Thermostat Installation

1. If an old thermostat is being replaced, is in a satisfactory
location and the wiring appears to be in good condition, use
existing wiring. If in doubt, use new wire.
2. If a new thermostat location is chosen, or if this is a new
installation, thermostat cable must first be run to the location
selected. All wiring must agree with local codes and
ordinances. These instructions discuss pulling the thermostat
wire from the attic, but it may be run from a basement or crawl
space using similar methods.
3. Before drilling hole in wall at selected location, drive a small
finishing nail through the ceiling in the corner of the wall and
ceiling above the thermostat location. Pull the nail out and
push a small stiff wire through the hole so it can be found in
the attic. Drill a ½-inch hole through the ceiling wall plate.
4. Probe for obstructions in the partition. Then drill ½-inch hole
through wall at selected location for thermostat.
5. From the attic, feed the thermostat wire or a stiff wire through
wall until even with thermostat location.
6. Snag thermostat wire through hole and pull wire through hole
in the wall so that 6 inches of wire protrudes.
7. Route wire to wall heater.
Mounting the Thermostat
1. To remove thermostat cover, grasp cover and pull straight
outward. Carefully remove and discard the packing tab
protecting the switch and contacts.
2. Connect thermostat wires to the terminal screws on the back
of thermostat base.
3. Push any excess wire back through hole in wall and plug hole
with insulation to prevent drafts from affecting thermostat
operation.
4. Be sure to level thermostat for best appearance, fasten
thermostat base to wall through mounting holes with screws
provided.
5. Replace the thermostat cover.
