Section 1
GENERAL INFORMATION
1.1 Introduction
This manual includes information which will help
you to install, operate, and maintain the Brute Elite
1000 and 1700 systems. Please read this manual
completely before proceeding with the installation.
If you have any questions regarding this equipment,
please consult the Bradford White factory, or a local
factory representative. Many operating problems are
caused by improper installation.
WARNING
Brute Elite’s must be installed in accordance
with the procedures detailed in this manual,
or the Bradford White Corporation 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 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.

1.2 About the Brute Elite Control
System
This unit includes an advanced control system
which can perform many functions. This is part of
the reason why the Brute Elite 1000 or 1700 can
deliver such outstanding performance. There are
several “branches” in the control software, and many
different display screens. For clarity, throughout
this manual we have made a special effort to show
you how to reach each of the important setup and
operating functions. We have done this in two ways:
• In many cases, we have shown you the actual
screen display you will see while performing a
function.
• Sometimes, instead of showing the screens, we
have just listed the series of choices you should
make in order to reach the section you want.
The arrangement of the control software is actually
quite logical, and after you have worked with it a bit,
you will not have any problems “nding your way
around.” We just want to give you some help with
the rst part of the process, when you are “getting
used to” the control system.
Later in this manual, we will detail information on
the setup and operating procedures. There are a
couple of concepts you will need to understand right
from the start.
• Each boiler has two controllers and two
burners, as shown in Fig. 1. A single Operator
Interface is used to communicate with both
controllers.

Boiler 1
Fig. 1 – Control Arrangement in a Single-Boiler
Installation
Each controller and burner work together. Each
boiler includes two of these controller/burner
combinations.
Notice the different terms we are using here.
The term boiler refers to the whole unit – the
complete Brute Elite 1000 or 1700. Each
boiler includes two separate controller/burner
pairs.
• Brute Elite 1000 and 1700 units are always set
up for “Lead/Lag” operation. The term “Lead/
Lag” means that, as the heating load increases,
the control system brings additional burners on
automatically.
On a multiple-boiler installation, each of the
individual boilers is still set up as shown in Fig.
1 above. The controller/burner pairs on all of the
boilers are arranged in a “daisy chain.” Up to four
boilers, with up to eight controller/burner pairs, can
be connected in this way. See Fig. 2.
Fig. 2 – Lead/Lag Arrangement in a Multiple-
Boiler Installation
In a multiple-boiler installation, just one of the
operator interfaces is active. It can communicate
with all of the controller/burner pairs in the system,
so it displays information from all of the burners. A
single system sensor provides the control input for
the system.
Actually, even a Brute Elite 1000 or 1700 unit set
up as a single boiler still uses Lead/Lag operation.
If the heating load becomes too great for the rst
burner, the control system automatically starts the

second burner.
To work with this control system, you will need
to understand the difference between two kinds of
control functions:
• Some of the functions control all of the
controller/burner pairs, working together as
part of the Lead/Lag system. As an example,
the setpoint for a whole multiple-boiler system
is set by a single value: “Central Heat Lead/
Lag Setpoint.” By changing this one value,
you change the setpoint used by the whole
system. The action of all of the controller/
burner pairs will refer back to that single value.
On the Operator Interface, from the Home
screen you can reach all of the Lead/Lag
functions by pressing the View Lead Lag
button. See Fig. 3.
• Other functions apply only to each separate
controller/burner pair. As an example, each
controller/burner has a name, and this can be
changed.
The Home screen on the Operator Interface
will show icons for each of the controller/
burner pairs connected to the system. To
reach one of the functions for an individual
controller/burner, press the icon for that
controller/burner. On the following screen,
press the Congure button. This will take
you to all of the conguration options for that
individual controller/burner.
Fig. 3 – Going to Lead/Lag and Individual
Functions
Note – For individual functions, if you want to make
a change on all of the controller/burner pairs in the
system, you will have to go to each controller/burner
separately and repeat the change for each of them.
If there are eight controller/burners in the system,
and you want to make the same change on all of
them, go to each of the eight controller/burner pairs
separately.
As we go through the explanations in this manual,
we will point out whether a control function affects
the whole Lead/Lag system, or just an individual
controller/burner pair.
This has been just a quick introduction, but this
manual includes two longer sections that will help
you to work with the control system:
• Section 8 – “Using the Controls on the Brute
Elite.”
This is an introduction to the Operator
Interface. It explains how to “get along” with
the interface: how to move through the various
screens, enter and change values, and so on.
• Section 9 – “Setup and Conguration”
The rst part of this section includes a more
complete explanation of the Lead/Lag system.
The rest of the section includes detailed setup
instructions.
If you are not familiar with the control system, the
installation and setup process will go much more
smoothly if you read through these three sections
before beginning work.
1.3 Safety Notes
WARNING
Fire or Explosion Hazard
Improper conguration can cause fuel buildup and
explosion. Improper user operation may result in
property loss, severe physical injury, or death.
Any changes to safety-related conguration
parameters must only be done by experienced and/or
licensed burner/boiler operators and mechanics.
If any odor of gas is detected, or if the gas burner
does not appear to be functioning in a normal
manner, close the main gas shutoff valve. Do not
shut off the power switch. Contact your heating
contractor, gas company, or factory representative.
The Brute Elite is protected against over-
pressurization. A pressure relief valve is included
with each Brute Elite.
The inlet gas pressure to the appliance must not
exceed 13” W.C. (3.2 kPa).
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”

Page 4 Bradford White Corp.
and with the requirement of the local utility or other
authorities having jurisdiction. Such applicable
requirements take precedence over the general
instructions contained herein.
WARNING
Carbon Monoxide Hazard
Improper adjustment of the burners may lead to poor
combustion quality, increasing the amount of carbon
monoxide produced. Excessive carbon monoxide
levels may lead to personal injury or death.
WARNING
Electrical Shock Hazard
Electrical shock can cause severe injury, death or
property damage. Disconnect the power supply
before beginning installation or changing the
wiring to prevent electrical shock or damage to the
equipment. It may be necessary to turn off more than
one power supply disconnect.
All electrical wiring is to be done in accordance with
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.
