B.Boiler construction

•Boiler sections

•Assembled with short, individual draw rods.

•Cast with sealing grooves for high temperature sealing rope to assure permanent gas- tight seal.

•Sealed water-tight by elastomer sealing rings, not cast iron nipples. Each port opening is machined to completely capture sealing ring between sections.

•Must be hydro-wall design to provide completely water-cooled combustion chamber.

•Provided with sufficient tappings to install required controls.

•Limited 10 year warranty against workmanship and defects to be in writing by manufacturer.

C.Boiler(s)

•Provided with cast-in air elimination to separate air from circulating water.

•Provided with expansion tank tapping to divert separated air to expansion tank.

•Constructed to provide balanced water flow through entire section assembly using single supply and return connections for water. No external headers are necessary for water. Steam requires two supplies to an external header 24” minimum from the waterline to the bottom of the header.

•Designed with a low silhouette to provide maximum headroom.

•Furnished with insulated burner mounting plate having necessary holes and tappings to mount burner. High temperature sealing rope is used to provide permanent gas- tight seal between front section and plate.

•Furnished with two observation ports (one in front and one in back) to allow visual inspection of the flame.
