Figure 35 - Wall Switch Wiring Diagram
WARNING: Do not wire remote
wall switch to main power supply
(Standard 120v household current).
WALL SWITCH INSTALLATION
Since the fireplaces use a valve that operates
on millivolt current generated by the pilot, a
wall switch (not included) may be used to
activate the gas control valve without the
use of normal household electricity. A hand-
held, ON/OFF remote control is standard
with this unit. Wall switch is optional. If the
wall switch is installed, the hand-held, ON/
OFF remote cannot be used.
1. To remove the louvers, simultaneously
pull both top end spring latches towards
the center of the appliance until they
are disengaged from locating holes.
Repeat for bottom end spring latches
and pull outward. Reverse the proce-
dure to install louvers back onto the
appliance (see Figure 34).
2. Connect the 18 ga. wires from wall
switch (not included) to the gas con-
trol valve and microswitch, as shown
in Figure 35.
