Page 8 BRADFORD WHITE CORP. Section 2 LOCATING THE APPLIANCE 2.1 General Information The Brute Elite unit is designed for indoor installations only. The appliance should be located to provide clearances on all sides for maintenance and inspection. It should not be located in an area where leakage of any connections will result in damage to the area adjacent to the appliance or to lower floors of the structure.
Page 9 BRUTE ELITE Section 3 VENTING AND COMBUSTION AIR Method 1: Two permanent openings, one commencing within 12” (300mm) of the top and one commencing within 12” (300mm) of the bottom, of the enclosure shall be provided. The openings shall communicate directly, or by ducts, with the outdoors or spaces that freely communicate with the outdoors.
Page 10 BRADFORD WHITE CORP. Other methods of introducing combustion and ventilation air are acceptable, providing they conform to the requirements in the applicable codes listed above. In Canada, consult local building and safety codes or, in absence of such requirements, follow CAN/CSA B149. Ducted Combustion Air The combustion air can be taken through the wall, or through the roof.
Page 11 BRUTE ELITE All installations should be done following the vent supplier’s recommended installation techniques. If manufacturer’s instructions are not available for the material used, follow the Bradford White recommendations. The vent pipe must pitch upward, toward the vent terminal, not less than 1/4” per foot, so that condensate will run back to the Brute Elite to drain. Route vent pipe to the heater as directly as possible.

Be sure to install and terminate both vent and combustion air pipes per the Venting and Combustion Air section of the Brute Elite instructions. BRADFORD WHITE CORP. damage by accident or vandalism. It must be at least 7 feet (2.1m) above a public walkway. 3. Locate the combustion air terminal so that it cannot be blocked by snow.

Section 6B covers BNTV models, which are designed exclusively for “volume water” domestic hot water applications. Refer to the proper section for instructions on installing and piping your product. Refer to Table 9 for the connection pipe sizes required. 6A.
Page 18 6A.3 Condensate Drain A condensate drain trap is built into the Brute Elite unit. Connect a 3/4” PVC pipe between the drain connection and a floor drain (or a condensate pump if a floor drain is not accessible). The condensate drain must be installed so as to prevent accumulation of condensate. When a condensate pump is not used, the tubing must continuously slope downward toward the drain with no spiraling. Consult local codes for the proper disposal method for the condensate.

Page 37 BRUTE ELITE Caution The supply voltage to the Brute Elite unit must not be disconnected, except for service or isolation, or unless otherwise instructed by procedures outlined in this manual. To signal a call for heat, use the 24V field interlock, as shown in the wiring diagram. DO NOT MAKE AND BREAK THE LINE VOLTAGE TO THE Brute Elite UNIT TO SIGNAL A CALL FOR HEAT. A call for heat/ end call for heat MUST be connected to the field interlock terminals.
Page 38 BRADFORD WHITE CORP. Section 8C DETAILED SETUP INSTRUCTIONS and DIAGRAMS Section 8 is divided into three parts. Section 8A includes instructions for using the Quick Start Menu. Section 8B covers basic installation and wiring.

Page 39 BRUTE ELITE • As the temperature begins to rise above 32°F, the Outdoor Reset function causes the setpoint to be lowered. At these warmer temperatures, the heating load on the system is not as great, so the system does not have to reach as high a temperature to handle the load. • As you can see from the display, at an outdoor temperature of about 70°F, the system stops adjusting the setpoint. Above 70°F, the setpoint is constant at 100°F (or another value that you choose).

Page 41 BRUTE ELITE DHW Temperature Setting Regardless of the type of DHW setup, the setpoint adjustment is made the same way. How to get there: From the “Home” screen, press “I” to go to “Info/ Install.” Choose “Advanced Setup,” then go to “DHW Setpoint.” Hydronic Heating with Domestic Hot Water (DHW) Priority When using the Brute Elite for hydronic heating with domestic hot water priority, a call for heat must be supplied to the “T-T or Interlock” terminal.
Page 42 BRADFORD WHITE CORP. Boiler Pump Interrupt Function The Boiler pump interrupt feature is used in some applications when the boiler is being used for both hydronic and domestic hot water heating. The interrupt jumper is used to turn off the boiler pump during a domestic hot water demand. For this to work properly the system must be plumbed and pumped to allow the DHW pump to supply the flow and head requirements for both the boiler and indirect water heater.

Refer to local codes and the make-up water valve manufacturer’s instructions as to whether the make-up water valve should be left open or closed. 9.1 Filling the Boiler System 16. After placing the unit in operation, the ignition system safety shutoff device must be tested. 1. 2.

The Brute Elite unit will begin the start sequence. The blower and pump will energize for the pre-purge period, then the ignition sequence will start. After all safety devices have been verified, the gas valve will open.
Page 52 BRADFORD WHITE CORP.
Page 53 BRUTE ELITE 9.4 Shutting Down the Brute Elite Unit 1. Turn off the main electrical disconnect switch. 2. Close all manual gas valves. 3. If you think the Brute Elite unit might freeze, drain it. All water must be removed from the heat exchanger, or damage from freezing may occur. Also be sure to protect the piping in the building from freezing. Caution This step must be performed by a qualified service person. 9.
Page 54 Section 10 MAINTENANCE WARNING Disconnect all power to the appliance before attempting any service. Contact with electricity can result in severe injury or death. 10.1 System Maintenance Do this once a year, unless otherwise noted. 1. Lubricate the system water-circulating pump, if required, per the instructions on the pump. 2. If a strainer is employed in a pressure reducing valve or the piping, clean it every six moBNTHs. 3.
Page 55 BRUTE ELITE the control. If control replacement is required, turn off all power to the appliance and shut off all manual gas valves to the appliance. Remove the front door to the appliance and the plastic bezel and the control panel. Remove all wire connections from the control board. The control board connections are keyed to only allow connection in the proper location, but proper handling techniques should be used to avoid damage to the wiring or connectors.
Page 56 Transformer with Integral Circuit Breaker The appliance has a 24Vac transformer with integral 4 amp circuit breaker installed to supply the control voltage required for the appliance. The transformer is sized to provide power for the Brute Elite unit only, and should not be used to supply power to additional field devices. If additional loads are added, or a short occurs during installation, the integral circuit breaker may trip.
Page 57 BRUTE ELITE 12. Place the appliance in operation according to the instructions in Section 10. Check all gas connections for leaks. Confirm that all fasteners are tight. NT size (mbtu) Kit number 80 CA006201 105 CA006202 Optional Gas Pressure Switches 150 CA006203 The high and low gas pressure switches are 24V manual reset switches that act to cut power to the gas valves if the gas pressure is too low or too high for proper operation.
Page 58 Section 11 OPERATING DETAILS AND TROUBLESHOOTING 11.1 BRADFORD WHITE CORP. 5. There is a pre-ignition time of two seconds to check the flame sensor operation and status. During this period an intermittent spark can be seen. 6. Next there is a trial for ignition period of four seconds. The direct spark ignition switches to constant spark for three seconds. During this time the gas valve is open.
Page 59 BRUTE ELITE 11.5 Anti-Short-Cycle (ASC) Because the Brute Elite unit is a modulating boiler, and its input will decrease when there is a reduction in the heating load, short cycling is greatly reduced. If the heating load drops below the minimum input of the boiler for an extended period, the boiler will have a tendency to short cycle. This can be a symptom of improper control strategy or setpoints, or a load distribution problem.
