Is this acceptable boiler/liner work???

[WreckItDan]

Sparky05, just to clarify, barometric dampers can only reduce draft, to maintain a consistent draft over the fire. They can never increase it.

To the OP, the horizontal run is also going to work against you. Is it at least pitched?

Hopefully Hearthman can chime in with some expert (code) advice.

Yes, it is slightly pitched, about 10 degrees or less.

Hello everyone! Glad I stumbled upon this message board, you all seem extremely knowledgeable. Appreciate any advice you have for me...

So we've been having boiler issues for the past two weeks. We had a damper and a couple of other things replaced, but before the technician (an HVAC/plumbing guy) finished the job he mentioned I needed a new liner for the boiler flue. He put an open flame in front of the flue and it was blowing out instead of being sucked in.
Not a valid draft test method

So we agreed to getting it replaced. The boiler is far from chimney and the flue/liner has a bit of a bend to it, so he told us he had to bust open a wall to properly install the liner.
All of us agree that his installation is NOT proper.

They're almost done with the job and just have to "put back the wall" but the job looks really awful to me. Attached are pictures, should I accept this kind of work? And is this the right kind of liner for this application? They said they would patch up the hole in the liner with cement...this isn't acceptable is it? Appreciate any feedback you have, thanks.

It is a shame this guy wants to cut so many corners. There are too many mistakes for it to turn out right.

Use the site member locator in my sig or go to https://www.myhomecomfort.org/ to find someone with combustion analysis training.

Appreciate the advice, I'm def going to find another contractor to finish the job since I don't think it'll ever come out right with these guys...

I know that draft dampeners reduce draft, not increase it, if you read my post again I said that it controls the draft not increases it.
