DVL Stove Adapter to NC30 collar

I'm on the final stretch of a NC30 install and had a question on this part.

I ordered a Stove adapter to go on the 30 before the DVL pipe starts but it is not sitting tight in the top of the stove. The crimped end needs to fit snug in the collar of the stove and it is not. Do I just need to force it a bit more than I am?

the NC30 has 3 screw holes on the collar, the DVL blocks these. Should I just get some longer screws and go through the outside pipe into the crimped collar? Should I place some high temp silicone here as well?

Thanks so much for any help.

Are you trying to install the DVL in the collar right off the stove? I snugged my pipe in and tapped it tight with a mallet and block of wood. I used an adapter to go into the horizontal run going through the wall. Being new at owning a 30, i wouldn't want to use double wall right off the stove. But that is just my setup.

I had to grind some of the weld out (inside collar). As have others who used DVL.

I think member greythorn3 had a thread last season about this. We both installed our 30's about the same time.

I have to grind the collar and he next problem I had was with the Close Clearance adapter (DVL-Thimble-Class A). That little connector is a PITA.

Sometimes a little trimming is needed.Just measure out the holes in the flue collar, transfer those measurements to the adapter, then pre-drill through the outer wall and secure with SS screws. You might need to tap it down a bit to get it snug.

I ended up using furnace cement to seal my adapter. I also bought an adapter with a Flue Damper (installed). And the fitment was much better than the standard DVL adapter.

I did manage to get 3 screws in mine, I can take a pic this evening and show you how large my gap is.

Here is the thread from Greythorn3 I mentioned above.

I don't mind the gap at the top of my stove - never even thought about it until I read this thread. Mine is Duravent and I don't have any scews at the stove - just up top. Mine sets in very snug and gravity is my friend. I think putting screws at the bottom is overkill but others may feel differently.
