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 CSA B149.1 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. Refer to Figures 1-7 for PRV
locations.
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” 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 Code ANSI/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.
