The modern design and attractive appearance of the models BW4 and BW5 Oil-Fired Water Boilers make them ideal for installation in any area. The boilers are shipped fully assembled and wired, including all controls except barometric regulator and circulator pump. The compact 22-gauge steel cabinet has a baked-on enamel paint finish for durability. A 1-in. layer of thermal insulation is applied inside the jacket for protection and thermal efficiency. The flame retention head burner provides efficient fuel usage. A wet base cast iron block with thermal pins surrounds the combustion area for better heat transfer from flue gases to water.
FEATURES RANGE OF CAPACITIES - BW4 and BW5 boilers are available in sizes 91,000 to 245,000 BTUH. An additional nozzle is included to fire the boiler at the next lowest input. Low-fire accessory kits are required to fire the boilers with Beckett burners at the 91,000 and 126,000 BTUH input rate. 2012 DOE COMPLIANT - The BW4/BW5 oil-fired boilers meet all 2012 Department of Energy (DoE) requirements for these products. BAROMETRIC DRAFT CONTROL - The factory-supplied barometric draft control can easily be installed in the vent pipe for optimum draft and combustion efficiency. CONTROLS - Factory-wired controls on units with tankless hot water coil include a triple aquastat relay with high/low limit protection and circulator control. A factory accessory kit is available for protection against low water operation which is required by code. COMBINATION TRANSFORMER AQUASTAT - A 24-v transformer is combined with the aquastat assembly. The transformer will supply power efficient to power a 3-zone system on BW5 models. These units also feature a factory-installed combination pressure/ temperature gauge and a pressure relief valve. COIL OPTIONS - Units are available with or without tankless heater coil. The coil provides a supply of hot water for normal domestic purposes or an accessory tankless heater coil can be added later. FACTORY INSTALLED FEATURES - A factory-installed drain is provided should the boiler ever need to be drained. Oil primary control prevents boiler operation in the event of flame loss. SECTIONS TESTED - Each section is hydrostatically tested to 50 psig. Individual sections are tested to 125 psig at factory. Assembled sections are tested to 75 psig at the factory. The maximum allowable pressure is 50 psig for hot water boilers. EASE OF INSTALLATION - Circulator is shipped pre-wired with 6 ft BX conduit for easy installation for supply-side pumping. SOLENOID OIL VALVE - This provides cleaner burning and quieter operation. Valve is included on all burner types. SWING BURNER DOOR - This unique design offers uninhibited access for set-ups, service, and maintaining the burner. Routine cleaning is also much easier.
