800SA/801SA: Installation, Start–Up, Operating and Service and Maintenance Instructions

Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

31

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. 5

), you must revise your orientation to

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 

Fig.

 for

furnace wiring information.

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

 and the troubleshooting guide which can

be obtained from your distributor. 
See 

Fig. 51

 for a brief Troubleshooting Guide. 

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.

CARE AND MAINTENANCE

For  continuing high performance and  to minimize  possible  equipment

failure,  periodic  maintenance  must  be  performed  on  this  equipment.

Consult your local dealer about proper frequency of maintenance and the

availability of a maintenance contract.

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.     Verify  proper  operation  after

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.

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.

WARNING

!

FIRE OR EXPLOSION HAZARD

Failure  to  follow  this  warning  could  result  in  personal  injury,  death

1.Spray or aerosol cans, rags, brooms, dust mops, vacuum cleaners, or

other cleaning tools.

2.Soap powders, bleaches, waxes or other cleaning compounds, plastic

or  plastic  containers,  gasoline,  kerosene,  cigarette  lighter  fluid,  dry

cleaning fluids, or other volatile fluids.

3.Paint  thinners  and  other  painting  compounds,  paper  bags,  or  other
