Optional Wall Switch or Thermostat Installation
Do not connect 110-120 VAC to the gas control valve or wiring system of this fireplace. The switch and
wiring must be installed by a qualified installer.
This fireplace includes an optional wall switch (with wire) to
operate the fireplace burner without accessing the internal
on/off switch. A thermostat may be used instead.
Route the wire from inside the fireplace, through the grommet
on either side of the fireplace (see illustration to the right) to
the switch. The wall switch (or thermostat) may bypass the
fireplace on/off switch or be installed in parallel or series
configuration (see below).
Caution
:
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation.
Warning
: Make sure all wiring is secure and does not
contact hot or moving components.
