Return Air Temperature; Minimum Clearances To Combustible Materials - Bryant LEGACY 912SA Product Data

This furnace is designed for continuous return- -air minimum temperature of 60_F (15_C) db or intermittent operation down to 55_F (13_C)
db such as when used with a night setback thermometer. Return- -air temperature must not exceed 80_F (27_C) db. Failure to follow these
return air limits may affect reliability of heat exchangers, motors and controls.
