Previous models of my stove had a ceramic blanket on top of the baffle, held
in place with a steel disk.

Looks like that design feature has largely gone away on current stove designs.

My draft is too strong for my insert, and I'm wondering if I put the blanket back in, I might slow the air a bit.

What was the function of the blanket, and why'd it go away from common use?
 
From what I heard it actually did nothing. Maybe caught some particulates during the EPA testing process. Caused more user problems than anything.

That was my first instinct, that it was put in to catch and burn some emissions. I'm sure that once it gets hot, it does just that.

I'm just trying to cause a bit of turbulence and decrease airflow, as I don't think a flue damper is an option for me. A little cleaner burn would be a nice byproduct of what I'm trying to accomplish.

I bet they make it a messier job to clean the stove above the baffle.
 
Several stoves still employ this method to improve secondary combustion efficiency.

Think adding one back would do anything to slow the draft a bit? It would certainly be in the way of the current airflow.

I had leftover from my liner install, but it got discarded. If I had it, I'd just try it out for kicks.
 
Maybe slightly, but I wouldn't expect a major change with a 1/2" blanket.

Thanks. Hadn't realized the liner wool was 1/2", and the one intended for the purpose is 1".

$15 online for a 1" thick x 16 x 24 piece of SBI ceramic wool. Might be worth giving it a try for that.

You do know your stuff mellow.

I had done a quick googoo search and stopped at the first one I came to that seemed like I was in the ballpark. Wonder what stove calls for the incher?

Ed - My new (2018) Oslo has the blanket over the one-piece vermiculite baffle. It's 1/2" thick.

Thanks! What's the weight look like? I'm thinking I'd just cut a disk out of some plate steel, maybe 5" diameter?

There is no weight - it just lays on the baffle. It is staying in place - I can just see the front edge of the blanket from the firebox and it has not moved a bit. And when I swept the chimney and had the pipe off I could see the back section - all in place.
 
I think it all depends on what material your baffle is made from, if your stove uses bricks or just a metal plate then the blanket is added for the extra insulation, if your plate is ceramic then that's prob enough insulation within its self. Don't forget that these stoves are tested to meet the epa air requirements to get certified for sale, the testing yields results that don't need anymore tuning.
 
I don't see what the big deal is with the blanket, I would pull the upfront secondary air tube then drop the baffle with the blanket on top with the weight with no issues, then clean the liner and have all the junk fall in firebox for easy cleanup. Now if you beat the crap out of the blanket then yea it gets bunched up and will fight you, that is when you just order a new one.
 
my new drolet ht2000 has a blanket held by disk on top

2018 drolet ht2000
On top of a vermiculite or c-cast baffle? How thick is the blanket? 1" or 1/2"?

Looks like a nice big stove.

Hopefully one day they will come out with the 3000 model. That would be a good one.

The HT2000 should have a c-cast baffle. I think all large Drolet stoves do now.

Right you are. I went to the website and the current manual indicates c-cast. Not just, one, but two baffles for this behemoth.

Man, these are economical stoves. I think I saw $1,200 for it and good online ratings.
