Fig. 5 — Remote Control Wiring
for Thermostat Combinations
When thermostat wiring is complete, mount
thermostat to subbase per instructions included
with the control. Do not turn on unit power at this
time; refer to Start-Up section of this publication.
Thermostat heat anticipator setting is 0.6 amps.
REMOVE SHIPPING TAPE on condenser fan, if
not previously removed.
CHECK COMPRESSOR HOLD-DOWN BOLTS -
Compressor is internally spring-mounted. Do not
loosen or remove hold-down bolts.
SET HEAT ANTICIPATOR on thermostat at 0.6
amps.
OPEN GAS SUPPLY LINE VALVE and purge line
by loosening ground joint union (Fig. 4). Tighten
union when gas odor is detected.
ADJUST BLOWER SPEED, if required, to main­
tain heat temperature rise limits given in Table 1.
CHECK MAIN BURNERS
1. Measure and adjust main burner gas input as
described in Service section.
2. Turn main gas valve to ON position and operate
unit for at least 15 minutes with all access
panels in place.
3. With unit operating, remove heating section
access panel. Check burner flames. Flames
should be clear, almost transparent blue. If
flames appear yellow, a change to factory set
primary air adjustment has occurred. Refer to
Fig. 7 and readjust primary air as follows:
Loosen primary air spoiler locking screw.
Rotate
adjustment tab counterclockwise
(slightly) until flame becomes blue. If flames
lift off burner ports, turn adjustment tab
clockwise. Retighten locking screw.
FINAL HEATING SYSTEM CHECKOUT - Move
thermostat dial above and below room temperature
setting several times, pausing at least 5 minutes
between cycles. Check pilot flame, main burner
ignition, flame characteristics and indoor (evap­
orator) fan motor time delay relay operation.
Replace heating section access panel.
COOLING SYSTEM CHECKOUT
1. Turn power on.
