General Information

1.1 Introduction

This manual provides information necessary for 

the installation, operation, and maintenance of Bradford 

White Corp. Brute Elite appliances. Read it carefully 

before installation.

All application and installation procedures should 

be reviewed completely before proceeding with the 

installation. Consult the Bradford White Corp. 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. 

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.  

WARNING

Brute Elite units 

must

 be installed in accordance with 

the procedures detailed in this manual, or the Bradford 

White Corp. 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 Elite boilers must conform 

to the Standard for Controls and Safety Devices for 

Automatically Fired Boilers, ANSI/ASME CSD-1. Any 

modifications to the boiler, its gas controls, or wiring 

may void the warranty. If field conditions require 

modifications, consult the factory representative before 

initiating such modifications.
