No person shall construct, install, reinstall, repair, replace, reset, alter, convert or move in any building, structure or appurtenance thereto, without first obtaining a permit therefor from the Commissioner as follows:
(a) Refrigeration producing systems, cooling systems or air conditioning units or systems where such units are integral parts of such cooling systems; or
(b) Heat producing systems, combustion plants, heating systems and air conditioning units in dwelling houses where such units are integral parts of such heating systems.
Every flue erected after June 27, 1949, and every existing flue to be used with a heat generating device or combustion equipment dissimilar to that previously installed or dissimilar to that for which the flue was previously approved, shall be erected or used only if the design and use thereof has been approved by the Commissioner of Air Pollution Control and the Commissioner except that the approval of the Commissioner of Air Pollution Control shall not be required for dwelling house flues or when gas burning equipment is installed.
(a) No existing flue or gas vent shall be used for any appliance or device not similar in size, character, and type of fuel burned to that previously connected to such flue or gas vent, and no existing flue shall be connected to a newly-constructed fireplace, without the approval of the flue or gas vent for such use or installation by the Commissioner.
(b) All chimneys, smokestacks, flues, smoke pipes, and gas vents shall be maintained in a safe and gas tight condition and the Commissioner may prohibit the use of any appliance or device connected to any chimney, smokestack, flue, smoke pipe or gas vent not so maintained.
(c) Any chimney, smokestack, flue or gas vent which becomes unsafe or dangerous shall be made safe or taken down.
(a) Heating systems shall be designed, installed and operated to maintain inside air temperatures not less than those listed in Table A for the specified areas and rooms in buildings when the outside air temperature is zero degrees Fahrenheit (0°F) and there is a wind velocity of fifteen (15) mph. The tabulated minimum inside air temperatures shall be determined by dry-bulb thermometers not less than three (3) feet from outside walls and at a height above the floor at the breathing line of the typical occupants, i.e. three (3) feet above the floor, where the occupants are normally seated and five (5) feet above the floor where the occupants are not seated. Compliance with the requirements of this chapter and with the recommendations of the ASHRAE “Heating Ventilating Air Conditioning Guide” is prima facie evidence of conformity with accepted engineering practice.

(b) Whenever a building is heated by means of a furnace, boiler or other apparatus under the control of the owner, agent or lessee of such building, such owner, agent or lessee, in the absence of a written or verbal contract or agreement to the contrary, shall be deemed to have contracted, undertaken or bound himself or herself to furnish heat in accordance with the provisions of this section. However, nothing herein contained shall apply to buildings or portions thereof used and occupied by trades, businesses or occupations where high or low temperatures are essential or unavoidable.
(a) All heating devices, appliances, accessories, and controls shall be of a type approved by the Board of Building Standards and Building Appeals. Devices, appliances, accessories, or controls approved by the Underwriters Laboratories, Inc., or the American Gas Association, or tested and approved by other nationally recognized testing laboratory which possesses adequate equipment, experience, and competency in this field, may be approved by the Board without additional tests.
(b) No heating equipment or other equipment which produces or may produce smoke, or toxic, noxious or obnoxious gases, or fly ash or dust, shall be installed except in conformity with the Air Pollution Code and the rules and regulations governing such installations promulgated by the Commissioner of Air Pollution Control. Installations of such equipment, except heating equipment in dwelling houses or serving only one (1) dwelling unit, shall be made only if approved by the Commissioner of Air Pollution Control and shall be subject to his or her approval of the completed installation.
(c) All such installations shall also be subject to the approval of the Commissioner.
Whenever the operation of a system has been the cause of a fire, such system shall not be used or operated until it has been inspected by the Commissioner and such alterations and changes made as are deemed necessary by him or her to permit safe operation of the system, and no alterations or repairs shall be made without a permit issued by the Commissioner.
(a) Whenever a new furnace is installed or an existing furnace is replaced in gravity warm air heating systems, any existing narrow throat register boxes located less than one (1) full story height above the top of the furnace shall be removed and replaced with wide throat register boxes.
(b) In new gravity warm air heating installations narrow throat register boxes shall not be used less than one (1) full story height above the level of the top of the furnace.
(a) Where the installation of pipes or ducts in walls or partitions requires the removal of any firestopping, the space around the pipes or ducts at the points where firestopping was removed shall be tightly filled with mineral wool or other noncombustible insulating material.
(b) Where pipes, ducts, stacks, or fittings pass through a floor construction, all open spaces around them shall be filled with mineral wood, or other incombustible insulating material.
(c) Whenever baseboard or wall registers located at the top of supply or return air ducts are installed in stud framed walls or partitions or in construction having concealed interior spaces, an approved firestop shall be installed approximately three (3) inches above such register or grille. In stud framed construction such firestops shall extend the full width and depth of the stud space.
(a) All heating, ventilating or air conditioning systems installed or altered shall be inspected and subject to approval by the Commissioner while in the process of installation and upon completion of the following stages:
(1) When system has been roughed in and connected;
(2) When the system is completely installed and ready to operate;
(3) In alteration work, all new work shall be inspected.
(b) No work shall be covered up or otherwise concealed before it has been inspected and approved. The Commissioner may require the removal of any covering which has been placed over the work which has not been inspected and approved.
(c) No heating, ventilating or air conditioning system, and no altered system, including systems where furnaces have been replaced, shall be used for heating any building until such use has been authorized by the Commissioner.
(d) The Commissioner may seal, or order the sealing, of any furnace installed in violation of OBBC or this Building Code or found to be a hazard to life or property, and such seal shall not be removed without written authority for such removal given by the Commissioner.
