Issues after new Chimney instal Jotul F45 v2

[VermontCrapstings]

I had a chimney specialist that came highly recommend come out to replace my old clay lined chimney with Duravent class A.

They have had some hiccups and were unable to fully complete the project but said the stove was ready to burn as it was. I have been burned by just about every single company I have hired to do any sort of work for me, not just stove/chimney related work. So, as a habbit of necessity I always go behind them and verify everything has been done properly.

I had requested they install a new key damper as a precaution since I would be unacustomed to the draw on the new chimney. This is what I found on the connection to the stove to the new chimney.

Looks like they used the DVL adapter which is a lousy fit on many modern stoves. Regular DVL without the adapter often is a better fit to the flue collar.

I am just glad I did not light a fire, as I was enthusiastically encouraged to do. What adapter part # would you recommend?

 

[begreen]

No adapter needed. Just replace it with a 6" section of DVL stovepipe.

So no key damper just a straight DVL 6im section?

I had no adapter on mine. My Excel double wall fit right on the collar.

Curious, what was wrong with the clay lined chimney? Why didn't you just put an insulated liner down it? Would have been less expensive.

I got a $15 6" damper and installed it in the 6" straight. Drill 2 holes and it's a done deal.

Get a long drill bit!

Nah, marked 2 spots straight across from each other and drilled each side separately.

i did mine after installing. Front and center location. No space for drill in the back. No need to disassemble the pipe.

The DVL key damper comes only in their adapter. It may not be necessary. How tall is the flue system on the stove?

Easier in single-wall pipe. For double wall stove pipe the damper needs a longer shaft on both sides of the damper plate to account for the additional thickness.

Yes, I'm in DVL. The "universal 6"" i got has plenty of shaft.

Multiple reasons. For one, it was an OLD clay lined chimney, so it was an unusual diameter that would require busting out to line. The exterior chimney was not in the best of shape so it was a toss up if it would survive said busting. In addition to that I had reason to believe the liner may have been compromised. There was some darkening along one section of the chimney that led me to believe there may have been some exhaust gas leaking. Better safe than sorry.

I will have to verify but I believe 22'.

Thanks, that's good to know that . Our local hardware store's damper didn't . It was definitely just for single wall. Do you remember where you got yours or the brand?

That may be ok. It's worth trying without the key damper. This can be added later if need be.

If I get to the hardware store I'll look. It was just a universal, made in USA damper is all I remember.
