**Using total air volume and system static pressure requirements determine from blower tables rpm and bhp required. Maximum usable hp of motors furnished by Lennox are
shown. If motors of comparable hp are used be sure to keep within the service factor limitations outlined on the motor nameplate.
***For LPG models a field conversion kit is required and must be ordered extra. See Optional Accessories table.
