Installation, adjustment and service of boiler controls including timing of various operating functions must be performed by a qualified installer, service agency or the gas supplier. Failure to do so may result in control damage, boiler malfunction, property damage, personal injury, or death.

Turn off the power to the boiler before installation, adjustment or service of the Central Point Wiring board or any boiler controls. Failure to do so may result in board damage, boiler malfunction, property damage, personal injury, or death.

This appliance has provisions to be connected to more than one (1) supply source. To reduce the risk of electric shock, disconnect all such connections before servicing.

Risk of electric shock. More than one (1) disconnect switch may be required to de-energize the equipment before servicing.

CENTRAL POINT WIRING (CPW)

Central Point Wiring is an advanced control integration technique that provides complete boiler diagnostic capability and greatly simplifies troubleshooting. At the heart of CPW is the Operations Status Center, which is comprised of two different circuit boards: the CPW board and one or more U-2 Diagnostic Boards.

THE CPW BOARD

The Central Point Wiring (CPW) board serves as the central tie point for connecting all other control components in the boiler. The CPW board provides boiler operating status and fault indication using eight LEDs which function as described in Table L-1
