Penetration seal apparatus and method

An apparatus for forming a penetration seal on a heating system component comprising:

• a tubular base plate assembly having a lower surface connected to the heating system component, an upper surface, and a plurality of extensions extending therefrom,
• a tubular seal plate assembly positioned above the tubular base plate assembly upper surface having a mating surface facing the tubular base plate assembly upper surface with a plurality of grooves therein,
• a sealing material within the grooves,
• a tubular hub assembly positioned above the tubular seal plate assembly,
• a plurality of fasteners to connect the tubular seal plate assembly to the tubular hub assembly, and
• a plurality of external brackets to connect the tubular seal plate assembly to the tubular base plate assembly to secure the tubular seal plate assembly to the heating system component,
• wherein the sealing material forms a first gasket between the tubular seal plate assembly and the tubular base plate assembly, and
• wherein each of the external brackets is joined to one of the plurality of tubular base plate assembly extensions, so that the external brackets and the tubular base plate assembly are integral.
