In accordance with the standards and criteria in the definition of \"boiler\" and the procedures in 9VAC20-60-1420 B or 9VAC20-60-1420 C the director may determine on a case-by-case basis that certain enclosed devices using controlled flame combustion are boilers, even though they do not otherwise meet the definition of boiler after considering the following criteria:\n\n1. The extent to which the unit has provisions for recovering and exporting thermal energy in the form of steam, heated fluids, or heated gases;\n\n2. The extent to which the combustion chamber and energy recovery equipment are of integral design;\n\n3. The efficiency of energy recovery, calculated in terms of the recovered energy compared with the thermal value of the fuel;\n\n4. The extent to which exported energy is utilized;\n\n5. The extent to which the device is in common and customary use as a \"boiler\" functioning primarily to produce steam, heated fluids, or heated gases; and\n\n6. Other factors, as appropriate.\n\nB.
