Hay guys okay I started up my wood boiler yesterday ....central boiler 4030.........woke up this morning and it was boiling any reasons why or what i did wrong? I have a new door seal on the door so the door is sealed right. after turning up the heat to get it to stop steaming I turned down the temp on the boiler and I am thinking I might have had too much wood in it I am going to watch it and see what happenes. however anymore Ideas would be handy thanks
