Electrical Connections - Bradford White 46392H Installation & Operating Manual

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.
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.
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 (latest editions).
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.
This indirect-fired water heater is supplied with an aquastat
temperature control. This aquastat must be properly installed in
the aquastat well location of the water heater. Refer to Figure 6.
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 (49°C) 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.
