H73.1
7.1 LOw vOLTAGE wIrING - THErmOSTAT
h53.1
The thermostat and control wiring should be a minimum of 18 awG copper. excessive lengths of wire may
result in enough voltage drop to impair the proper functioning of the furnace. for thermostat wires in excess of
25 feet (7.6m), use 16 awG; 50 feet (15.2m), use 14 awG.
7.2 THErmOSTAT LOCATION
h53.2
The thermostat should be located approximately 5 feet (1524mm) above the fl oor, on an inside wall where there
is good natural air circulation, and where the thermostat will be exposed to average room temperatures. avoid
locations where the thermostat will be exposed to cold drafts, heat from nearby lamps or appliances, exposure to
sunlight, heat from inside wall stacks, etc.
