensure they are reconnected in the
correct locations.
Step 1:
Disconnect power and gas supply to the fireplace.
Step 2:
Remove glass barriers. See
Section 10
for installation and
removal of glass. Note: if removing glass from one side only, take
precautions against dirt and damage to the remaining sides.
Step 3:
Remove the access panel and inner valve cover. See
Accessing the Valve
.
Replacing the .40 switch:
Step 4:
The vacuum switches are mounted above the valve. Begin
by removing the silicone tubes connected to the bottom of the switch.
The clear tube connects to the black nipple and the red tube connects
to the grey nipple.
Figure 111.
Step 5:
Disconnect the wires connected to the switch. The blue wire
connects to the closest terminal and the red wire connects to the
farthest terminal when viewed from the front of the fireplace. Do not
connect a wire to the center terminal.
