First off - thank you to this community for already answering a ton of my questions as I got up to speed on burning in a wood stove. I've read countless threads and the amount of awesome info and tips on this forum is staggering.
My story - we live in the metro-Boston (metro-Worcester??) area, and installed a Hearthstone Clydesdale last winter. The insert is hooked up to an exterior chimney, approx 35' tall. The dealer used a 5.5" non-insulated flexible liner, and did not install a block off plate. I'm told it was packed with roxul at the top of the chimney.
Since then I've packed the liner at the top of the smoke chamber with more roxul to help with insulation... a little. I've also fashioned a rudimentary block off plate with sheet metal backed with more roxul. This has helped keep the outside air out of our living room. The 5.5" liner remains, and we have plans to replace it with a proper 6" insulated liner to mate with the 6" opening on the stove.
First off - the stove is awesome. I love the large viewing window, specifically the reason we went with the Clydesdale. The stove puts out a TON of heat when it's rolling, and is more than enough to heat a 2800 sq foot house during shoulder season, and definitely helps with the propane bill in the middle of winter.
With that said, I have two issues with the stove.
1) the stove absolutely CRUSHES through wood. The "doghouse" acts like a laser beam and blows a hole through whatever wood is stacked on the bottom of the stove - the primary intake seems to have too much velocity. I can't get more than 4-5 hours of quality burn from a loaded stove. The wood is all well seasoned (all local hardwood, purchased from the dealer "seasoned" and let it sit for another full year, tested in the high teens for MC). I finally broke down and purchased a manometer, and we're getting between -.16 and -.2 in H2O. Hearthstone calls for -.06 to -.1, so we have roughly double the draft, well over the recommended specs.
2) the stove spills smoke like crazy on re-loads, no matter how long I leave the door cracked before opening wide, no matter how slowly I open it, and no matter how wide the window next to the stove is open when I reload. The installer had to ovalize the liner to pass through the existing damper, so I assume this is creating a choke point. I'm hoping I can rule out stack effect as the window(s) open near the stove should equalize the pressure, right??
So the question is - how can I reduce the draft down to acceptible levels so I'm not burning through wood so quickly, and dumping all that precious heat up my chimney? I've spoken with a few chimney sweeps, as well as Hearthstone directly, and no one has been able to offer any usable advise. Hearthstone doesn't make a damper kit for this stove and no one has been able to figure out how to install one in an accessible place.
And how can I do so in a way that doesn't make the smoke spillage worse?
Will moving to the rigid 6" liner make my spillage problem better (hopefully!!)? Conversely, would it make my draft problem worse??
Looking forward to hearing from the experts. Thanks in advance for reading!
