And Much More CGi Series 2 GAS BOILER for Sidewall or Natural Draft Venting (Induced Draft) Water Net Ratings: 37.000 to 169.000 Biu/Hr Design Advantages Cast Iron Sections with Elastomer Sealing Rings Boiler sections are made of durable cast iron for strenglh, efficiency and long life. It's not uncommon far a Weil-McLain cast iron borler to last 35 years or more. The heat pins in the vertical flue passages cause Ihe hot gases la swirl about, covering iho entire surface of each section far maximum heat transfer. Radiation plales, further increase Heat transfer for maximum efficiency. Modern elastomer sealing rings In the porl openings assure a permanent waler-tighl seal. Tfie flexibility and elastic memory of these seals (unlike metal pusii nippies) prevent leate caused by thermal expansion and contraction. A special high-temperature sealanl between boiler sections assures tighlness from gas leakage in the black. High-Grade Stainless Steel Burners European-dtjsiyned, pNyh-yrade; stainiKss ?1t*el burners h^ue internal venturi air flow technology for accurate mixture of Tuel and air Tms provides far maximum efficioncy in fuel usage. These burners arc matfc end rely of stainless steel and designed so the burner ports provide exceptional stability with natural or pmpanegas for quieter operation, longer life and improved combuston Venting Flexibility The CGi boiler has the flexibility to be vented one of two ways ...
