ADVANTAGESLGB` DESIGN <br />LGBTM sections are made of durable cast iron for <br />long life. It's not uncommon for Weil-McLaW` cast <br />iron boilers to last 3S years or more. <br />Sections are not face ground; the tough outer skin is <br />retained to protect against corrosion. <br />The sections are <br />studded with heat pins <br />that cause the hot <br />gases to swirl about, <br />scrubbing the entire <br />surface for greater heat <br />transfer and maximum <br />operating efficiency. <br />Sealing rope between the sections assures a <br />permanent, gastight seal. When installed, the rope <br />is visible between sections so the boiler can be <br />checked for tightness. Sealing rope — a standard <br />feature of Weil -McLain' commercial boilers — allows <br />for expansion and contraction of the sections, is <br />impervious to heat and moisture, will not crack and <br />will last the life of the boiler. <br />aLLUGING _ I .' <br />� <br />i,,.,. d„, MACHINED <br />Section Seal SURFACE <br />SEALING <br />Modern elastomer sealingu- <br />..a PING <br />rings in the port openings <br />assure a watertight seal. <br />Because of the elasticity MACHINED <br />of the seals (unlike metal. SURFACE <br />push nipples), theyx " °» <br />fill any gap caused by <br />imperfections in the port openings, misalignment of <br />sections, or expansion and contraction. <br />Combined with short draw rods, sealing rings also <br />permit faster section assembly. Lugs and sockets <br />assure proper section alignment during assembly; <br />the machined surfaces of the port openings control <br />the compression ratio of the rings. <br />Removing the rear <br />jacket panel and steel <br />cleanout plates expose <br />the flue passages <br />for inspection and <br />cleaning. <br />The insulated, galvanized steel base houses the <br />gas manifold and one-piece, high tempurature <br />aluminized steel burners. These burners <br />feature efficient performance, excellent flame <br />characteristics, and quiet ignition and extinction. <br />Burners provide fixed primary air — no adjustment <br />required for approved gases. <br />One burner/base assembly and one gas train are <br />furnished for the LGB1"-4 through 12, and two each <br />for the LGBTI-13 through 23. <br />
