The Model BWB Gas-Fired Hot Water Boiler provides fast heat quietly and economically to assure the finest in hydronic heating. These boilers provide quality design in a small, compact unit easily installed in a basement, garage, or utility room. They can be installed on a combustible floor when an optional combustible floor base is used.The BWB boilers are CSA certified for use with natural gas and are field convertible for use with propane gas when a factory-authorized conversion kit is used.
Range of Capacities - These boilers are available in sizes 45,000 to 295,000 BTUH.
2012 DOE Compliant - The BWB boiler features a Honeywell 2012 DOE compliant High Limit/Electronic Control. The control monitors the water temperature and delays the burner starting until the residual heat has been transferred. This maximizes efficiency
by turning on the burner only when needed.
Completely Packaged - Each boiler is completely assembled, including all controls (except thermostat and expansion tank). All necessary wiring is factory installed, except for the circulator pump. The boiler is ready for gas, water, room thermostat, and electrical connections.
Thermal-Pin, Cast-Iron Sections - These sections speed heat transfer from the flue gases to the boiler water with faster thermostat response, providing greater comfort and economy. Maximum heat is produced at a lower level on the thermal-pin sections, leading to peak efficiency. Steel push nipples are used between each section to provide a water-tight seal.
Integral Draft - These boilers incorporate an integral draft system to simplify installation. A factory-supplied, field-installed draft hood is included.
Titanium Composite Burners - Provide quiet operation, corrosion resistance and improved combustion efficiency. Propane convertible with accessory kit.
Other Controls - An automatic gas valve and intermittent pilot provide quiet dependable operation of the burners. Factory-supplied safety components assure protection against overheating and pressure build-up. A factory-authorized accessory kit is available for protection against low water operation where required by local code. The circulator is pre-wired with 5-ft. (1.5 M) of BX conduit for easy installation for supply-side pumping.
Insulated Casing - The casing is fully insulated with fiberglass for maximum operating efficiency and economy.
Automatic Vent Damper - The BWB boiler is CSA design cerfified for use with the factory supplied automatic vent damper.
Sections Tested - Each section is hydrostatically tested to 50 psig. Individual sections are pressure tested to 125 psig at factory. Assembled sections are pressure tested to 75 psig at the factory. The maximum allowable pressure is 50 psig for a hot water boiler.
