Part 4 - Heater Control and Wiring

A. Control
A surface mount thermostatic control has been provided for
accurate temperature adjustment.
B. Wiring
Wiring is to be done in accordance with all applicable local
and state codes. Turn off all power related to the boiler before
starting any wiring procedures. It is recommended that a
disconnect switch be installed between the boiler control and
the water heater.
When wiring the water heater and controls be sure to label
all wires to ease future maintenance. Wiring errors can cause
improper and dangerous operation.
A thermostat connection has been provided on the top of the
water heater for easy wiring and accurate control. See Figure
7. Connect the wires from the thermostat to the terminals
marked + (Positive) or - (Negative).
