I just read on somewhere that the duravent pro comes with an oil lubricant on it. My piping is the same way but I don't get any type of smell. You also shouldn't have to RTV your connections because of the gaskets on the inside. However, I guess it doesnt hurt. I used a metallic tape on all of my interior joints. I'll poke around to see if I can see where I read about the oil that's used. Its escaping me right now.
 
It is a lubricant for the O rings on the pipe. I found it in the first couple of pages of the installation manual. Page 4 to be exact.
 
I have silicone rubber gaskets on my pipe the lubricant used was water.

The fact that a smell is there (after more than enough burn in time to remove any normal residual oils that would be on the outside of the venting, etc ...) tells me that things still are leaking the wood smell has just been replaced by the lubricant smell (when this dissipates I hope there won't be a wood smell).

Call the vent maker tell them about it, maybe you can salvage what you have for pipe. At the very least they should replace the venting.

I know this is asking a lot but I'd like to see a picture looking towards where the vent joins the adapter so we can see things at the stove outlet end.
 
The stuff on mine is certainly not water. Maybe water based, but after having put almost a ton of pellets through the stove so far the lubricant is still there. This would tell me its not water based because it would most likely have turned to steam and disappeared.
 
I pulled the exhaust blower off last night and everything looks good. The stove adapter has the same brown/red residue on it as the first picture I posted. I will start the stove again in a little bit to see if anything has changed.
 
Burned the stove for about two more hours, still getting the smell. I have contacted duravent about the problem and linked them to this thread. Hopefully they help me get this fixed soon.
 
Manufacturer says the smell is normal and just the oil burning off. I sent a response back asking about the normal amount of time the curing should take.

Thats an impressive response time Thumbs up to them but this is the first time im hearing of that but im a noob :)

Got another response from Duravent. If the oil is pooling in one spot, like it is on the connections for my horizontal pipes, using some degreaser to wipe it off is ok.

Guess I will just let this thing burn all day day tomorrow and hope that finishes the curing.
 
Rex - I hope the long burn fixes it. I'm gonna check for anything obvious on mine, but will hold off tearing the vent pipe apart until you report back.

I'm still wondering if it's the oil burning off, how are the fumes getting out? I think both of us used 3M tape on the joints (for me it's just 2 joints inside the house).

damn, thats strange, i'll try to remember to forward this thread to a friend who works at duravent see if i can get a comment. i cant imagine the stove dumping enough heat into the pipe to cause this. interesting.

what you are seeing is the oil simpson coats the inside of the stainless with during shipping and or manufacturing. The plastic smell you are smelling is actually a an acrylic sealant simpson uses inside the venting to "melt" into the voids or seems from within the venting. Problem is some of that pipe is so banged up and often too mass produced and there is usually at least one fitting in every install I do that leaking like a bastard. I'm seriously thinking of moving to ICC for new installs if this crap continues....are you reading this Simpson?

Ok,

I think you now have the true story.

If you are smelling it you have a leak.

Now go after warranty replacement until you have no more leaks.

I don't think it is the acrylic sealant that I am smelling. When I took the pipes apart I wiped some of the pooling oil off with my finger and smelled it, that is the smell I am getting. The smell is mostly gone, I don't smell it throughout the house anymore, only behind the stove now.

Hopefully by the end of the day the smell will be gone.
 
Rex - How are you making out? I've run my stove on hi/off thermostat mode for about 5 days with the Pellet Pro Plus vent pipes. I can still smell a bit of the "plastic" smell, but it's much better then the first few of hours of burning where we had to have the widows open.

I am in the exact same spot as you are right now. I can really only smell it if put my head behind the stove. It still bothers me enough that the smell is still there that I won't run the stove while we are sleeping.
 
I guess I don't have this figured out yet. Maybe this isn't the pipe afterall?

I had been running with the rear panel removed since the smell started. I put the panel back on and the smell has come back, it is coming up from between the panel and the stove about where the auger motors are.
 
Has the smell since dissipated?

For the most part the smell is gone. I can still smell it a little bit when I smell behind the stove. I know everyone says it should be cured by now and shouldn't smell, but I am pretty sure what smell is left is from the RTV. I used ultra copper, maybe since it has such a high temperature rating that has something to do with it.

CO detectors never moved from 0 and no one in the house felt sick or anything so at this point I am not overly worried about. I am thinking about putting a new stove in and moving this one to the garage or basement so I guess if i do that it will help me figure out if it the stove, RTV, or pipe.
 
It is wrong from the standpoint it isn't anywhere near as odorless as the mixtures produced for the purposes of sealing flues inside a house, it is fine inside the engine cavity of a car or truck or outside where there is tons of air flow.

Temperature wise it is fine.

Even better are the 600 and 800 degree versions.
