ESW pvd25 burn pot question.

[aarmga]

hey guys my name is Alex,

this is my first post and my first question as stated in the title I have been Englander stove works PDV 25. I have been reading quite a bit and you have my stove tuned in pretty well and I like how it works, I can keep my 2500 square foot house around 65 degrees all winter long with it. What I have a question about is the holes on the side of the burn pot and what they are used for. I did a little searching and did not come up with much info on it. now my question is would it work better if those side holes including the smaller ones we're blocked off and all of the combustion air forced to the bottom of the burn pot instead of half of it going through the side. I really like this forum and decided to sign up for a membership because of all the wonderful information on here. Thanks for all the help guys.

Most likely yes and a few on here have made mods to their burn pots with those side holes plugged. Im willing to bet those side holes were put in to pass the emissions test during production. I can see no reason how those holes help my burn

Those holes just inject air into the flame, on low heat settings, some of the air is wasted.

The more air forced up through the pellets will help it burn better.

The two large holes under the burn plate can be blocked off with either steel wire wool or rope gasket, this will force more air up through the pellets, they will also burn faster so you might want to adjust the LBF and LBA settings to compensate, and the only way is to test each setting over time (20 mins min per setting change).

In my experience, blocking those holes tends to eject more ash out of the burn pot when it is running on low. The drawback is that when the stove is on high, the air supply is restricted by the pileup of pellets in the pot and it will burn rich very easily. The holes on the side bypass the burn pot and supply air to the top of the pellet pile, giving you a better burn when the stove is cranked up.

You can play with this by simply putting some steel wool in the holes under the burn plate. Different densities of steel wool can give you varying amounts of air.

Just be prepared to scrape more often if you stove is running on high and you block the holes. You've got to keep the air flowing.

Good luck!

I usually shovel my burn plate off about once every 8 hours. Seems to be happy with that, maybe having more air through the plate will allow longer periods before having to clean the burn plate. I run my stove for a week at a time so the longer the better!
