ELECTRICAL CONNECTIONS

Thermostat

Install a 24-volt thermostat (not provided) in a proper location. The location of the thermostat has an

important effect on boiler system operation. BE SURE TO FOLLOW THE INSTRUCTIONS INCLUDED WITH THE THERMOSTAT.

Grounding

Permanently ground the boiler according to local codes and the National 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.

Follow local electrical codes.

 

Electric Power Supply

All electrical work must conform to your familiar with wiring and codes in general,

local codes as well as the National Electrical Code. If you are not have a competent electrician do this job.

On packaged boilers, the boiler controls are all wired at the factory. You need only connect a 115 volt

electrical supply to the L1 and L2 terminals on the aquastat relay and two thermostat wires to the T and T

terminals on the same aquastat relay (see figure below).

Run a separate circuit from a separate overcurrent protection device in your electrical service entrance panel. This should be a 15 ampere circuit. Locate a shut-off switch at the boiler. It must be turned offduring any

maintenance. Solder and tape or securely fasten these connections with wire nuts.

Oil Burner Wiring

For boilers packaged with oil burners, the burners are wired at the factory. For boilers shipped knockdown or packaged without a burner, wiring connections are shown in the electrical wiring diagrams of this manua!.
