800SA/801SA: Installation, Start–Up, Operating and Service and Maintenance Instructions
WARNING
!
ELECTRICAL SHOCK, FIRE OR EXPLOSION HAZARD
Failure to follow this warning could result in personal injury or death.
Before installing, modifying, or servicing system, main electrical
disconnect switch must be in the OFF position and install a lockout tag.
There may be more than one disconnect switch. Lock out and tag
switch with a suitable warning label.
servicing.
CAUTION
!
ELECTRICAL OPERATION HAZARD
Failure to follow this caution may result in improper furnace operation
or failure of furnace.
Label all wires prior to disconnection when servicing controls. Wiring
errors can cause improper and dangerous operation.

GENERAL

These instructions are written as if the furnace is installed in an upflow
application. An upflow furnace application is where the blower is
located below the combustion and controls section of the furnace, and
conditioned air is discharged upward. Since this furnace can be installed
in any of the 4 positions (see Fig.
component location accordingly.

ELECTRICAL CONTROLS AND WIRING

The electrical ground and polarity for 115-v wiring must be properly
maintained. Refer to Fig. 24 for field wiring information and to
furnace wiring information.
WARNING
!
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury or death.
There may be more than one electrical supply to the furnace. Check
accessories and cooling unit for additional electrical supplies that must
be shut off during furnace servicing. Lock out and tag switch with a
suitable warning label.
NOTE: If the polarity is not correct, the STATUS LED on the control
will flash rapidly and prevent the furnace from heating. The control
system also requires an earth ground for proper operation of the control
and flame-sensing electrode.
The 24-v circuit contains an automotive-type, 3-amp. fuse located on the
control (see Fig. 28). Any shorts of the 24-v wiring during installation,
service, or maintenance will cause this fuse to blow. If fuse replacement
is required, use ONLY a 3-amp. fuse. The control LED will display
status code 24 when fuse needs to be replaced.
Proper instrumentation is required to service electrical controls. The
control in this furnace is equipped with a Status Code LED
(Light-Emitting Diode) to aid in installation, servicing, and
troubleshooting. Status codes can be viewed at the sight glass in blower
access door. The furnace control LED is either ON continuously, rapid
flashing, or a code composed of 2 digits. The first digit is the number of
short flashes, the second digit is the number of long flashes.
For an explanation of status codes, refer to service label located on
blower access door, or Fig. 44

For Controls With an Amber LED
The stored status code will not be erased from the control memory, if
115- or 24-v power is interrupted.
1. To retrieve status code, proceed with the following:
NOTE: NO thermostat signal may be present at control, and all
blower-OFF delays must be completed.
a. Leave 115-v power to furnace turned on.
b. Remove outer access door.
c. Look into blower access door sight glass for current LED status.
d. BRIEFLY remove insulated terminal wire from the draft
safeguard (DSS) switch until LED goes out, then reconnect it.
NOTE: If wire to LS or DSS is disconnected longer than 4 sec, main
blower starts, and status code is overwritten with a limit circuit 33 code.
2. When above items have been completed, the LED flashes status
code 4 times. Record this status code for further troubleshooting.
3. Check LED status. If no previous faults in history, control will flash
status code 11.
