Section 8 is divided into three parts. Section 8A includes instructions for using the Quick Start
Menu. Section 8B covers basic installation and wiring. Section 8C includes more detailed setup
instructions and wiring diagrams.
8B.1 Installation Warnings
Single pole switches, including those of safety
controls and protective devices, must not be wired in
a grounded line.
All electrical connections are made on the terminal
blocks that are located inside the control panel.
Wiring connections are shown in Figure 34.
All internal electrical components have been
prewired. No attempt should be made to connect
electrical wires to any other location except the
terminal blocks.
WARNING
The appliance must be electrically grounded in
accordance with the requirements of the authority
having jurisdiction or, in the absence of such
requirements, with the latest edition of the National
Electrical Code, ANSI/NFPA 70, in the U.S. and with
the latest edition of CSA C22.1 Canadian Electrical
Code, Part 1, in Canada. Do not rely on the gas or
water piping to ground the metal parts of the boiler.
Plastic pipe or dielectric unions may isolate the boiler
electrically. Service and maintenance personnel, who
work on or around the boiler, may be standing on wet
floors and could be electrocuted by an ungrounded
boiler. Electrocution can result in severe injury or
death.
