SECTION VI
ELECTRICAL CONNECTIONS
Install electric wiring in accordance with National Electric Code or
the Canadian Electrical Code and local regulations. See the boiler’s
installation manual for wiring diagrams.
This indirect-fired water heater is supplied with an aquastat
temperature control. This aquastat must be installed in the aquastat
well location of the water heater. Refer to Figure 5. Remove the
cover and loosen the clamping screws. Insert the aquastat capillary
bulb to the well bottom as shown and screw the aquastat clamp
securely in the well groove. The aquastat acts as a thermostat for
zone control and should be wired accordingly. Refer to the boiler or
zone control manufacturer’s instructions if any additional wiring is
required. The control is factory set at 120°F and care should be made
to not rotate this dial while wiring the control. Once electrical
connections are complete, secure the aquastat cover back in place.
AT NO TIME SHOULD WATER HEATER OPERATION
TAKE PLACE WITHOUT THE COVER ON THE CONTROL.
DANGER
Positively assure all electrical connections are unpowered before
attempting installation or service of electrical components or connections
of the water heater or building. Lock out all electrical boxes with padlock
once power is turned off.
WARNING
When installed, the water heater must be electrically grounded in
accordance with local codes or, in the absence of local codes, with the
National Electrical Code, ANSI/NFPA 70, and /or the CSA C22.1
Electric Code.
Failure to properly wire electrical connections to the water heater may
result in serious physical harm.
Electrical power may be from more than one source. Make sure all
power is off before attempting any electrical work.
