Millivolt Wall Switch Installation
To install your millivolt wall switch, an approved wall
box should be installed in a location suitable to you.
The thermostat wire should be routed from the wall box
to the gas control valve, and should be pulled up to the
valve's wiring terminal as shown in Figure 17.
The two wires, letter “A”, should not be removed or
changed. Remove switch wires, Letter B. The two
female ends of your wire can be connected to the two
outer connections just below the screw terminals as
shown in Figure 17.
Now the wall switch can be wired as shown in Figure
18. The wires can be connected to either poles as
they carry only millivolt current. No ground is used at
the wall switch. See the lighting instructions for the
millivolt wall switch on Page 16. Wall switch must be
for millivolt operation.
Do not connect 120 Volts to wall switch.

Optional Wireless Remote Installation
Two remote control kits are offered. The standard ON/
OFF model is a WRD-I and the thermostat model is a
WRST-K
The remote receiver will be similar to that shown in
Figure 19.
There will be a battery terminal and two wire leads.
The remote receiver does not need to be secured to
the fireplace, but can be placed behind the lower
louver panel and placed on the bottom of the unit next
to the gas control. (Fig. 19)
The enclosed jumper wires can be attached to the
receiver wires by joining the female connectors from
the receiver. All connections should be made as shown
in the remote kit instructions. The wires from your
receiver can be connected to the two outer terminals
on the valve, making sure it is the two outer terminals
and not the center one (Fig. 22) You may now refer to
the lighting instructions for use. The log set should not
be modified to accept any other type of remote control
as no guarantee may be make regarding proper
function. Refer to remote manufacturer’s instructions
for battery replacement.
