FOR YOUR SAFETY
PLEASE READ THIS BEFORE OPERATING
WARNING
If you do not follow these instructions exactly, a fire or explosion may
result, causing property damage, personal injury, or loss of life.
A. This unit does not have a pilot. It is equipped with an ignition device
that automatically lights the burner. Do not try to light the burner by hand.
B. Before operating the unit, check for any smell of gas in the area around
it. Be sure to smell next to the floor, because some gas is heavier than air
and will settle near the floor.
C. Use only your hand to turn the handle on the gas valve. Never use tools. If
the valve handle will not turn by hand, don’t try to repair it. Call a
qualified service technician. If you force the valve or try to repair it, this
may result in a fire or explosion.
D. Do not use this unit if any part has been under water. Immediately call a
qualified service technician to inspect the unit. Any part of the control
system or any gas control which has been under water must be replaced.
WHAT TO DO IF YOU SMELL GAS

SHUTTING DOWN THE BRADFORD WHITE BRUTE
It may sometimes be necessary to shut down the Bradford White Brute. Here are
the steps required to do this:
- Switch off the main electrical disconnect switch.
- Open the front cover and close the main manual gas valve.
- If freezing is anticipated, drain the Bradford White Brute. (Also be sure to protect the piping in the building from freezing.)
The steps listed above may require qualified service personnel.
RESTARTING THE BRADFORD WHITE BRUTE
It may be necessary to restart the Bradford White Brute – for example, after a
power interruption. Here are the steps required to do this:
- Reset any errors using the user interface. See the section on “About Lockouts, Holds, and Alerts.”
- Turn up the thermostat to call for heat.
- In approximately 2 seconds, the blower will operate. Ignition should occur after 35-40 seconds. It may take as long as 2-1/2 minutes.
- If ignition does not occur, wait 5 minutes and then repeat steps 1 through 3.
- If, after three attempts, the unit still does not light, shut down the boiler and call your service technician.
If the unit has been drained, follow these steps:
- See the “Installation and Operation Manual” for instructions on filling and purging the unit.
- Remove the front door. Turn on the gas shutoff valve.
- Switch on the main electrical disconnect switch. The pump and blower will start, and the igniter will be energized. After 35 seconds the gas valve will be energized, and ignition will occur. If ignition does not occur within 2-1/2 minutes switch “off” the main disconnect switch, wait 5 minutes and switch it “on” again. If after three attempts
ignition does not occur, shut down the unit and call for service.
IN THE EVENT OF POWER FAILURE
The Bradford White Brute will not operate during an electrical power outage. If there is an extended power outage with the danger of freezing, then the Bradford White Brute (and all other water systems) should be completely drained. Before draining the unit, turn off the gas and turn off the main power switch. When you replace the unit in service, refer to the “Installation and Operation Manual” for instructions on filling and purging.
THE USER INTERFACE AND ON/OFF SWITCH
The Bradford White Brute has two control components:
- the User Interface or HMI (“Human/ Machine Interface”).
- the On/Off switch
The User Interface (HMI) is used to send commands to the boiler controller and to display operating and setup information sent from the boiler controller.
The drawing below shows the main parts of the user interface (HMI), and the following table lists the functions of the various parts of the user interface (HMI).
Up/ Down Arrow buttons| Use these to go to the choice you want to select in
the display area, then press the round OK button.
---|---
Left/ Right Arrow buttons| Use these to go to the choice you want to select in
the display area, then press the round OK button.
Back button | Use this to go back to the previous display.
Info/ Install button | Press this button at any time to go to the sub-menus
that allow you to set up and monitor the controller.
Home button | Press this button at any time to go back to the Home display.
(See the section on “Home Display.”)
Round OK button | Use the round OK button to confirm a value or action.
Button Functions on User Interface
Home Screen Button
When the boiler is operating normally, the boiler controller will display the
Home Screen on the display. Or you can press the Home Screen Button at any
time to get to this Home Screen.
The Home Screen has three sections:
-
The upper section of this screen shows the most important operating information. In this example, the display is showing the system setpoint, the operating temperature,
the outlet and inlet temperatures for the water entering and leaving the boiler, and the outdoor temperature.
(Note that the five lines at the top of the screen are customizable, and may be arranged differently on your system.) -
The central section shows some additional operating and setup information. In this case, this area lists the boiler name, boiler state, current demand, and the current password level (the “access status”).
-
The lower section shows any current lockouts, holds, or alerts.
Info/Install Button
The Info/Install Button will change the display to show the six sub-menus
available.
- To move from one choice to another, use the Left- and Right-Arrow buttons or the Up- and Down-Arrow buttons.
- Once you have highlighted the choice you want, press the round OK button.
Here are the functions you can reach from the Info/ Install display screen:
Quick Start| This menu gives you an easy way to check or change the most
common settings on the unit.
---|---
Login| If you want to change a setup value or function, and the system
requires a password, you can enter it here.
Test| These parameters let you turn the burner on and off, and control the fan
and pump speeds.
Advanced Setup| The sub-menus listed here allow you to set up most of the
functions on the controller.
Diagnostics| Use the Diagnostics to check the status of the sensors and the
digital inputs and outputs. The system also records a history of lockouts and
alarms.
Display Setup| You can use this option to adjust the contrast of the display
or change the items which appear at the top of the Home display.
Quick Start Menu (found in the Info/Install Screen)
Once the unit has been installed and set up, the Quick Start menu provides a
simple way to change the most common settings used in a typical installation.
Example – Changing the CH (Central Heat) Setpoint
- On the Quick Start menu, use the Up- and Down-Arrows to go to the line for CH Setpoint. Press the large OK button to select the line.
- Use the Up- and Down-Arrow buttons to select the value you want.
- Press the round OK button to enter the new value.
ABOUT LOCKOUTS, HOLDS, AND ALERTS
The system responds to three kinds of trouble indications:
- A” lockout” is caused by a serious problem that might involve a safety issue. Once the controller enters a lockout, the burner will shut down, and will not be allowed to run again until the cause of the problem is corrected, and you reset the control system.
- The system may enter a “hold” for a period of time before locking out. This allows the controller to see if the error becomes resolved prior to the hard lockout.
- An “alert” indicates that some feature of the control system’s operation was not correct, delayed, or waiting for a response. This does not necessarily indicate a problem.
If a problem occurs, the system will present a note across the bottom of the screen:
Correct the problem, then press the round OK button to reset the control.
Each error message includes a number. For a more detailed description of each
message, see the “Installation and Operation Manual.”
GENERAL CARE
Keep the area around the Bradford White Brute clear and free from combustible
materials, gasoline, and other flammable vapors and liquids. Clean the jacket
surfaces with a damp cloth and mild soap. Do not use flammable cleaning
materials. Keep the vent terminal free of obstructions. Do not pile snow
against the vent terminal.
ANNUAL INSPECTION AND SERVICE
You should visually inspect the vent pipe once a year. Should any corrosion or
leaks exist, have the affected parts replaced.
Once each year a qualified service agency should conduct a detailed inspection
of all flue product carrying areas of the boiler and vent system. Follow the
service instructions in
the “Installation and Operating Instructions Manual” for the Bradford White
Brute.
Caution
Do not use this boiler if any part has been under water.
Immediately call a qualified service technician to inspect the boiler. Any
part of the control system and any gas control which has been under water must
be replaced.
WARNING
If the unit overheats or the gas supply fails to shut off, do not turn off or
disconnect the electrical supply to the pump.
Instead, shut off the gas supply at a location external to the Bradford White
Brute.
