Thermo-Dynamics Oil Fired Water Boiler, Series: HT-I, HT-90/110 Model, 84.2 - 85.1 % AFUE, 126 - 154 MBH Input, 109 - 132 MBH Heating BTU, 95 - 115 MBH Net BTU Rating, 0.9 - 1.1 gal/hr, 1-1/4 in Supply/Return Connection, Oil Fuel, Forced Draft Vent, Beckett AFG Burner, 5 gal/min Tankless Heater Rating, Steel, Powder-Coated, 22-1/2 in W x 37-7/16 in H x 31-3/4 in D

• A wet-base design, a horizontal tube and a 3-pass heat exchanger make this one of the most efficient boiler designs available
• A 5 gal/min tankless coil with a 30 gal boiler water content assures abundant hot water
• Forced draft burner eliminates chimney draft problems
• Multiple firing rates on the same unit
• One-piece boiler construction ensures years of trouble-free service and there are no push nipples or O-rings to leak
• Heat exchanger easily accessible for cleaning
• The 85% AFUE rating is among the highest department of energy (DOE) ratings
• Due to the horizontal tube and wet-base, the HT is remarkably quiet, the unit-flow path of combustion gases allows for smoother, quieter combustion than firebox, wet-leg designed boilers
• Each boiler is constructed and hydrostatically tested in accordance with ASME boiler code, the capacity and efficiency are rated in accordance with the standards of the institute of boiler and radiator manufacturers (IBR)
• Limited lifetime warranty
• Built-in air scoop purges air from the system providing a quiet, trouble-free hot water heating system without the use of external devices
• Extended flange coil is away from the boiler for easy accessibility, use of ribbed neck carriage bolts eliminates the problems encountered when a weld stud is broken during servicing, large coil plate allows for a greater gasket sealing area
• Weld fittings extend beyond the jacket and allow the service technician or homeowner to see small leaks that, if undetected, could later damage the boiler shell and potentially void the warranty
• Easy cleaning and maintenance accessibility to combustion areas and the open tubes make it easy for the service technician to thoroughly clean the boiler
• No tight, pin-type passage ways with hidden nooks and crannies, making a thorough cleaning possible
• A well-maintained boiler continues to perform at higher efficiency and is less likely to develop service problems
• Factory-mounted/wired burner and controls
• Fully insulated heat exchanger with powder-coated cabinet
• Equipped with triple aquastat, circulator and temperature/altitude gauge
• (2) 1-1/2 in return
