Furnace and boiler equipment of low pressure type [operating at pressures of 15 psig (103,000 N/m2) or less for steam equipment, or 160 psig (1,100,000 N/m2) or less for hot water equipment] when installed in accordance with manufacturer recommendations or furnace and boiler equipment of residential type [200,000 Btu/hour (210 MJ/hour) input rating or less] is not required to be enclosed.

2. Furnace rooms protected with automatic sprinkler protection.

3. Boiler/furnace equipment rooms protected in accordance with the Boiler Code.

(Boilers over 200,000 BTU require approval by the Department of Labor and Training.)

602.8.2 Emergency controls shall be provided in all structures classified as a day-care occupancy or residential board and care occupancy in accordance with the following: B

(1) Emergency shutoff switches for furnaces and boilers in basements shall be at the top of the stairs leading to the basement.

(2) Emergency shutoff switches for furnaces and boilers in other enclosed rooms shall be located outside of the room.

602.9 Structural

602.9.1 General: Where buildings are undergoing reconstruction including structural alterations, the provisions of this section shall apply. B

602.9.2 Reduction of strength: Reconstruction shall not reduce the structural strength or stability of the building, structure or any individual member thereof. B

Exception: Such reduction shall be allowed provided that the structural strength and the stability of the building are not reduced to below the Building Code levels.

602.9.3 New structural members: New structural members in reconstructions including connections and anchorage, shall comply with the Building Code unless the authority having jurisdiction specifically allows replacement with like materials. B

602.9.4 Minimum design loads: The minimum design loads for the structure shall be the loads applicable at the time the building was constructed, provided that no overstressed condition is created. B

602.9.5 Structural alterations: Buildings and structures undergoing structural reconstruction shall comply with this section. B

602.9.5.1 Evaluation and analysis: An engineering evaluation and analysis which establishes the structural adequacy of the altered structure shall be prepared by a registered design professional and submitted to the code official where more than thirty (30%) percent, within a 12 month period, of the floor and roof areas of the building or structure have been or are proposed to be involved in structural alteration. The evaluation and analysis shall demonstrate that the building or the buildings' structural system once altered complies with the Building Code for wind loading. The areas to be counted towards the thirty (30%) percent shall be those areas tributary to the vertical load carrying components such as joists, beams, columns, walls and other structural components that have been or will be removed, added or altered, as well as areas such as mezzanines, penthouses, roof structures and infilled courts and shafts. B

Exceptions:

1. Buildings of Group R occupancy with no more than 5 dwelling units or guest rooms used solely for residential purposes altered based on the conventional light-frame construction methods of the Building Code.

2. Where such alterations involve only the lowest story of a building and change of occupancy provisions of Chapter 7 do not apply; only the lateral force resisting components in and below that story need comply with this section.

602.9.6 Additional vertical loads: Where gravity loading is increased on the roof or floor of a building or structure, all structural members affected by such increase in loading shall meet the gravity load requirements of the Building Code. B

Exceptions:

1. Structural elements whose stress is not increased by more than five (5%) percent.

2. Buildings of Group R occupancy with no more than 5 dwelling units or guest rooms used solely for residential purposes altered based on the conventional light frame construction methods of the Building Code.

602.9.7 Voluntary lateral force resisting system alterations: Alterations of existing structural elements that are initiated for the purpose of increasing the lateral force resisting strength or stiffness of an existing structure, and are not required by other sections of this code, shall not be required to be designed for forces conforming to the Building Code provided that an engineering analysis is submitted to show that:

1. The capacity of existing structural elements required to resist forces is not reduced;

2. The lateral loading to existing structural elements is not increased beyond their capacity;

3. New structural elements are detailed and connected to the existing structural elements as required by the Building Code;

4. New or relocated non-structural elements are detailed and connected to existing or new structural elements as required by the Building Code and

5. An imminent danger as defined in this code is not created.

Voluntary alterations to lateral force resisting systems conducted in accordance with the referenced standards of the Building Code shall be permitted. B

NOTE: Where the section is followed by the letter "B", "F", or "O", the following meaning shall apply:

"B" This means that the Building Official or the Plumbing, Mechanical or Electrical Inspector shall review the plans, issue the permit, inspect the installation, and approve the final certificate.

"F" This means that the Fire Official shall review the plans for approval, the Fire Official and/or the Building Official inspects the installation, and the Fire Official observes the final test and approves the final installation. The Building Official shall issue the permits.

"O" This would indicate another State agency approval and inspection is needed. An explanation will indicate the agency and approvals needed.
