General
E2 series electric furnaces are approved for use in
mobile/modular homes. The E2 series furnaces are
approvedfordownflowandupflowinstallationsasfree
standingunits, or foralcove installations. All furnaces
models are approved for “zero” inch clearance from
combustible materials. For downflow alcove
installations a grille with frame may be attached to the
top of the furnace and all paneling and trim flushed to
it.
This installations provides an access door for future
installationofanairconditioning/heatpumpcoil. AllE2
seriesfurnacesareA/C,heatpumpadaptable.Referto
table 2 For optional air conditioner/ heat pump
equipment. TheE2seriesincludestwomodels: E2EH
and E2EB models. The E2EH models are equipped
with a two speed blower and require the addition of a
replay package for the addition of air conditioning or
heat pump. The E2EB furnaces are equipped with a
multi-speed(4-speed)blower,blower relay,andcabinet
insulation.

Sequence of operation
With the circuit breakers in the on position and the
blower switch in the auto position. One half of the
control heating element and motor electrical circuit is
activated. When the contacts close in the wall
thermostat 24 volts is supplied by the 240/24 volt
transformerto thesequencer heater. Thisheats abi -
metal in the sequencer which closes a set of contacts
and completes the circuit to the no.1 element and the
blowermotor. Astheheatercontinuestobuildupheat,
the bi-metal closes the remaining circuits to other
elements, until all elements are on. The “off” cycle is
reverse of the “on” cycle the blower and no.1 element
are first on and the last to be de-energized.

Sequencer (Figure 2)
In general all sequencers operate the same way. In
some applications one sequencer may be sufficient
(10 and 12 kw models) in other applications. One two
or more sequencers may be required.
Important: Sequencers should never be mixed. If
differentbrandsofsequencerareusedandtheirtiming
may be different.
Testing Sequencer
1. Shut off the power supply to the furnace, there
could be two circuits. Be sure both "A" and "B"
circuits are de-energized.
a. Removeall wiresfrom thesequencer (making
note of wire color and terminal location). The
bi-metalheaterportionofthesequencerwillbe
unmarked and at the bottom, closest to the
mounting plate. The switching portion will be
marked M1 through M8 depending on the
number of switches. Refer to unit wiring
diagram.
b. With an ohmmeter, test for continuity across
thebi-metalheaterterminals. Thereshouldbe
70to90ohmsof resistance.Ifthemeterreads
no continuity, the bi-metal heater is open and
mustbereplaced.TheOHMSvalueshouldbe
70 to 90 across the bi-metal.
Figure 2. Sequencer
c. With an ohmeter check all switches in the
sequencer. They are labled M1-M2, M3-
M4...refertoFigure2.Alloftheswitchesshould
be open and have no continuity.
2. With all power on to furnace, and thermostat
contacts closed: using a voltmeter (set scale for
220 vac.) On contact terminals of sequencer,
check each set of terminals of sequencer, check
each set individually. If you read voltage, contacts
are open. If you do not read voltage, contacts are
closed. Allow a maximum time (110 seconds) for
heater to close contacts. If any of the contacts
remain open after three minutes the sequencer is
defective and should be replaced.

of these symptoms exist replace the transformer.
Heating Elements (Figures 4 & 5)
The heating elements used are of modular design
consisting of helical-coiled nichrome resistance wire.
Aninsulatedwireformedassemblysupportstheheating
elements. All elements are rated at 240 volts. Each
element is individually controlled by a switch of the
sequencing system and is protected by a limit switch.
The function of the heating element, of course, is to
heattheairpassedacrossthembytheblowersystem.
Testing Heating Elements (Ohmmeter)
1. Shut off all electric supply to furnace
2. Remove all wires from terminals of heating coils
3. Using the ohmmeter test from terminal to terminal
of the coil-must show continuity-if not replace
element assembly.
4. Using the ohmmeter test from heating element
terminal to ground wire in the control panel, there
should be no continuity. If there is the coil is
grounded and must be replaced.
Caution: Heating elements must always be replaced
byanidenticalkWreplacement. Substitutionbyhigher
kW’s or elements of a different design may result in
unsafe operation of the furnace. Lower kW rated
elements will reduce output and may result in
unsatisfactory operation of the appliance. Refer to
element rating labels and furnace wiring diagrams.
Refer to unit wiring diagram section for wiring of
sequencer for each model furnace.
Control Transformer (Figure 3)
All E2 furnaces are equipped with a 30 VA, 240/208
vac primary, 24 vac secondary transformer.
The function of the transformer is to supply the 24
volts for the low voltage circuit which activates the
controls. Note: neverreplacea transformerwithone
oflessVArating: howeverahigherratedtransformer
canreplace alower ratedunit. Example: unit has30
VA replacement can be 40 VA.
Checking Transformer
1. Usingavoltmeter,testpowersupplyontheprimary
leads of the transformer- must be 240 v +/- 10%.

leads.
2. Remove wires from the secondary side of the
transformer. Or find the area where the wires
terminate and remove from component.
3. Use the voltmeter check the output of the
transformer, it should read 22 to 28 volts. If not,

Figure 6. Cooling Relay
Cooling Relay (Figure 6)
The E2EB has a factory installed cooling relay. The
cooling relay operates the air circulator at the high
speed when the relay is energized. The relay is
energized by the low voltage circuit by the g terminal
ofthethermostat. Atthesametimeitbreaksthecircuit
to the heating speed of the air circulator. the cooling
relay has one set of normally closed and one set of
normally open contacts.
Testing Cooling Relay
1. Turn off all power supply to furnace.
a. Remove all wires from cooling relay.
b. Using ohmmeter, test from terminal no. 1 to
terminalno.3thecoilshouldhaveresistanceof
around 76 ohms. If there is no continuity, the
relay has a open coil and must be replaced.
c. Using ohmmeter, test from terminal no.5 to
terminal no. 6 there should be continuity, if no
continuity isshownrelayisdefectiveandmust
be replaced.
d. Replace wires on terminal no.1 and 3 restore
power supply.
e. Energizerelaybypositioningthefanswitchon
the thermostat to the fan position. The relay
should click.
f. Using ohmmeter, test terminals 2 and 4 there
should be continuity. If no continuity relay is
defective.
g. Turn off all power to furnace, reconnect all
wires to relay and restore power.
Limit switches
A limit switch is a heat sensing device utilizing a bi-
metal disc to open a set of normally, closed contacts.
The limit device is a safety which can be compared to
a fuse or a breaker in a electrical circuit. The function
of the limit switch is to open the electrical circuit to the
heating elements if over heating should occur. This
could be caused by air circulator failure, dirty filters,
lackofreturnair,restrictedducts,etc. Alllimitswitches
used are of the automatic reset type. On cool down
they will automatically reset.
Testing the Limit Switches
1. Shut off all electric supply to furnace.
2. Allow enough time for limit to cool down ( 5 to 10
minutes)
3. Remove wires from terminals of limit switches.
Note: all limit switches will be located on the
heating element rack face plate with red wires
attached to them.
4. Usingtheohmmeter,testfromterminaltoterminal
continuity must be read. If no continuity is read
aftercooldowntime,switchisdefectiveandshould
be replaced.
Caution: Limit switches must always be replaced by
theiridenticalreplacementpart,i.e.Samesetting,style
limits on the E2 series are either single or double pole
type thermo disc. Under no circumstance should a
limitofahighersettingorofadifferenttypebeinstalled.
Replacement with a lower setting limit may result
cycling of the control and insufficient heat output.
