Burns hotter. Cleans easier. Lasts longer. Master's CleanFire uses a dry fire chamber to provide hotter, more efficient heat that requires minimal effort to maintain. No ceramics. No damaging corrosion. No creosote build-up. The primary boiler is a true low pressure ASME H stamped boiler. It keeps oxygen out of the system, preventing corrosion to the water vessel. ASME certification ensures the use of the highest quality materials and workmanship resulting in a boiler life expectancy of 40 or 50 years. All of it is run by the exclusive WoodMaster control board, which burns at the optimum rate to meet the heat load. No batch burning or quick cycling. The board uses more than 300 settings to maintain this furnace modulation, increasing efficiency.
