Guys, I just did a complete cleaning of my FHG before peak season arrives. My boiler had 430 heating hours on it. I swept the chimney even though it didnt look like it needed it (only got a cup of ash, no creosote at all). I took out the tubulators and brushed the tubes. I brushed and cleaned around the combustion chamber and removed the ash under the tubulators. I pulled some side pannels in the firebox and checked the primary air intake it clean. I cleaned the firebox floor, pulled the cast iron grates and cleaned the ash from the secondary air inlet. The question I have is, what's the easiest way to clean the area under the cast iron? There is a small bolt head above the secondary air inlet and it was painful to clean with a small flat piece of wood. What advice do you Froling owners have for cleaning this area? Old paint brush maybe? Yes, I covered the firebox floor with ash before I fired the boiler. I used all the ash from under the tubulators and spread it on the firebox floor. I typically maintain a 1" solid base of ash on the firebox floor, never scrape it clean. For a while I was scooping out the combustor daily but re-read the maintenance instructions and began leaving a layer of ash in the combustor also.
