Harman XXV

Hello, I have a new Harman XXV which is a fantastic stove. It sits in a room 20x20 and is heating my entire single level ranch. However the white woodwork in the room has what looks like a black soot on it when we clean it. I have been vacuuming with a shop vac with a hepa filter. I recently purchased an ash vac which I will now be using. Do you think the soot could have been from vacuuming with the shop vac or could it be another issue with the out put on the stove?

Thx Steve

Since its a new stove I am going to bet its your shop vac. You need a drywall filter or filter bag on it, not HEPA. If you bought a designated "Ash Vac" then you should be all set from now on.

Do you smell smoke while its running? If so you may have an exhaust leak. If not, I am putting my money on ash making it through the shopvac filter during your cleanings.

Shop vac with filter and drywall bag works great.

Really appreciate your feedback. We have no smell at all, I am waiting today for the arrival of the ash vac today and i will update in a week or 2. Thank you

Thanks for the feedback. I am getting the ash vac delivered today and I will update with the results. Thanks again, Steve

When you clean your stove, turn the feed rate dial to TEST to turn the exhaust blower on. All the ash and soot you stir up will be exhausted instead of finding it's way into the house.

Container bag AND HEPA filter

I recommend the LBT.

You need a drywall filter bag, but the HEPA is just as important. Both in tandem will leave ZERO particulates in the air.

If you use just a filter, your gonna have bad results. Just a bag, bad results. You need a quality filter (HEPA) and a Good Fine filtration bag.

I agree. I have used both the drywall bag and HEPA filter this year and have had zero problems. And I burned GS, which provides plenty of ash to test the setup with.
