2 year old Duraliner Rigid rotting out

[farmwithjunk]

Installed 8" Duraliner Rigid end of 2022 and when cleaning today I noticed the outer later has already rotted out. No real rust and it just seems like it deteriorated. Not real happy after spending several thousand on piping.

There is a few inches above the storm collar exposed and this is where it rotted out.

Do you have a picture taken further back? Sounds like a warranty issue. Is that tar on the storm collar?

Its white silicone that is stained. I'll have to take another picture further back but there really isn't anything else to show. It looks like Duravent poorly designed how the inner stainless section comes out and meets the galvalume. It appears to allow water intrusion and probably caused it to rapidly corrode. I'm using their round termination cap.

I'm utterly disgusted over this. It's the only product that fit the chase for zero clearance so besides getting an 6" stove I'm not sure what the options even are. Warranty doesn't apply to no pro installs so I'm probably out $3,000 in pipe after two years.

How does their warranty not cover dyi installs? They sell to the general public so they would have to warranty the general public.

It's right on their website, includeing all Internet sales. So basically they don't have to warranty anything unless you you paid for it to be installed. I'll contact them tomorrow. Even if they replace all of it that doesn't exactly give me confidence in their product. Two years and it rotted out. Even if it was abuse and neglect I don't see how that could happen.

I would still try the warranty for sure. Send pictures and so on. I would also mention that you posted the pics on hearth.com. Sounds silly, but it is the the biggest forum I know of online and many manufacturers are aware of that I believe. My local stove shop actually had a contributor on this forum for some time.

If they deny you at first, I’d ask to speak with the next person up the chain. I think you may have a shot here at getting this fixed by the company if you stay on it.

As mentioned above, a diy install has nothing in reality to do with the corrosion and they should know that.

I would not argue the actual warranty but instead I would stick to how their product is shitting the bed in 2 yrs time. That’s the main thing and I wouldn’t let them distract you in conversation with what’s technically on the warranty. If you’re a big enough pain in the ass, they may decide it’s better to ship you a replacement.

I'm hoping they cover it, paying for an install would have made no difference. Its rusting out above and below the storm collar. I can certainly spend time commenting on every YouTube and Reddit post during the day if they tell me tough luck.

Updated post you can see original install in November 2022.

That's terrible. Was this galvanized or stainless steel?

It's Duraliner so the inner is 304 stainless with a compressed insulation and I think they call it galvalume outer layer. My concern is if it corroded against the masonry then I lose my zero clearance.

Yes galvalume will do that especially in a masonry chase if it has and coal or wood residue in it.

Is there reason to assume the stainless inner liner is intact and that, while zero clearance may technically be compromised, the liner is safe from a practical sense? I know my question may sound a little cheeky, but just asking bc I know there can be a difference between what is technically true and what is realistically the case.

There is no reason to assume that without scanning the liner. And no way to know where the insulation may be compromised

No residue in the chase. It has a non rigid liner before I installed this. I can't easily inspect in the chase but the rust appears to be mostly above the anchor clamp. Galvalume roofs last decades with no issues even on the cut ends I don't see how this rotted out in two years, really started last year. I believe it was from the inside out so somehow moisture related. None of the silicone was compromised but even without it would get very little precipitation.

Was the clamp supplied with the rest?
(I.e. should it have been an alloy that should work with the rest of the metal? Galvanic couples suck...)

Yep. All Duraliner brand.

Looks like they will warranty the rusted out parts but I'll have to see the extend of the damage. Not very confidence inspiring for this to happen and who knows if/when it becomes dangerous inside the chase. I'm not sure if I should drill a hole in the top plate to inspect via endoscope.
