in THE MAIN WALL
Am planning the installation of a GB14260 for a customer in Wheeling W.V.: Can someone tell me the dimentions of a 4" concentric vent assy.? We want to do some preliminary work ahead of the delivery of the equipment and materials and have a 14" sandstone wall to penetrate.   Also would appreciate suggestions on the best way to retain and connect the existing ASME 50 gallon expansion tank to the piping of a primary secondary arrangement with a Spirovent air elimination devise. Will the SPiro tend to cause the depletion of the air in the X tank?. The 3 story historical house has a 1946 copper 2 pipe reverse return with mostly convectors in place .No replies means I,ve said something wrong,need to change my nickname or you great fellow wetheads who have helped me with your experience in the past have not seen my plea.  . Thanks in advance, John(cool head)from Avella,PA
