These requirements apply to boilers with rated input of 8,000,000 Btu/h or less that are not packaged boilers and to all packaged boilers. Minimum efficiency requirements for boilers cover all capacities of packaged boilers. Maximum capacity — minimum and maximum ratings as provided for and allowed by the unit's controls.Get Price
