Drolet HT-3000 burning way too hot

[shutt1988]

I installed the HT-3000 last January and noticed that I cannot control the burn very well. I used to have an Englander stove and when I shut the damper fully on that stove, within 10 minutes of cutting the air supply off, it would calm the stove down and I could readjust. I try to set the damper so that the flue temperature is right around 800. Sometimes it stays there for 30 minutes or more and I'll walk away to do something, come back ten minutes later and the flue temperature will be at 1,000, I'll fully shut the damper and it cuts the air down enough that the wood itself isn't burning after a couple minutes, but the secondary burn tubes just keep rolling up to 45 minutes.

The damper plate from the factory has a 1/2" or 3/4" hold drilled into the middle of it so even when the damper is fully closed, the stove can still get plenty of air. I had seen a couple other forums, that people had covered this hole and had gotten better results. I did that last night and it seemed to help. This morning when I fired the stove back up, the same thing happened. Although, it only took about 20 minutes for the flue to come back down to 800 after I fully closed the damper which is an improvement. There were no flames, no glow coming from the actual wood or anywhere in the bottom of the stove. But those secondary tubes were just rolling away.

Any people deal with this?

Had the same issue, sort of, it was on a diy smoker. I used magnets to cover the holes. The magnets allowed me to adjust the amount of air entering the firebox thru the holes or close them completely.

How tall is your chimney? The drolets are easy breathing stoves, with a tall chimney of 20+ feet you will need one, if not multiple key dampers. Have you done a dollar bill test on the door gasket?

Try to decrease the primary air sooner; do it in steps and start sooner. Being ("too") late means that so much wood is offgassing that it will provide enough secondary fuel to keep going and keep increasing the flue temp for a significant time.
