David Meiland Posted January 23, 2011 Report Share Posted January 23, 2011 We recently removed a pair of propane water heaters (one for radiant, one for DHW). They were side by side and wye'd together at the ceiling to a single pipe thru the roof. Combination of B vent and this shiny single-wall aluminum stuff. The long piece of shiny AL went down inside the B vent. Not real impressive. What is the AL pipe actually made for? Quote Link to comment Share on other sites More sharing options...
