EL296UHE SERIES UNITS
EL296UHE series units are high efficiency condensing gas
furnaces used for upflow or horizontal applications only,
manufactured with Lennox Duraloktheat exchangers
formed of aluminized steel. EL296UHE units are available
in heating capacities of 44,000 to 132,000 Btuh and cooling
applications up to 5 tons. Refer to Product Specifications
Manual for proper sizing.
Units are factory equipped for use with natural gas. Kits are
available for conversion to LPG operation. EL296UHE
model units are equipped with the SureLight®two-stage
integrated control. EL296UHE unit meets the California Ni
trogen Oxides (NOx) Standards and California Seasonal
Efficiency requirements. All units use a redundant gas
valve to assure safety shut-off as required by C.S.A.
All specifications in this manual are subject to change. Pro

I-UNIT COMPONENTS
EL296UHE unit components are shown in figure 1. The
gas valve, combustion air inducer and burners can be ac
cessed by removing the access panel. Electrical compo
nents are in the control box (figure 2) found in the blower
section.
EL296UHE units are factory equipped with a bottom return
air panel in place. The panel is designed to be field re
moved as required for bottom air return. Markings are pro
vided for side return air and may be cut out in the field.
CAUTION
Electrostatic discharge can affect elec
tronic components. Take precautions
to neutralize electrostatic charge by
touching your hand and tools to metal
prior to handling the control.
A- Control Box
1. Control Transformer (T1)
A transformer located in the control box provides power to
the low voltage section of the unit. Transformers on all
models are rated 40VA with a 120V primary and a 24V sec
ondary.
2. Door Interlock Switch (S51)
A door interlock switch is wired in series with line voltage.
When the inner blower access panel is removed the unit
will shut down.

Circuit Breaker
3. Circuit Breaker (CB8)
A 24V circuit breaker is also located in the control box. The
switch provides overcurrent protection to the transformer
(T1). The breaker is rated 3A at 32V. If the current exceeds
this limit the breaker will trip and all unit operation will shut
down. The breaker can be manually reset by pressing the
button on the face. See figure 3.

WARNING
Shock hazard.
Disconnect power before servicing. Integrated
control is not field repairable. If control is inoper
able, simply replace entire control.
Can cause injury or death. Unsafe operation will re
sult if repair is attempted.
4. Integrated Control (A92)
Units are equipped with the SureLight®two-stage, inte
grated control. The system consists of a ignition / blower
control (figures 4 and 5) with control pin designations in
tables 1 and 2 and ignitor (figure 14). The control and ignitor
work in combination to ensure furnace ignition and ignitor
durability. The control provides gas ignition, safety checks
and indoor blower control with two-stage gas heating. The
furnace combustion air inducer, gas valve and indoor blow
er are controlled in response to various system inputs such
as thermostat signal, pressure and limit switch signal and
flame signal. The control features a seven-segment LED
display, indicating furnace status and error codes. The
LED flashes in single digits. For example using table 4 un
der LIMIT CODE, an “E” followed by “2” followed by “5” fol
lowed by “0”, the limit switch circuit is open. The control also
has two unpowered (dry) 1/4” contacts for a humidifier and
a 120 volt accessory terminal. Both rated at (1) one amp
each.
Electronic Ignition
At the beginning of the heat cycle the integrated control
monitors the first stage and second stage combustion air
inducer pressure switch. The control will not begin the
heating cycle if the first stage pressure switch is closed (by-
passed). Likewise the integrated control will not begin the
second stage heating cycle if the second stage pressure
switch is closed, and will remain in first stage heat. Howev
er, if the second stage pressure switch closes during the
first stage heat pre-purge, the control will allow second
stage heat. Once the first stage pressure switch is deter
mined to be open, the combustion air inducer is energized
on low (first stage) heat speed. When the differential in the
pressure switch is great enough, the pressure switch
closes and a 15-second pre-purge begins.

Page 8
After the 15-second pre-purge period, the SureLight®igni
tor warms up for 20 seconds after which the gas valve
opens for a 4-second trial for ignition. The ignitor remains
energized during the trial until flame is sensed. If ignition is
not proved during the 4-second period, the control will try
four more times with an inter purge and warm-up time be
tween trials of 35 seconds. After a total of five trials for igni
tion (including the initial trial), the control goes into Watch
guard-Flame Failure mode. After a 60-minute reset period,
the control will begin the ignition sequence again.
NOTE - During abnormal conditions such as low supply
voltage or low outdoor temperatures and the low fire pres
sure switch does not close, the combustion air inducer will
switch to high speed. After the low & high pressure switch
close, the unit will proceed with a 15 sec pre-purge, fol
lowed by a 20 sec ignitor warm up, then ignition on high-
fire. After 10 to 20 seconds of high fire operation the unit will
switch to low fire.
Two Stage Operation / Thermostat Selection DIP
Switch
The control can be utilized in two modes: SINGLE-STAGE
thermostat or TWO-STAGE thermostat. The thermostat
selection is made using a DIP switch and must be posi
tioned for the particular application. DIP switch 1, labeled
T”STAT HEAT STAGE is factory-set in the OFF position for
use with a two-stage thermostat. Move the DIP switch to
ON for use with a single stage thermostat.
While in the single-stage thermostat mode, the burners will
always fire on first-stage heat. The combustion air inducer
will operate on low speed and indoor blower will operate on
low heat speed. The unit will switch to second stage heat
after a “recognition period”. DIP switch 2, labeled SECOND
STAGE DELAY, is factory set in the OFF position for a 7
minute recognition period. The switch can be moved to the
ON position for a 12 minute recognition period, after which
time the unit will switch to second-stage heat. While in the
two-stage thermostat mode, the burners will fire on first-
stage heat. The combustion air inducer will operate on low
speed and indoor blower will operate on low heat speed.
The unit will switch to second-stage heat on call from the
indoor thermostat. If there is a simultaneous call for first
and second stage heat, the unit will fire on first stage heat
and switch to second stage heat after 30 seconds of opera
tion. See Sequence of Operation flow charts in the back of
this manual for more detail.
