power supply at service panel before making
electrical connections. Failure to do so could
result in death or serious injury.
Electric Power Supply
Run a separate 115 volt circuit from a separate over
current protective device in the electrical service entrance
panel. This should be a 15 ampere circuit. Locate a shut-
off switch at the boiler. It must be turned off during any
maintenance. Connect 115 volt power supply to aquastat
terminals L1 (HOT) and L2.
The boiler, when installed, 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 Code. 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.

Install Your Thermostat
The thermostat location has an important effect on the
operation of your boiler system. BE SURE TO FOLLOW
THE INSTRUCTIONS INCLUDED WITH YOUR THERMOSTAT.
Locate the thermostat about five feet (5') above the floor
on an inside wall. It may be mounted directly on the wall
or on a vertically mounted outlet box. It should be sensing
average room temperature.
