Just had the local chimney guy out to quote a new stainless steel chimney. This will be through the wall and up the side of the house. The gentleman said that instead of going through the eave he would put 45 pipe and go around it. I thought that cutting in would be the way to go as there will be a chase on the house anyway. I had always been told the less bends the better for any chimney and this site has just reinforced that over time. Has any one heard of going around the house eave before?? :question:
 
If you're building a chase, why wouldn't you just remove the portion of the eave in the way of the chase and go straight on up? Rick
 
That was what I thought. The guy seemed like he knew what was going on but was totally against cutting into the eave. Said it would damage the structural integrity of the house. I'm tempted to do this project on my own. Been nothing but a hassle from the start.
 
My chimney goes around my eve with 2 45's and I can tell you that it will affect your draft as well as your ability to easily clean the pipe. Going strait up would be the preferred method.
 
Is he a chimney guy, or is he a skilled carpenter? Who's going to be building the chase? Going around the eave just doesn't make a lot of sense to me, nor does his comment about the structural integrity of the house. Any good carpenter could do that the right way and give you a chase for a straight-up run of chimney, which will be the best for your stove by far. Maybe get somebody who knows what he's about to build the chase, then get the chimney guy to do what he knows how to do. Rick
 
He's supposed to be a chimney guy. I appriciate the advise. It didn't sound right to me. The chase is going to be built by my friend the experienced liscensed contrator with a friendly discount (hope). Have been trying to juggle township, insurance and chimney guy so much thought I might start my own reality TV series.
 
This is baloney. The first choice for best installation would be to go straight up in the interior of the house. The second choice would be to go up through the overhanging eave, honoring clearances and using a proper top flashing and storm collar.

Download the Simpson Duravent installation manual as a guide. You are correct, straight up will work and look better. Perhaps this guy doesn't do carpentry. Just how is an eave structural? FWIW, I would not let him cut through the eaves. It sounds like he is telling you that he doesn't know how to do it.

Have your friend the contractor do the roof surgery and prep for the chimney chase. I'd also have him to the wall work for the thimble per spec and mount the thimble. Then it should be a straight forward process for the chimney installer.
 
Exactly!!! Have seen this diagram before!! I explained to him what I wanted to do and he wouldn't even think of it. I think I'll try some more numbers in the phone book.
 
BG's point about an interior vertical run is a good one...both my stoves are installed that way. Single wall to the adapter at the ceiling, then Class A to daylight. But some installations just don't lend themselves to that, particularly if there's a second story above that you really don't want to run through for whatever reason. Then an exterior chimney in a nice looking chase is a good solution. Rick
