must be electrically bonded to
ground in accordance with the
requirements of the authority having
jurisdiction or, in the absence of
such requirements, with the
National Electrical Code, ANSI/NFPA
70, and/or the Canadian Electrical
Code Part I, CSA C22.1, Electrical

CAUTION
•
No changes may be made to the wiring
of the boiler.
•
All connections should be designed in
accordance with the applicable
regulations.
•
Label all wires prior to disconnection
when servicing controls. Wiring errors
can cause improper and dangerous
operation.
•
Verify proper operation after servicing.
When connecting the power supply, follow
these guidelines:
•
Connect 120 VAC power wiring to the line
voltage power terminals.
•
The boiler requires 120 VAC, 60 Hz power
from a properly grounded circuit.
•
A 15 amp (recommended) fused disconnect
or service switch must be installed as
required by the code.
•
Do not rely on the gas or water piping to
ground the boiler. Ground locations are
provided inside the boiler.
•
The wiring diagram is located on the inside
of the boiler front cover.
A manually-operated remote switch should
be located outside the boiler room door for
shutting down the boiler. Consideration
should be given to protect the switch
against tampering. If there is more than one
door to the boiler room, a switch should be
located at each door.
