875—90.15(89) Definitions regarding objects. The following definitions govern classification and status of objects in Iowa. To the extent they do not conflict with the definitions contained in Iowa Code chapter 89, the definitions in this rule are applicable to the rules contained in 875—Chapters 90 through 96.

“Active status” means an object is physically attached to the system and any forms of potential energy. The object may or may not be in operation.

“Exempt status” means an object that is not required to be inspected pursuant to Iowa Code chapter 89.

“Inactive status” means the object is no longer in operation and all forms of potential energy have been disconnected in a manner that creates an air gap.

“Modular boiler” means a steam or hot water heating assembly consisting of a group of individual boilers called modules intended to be installed as a unit with no intervening stop valves. Modules may be under one jacket or individually jacketed. The individual modules shall be limited to a maximum input of 400,000 Btu/hour (117kW) (gas), 3 gph (11.4 L/h) (oil), or 115kW (electric).

“Scrapped status” means the object has been permanently destroyed and is no longer physically at the location.

These rules are intended to implement Iowa Code chapters 17A, 89, 252J, and 272D.
