IMPORTANT
In Canada all electrical wiring is to be done in accordance
with the latest edition of CSA C22.1 Part 1 and/or local
codes. In the U.S. use the National Electrical Code ANSI/
NFPA 70. The heating contractor must also comply with
both the Standard for Controls and Safety Devices for
Automatically Fired Boilers, ANSI, ASME CSD-1.
A power module is supplied with the Vitodens 100-W
boiler, which requires a 120VAC power supply, for
simplified installation the boiler is equipped with a 3-prong
plug for use with a standard 120VAC wall receptacle.
The voltage at connector X3 must be 120V (see wiring
diagram).
