E F G H FEATURES EL296UHE / Page 4 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® manufactured vent pipe and terminations as an alternative to PVC vent pipe. Must be ordered separately. Tested and listed to the ULC S636 standard in Canada. The PolyPro venting system must follow the uninsulated and unconditioned space vent lengths listed in the table on . 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. Certain Termination Kits are certified to ULC S636 standard for use in Canada only. See Optional Accessories table and dimension drawings.

CONTROLS SureLight® Integrated Furnace Control Contains all necessary controls and relays to operate furnace. Combustion air inducer is operated by the integrated furnace control. Prior to ignition, a pre-purge cycle for 15 seconds is initiated. After the main burners are turned off, a post-purge cycle for 5 seconds is run. Safety Controls - Flame sensor utilizes flame rectification for 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 ignition controls after one hour of continuous thermostat demand after unit lockout, eliminating nuisance calls for service. Thermostat Control - For optimal performance, the use of a high-quality, digital two-stage thermostat with adjustable settings for first stage/second stage, on/off differentials and adjustable stage timers is recommended. Furnace Input Staging Options Thermostat Type Input Staging Available Two-Stage (Conventional)Determined by thermostat demand Single-Stage (Conventional) 2nd-stage heat ON delay (DIP switch setting) OFF - 7 minutes (factory) ON - 12 minutes I EL296UHE / Page 5 FEATURES CONTROLS (continued) Display LED - Seven segment LED displays alpha- numeric information related to diagnostics as well as system operation and status. Diagnostic codes are held in non-volatile memory, immune from power interruptions. Holds up to ten diagnostic codes in order of occurrence for recall on demand. Port on blower door allows for easy viewing. DIP Switch Settings Select Thermostat used - Single-Stage or Two-Stage. Two selectable second stage recognition times (7 and 12 minutes) are available on the control when the furnace is used with a single-stage thermostat. When used with a two-stage thermostat, furnace will only initiate second stage operation with a second stage thermostat demand. Second Stage Delay - Used with single-stage thermostat only. See Furnace Input Staging Options table for details. Blower On/Off Time (Heating) - Blower on time is fixed at 30 seconds, blower off time is adjustable from 60, 90, 120 and 180 seconds (factory setting - 90 seconds). Blower On/Off Time (Cooling) - For air-conditioning applications, blower on time is 2 seconds following thermostat demand for cooling. Blower off time in cooling mode is adjustable from 2 or 45 seconds (factory setting - 45 sec). For air-conditioning applications, blower is automatically energized on thermostat demand for cooling. Heating Speeds - Low Heat or High Heat. Cooling Speeds - Low Cool or High Cool. Continuous Speed - Low Heat (factory setting) - adjustable. Dehumidification - A jumper on the control must be clipped to enable dehumidification. A humidity controlling thermostat or device is also required. During a call for cooling, air volume is automatically reduced, forcing humidity removal by the air conditioner or heat pump system (single stage units or two-stage units running at 2nd stage). After the humidity has reached the desired set-point the cooling air volume returns to its designed rate. Dual-Fuel Operation - A jumper on the control must be clipped to enable operation with a single or two-stage heat pump. The indoor blower is started without delay when a call for heat is received.
