hi folks. this is my first post but I've been lurking for a couple weeks.
I expect to get some "don't do it" replies, but I have a dilemma I'm hoping someone will have some suggestions for.
I have a vintage Airstream type aluminum trailer (Streamline), and I just bought a used Dickinson Marine Newport solid fuel heater for it. http://www.go2marine.com/product/20010F/dickinson-marine-newport-solid-fuel-heater-00-newsf.html
This little stove uses 3 inch stainless pipe, which is also from Dickinson.
Now the problem. Someone used a wood stove in the trailer many years ago, and there is still a piece of 6 inch single wall pipe sticking through the roof. theres flashing on top and a little rain cap and its watertight, but the hole they made is approx 7.5 inches.
Dickinson sells a handy little deck fitting to go through the roof, but the diameter is only 5 inches, and it will not work with the existing hole. The marine stove industry has plenty of fittings for this, but so far they all seem to be too small.
I am now trying to figure out a sensible way to take the 3" pipe through the 7.5" hole, and keep it watertight and safe.
I've thought about a silicone boot, or a 3" pellet stove thimble, or just running the smaller pipe right up through the larger one and packing the sides with something and hoping for the best... basically drilling 5" hole for a factory recommended install is my absolute last resort.
any ideas??
Also, the trailer is permanently parked, so this will NOT be rolling down the road!!
