Mozz, the funnel is clear, I check that fairly often. What's your draft set at? I think at .02 it works really well. Maybe I need a bigger baro to handle the wind???? I do live on the top of a ridge-line, so if the weather man is calling for wind... I usually get a bit more of it When it's warm, the boiler only runs on timer as well...
I just dumped the ash... 8 days!
Come to think of it... over the summer I was experimenting with the anthrastat setting and had the fire go out... but a problem I had over the summer was not enough draft.mikeandgerry wrote:This advice from Matthaus is excellent. The mechanical code for combustion air in the boiler room is quite specific. I had to increase the combustion air in my boiler room by adding about 30 sq inches of free air louvers to the room. It greatly improved the draft. I have never had an issue with transfer head fires at any setting and I have tried the lowest of low settings in experimenting: 120deg on the anthrastat and 1 click on the gear. I have had the fire go out but not creep into the transfer head.Matthaus wrote:I believe fire in the transfer head us from insufficient draft not too much. The air both under and over the fire will exit the top of the fire pot (thus into the coal tube) if there is not enough draft drawing it out the fire tube and through the cyclonic separator area. Also Pret don't forget your issues with boiler room pressure since it is part of the house, funny things might be happening. I would install a tube outside that you can check regularly with the manometer to verify outside pressure Vs boiler room pressure.
It's difficult to suck air out of a bottle and maintain a flow without a hole in the bottle.
