This dosent seem right!

Hey Guys.
This is the first time I have seen a flexible flue on a gas mid efficef furnace. I know I have seen the on gas water heater...Is this OK?
I don't think it is...Help

There were no leaks noted. The flue was not touching the air ducts. It only reached a temp of 100 deg.

Several points:
- the snake layout not ok
- the lack of proper support not ok
- if it's that the skinny stuff used for dryers not ok
- if it is actual 'chimney liner product' then it should be ok in terms of temp and longevity. I don't know that the chimney liner product is approved for open install like that though.
- How does the flex terminate at exterior? Does it stick up and possibly flop around or did they add a piece of rigid?
- What's all that white crap all over the ductwork?
- I'm sure someone is going to mention the standing area and light around the unit requirement.
- is that a yellow extension cord or unsecured romex feeding the furnace?

That look like a flexible connector which is made for gas appliance use (that is a gas appliance), however, as I recall, they are not suitable for use in an attic or outside (hmmmm ... there is that "outside" again, as in 'outside the thermal envelope ... yet those are used in basements and garages ... hmmmmm, might not be allowed 'outside the thermal envelope' above the freeze line).

Also, that flexible connector (it is a "connector" - not a "vent") looks to be too close to - laying against - the duct where it should have at least 6" clearance to combustible material. It is laying against the duct as it is not supported properly.

JP: Depends. If it's Simpson DuraConnect single wall it cannot be installed "outside" or in attic. If it's DuraConnect II double wall it can. Not sure about other manufacturers' products.

There was likely a label on that flexible connector that listed the specs, exclusions and warnings.

Dom: A combustible label no doubt.:)

Looks like either a new guy went nuts with pookie (duct sealer) or is trying to hide some bad work.

You've never heard of the pookie man? :D

That's how you track him.

That is mastic, We use it on all of our ducts here in Charleston. If there not sealed this way we develope condensation due to the high humidity in our attics and crawl spaces.

What do they do in FL?

They use the same white duct mastic here in Florida...

[Mike Gault]

And the more mastic the better... I don't like reading the name on the tape through it...
