Models BS1 and BS2 Gas-Fired Steam Boilers provide 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 model BS1 and BS2 design is CSA and A.G.A. certified for use with natural and is convertible to propane gas with accessory kit.
FEATURES
RANGE OF CAPACITIES—Sizes 75,000 through 299,000 Btuh input are available.
COMPLETELY PACKAGED—Each boiler is completely assem- bled, including all controls (except room thermostat). All necessary wiring is factory installed. The boiler is ready for gas, water, room thermostat, and electrical connections as shipped.
THERMAL-PIN, CAST-IRON SECTIONS—These sections speed heat transfer from the flue gases to the boiler water, with faster ther- mostat response, providing greater comfort and economy. Max- imum heat is produced at a lower level on the thermal-pin sections, leading to peak efficiency.
TITANIUM COMPOSITE BURNERS—Provide quiet operation, corrosion resistance and improved combustion efficiency. Propane convertible – with accessory kit.
CONTROLS—An automatic gas valve and continuous pilot or intermittent pilot provide quiet, dependable operation of the burners. Factory-installed safety components assure protection against overheating, pressure buildup, and low-water operation.
INSULATED CASING—The casing is fully insulated with fiber- glass for maximum operating efficiency and economy.
AUTOMATIC VENT DAMPER—The Model BS1 and BS2 is designed with automatic vent damper to recover chimney loss during off cycle.
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. Maximum allowable working pressure is 50 psig. The maximum allowable pressure is 15 psig for steam boilers.
INTERGRAL DRAFT—These boilers incorporate an integral draft system to simplify installation. No external draft diverter is needed.
WARRANTY—The cast-iron sections are covered by a non- prorated 12-year warranty on the entire assembly. Vent damper covered by 5-year warranty. All other parts are covered by a 1-year limited warranty.
