3.4.10 Electrical Connections
Electrical connections to the boiler are made to the boiler on block X4 in the large electrical junction
box located on the rear of the boiler
(Fig. 3.6).
See the connection diagram in
section 6.4.3.
L1 and L2
are the two “hot” legs and the third leg is the ground wire
(Fig. 3.7).
The boiler requires a dedicated
240V 60 hertz 15 amp circuit. Check local codes for wire type and size. Shielded cable is usually re-
quired. All wires should be fastened to the junction box using the proper connectors. The boiler’s cir-
culator pump (120 Volt) is connected to Terminals 9, 10 and 11 on Block X4 using the same guide-
lines above.
