Newbie seeks help: Central boiler 5036 outdoor wood-burner

[Sunshyne]

I’m using green wood as I just moved in this past April. Collected and split all summer. Have about 10 full cords. The creosote buildup is way way too much then it should be. I don’t know what I’m doing wrong. I have an extra solenoid for the damper to open. The seal is tight there’s no air Or smoke escaping. I scrape it almost every time I put wood in it - which is twice a day. Any and all help would be so appreciated!

How hot are you running it? Water temp?

I wouldn't be surprised if it is normal for your unit, if you are able to maintain the water temp and it seems to be working ok I wouldn't worry about it. The only place to be concerned about buildup is at the base of the chimney pipe, if that is allowed to build up too much it will not draft well and you will have trouble burning.

How do you know? Based on what?

Creosote buildup inside the firebox is normal. The water jacket inside is usually between 155-183F so when the boiler is not running, all the tar, gasses, turpentines etc. from the smoldering wood condense on the inside of the firebox. The greener the wood, the more buildup. Unless the creosote is fusing your draft door shut, it will do nothing but burn off when the boiler fires back up. No need to scrape it.
