7 Colo. Code Regs. § 1101-5-1-6
Terms in these regulations shall have the same meaning as those found in Title 4 Article 9 of the Colorado Revised Statutes. In addition, unless the context otherwise requires:
Alteration - Any change in the item described on the original Manufacturers' Data Report that affects the pressure-containing capability of the boiler or pressure vessel. Non-physical changes, such as an increase in the maximum allowable working pressure (internal or external) or design temperature of a boiler or pressure vessel shall be considered an alteration. A reduction in minimum temperature, such that additional mechanical tests are required, shall also be considered an alteration.
Apartment house - A building with multiple family dwelling units, including condominiums and townhouses, where boilers are located in a common area outside of the individual dwelling units, such as a boiler room. The exemption for apartment houses with fewer than six units refers to the number of units, not the number of units served by a boiler. Individual dwelling units are considered residences, such that any boiler located inside an individual dwelling unit is exempt.

Boiler, power - See Boiler, ASME Section I.
Boiler, unfired - A steam or other vapor generating system using heat external from itself, usually from the operation of a processing system or other indirect heat source.
Boiler, water tube - A boiler that has water tubes or coils which contain the heating medium constructed primarily of copper or steel material and include but are not limited to the following general attributes:
* ASME Section IV water tube boiler requires forced circulation to prevent overheating and failure of the tubes or coils and has no definitive waterline.
* ASME Section I water tube boiler may not require forced circulation and may or may not have a definitive waterline.
Btu - British thermal unit.
Certificate inspection - An inspection performed by an authorized State or Special Inspector, the report of which is used as justification for issuing, withholding or revoking the certificate of inspection.
Certificate inspection, initial - The certificate inspection conducted by a State Inspector when a new or relocated boiler is being placed in service.
Certificate of inspection - A certificate of inspection, also known as a certificate of boiler operation, an inspection certificate or an operations certificate, is the certificate issued by the Director authorizing the operation of a boiler until a specific date.
Condemned - A boiler or pressure vessel determined by an Inspector to be so unsafe that further use is prohibited until it is satisfactorily repaired or replaced.
Director - the Director of the Colorado Department of Labor and Employment, Division of Oil and Public Safety or his or her designee.
Existing installation - Any boiler or pressure vessel that has received its initial certificate of inspection.
Forced circulation water heater - A water heater requiring forced circulation to prevent overheating and failure of the tubes or coils and has no definitive waterline.
Grace period - The time when a boiler may legally be operated without a valid certificate of inspection.
Hot water storage tank - A closed vessel connected to a regulated boiler. When heated by steam or any other indirect means, these storage tanks shall comply with ASME construction requirements if any of the following limitations are exceeded:
* Heat input of 200,000 Btu/hr
* Water temperature of 210° F
* Nominal water-containing capacity of 120 gal
Inspector, State - A person who is employed and authorized by the Director to perform certificate inspections.
Inspector, Owner-User - A person who holds a valid National Board Owner-User Commission and has passed the examination prescribed by the National Board or is an API-Certified Inspector under a jurisdictionally-approved Owner-User Inspection Organization.
Inspector, Special - A person employed by an insurance company licensed to sell or provide insurance for boilers or pressure vessels in Colorado who holds a valid commission as inspector issued by the National Board of Boiler and Pressure Vessel Inspectors and is authorized by the Director to inspect boilers insured by his or her employer.
Installer - A person or company responsible for setting up for use any regulated boiler or pressure vessel.
Jacketed steam kettle - A pressure vessel with inner and outer walls that is subject to steam pressure and stress, is used to boil or heat liquids or to cook food, and falls under the scope of ASME Section VIII Appendix 9 (Jacketed Vessels) or Appendix 19 (Electrically Heated or Gas Fired Jacketed Steam Kettles).
