Eighteen gauge thermostat wire is highly recommended,
Smaller gauge thermostat wire may be used only if the guideline below
is followed.
Thermostat Wire Length Thermostat Wire Gauge
(Furnace to Thermostat)
0 - 45 feet 22
0 - 70 feet 20
Do not use the thermostat wire smaller than 22 gauge. If thermostat
wire small than 18 gauge is used, pay particular attention that the con-
nections between the different wire sizes are tight.
Operational problems may be caused by loose connections or by the
use of thermostat wire that is too small to carry the required load. Any
such problems are the responsibility of the installer.
A separate 115 V.A.C. supply circuit must be used for the furnace. The
circuit should be protected by a 15 amp fuse or circuit breaker.
Avoid locations where the thermostat could be subject to drafts from
outside, or exposed to direct light from lamps, sun, fireplaces, etc., or
affected by air from a duct register blowing directly on the thermostat.
The wall thermostat should be located 52 to 66 inches above the floor.
The preferred location is on an inside wall situated in an area with good
air circulation, and where the temperature will be reasonably represen-
tative of other living areas the thermostat is controlling.
