Section 1 -
GENERAL INFORMATION
WARNING
Brute units must be installed in accordance with the
procedures detailed in this manual, or the Bradford
White warranty will be voided. The installation must
conform to the requirements of the local jurisdiction
having authority, and, in the United States, to the latest
edition of the National Fuel Gas Code,ANSI Z223.1/
NFPA54. In Canada, the installation must conform
to the latest edition of CSAB149.1 Natural Gas and
Propane Gas Installation Code, and/or local codes.
Where required by the authority having jurisdiction,
the installation of Brute boilers must conform to
the Standard for Controls and Safety Devices for
Automatically Fired Boilers,ANSI/ASME CSD-1. Any
modications to the boiler, its gas controls, or wiring
may void the warranty. If eld conditions require
modications, consult the factory representative before
initiating such modications.
1.1 Introduction
This manual provides information necessary for the
installation, operation, and maintenance of Bradford White
Brute appliances. Read it carefully before starting the
installation.
All application and installation procedures should be reviewed
completely before proceeding with the installation. Consult
the Bradford White factory, or local factory representative,
with any problems or questions regarding this equipment.
Experience has shown that most operating problems are
caused by improper installation.
Brute is protected against over pressurization. A pressure
relief valve is included with each Brute. Some Brutes may
require that the PRV be installed prior to lling the system.
DANGER
The inlet gas pressure to the appliance must not
exceed 13” W.C. (3.2kPa).
All installations must be made in accordance with
1) American National Standard Z223.1/NFPA54-Latest
Edition “National Fuel Gas Code” or
2) CSA B149.1 “Natural Gas and Propane Installation Code”
or in Canada reference the B149.1 latest edition and with
the requirement of the local utility or other authorities having
jurisdiction. Such applicable requirements take precedence over
the general instructions contained herein. All electrical wiring
is to be done in accordance with the local codes, or in the
absence of local codes, with:
1) The National Electrical CodeANSI/NFPA No. 70-latest
Edition, or 2) CSA STD. C22.1 “Canadian Electrical Code
- Part 1”. This appliance must be electrically grounded in
accordance with these codes.

1.3 ApplianceOverview
The Bradford White Brute is offered in both
Indoor and Outdoor models for all sizes. The physical
appearance of the Indoor and Outdoor Brutes is
drastically different because the Outdoor model offers a
fully weathertight enclosure that hides the touchscreen.
Whereas the indoor model is not fully weathertight and
the touchscreen can be accessed without having to open
the unit. See Figure 1 through Figure 11.
Both variations of the Brute have the On/Off switch
on the outside of the unit.
Both units have the Rating Plate on the outside
panel to the right. See Figure 2 and Figure 3

The only component (interior) difference between the
Indoor and Outdoor models is that all of the piping for the
Outdoor model, with the exception of the exhaust vent, is
at the BACK of the unit. See Figure 3
The gas connection, the air inlet, and the water inlet and
outlet are all at the back of the unit. This is consistent for
all sizes.
