Hello!

This is the second year I'm burning with my hearthstone heritage 8024. Last year, when the stove was hot enough and I turned on the catalyst, I got a beautiful secondary burn with nice flames dancing over the wood.

This year, about 3-4 minutes after I turn on the cat, the flames die out. There is only red embers and sometimes there is backpuffing.

At first I thought it was because my wood was too wet (about 25%), but today I tried with dry wood (15%) and it still does the same thing.

What could cause this? Could it be a problem with the cat?

Clogged cat clogged screen ontop of the chimney restricted chimney high temps outside reducing draft etc etc etc. We need more info.

Hi Poulet01, I burned about 2 cords max with my Heritage 8024. Last week I decided to have it cleaned so I also removed the top front baffle to have access to the cat. The cat was about 99% clogged with black soot???. Was easy to remove with the vac. but I was surprised to see a so fast clogging ??? Curiously the stove was reacting completly opposite the situation : the wood was burning more rapidly even with the air control shut off. I did the dollar check and the doors are really air tight. Now all the stove is clean and I will have to wait next year to see how it works.

Thanks for the reply!

Was it easy to remove the baffle? I'll check this out soon.

No it's easy, well ....just remove the cutter pin from the front air tube, sad Hearthstone doesn't enlarge the cutter pin hole in the air tube for the cutterpin, would be easier to remove the cutterpin and to put it back . Then from under the top baffle, rise the baffle and pull it toward the front of the stove and pull it down and out of the stove. It should give you enough place to see the cats. If clogged, use the vacum round hair brush to clean gently the cats, you also can use an old paint brush to help to dislodge the ashes on the cats while using the vac. You also can remove the rear baffle and the center air tube ( to remove the center tube, you must again remove the locking cutterpin on the right side of the tube) to get closer to the cats.
