7.Install the base onto the wall with the pro- vided screws.
8.Move the temperature adjustment back and forth to insure the bimetal is free from restrictions.

WARNING: Read and follow installation instructions. Instal- lation should be done by a quali- fied installer familiar with low- voltage wiring procedures.
WARNING: Do not connect this switch to any electrical source! Electrical shock and/or fire hazard will occur.
1.Connect one terminal of 25 ft. wire to bottom contact of switch (see Figure 32, page 20).
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.
IMPORTANT: The wire may be shortened but must not be lengthened.
4.Connect one bare wire end to each of the ter- 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.
