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.

relief valve is included with each Brute. Some Brutes may
require that the PRV be installed prior to lling the system.
