I just built a new ranch home in 2021 and had a masonry chimney installed for my wood furnace. Chimney is located internally in home and is 27 ft from thimble to outlet at the top and is lined with 8x12 clay liner. I just purchased a new Drolet Heat Commander, still waiting for it to arrive. I tried hooking up my old wood furnace (energy king 480) from the old house while waiting for the new one to show up and get a draft reading on the chimney. It seems like this thing is going to draft waay to much, especially for the new Heat Commander since you can't choke down the air on the 2020 ones. I get readings of 0.03 before lighting, once warmed up and burning it reads 0.15, and i can choke down with key damper to about 0.06-0.08.
My questions:
-Can i use key damper on the new one? -Manufacturer specifically states not to
-Should i use the barometric damper? Much debate on creosote buildup with this route
-I'm fearful the chimney liner that was installed is too big. Will installing a 6" liner reduce the draft? Most of the time I think of bigger chimney having low draft concerns...that is definitely not the case with mine. I hate to install a liner in a brand new chimney, but am willing if this is the best option and will help moderate the draft.
-Are there ways to cut air back on the new ones to keep them from "running away"
