An integral draft diverter protects against harmful back drafts to ensure safe operation. Low water cut-off, pressure limit control and pop safety valve are also standard safety features. The 1605HSID Boiler incorporates a 6\" steam chest which allows the boiler to generate ample amounts of steam. The 2 1\/2\" supply tappings provide easy access for steam to enter the distribution system and heat your home quickly.\u003cbr\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eExceptional Heat Exchanger Design: Features a dependable cast iron heat exchanger with cast iron push nipple connections. 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.\u003c\/li\u003e\n\u003cli\u003eCycleGard CG400 LWCO: CycleGard low water cut-off is equipped with an Intermittent Level Test. This important feature adds protection against false signals that can be caused by foam and volatile water conditions inside the boiler. The Intermittent Level Test removes power from the burner at preset intervals. During the test, foam dissipates and the water level stabilizes - allowing CycleGard to monitor the true water level in the boiler assuring safe and accurate operation.\u003c\/li\u003e\n\u003cli\u003eWarranty: 10 Year Limited Heat Exchanger\u003c\/li\u003e\n\u003cli\u003eWater Return\/Supply: (2) 2-1\/2\" NPT\u003c\/li\u003e\n\u003cli\u003eGas Inlet: 1\/2\" NPT\u003c\/li\u003e\n\u003cli\u003e120 Volts AC, 60 hertz, 1 phase, less than 12 amps (15 amp circuit recommended)\u003c\/li\u003e\n\u003cli\u003e150,000 BTU Input\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/penncoboilers.com\/sites\/default\/files\/240009892%20Pennco%2016%20Sell%20Sheet%2005-16-23%20WEB.pdf\" target=\"_blank\"\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003eProduct Brochure\u003c\/span\u003e\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/penncoboilers.com\/sites\/default\/files\/1305004%20REV%20P.pdf\" target=\"_blank\"\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003eInstallation and Maintenance Manual\u003c\/span\u003e\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/penncoboilers.com\/sites\/default\/files\/240013734%20PENNCO%2016%20PARTS%20REV%20A.pdf\" target=\"_blank\"\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003eParts List\u003c\/span\u003e\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/penncoboilers.com\/sites\/default\/files\/240013741%20REV%20A.pdf\" target=\"_blank\"\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003eUser Manual\u003c\/span\u003e\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/penncoboilers.com\/sites\/default\/files\/240013158_Pennco%20Consolidated%20Warranty%20-%20October%202020-B.pdf\" target=\"_blank\"\u003e\u003cspan style=\"text-decoration: underline; color: #0000ff;\"\u003eWarranty\u003c\/span\u003e\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PENNCO BOILERS","offers":[{"title":"Default Title","offer_id":43932323840051,"sku":"PEN1605HSID","price":4012.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/5964\/8563\/files\/pennco_2016_20series.png?v=1769700891"},{"product_id":"pennco-silver-15b-060k-3-zone-59-000-btu-residential-cast-iron-natural-gas-boiler","title":"Pennco Silver 15B-060K 3 Zone 59,000 BTU Residential Cast Iron Natural Gas Boiler","description":"\u003ch2\u003eOptimize Your Home’s Heat with the Pennco Silver 15B‑060K 59,000 BTU Cast‑Iron Hot Water Gas Boiler\u003c\/h2\u003e\n\n\u003cp\u003e\nWant dependable hydronic heat without a bulky footprint?
