Biasi 3Pass Cast Iron Boiler Featured Product
Biasi Oil Fired 3Pass Boiler






A 3-pass boiler design is the most efficient way to get the maximum amount of heat from the fuel, since it contains three times as much interior surface area (compared to a single-pass boiler) to extract heat from.


Technical Advantages
  • Gas or oil burner compatible
  • Easy access swing door
  • May be direct vented with no flue required; can be direct vented outdoors with optional direct vent kit.
  • Low water content boiler heats up faster with less fuel
  • Efficient 3-pass heat exchanger boiler design
  • GG20 cast-iron construction for superior heat retention and durability
  • ASME, UL, and IBR listed
  • 58 psi cast-iron construction

The B-10 boiler systems have been heating residential and commercial buildings throughout the world for years. It has proven its fuel efficiency and durability in countries where fuel can cost up to four times as much as in the U.S. The same fuel saving technology is now available here in North America. With the three pass boiler design and low water content, heat is quickly supplied for your heating zones and hot water needs. Combined with an outdoor reset control, you can achieve a fuel savings of up to 40% over conventional single pass boilers. You will also have peace of mind since the B-10 boiler package complies with ASME and UL standards and is IBR rated. The B-10 boiler system is the cost-competitive heat and hot water system of choice.

 Duct Smoke Detectors
Universal Voltage Models
230 VAC, 115 VAC, 24 VAC or 24 VDC operation
2650-560 Ionization • 2650-561 Photoelectric

Firex® duct smoke detectors provide early detection of smoke and products of combustion present in air moving through an HVAC duct. These devices are designed for prevention of smoke recirculation in areas by the air handling systems. Fans, blowers, and complete systems may be shut down in the event of smoke detection. Universal voltage models will operate on any one of four input voltages (230 VAC, 115 VAC, 24 VAC or 24 VDC).
Firex® duct smoke detectors are available with either an ionization detector head (2650-560) or a photoelectric detector head (2650-561).  Each duct smoke detector contains two form “C” alarm contacts and one form “C” trouble contact.  Visual indicators are mounted on the housing front for ease of pilot and alarm status indication from high mounting locations. A manual test/reset switch is also provided on the front of the detector to make frequent testing easy.


Air sampling is accomplished by two tubes, which protrude into the duct.  An exhaust tube of one standard length (7'') is provided with each Firex duct
smoke detector. Intake sampling tubes, which must be ordered separately, are available in three standard lengths.  Duct smoke detector mounting is accomplished by the use of a mounting template and four sheet metal screws, which are provided. Also available are special UL 50 listed, NEMA 3R weatherproof enclosure (Model 0590) which can be used in appropriate outdoor or indoor applications for protection from the elements.
