Stove exhaust not flush?

[FLank_Sinatra]

<div class="bbWrapper">I&#039;m getting my stove installed and after they installed the chimney portion I noticed it wasn&#039;t flush inside. I asked the installer and he told me this is normal. I&#039;m already irritated since they are going to need to do a 45 degree elbow to go around a rafter in the ceiling. <br /> <br /> Also, is it normal for the pipe + chimney to only be ~10&#039; long on a pacific energy 1.6? I thought it remember reading it needed to be over 13&#039; for a good draft. He told me they just put it a few feet above the roof line.<br /></div>

<div class="bbWrapper">A 10&#039; total chimney is short. Does the installation follow the 10&#039; 3&#039; 2&#039; rule? Additionally, does it follow the requirements found in your stove&#039;s manual? My assumption is that they knew the stove you were installing and had access to the manual to make certain what they put in was as per required.<br /> <br /> Got a pic of this 45 degree situation? Why are you irritated by this? Was this something they didn&#039;t tell you about with an initial quote and provided an additional cost? Is it of aesthetic concern? Are you worried doing this isn&#039;t legit?<br /> <br /> pen</div>

<div class="bbWrapper">In the first pic the black looking ring about two feet in,, Is that a gap where the two pieces fit together or just a shadow??</div>

It&#039;s not flushly inserted. That&#039;s what I was worried about originally.</div>

<div class="bbWrapper">well I hope you did not write a check yet? They could have cut the joist and boxed it in to keep your straight shot. That&#039;s what we did with mine. Not sure about the gap but it would certainly would concern me unless they could provide substantiated proof it was safe??</div>

As long as it is done right and supported offsets are fine. But that gap doesnt look right what does it look like from out side the pipe.</div>

The solution might be to add another 3 ft and a roof brace.<br /> <br /> Can you post some pics of the roof installation?</div>

 

[FLank_Sinatra]

<div class="bbWrapper">Yeah, I wrote the check yesterday and it already cleared. I was really hoping to get an answer yesterday before the installer came back out.<br /> <br /> So I just did the math off the the reciept for all of the materials. It comes out to 10.4&#039; of length of pipe. 6&quot; collar + 35&quot; black double wall + 6&quot; square support + 48&quot; chimney pipe + 24&quot; chimney pipe. It also says 2 6&quot; elbows, but I only see 1..<br /> <br /> I&#039;ll get on the roof tomorrow to take a look at the chimney and get some pics.<br /> <br /> I&#039;m really concerned now. I even mentioned to the installer and he didn&#039;t seem to understand my concern for having a shorter pipe. I saw him briefly look through the manual for where it says that, as did I, but I couldn&#039;t find it either. I do remember reading it places online though.</div>

<div class="bbWrapper">I see two 45 deg elbows. That&#039;s what makes the offset. Sounds like you have about 12.5 ft from the base of the stove. Not great. Let&#039;s see the roof pictures. They will help.</div>

 

[FLank_Sinatra]

<div class="bbWrapper">Ok, I just saw in the manual where it says that the min height is 15&#039;. I understand the two 45 degree elbows now, I thought that was one piece.</div>

 

[FLank_Sinatra]

<div class="bbWrapper">Here are pictures of the chimney. <br /> I&#039;m about to go to the store and tell them I need another 3&#039; of chimney and that I&#039;m concerned about how that one piece isn&#039;t cleanly inserted into the other.<br /></div>

 

[begreen]

<div class="bbWrapper">Hmmm, I was hoping to see the roof and chimney from a greater distance. Take a tape measure and measure horizontally toward the roof peak to see if this complies with the 10-3-2 rule. Other than that it appears to be a good job.<br /> <br /> <a href="https://www.hearth.com/talk/attachments/10-3-2-rule-jpg.139634/" target="_blank" class="js-lbImage" data-lb-sidebar-href="" data-lb-caption-extra-html=""><img src="https://www.hearth.com/talk/data/attachments/139/139636-7e942ddc4f7a550198c32cfd826be977.jpg" class="bbImage " style="" alt="10-3-2 rule.JPG" title="10-3-2 rule.JPG" width="250" height="122" loading="lazy" /></a></div>

 

[FLank_Sinatra]

<div class="bbWrapper">Ok, so even if the chimney is less than the required 15&#039; if it complies with that on the roof it&#039;s ok?</div>

 

[FLank_Sinatra]

<div class="bbWrapper">Here are the measurements.<br /></div>

<div class="bbWrapper">I would try doing some burning before I added more pipe to your set up. With another section of pipe on the roof it looks like you might have to add braces to it, as well. I always think those flue that stick way up out of the roof look a bit funny. If the stove burns fine as it is then you&#039;d be wasting your money adding more pipe and you will make your chimney more difficult to sweep from the top down. You might not be able to reach the top of the pipe with needing a ladder up on the slanted roof and that&#039;s never a good idea since there is no place to lean it when you just have a pipe sticking up.</div>

I talked to the installers and they said that it will work fine for my set up. He said at most maybe 1 foot, but to only do that if it&#039;s leaking smoke when we try it.</div>

It&#039;s close. May work, the PE is an easy breather. But the stove may spill smoke in milder weather due to weak draft. I&#039;d add at least 18&quot; of pipe. That will keep it under the bracing requirement, though there is nothing wrong with a brace.</div>
