THERMOSTAT LOCATION AND LOW VOLTAGE CONNECTIONS

THERMOSTAT LOCATION
Install the room thermostat in accordance with the instruction sheet accompanying the thermostat. Run the thermostat lead
wires inside the control compartment. Connect the thermostat as shown on the wiring diagram. Never install a thermostat
on an outside wall or where it will be influenced by drafts, concealed hot or cold water pipes, ducts, lighting fixtures, radiation
from a fireplace, rays of the sun, lamps, televisions, radios or air streams from warm air registers.
LOW VOLTAGE ELECTRICAL CONNECTIONS
To facilitate the thermostat connections to the appliance, low voltage wiring extends through the furnace cabinet and is
wrapped with a label titled "Thermostat Wiring". Connect the field supplied low voltage wiring to the appliance wiring using
solderless connectors. Color coding should be adhered to in order to facilitate future troubleshooting.
