I bought the stove in 2008 the snorkel was an addition specifically made to move the convection blower to a different location inside the stove shell. My stove didn't come with it. It bolts to the heat exchanger where the convection blower use to and the convection blower bolts to the snorkel. The blower is now lower and further back in the stove shell. And yes that picture you remember was from a Saranac There is a gasket close to that area and gaskets need occasional replacement. I'll take a really good look at that entire area when I shut the stove down later today to give it a pre storm cleaning as I will likely be too busy to do it on my normal stove cleaning day, likely will spend a bit of time that day snow blowing.
