A. General. Install wiring and electrically ground boiler
in accordance with authority having jurisdiction or, in
the absence of such requirements, follow the National
Electrical Code, NFPA 70, and/or CSA C22.1 Electrical
Code.
B. A separate electrical circuit must be run from
the main electrical service with an over-current
device/disconnect in the circuit. A service switch is
recommended and may be required by some local
jurisdictions. Install the service switch in the line
voltage “Hot” leg of the power supply. Locate the
service switch such that the boiler can be shut-off
without exposing personnel to danger in the event of
an emergency. Connect the main power supply and
ground to the three (3) boiler wires (black, white and
green) located in the junction box at the inside top of
the boiler jacket. If a low water cutoff is to be used,
connect the low water cutoff so that all 120V power
to boiler is interrupted if the low water cutoff’s switch
opens.
C. Refer to Figures 28 and 29 for details on the internal
boiler wiring.
