THERMOSTAT
Install a 24volt 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 con-
nection in the service panel or a properly driven and
electrically grounded ground rod.
WarNiNg
Turn off electric power at fuse box before making
any line voltage connections. Follow local electri-
cal codes.

ELECTRIC POWER SUPPLY
All electrical work must conform to your local codes
as well as the National Electrical Code. If you are not
familiar with wiring and codes in general, have a com-
petent 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 Ll and L2 terminals on the aquastat relay
and two thermostat wires to the T and T terminals on
the same aquastat relay (see gure below).
Run a separate circuit from a separate over-current
protection device in your electrical service entrance
panel. This should be a 15 ampere circuit. Locate a
shutoff switch at the boiler. It must be turned off during
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
manual.
