ECR International PSB-5D Textured Painted Cast Iron Polymouth Gas Fired Steam Boiler, 82% Natural/80.6% LP Gas AFUE, 175K BTU Natural, 107K BTU LP

• Dependable cast iron heat exchanger with cast iron push nipples
• The sections and push nipples expand at the same rate when heated
• By using similar materials instead of less expensive gaskets, the boiler maintains a water tight seal over time
• LWCO (probe type), pressure high limit control, pressure gauge and glass water level gauge
• Completely installed and wired gas control system consist - titanium composite burners, gas manifold with orifices, automatic redundant combination gas valve, 24 volt with pilot filter and regulator, intermittent pilot control, continuous retry 100% shut-off, combination pilot burner/electrode/flame sensor and integral draft diverter
• Atmospheric chimney vent boiler with integral draft hood and vent damper
• Low profile compact design makes it ideal for low clearance installations
• Brass/copper pig tail siphon for long life
• 24 volt transformer
• Flame roll-out safety shut-off fuse link and blocked vent safety shut-off, manual reset disc thermostat (spill switch) with spare fuse link included
• Assembled boiler with insulated jacket, 3/4" boiler drain valve, 15 psi ASME pop safety valve, (2) 2-1/2" supply tappings and (2) 2-1/2" return tappings (2) 2-1/2" square head pipe plugs - to plug unused supply and return tappings
• 12 years cast to last limited warranty
