DANGER
Positively assure all electrical connections are unpowered before attempting installation or service of
electrical components or connections of the boiler or building. Lock out all electrical boxes with padlock
once power is turned off.
WARNING
The primary control may be damaged or may not function properly if 120 volt power supply is NOT wired into
control as follows:
The 120V interrupted hot (black) wire must be connected to the primary control black wire, the 120V neutral
(white) wire must be connected to the primary control white wire and the 120V constant hot (red) wire must
be connected to the primary control red wire.
WARNING
Failure to properly wire electrical connections to the boiler may result in serious physical harm.
Electrical power may be from more than one source. Make sure all power is off before attempting any
electrical work.
Each boiler must be protected with a properly sized fused disconnect.
Never jump out or make inoperative any safety or operating controls.
