We offer the Inferno Down Fire I, which has a nominal output of up to 118,000 BTU/HR with LP and natural gas and 121,295 BTU/HR with oil. The Inferno Down Fire II, which is slightly larger offers a nominal BTU output of up to 166,985 BTU/HR with LP or natural gas and 163,596 BTU/HR with oil. The Inferno Down Fire Boilers fire vertically downward. This design allows for the fire to lengthen, by avoiding any type of distortion of any kind. It also enables the hottest part of the flame to be in contact with the fire tube to help increase in heat transfer.
