Thermostat Installation

1. Thermostat 78355 or any millivolt thermostat.
2. If an old thermostat is being replaced and is in a
satisfactory location and the wiring appears to be
in good condition, use existing wiring. If in doubt, use
new wire.
3. If a new 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 cover
bringing the wire down from the attic but it can be
run from a basement or crawl space using similar methods.
4. Before drilling a hole in the 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.
5. Probe for obstructions in the partition. Then drill a
½-inch hole through wall at the selected location for
thermostat.
6. From the attic, feed the thermostat cable or a stiff wire

through wall until even with thermostat location.
7. Snag thermostat cable through the hole and pull the
cable through the hole in wall so that 6-inches of
cable protrudes.
8. Route cable to wall furnace.
MOUNTING THE THERMOSTAT
1. To remove thermostat cover, squeeze both sides
and lift. Carefully remove and discard the packing tab
protecting the switch contacts. See Fig 17.
2. Connect the thermostat wires to the terminal screws
on the thermostat base. Make sure the wiring
does not interfere with thermostat operation.
3. Push any excess wire back through the hole in the
wall and plug the hole with insulation to prevent
drafts from affecting thermostat operation.
4. Being sure to level the thermostat for best
appearance, fasten the thermostat base to the wall
through the mounting holes with the screws provided.
5. Replace the thermostat cover.
