Can this cap be used for an oil furnace of 84,000 BTUH capacity with existing double wall (6" inner and 9" outer) flue pipe on the roof? Also, are there a storm collar and roof flashing available for the 9" flue pipe?

Our Answer:

That cap is not the correct alloy for oil furnaces. Due to the highly corrosive nature of the combustion fumes from rich organic materials like oil, you will need 316 alloy stainless steel such as the HomeSaver Guardian 9" Diameter 316 Alloy Stainless Steel Chimney Cap. For a storm collar and flashing, you would purchase to match your existing piping.
