recommended and may be required by some local
jurisdictions. The circuit should be run to the junction
box mounted on the front of the boiler back plate in the
control compartment (See Figure 1), and connected to
the proper leads therein. Wires from the low voltage
thermostat should be run to terminals R and G on
the transformer. Install wiring and ground boiler in
