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