MOUNTING AND WIRING
!WARNING
Do not use on circuits exceeding specified volt- age. 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 appli- ance or reversing the neutral and hot wire con- nection to the line can cause shock hazard.
Shut off main gas to heating system until instal- lation 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 experi- ence a minimum of vibration and remain below the maxi- mum ambient temperature rating of 175°F. The control is approved for minimum ambient temperatures of
Any orientation is acceptable.
Refer to the wiring diagram and wiring table when con- necting 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.
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 rec- ommended terminals to mate with those on the control.
The 50A55 has only one serviceable
