Brute BOILERS AND VOLUME WATER HEATERS

FAMILIARIZING YOURSELF TO THE

The Bradford White Brute is offered in both Indoor and Outdoor models for all sizes, as both Boiler and Volume Water Heater. The appearance of the Indoor and Outdoor rates is drastically different as the Outdoor model has a weathertight door that covers the entire front of the unit. This weathertight door must be unlatched, lifted off, and set aside for all adjustments and servicing.

The only component and interior difference between the Indoor and Outdoor models is that all of the piping for the Outdoor model, with the exception of the Exhaust Vent, is at the BACK of the unit. See Figure 1
The gas connection, the air inlet, and the water inlet and outlet are all at the back of the outdoor unit. This is consistant for all sizes.

Sizes available are 150-850 MBTU/h. This illustration is of the 150 MBTU/h For complete details to all sizes and dimensions, please refer to the Brute Install and Operating Manual, Doc #1344

Using the Touch Screen

Figure 39. Brute with Touch Screen
The Touch Screen
The Touch Screen is located front and center on the Brute and allows you to navigate into all of the functionality and control that is available to setup and customize your heating and/or hot water system.
Using the Touch Screen
A screen saver is programmed into the display. Simply touch the screen to wake it up. While under normal operation, the Touch Screen will automatically present this Home Screen. See Menu 1

The home screen shows a picture of the Brute controller. The color of the controller depends on the status of the Brute, as shown below.

Figure 40. Boiler Status Colors
To check the operation of the appliance, press the large Control Icon on the Home screen. The system will present a Status Summary screen for the appliance:

Screen Menu Icons

Sometimes a screen is used to present a list, and often the list is too long to present on a single screen view. To see the rest of the list, pull down the bar on the right side of the screen, or use the up-and-down arrows. To make a change, or to get more information about one of the items on the list, press the line for that item.

Login (required for some parameters)
To change some parameters, a Login (password) is required. The control system includes three levels of password protection:

OEM| Factory Password Setup and parameter changes are Available only to the factory.
---|---
Login| Installer Password Setup and parameter changes made when the system is installed, and some diagnostic and troubleshooting functions. The installer level password is “lnt” (lower case “LNT.”) See Menu 3
User| (no password required)
Non-critical adjustments and functions, including adjusting the Central Heat and Domestic Hot Water setpoints, monitoring the input and output variables, reading parameters from the controller, and reading the error log (For some special safety-related functions, besides entering the correct password, the system will ask you to go through an additional “verification” process. For more information, see the section on “Configuration.”)

When a password is necessary, the system will present the keyboard screen. See Menu 3.

Menu 3. Keyboard Screen

The passwords used by this system are “case sensitive” – it matters whether a letter in the password is capitalized or not. Pressing the Shift key toggles between capital and lower case letters. “BS” stands for “Back Space,” and also works as a Delete key. Anyone can view all of the parameters. However, to change most of the parameters, you will need a
password.
At the bottom of the screen, the system indicates that you need to enter a password.

Menu 4. Login Required

The screen used to log in is similar to the Keyboard screen.
It may be difficult for some operators to press the keys on this screen. In this case, use the back of a plastic pen, or a stylus, or a pencil eraser. (Do not use sharp metal tools – these may damage the plastic surface of the screen.)
Each time you press a key, the system will respond with a beep. If you are entering a password, an asterisk (*) will appear for each character you enter. The beeps and asterisks will help you enter the correct number of characters for your password. When changing a numerical value, the system presents a numerical entry screen, as shown below.

Menu 5. Numeric Entry Screen

Verification Process for SafetyRelated Parameters

The verification process allows the user to confirm that all the changes made are correct and that there have not been any inadvertent changes made.

1. When you start to change a parameter that is related to safety, the system will present a warning which looks like this:
   Menu 6. Parameter Safety Warning
   WARNING
   Changing safety parameters should only be conducted by experienced, licensed boiler operators and mechanics. Hazardous burner conditions can happen with improper operations that may result in PROPERTY LOSS, PHYSICAL INJURY, or DEATH.
   Press OK to continue. The system will ask you to log in before you make a change. (For more information on logging in, see Section 8.2.)

2. If you make a change in any group that could affect the safe operation of the unit, the control system will ask you to “verify” the change before it is accepted.

3. Once all parameters have been changed, return to the configure menu. In the lower right-hand corner of the screen, you will see ‘VERIFY’ Press VERIFY, then press BEGIN to start verification.
   Notes –
   • Once you change one of these safety-related parameters, you must finish the verification process for the group that includes the parameter, or the control system will not let the boiler operate. You can wait to do the verification until you have changed parameters in other groups, but before you return the boiler to service, you must complete the verification process for all groups that have been changed.
   • At the end of the verification process, you must press the Reset button on the front of the controller. See Figure 41. You have to do this within 30 seconds, or the verification will be canceled. To make it easy to reach the Reset button, open the door on the front of the boiler and slide out the control panel before beginning the verifi cation.
   Figure 41. Reset Button on Controller

4. The system will present a listing for each group of parameters that need verification See Menu 7.
   Menu 7. Safety Parameter Confi rmation

5. For each group, check the list carefully. Press Yes if all of the parameters in the group have been entered correctly. For each group, you are given 30 seconds to select Yes/No. A count-down timer is shown at the bottom of the screen.
   If you made changes in other safety-related groups, verify the entries in those groups in the same way. Do this until the following screen shows
   Menu 8. Safety Parameter Reset

6. When the process is complete, the system will tell you to reset the control system. The Reset button is located on the front of the controller. You must press the Reset button within 30 seconds or the verification will be canceled. A count-down timer is shown at the bottom of the screen.
