FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE.
DESCRIPTION
The 50A55-474 and 50A55-571 are automatic gas interrupted ignition controls that employ a microprocessor to continually monitor, analyze, and control the proper operation of the gas burner, inducer, and fan.
Signals interpreted during continual surveillance of the thermostat and flame sensing element initiate automatic ignition of the burner, sensing of the flame, and system shut-off during normal operation.
These controls incorporate system fault analysis for quick gas flow shut-off, coupled with automatic ignition retry upon sensing a fault correction.
PRECAUTIONS
! GENERAL PRECAUTION |
Application of this type of control may cause flame rollout on initial start-up and could cause personal injury and/or property damage.
Replace only with exact model number, including dash number. Failure to use exact replacement control could cause personal injury and/or property damage.
If in doubt about whether your wiring is millivolt, line, or low voltage, have it inspected by a qualified heating and air conditioning contractor or licensed electrician.
Do not exceed the specification ratings.
All wiring must conform to local and national electrical codes and ordinances.
This control is a precision instrument, and should be handled carefully. Rough handling or distorting components could cause the control to malfunction.

! CAUTION
To prevent electrical shock and/or equipment damage, disconnect electric power to system at main fuse or circuit breaker box until installation is complete.
Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.
This control is not intended for use in locations where it may come in contact with water. Suitable protection must be provided to shield the control from exposure to water (dripping, spraying, rain, etc.).
!WARNING
Do not use on circuits exceeding specified voltage. Higher voltage will damage control and could cause shock or fire hazard.
Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring will damage thermostat and could cause personal injury and/or property damage.

*These times will vary depending on option switch position. The control is factory-set at 0 sec. delay to cool off and 100 sec. delay to heat off. See OPERATION section for further information.
†This time will vary depending on the condition of the jumper. With the jumper installed, the delay-to- cool-off is set at 0 seconds. To obtain an 80second delay-to-cool-off, clip the jumper wire and separate the jumper legs.
MOUNTING AND WIRING
!WARNING
Do not use on circuits exceeding specified voltage. Higher voltage will damage control and could cause shock or fire hazard.
! CAUTION
To prevent electrical shock and/or equipment damage, disconnect electric power to system at main fuse or circuit breaker box until installation is complete. Failure to earth ground the appliance or reversing the neutral and hot wire connection to the line can cause shock hazard.
Shut off main gas to heating system until installation is complete.
Route and secure all wiring as far from flame as practical to prevent fire and/or equipment damage.
INSTALLATION
NOTE
All wiring should be installed according to local and national electrical codes and ordinances.
The control must be secured to an area that will experience a minimum of vibration and remain below the maximum ambient temperature rating of 175°F. The control is approved for minimum ambient temperatures of -40°F.
Any orientation is acceptable.
Refer to the wiring diagram and wiring table when connecting the 50A55 control to other components of the system.
UL approved, 105°C rated 18 gauge, stranded, 2⁄64” thick insulation wire is recommended for all low voltage safety circuit connections. Refer to 50A55 specification sheet for recommended terminals to mate with those on the control.
White Rodgers 50a50-112 Manual
UL approved 105°C rated 16 gauge min., stranded, 4⁄64” thick insulation wire is recommended for all line voltage connections. Refer to 50A55 specification sheet for recommended terminals to mate with those on the control.
The 50A55 has only one serviceable part–an automotive type fuse, which protects the low voltage transformer from damage if its output is short-circuited. If the fuse has opened up, remove whatever caused the short circuit and replace the fuse with only a 3 Amp automotive type fuse. If the fuse is not the cause of the control’s problem, replace the entire 50A55 control. There are no other user serviceable parts.
