Hi,
I've been lurking for a while as I decide on a wood burning insert. I've done a ton of searching and can't quite find the answer to my specific situation.
I knew the chimney in our house had been relined... upon close inspection I identified the liner as a 7"x9.5" rectangular stainless steel line set in some type of cement medium. Our house is a 250yr old stone farm house. The chimney is inside the house and is approx 25-30 ft tall. The fire box is 36"w x 25"h x 15"d. The flue damper is a spring loaded unit at the top of the chimney. I am looking at a Regency I1200 or Dutchwest size insert due to the depth constraints in my fireplace.
So I humbly submit the following question: Is it feasible to use a length of 6" flex pipe between the insert and the bottom of the 7x9 rectangular liner? I know the rectangular liner has a cross-sectional area of approx 63" and the 6" flex pipe's area is approx 28.2"... Will this cause significant draft issues? From what I've read, I could put another 6" liner in the chimney, but that will certainly be difficult with two corrugated liners passing along 25 feet.
Thank you in advance for your help/guidance
Cheers,
Stump
