266180-BIM-B-0209 closely regulate average room air, preferably, where there is air move- ment back to furnace. Care should be used to locate thermostat away from hot air discharge openings, lights, etc. Locating height of thermo- stat is important. Thermostat should be located 52” to 66” (132 - 167.6 For personal safety be sure to turn the electrical power OFF at the cm) above the floor. -
