FEATURES DIRECT VENT / NON-DIRECT VENT SEALED COMBUSTION SYSTEM Furnace features a sealed combustion system and can be installed in either Direct Vent or Non-Direct applications. In Direct Vent applications, combustion air is supplied from outdoors and flue gases are discharged outdoors. In Non-Direct Vent applications, combustion air is supplied from indoors and flue gases are discharged outdoors. NOTE - Lennox has approved the use of DuraVent PolyPro and Centrotherm InnoFlue manufactured vent pipe and terminations as an alternative to PVC vent pipe. Must be ordered separately. Tested and listed to the ULC S66 standard in Canada. The polypropylene venting system must follow the uninsulated and unconditioned space vent lengths listed in the table on Page. Refer to the Installation Instructions for additional details. Optional Accessories Termination Kits Facilitates installation of combustion air intake pipe and flue exhaust pipe. Refer to venting table in this bulletin to determine pipe size needed and proper termination kit required. See Optional Accessories table and dimension drawings. Termination Kit - Concentric - Direct Vent Applications or inch kit contains concentric termination assembly, reducer bushing and 45 elbow. inch kit for -045-070 models contains an outdoor exhaust accelerator. Kit requires single hole penetration of roof or wall for installation. Roof Termination Flashing Kit is available for use with inch Kits. CSA certified.

Also available for use with inch (use inch flashing) Concentric Vent Termination Kits used in vertical venting rooftop applications. CONTROLS Integrated Furnace Control Contains all necessary controls and relays to operate furnace. Combustion air inducer is controlled by the integrated furnace control. Prior to ignition, a pre-purge cycle for 5 seconds is initiated. After the main burners are turned off, a post-purge cycle for 5 seconds is run. Integrated furnace control continuously monitors line voltage and maintains the igniter power at a constant level to provide consistent lighting and maximum igniter life. Flame sensor assures safe and reliable operation. Should loss of flame occur, the integrated furnace control will initiate 4 re-attempts at ignition before locking out unit operation for 60 minutes. Watchguard type circuit automatically resets integrated control after one hour of continuous thermostat demand after unit lockout, eliminating nuisance calls for service. Fan control consists of adjustable blower timed-off delay (60, 90, 0, 80 seconds - factory setting 0 seconds) and fixed blower timed-on delay (0 seconds heating, seconds cooling). For air-conditioning applications, blower is automatically energized on thermostat demand for cooling. Integrated furnace control has one red LED to indicate status and indicate diagnostic codes. Push button recall of the last 5 diagnostic codes aids in troubleshooting. Integrated furnace control has built-in twinning capability ( TWIN terminal on control) to operate two furnaces simultaneously without any additional controls. A field supplied isolation relay is required to operate the twinned (no thermostat connection) furnace.
