2. Connect remaining wire terminal to the “TH”
terminal on the control valve. Make sure that
wire terminals are in the positions on your unit
as pictured in Figure 32, page 20. If wires are
not “crossed” the thermostat will not work.
3. Route the 25 ft. wire to a convenient location
to mount your wall switch (no outside walls).
WARNING: Do not connect
the switch to a power source.
Electrical shock and/or fire haz-
ard will occur.

minals of the provided wall switch.
5. Install the wall switch and cover in the wall.
INSTALLING LOG SET AND
SCREEN
1. Remove log packaging material and discard
packaging. Gently place log on burner sup-
port (see Figure 35). The log should fit flat
against top of burner support and log locator
tabs fit into the slots under the log. Do not
allow log to contact flame. If flame contacts
log, soot will be created.
2. Reattach screen by placing the notches in the
screen frame over the shoulder screws and
pushing down.
