Short run chimney?

[shadow_smoker]

Hello. I am shopping for a wood stove for a school bus. The school bus has been converted into a cabin of sorts--200 square feet with an 8 ceiling. It's moderately insulated, poorly sealed. I'm considering the England 50-TVL17 for heat.

My question is about the chimney run. Assuming I go with England stove, once it is installed there will be a distance of four feet between the stove and the ceiling. If I add three feet of external chimney above the relatively flat, metal roof, I will have a total of 7 feet of chimney. I would like to keep the chimney height above the roof as low as possible. Will this be adequate for good draw? Will a double wall chimney help?

Thanks

I believe page 9 says 15' min.

Ain't gonna work. From the 17-VL manual:

"We require a minimum chimney height of 15.0 ft. Chimney systems shorter than this
may not create the amount of draft which is required to operate this wood burning unit."

You will never get adequate draft with a seven foot pipe. I have one like that on my outdoor stove and more smoke come out of the door than comes out of the pipe.

Thanks for the spec reference. Any known ways to get around this, to create more draft apart from adding another 8 feet of pipe?
