Contact SupplierIn order to align the height of the combustion tube and the breech block, ceramic tube insulation (CM162-016) must be placed around the tube at the furnace ends. It is important to note that each furnace requires a slightly different amount of insulation to align the tube with the breech block. The proper amount of bedding is the amount of insulation necessary to align the combustion tube without applying strain on the tube when mounted in the breech block and the furnace top is closed.Build up the combustion tube bedding from the bottom until the combustion tube is slightly above the breech block opening with the breech block in its lowest position. Periodically check the tube bedding is not built up excessively by gently closing the furnace top.Loosen the pedestal base thumbscrew and tighten the pedestal base onto the rail by turning the base clockwise.
