that are shipped unmounted are noted on the bill
of materials. These parts, where feasible, are pack­aged and shipped with the units. Upon receipt of
shipment, all units should be checked carefully for

FACTORY TEST

All L.J. Wing gas-fired unit heaters are given a
complete operational and control circuit check-out
before final shipment. A copy of the test report is
available upon request.

II. INSPECTING YOUR L.J. WING

GAS-FIRED UNIT HEATER

A. Check unit nameplates to be sure that the

model is correct.

B. Examine the furnace nameplate attached to

the air inlet to be sure that the type of gas
the unit is arranged for is the same as the
gas supply.

C. Check motor nameplate for voltage and cur-

rent rating characteristics.

D. Turn the fan manually to assure that it is cen-

tered in the fan ring and does not strike. If
necessary re-align.

Note: If discrepan-

III. INSTALLATION LOCATION

This inspection is extremely important and
should be completed with the greatest care given
to detail. A good pre-start inspection will insure
against possible unit damage on start-up and will
save valuable analysis time in the event a malfunc­tion should occur on start-up.

• Check to see that all factory installed pipe
plugs have been removed.

• Check supply voltage against unit voltage.

Check all electrical connections for tightness

•
at all terminals in the main control panel and
optional remote control panel.

• Check that all fuses are installed.

• Check fan area to insure freedom of rotation.

• Check all areas for cleanliness.

• Secure all access doors.

• If revolving discharge section is ordered, the
gear motor is secured so that it will not
become damaged during transit. Check to
see that gear motor has been loosened and

orks freely against the spring.

IX. SEQUENCE OF OPERATION

IX. (TYPICAL)

A. Room Thermostat Calls for Heat (Winter

Mode):

1. Magnetic fan motor starter coil is ener­gized.

2. Revolving discharge motor is energized
(when furnished).

3. As each power venter proves airflow the
spark ignition module is energized.

B. Room Thermostat Satisfied:

Entire unit is de-energized resulting in shut
down of diaphragm gas valves, fan motor,
and revolving discharge motor (when fur­nished).

C. The Summer-OFF-Winter Switch allows

operation of the fan unit without firing the
duct furnaces (Summer Mode).

X. TROUBLE SHOOTING

A. Refer to attached furnace manual for Trouble

Shooting instructions regarding power venter,
pilot burner, and main burner.

B. If fan motor fails to operate:

1. Check the magnetic starter and reset if
tripped.

2. Check room thermostat.

Check Summer-OFF-Winter switch if

3.
used.

4. Manually energize starter.

5. If the motor is found defective after all
checks are made, repair or replace.

C. If the revolving discharge (if used) fails to

rotate when the fan unit is operating:

1. Check the fuse in the revolving discharge
motor splice box.

2. Check for free movement of the dis­charge rotation, pull the drive wheel away
from discharge collar before rotating.

3. While drive wheel is away from dis­charge, check for shaft slippage.

4. Observe if the revolving discharge motor
drive wheel rotates.

5. Test for 110 voltage in the junction box
on revolving discharge motor. If motor still
fails to operate, replace the motor.
