Help with pipe install (appliance adapter)

Hi everyone, I recently purchased a Country Flame Harvester and have been getting ready to install it. I picked up a simpson duravent 3" pellet vent kit. I can not get the appliance adapter inserted into the stove. It simply does not fit. The stove calls for 3 or 4" pipe so I did not screw up there. I measured the pipe that exits the stove. It is 3". I also measured the inner opening of that same pipe. It's about 2 3/4" maybe a little more. Is this normal? Should the inner opening be 3" and not the overall diameter? Is it okay to bend the male adapter so that it will fit in the stove? I actually have tried this, this adapter piece is pretty mangled and it STILL won't fit in the stove. Even if it did I don't know that I'd feel safe about connecting them this way. Anyway, any advice would be appreciated. I plan on calling Country Flame and Simpson on Monday. My gut tells me that the stove is fine and that the appliance adapter should be smaller in diameter.

Thanks,
Dave

Anyone?......I take no one has had this problem?

I have the simpson pro kit, stove adapter #3PVP-ADBK and the inner pipe measures 3 inches. Have no stove so not sure what my stove pipe size will be.

The Quad units we install actually go together better without the stove adaptor. We just take the first piece of pipe and jam it onto the collar with some silicone. It is a pretty tight fit and doesn't leak if sealed well. I saw that adaptor on the Simpson catalog and ordered it for a few jobs, the guys brought it back and said it was useless.

Thanks for the replies everyone.

I could have probably fit the duravent over the stove's exhaust pipe (meaning the male adapter goes over the exhaust pipe rather than into it) but I didn't think this would be okay. I may give it a try if it has worked for other people.

The only thing I could find in the manual was a part number for a piece manufactured by metal-fab. I called Country Flame to ask them about it.

I did experiment with putting the cleanout tee and other pieces directly onto the stoves exhaust. There is definitely more give in the duravent and they at least start onto the exhaust but are very tight. I think I may be forcing one of these into place as suggested by jtp10181

I did call country flame and hopefully they will return my call. Thanks again everyone I really appreciate it. I'll keep you posted.

Use high temp sealer, it is mandatory.

I didn't use the adapter on my Accentra... put the cleanout T right on the exaust outlet.
