BOILER CONNECTION WATER CONNECTION The hard water reaches the conditioning plant. This must be surrounded by dividing wall; the floor should possibly be made in “gres”; independent drain for backwashing the conditioner. When the softened water leaves the conditioner it must then be forwarded to the purified water and condensate collecting tank. - Page 14 FUEL CONNECTION (see also burner instruction book) These may be three types: a - pipings for light oil (gas oil); b - pipings for heavy oil (fuel oil); c - pipings for gas. Gas oil pipings The pipings conveying oil from the tank to the pump and viceversa, must be made with welded fittings for iron pipings and biconical fittings for copper ones.
