A. Electric Power Supply
Prior to making any line Voltage connections, service switch at
boiler should be in the off position and the power turned off at
the fuse box.
Run a separate 120 Volt circuit from a separate over current
protection device in the electrical service entrance panel. This
should be a 15 ampere circuit. A service switch has been pre-
wired and located on the exterior boiler jacket. See Figure

box and power supply connection points. Connect black
(hot) lead from the power supply to either of the unused
brass screws on the service switch. Connect the white
(neutral) lead from the power supply to the white screw on
the service switch. Connect the green (ground) lead from
the power supply to the ground (green) screw on the ser-
vice switch. The receptacle on the service switch is always
powered regardless of whether the switch is on or off, and
could be used as a power supply for an external condensate
pump if one is used.
The boiler, when installed, must be electrically grounded in
accordance with the requirements of the authority hav-
ing jurisdiction or, in the absence of such requirements,
with the National Electrical Code, ANSI/NFPA-70, latest
revision. In Canada, electrical wiring shall comply with the
Canadian Electrical Codes, CSA-C22.1 and .2.
Run a 14 gauge or heavier copper wire from the boiler to
a grounded connection in the service panel or a properly
driven and electrically grounded ground rod.
