  • Page 8: Venting System Length Calculations

    Venting System Length Calculations The Total Equivalent Vent Length (TEVL) for EACH combustion air or vent pipe equals the length of the venting system, plus the equivalent length of elbows used in the venting system from Table 2. Standard vent terminations or factory accessory concentric vent terminations count for zero deduction. See vent system manufacturer’s data for equivalent lengths of flexible vent pipe or other termination systems.

    RETURN AIR TEMPERATURE 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.
