Electrical Connections (Advanced Gas Package)
The solenoid valve within the Advanced Gas Package requires an electrical connection
between the gas box and product control box to allow the temperature controller relay
to activate the electrical valve. When the valve is activated the gas can flow. Depending
on the option specified when ordering the furnace, the temperature controller relay is
configured to be triggered either by a program segment output or a temperature
alarm.
A cable is provided with a solenoid connector socket at one end, and a relay connector
at the other.
