Just wanted to post a picture of the problem that has occurred again on this stove. This is the second stove to have the issue as the first was replaced under warranty. It's obviously a thermal expansion/stress fracture issue. I'm thinking this time I just may get it welded and be done with it. Worst case I'll have a experience welder scarf a new plate on top and then re-drill holes. I can't complain much because it doesn't affect stove performance, just annoying that it needs done.

Wondering if other Quad owners have experienced this same issue.

I've had other stoves leak secondary air from a similar location and it did affect the fire. Jet's of extra fresh air into the firebox can speed up the burn, especially if the jet blasts into the fuel load and not onto the ceiling as the secondary system should work.

Well the plan is to get an experienced welder here and have him weld things so they are cleaned up. I'll consider scarfing on plate if I have to but I prefer not to because the change in metal thickness that those temperatures can cause stress cracking elsewhere which I want to avoid. I'm guessing I'll spend up to a couple hundred dollars depending on if I can find someone I can barter with.
 
This has been a issue. They started making a reline kit. Part #SRV436-540 and a UK-ACT contact your dealer to get it fixed.
 
Yes those are Quad part #. I don't have a link for that. They put a SS 1/8" cover over the existing tubes.
 
I happened to find a pic of the recliner as installed on a QUadra-Fire 3100i. According to the owner this has been in service for 3 years. The stove has seen moderate use and has not been over-fired

Are you burning the stove too hot? I know you are because the manifold is cracking. I install and service quadrafire for a living and the only way you do that is by over firing the stove. Do you burn with the door cracked? Do you burn a ton of scrap wood? like super dry trim pieces and etc? Damper left wide open the entire time? But quadrafire makes a fix kit for this issue, and all you have to do it drill a few holes and mount this special plate and gasket to the air manifold. Its pretty simple and comes with all the bolts and drill bits you need. All you would need is a drill and socket set. But this is an easy fix you dont need to replace the stove yet.

Also those cracks are pretty small compared to the stoves I've seen, half the people have huge holes melted through and don't even notice haha.

Absolutely wrong. This is an issue with the design of these stoves. That is why they have the repair kit and fix them under warranty. They are not the only tube stove manufacturer that has problems with this. But their problem is the worst.

But their redesigned manifolds while kind of a pita to work on seem to have fixed the problem
 
So the photo was not my stove. I bought a home in 2914 and am restoring a 3100i when I discovered a huge hole blown in the manifold joint. My initial thought was an overview situation. I was pretty annoyed w the seller and the mfg but felt a little better after finding some mention of this in these forums.

I have to ditto @bholler. My more extreme situation may or may not be the result of neglect. I’m not beating myself up too much for not crawling into the firebox to discover this in the 15 min I had b4 buying. Lord knows I will next time... but any doofus should have seen the cracks and then the gaping hole when operating, inspecting and servicing their stove/insert over the years. I’ll try to add my pics and some of the parts/fix for others in a separate post.

BUT the pic above is from a different stove. The owner of the pictured insert heavily used the stove but was - to quote his wife - a “fire-nazi” about service and keeping the burns under control. They noticed the cracks, made the warranty claim, and had the kit professionally installed. From reading these older forums that’s a pretty typical story for the we 3100i ACTs, and for some contemporary 4100/ and 5100s (not sure if precise models but if you dig, several models are discussed in hearth.com.

Crystal clear to me that this is a product/design defect. And probably one that violates an implied warranty of merchantability and/or fitness for intended purpose-which is in some states not waivable esp for consumer products. Probably not a products liability (strict liability tort or negligence) problem if there is no issue with the manifold defect impacting the integrity of the firebox or causing a safety issue. Only impact appears to be performance/efficiency.

I commend QF for engineering a fix and (eventually) making parts available (albeit only through their distribution channel) free/cheap.

My main warranty/defect process criticism is that I had to work darn hard to figure this out, and even harder to get info and parts from QF. This seems a pervasive problem. It’s a quadrafure problem and they should own it in a bit more transparent manner, getting (for example) the fix kits and instructions up on their website and perhaps explaining the problem. It’s lame that I had to rely on you good folks to illuminate their oops. And doubly lame that they will not take a call from a consumer and won’t return an email or text except with a roboresponse directing you to one of their dealers.

I’m no expert on this market, but I can tell you that the warranty process and behavior reflects badly on any OEM of a relatively high end consumer product. Even if this is completely resolved in the newer ACC models, I’d weigh these customer service accounts heavily if buying a new $3500 stove.

Two more... one when discovered and another after some cleanup with wire brush and wheel. Due to the buckling, it’s going to require some grinding or torch work to get the recliner kits installed. Parts were free from qf but the dealer wanted 300 bucks for the install.

I never burned the insert w this hole but have to believe it reaked havoc on the 2ndary burn.

It is very common in this many other industries to have dealers take care of all warranty issues. They want to make sure the issue is fixed correcty. If they just gave consumers the repair kits they would have no way of knowing if it was fixed right. Try getting the parts from a car company or appliance manufacturer to fix a problem covered by warranty.

I am really surprised they gave you the kit. We had to become quad service techs to be able to get the parts.
 
That looks pretty bad. I am wondering if leakage from the start up air ports may be contributing to the problem.
