Main Power; Changing Single Circuit To Two Circuits; Field Wiring - Bradford White Brute Deluxe BMT2H Installation And Operation Instructions Manual

(
Brute Deluxe
500-2000), Install & Operating
The appliance must be electrically grounded in
accordance with the requirements of the authority having
jurisdiction or, in the absence of such requirements, with
the latest edition of the National Electrical Code, ANSI/
NFPA 70, in the U.S. and with latest edition of CSA
C22.1 Canadian Electrical Code, Part 1, in Canada. Do
not rely on the gas or water piping to ground the metal
parts of the boiler. Plastic pipe or dielectric unions may
isolate the boiler electrically. Service and maintenance
personnel, who work on or around the boiler, may be
standing on wet floors and could be electrocuted by an
ungrounded boiler.
Single pole switches, including those of safety
controls and protective devices must not be wired in a
grounded line.
All electrical connections are made in the field
wiring terminal strip, which is located at the right side of
the appliance.
NOTE: All internal electrical components have been pre-
wired. No attempt should be made to connect electrical
wires to any other location except the wiring box.

5.1 Main Power

All Brute Deluxe non-pump-mounted heaters
require a single 120-volt fused supply. See
over current protection ratings.
Pump-mounted Brute Deluxe models 500 to
1500 use a single 120-volt fused supply. The installer
can change these units to use a separate circuit for the
pump, if desired. Instructions to make this change are
found in Section 5.1.1.
Pump-mounted Brute Deluxe models 1750 and
2000 require two 120-volt fused supplies. See
for over current protection ratings.

to the main distribution terminal block. These
wires will be black/white, white and green
respectively.
