Did anyone ever end up installing Dynamat on their rear panels? Thinking about doing the same, but don't want to waste my time if there is no improvement. thx
P43...anyone else ?

I highly doubt Dynamat would have any affect in that application. Thin Roxul batting would be much more effective. If your stove happens to be a corner install, you can get VERY good results with the 3" stuff without removing any panels. Just don't over handle it or you'll be blowing particles out of the convection ports for a while.

I love the sound of the Pellets dropping into the auger. I know my pellet stove is pushing another handful of "logs" on the fire.
It pleases me.

Thank you Rayttt! My thoughts exactly! I love the sounds of my pellet stove, sounds like a cash register saving me big bucks over burning oil! My P43 is right next to my tv and about 6 feet from where I sit. I have no problems hearing the tv from where I sit. Don't get me wrong, I love quiet, my wife likes background noise all of the time, tv etc.... but not me. I like it quiet, but as Rayttt stated, the sound of my P43 is pleasing to me. You'll get used to it soon.
p38x2, I do have a corner install with my P43. Are you saying to just install the batting against the wall? or inside the rear panels? I don't mind the sound of the stove running, but its in our living room, and we end up turning up the TV pretty loud at night to compensate for the hum..

A corner install will always cause the stove, or anything that makes noise, to have more apparent loudness. Exactly the same thing happens when you put a loudspeaker in the corner of a room. My stove without the Roxul is fairly loud, though not obnoxious, but what ends up happening is, like you, I end up turning the TV way up and then the whole place is just plain loud. Tile/hardwood floors exacerbate the issue.
I had a bunch(waay too much) of 3" Roxul left over from some acoustic panels I made for my man cave. I figured if it worked down there, it'll work with the stove.
As long as you don't expect miracles, you'll definitely notice a difference. All I did was take 3, approx 12"x15" pieces, and place them behind the stove. 2 of them are on each side on the floor, on edge, behind the stove so their ends are touching in the corner. The 3rd is simply stuffed directly behind the hopper down to about the level of the bottom panel. Try and keep this piece as flat as possible. You want to keep as much of the Roxul exposed to the noise as possible. There is still PLENTY of airflow back there, so that's NOT an issue. Keep in mind, you'll prob get some particles blowing around for a couple days, but as long as you don't keep touching it, it'll stop..plus it's not irritating like fiberglass is. I have a glass top table very close to my stove and it requires dusting no more than any other flat surface in my house. I have 2 large decorative vases on either side sorta covering the view of the Roxul, though without them, its not that noticeable.
Once it's in place, you'll notice your stove is much quieter, particularly your distribution blower noise. Most of the noise from that will only be coming from the ports, rather than the blower fan itself. Keep in mind, it's not a mute button for your stove, but it does help a very good amount in making your stove noise disappear into the background.
X2, that is why my stoves are in the basement so they can be felt but not heard! LOL

Never really notice the tinkling or crunching of the pellets unless I listen for it. Actually, I think the pellets dropping sounds relaxing like one of those rain sticks. This stove doesn't crunch any more than my 38, but it does give off a really loud pop every couple hours or so. I can clearly hear it upstairs. That should be a very easy mod/fix next time the stove needs a cleaning

awesome, thanks for the advice.. do you have any pictures of your setup?

I know this is an old thread but i figured i would revisit anyways.
So i never ended up adding the Roxul as i was nervous about the fibers blowing around the house. I was thinking of paining them to cut down on the fibers, but i think that would have reduced the sound deadening of the product. Also i have asthma, so i don't really need any other contaminants in the air.
What i did end up doing was buying and installing some 50mil Dynamat (actually the cheaper GTmat version from amazon). Those panels do not get much heat so it should be fine. I cut and installed pieces on the inside of the rear and rear-side panels, and it made it so much quieter. You can still hear the fans, and the auger, but everything sounds more solid sound now. I also realized that the combustion motor was the main source of noise (worn bearings?) so i swapped that out too. $110 later no more cranking the volume on the TV to overcome the pellet stove noise!

I lined the panels with that sound deadening liquid stuff and added a rubber material that they line the inside of military tanks with. I also changed out the motor while it was still under warranty. It's pretty dang quiet now. I'd like it to be completely quiet but that will never happen. I also made a filter for the heat blower motor which works very well. I recently added an arm thing with a rubber stop so the hopper lid doesn't hyper extend.
