On my quest to get better performance from our stove, I was looking at the chimney cap situation. We have a low pitched ranch roof and a massive stone chimney with two flues. One flue is square (used by the furnace on that end of the house), the second flue is a massive round one and it is this one that I have the liner for the stove installed.
There is a blockoff top and bottom (although I need to come up with a mechanical fastener on the top block off--currently it is stuck down with HT silicon, but it has pulled off center both years, opening up a gap).
More worryingly, the liner exits the block off underneath a large flat slate "cap"--this is a very '60s look. It sits up on some "pillars"--some nice matched stones mortared onto the top of the chimney. This slate only covers the fireplace flue, and currently I have a small conventional S/S chimney cap on the smaller flue.
So two concerns--aesthetic (the two parts don't really go together).
More importantly, I have concerns about function.
From where the liner exits to the underside of the slate is only about 6" so I'm worried that there is not enough clearance under the slate to get the best draw
I'm also worried about spark arresting, all the the installers did was crumple up some S/S mesh and jam it into the end of the liner and called it good.
So to solve all these problems I thought what would work best would be to remove the slate (heavy sumbitch for sure) and install a one piece rectangular cap, cut to fit over both flues. Get it made to the right scale and it would enhance the look of the chimney, plus give the ability to clean from the top.
So I'm looking for ideas, recommendations or experiences getting a custom cap made?
