(1) Heaters. Heat in every dwelling unit shall be provided with heating facilities capable of maintaining a minimum room temperature of 70 degrees Fahrenheit at a point three feet above the floor in all habitable rooms at any time. No unvented or open flame heaters shall be permitted as main heating source. All heating devices or appliances shall be of an approved type. Existing radiant heaters may be used and maintained if there is no evidence of carbon on any of the radiants and there are no broken radiants. Cooking appliances shall not be used for purposes of heating any portion of a dwelling. Every dwelling unit must be equipped with a thermostat, enabling the occupant to control the heat within his or her unit. Thermostats must be installed and maintained in accordance with the mechanical code adopted in section 22-276.

(2) Water heaters. Storage-type water heaters shall be installed so as to maintain that clearance from unprotected or protected combustible materials as specified by the manufacturer's UL-approved installation instructions.

(3) Maintenance. Sufficient clearance shall be maintained to permit cleaning of heating equipment surfaces; replacement of filters, blowers, motors, burners, controls, and vent connections; lubrication of moving parts; and adjustment and cleaning of burners and pilots.

(4) Venting. Fuel combustion heating appliances shall be vented to the atmosphere. Downdraft diverters shall be provided in the vents from gas and oil appliances. Vents and vent fittings shall be a double-wall type B flue. A vent pipe shall be installed so as to avoid sharp turns or other constructional features that would create excessive resistance to the flow of the products of combustion. All vent pipe connections to a masonry chimney or flue shall be made with a slip joint. The thimble shall be cemented into the chimney and shall not extend into the chimney beyond the chimney lining. A reasonably accessible and approved cleanout opening with a tightfitting cover shall be provided below the lowest vent inlet into any unlined masonry chimney or flue, except that no unlined chimney that is a part of and supported by walls, and terminates above any floor (a "shelf" or "bracket" chimney) shall be used to vent any gas appliance. A gas appliance vent pipe may be connected to the vent pipe of another gas appliance through a suitable Y-junction fitting provided the vent size is increased to accommodate the increased volume of flue gases.

(5) Safety devices. Boilers or furnaces shall be equipped with approved safety devices arranged to limit high steam pressures, water temperatures, or temperatures in warm air furnaces. Each gas-fired boiler shall be equipped with a low water cutoff. All water heaters shall be provided with a water pressure and temperature relief valve to minimize the possibility of explosions. All gas-fired space and central heating equipment, water heaters and gas dryers shall have approved safety pilot assemblies.

(6) Installation. Gas-fired water heaters shall not be installed in pits or other places subject to flooding by water seepage, nor shall they be installed in any room used for sleeping. Water heating facilities for dwellings shall provide water at a temperature of at least 120 degrees Fahrenheit and a recovery capacity of at least 20 gallons per hour.

(1) Power. Habitable buildings shall be connected to electrical power. Every dwelling unit shall be provided with an electrical service entrance capacity of at least 70 amperes or lower capacity approved by the city manager that is sufficient for typical loads expected to be required by each outlet and fixture in the dwelling unit. Every dwelling unit shall have a sufficient number of branch circuits to carry full power to appliances served by its fixtures and outlets.

(2) Fixtures. Every habitable room shall contain two separate electrical convenience outlets, except that in each habitable room one electric light fixture may be installed in lieu of one of the required electrical convenience outlets. Every water closet compartment, bathroom, laundry room, furnace room, and public hall shall contain at least one ceiling or wall-type electric light. Each receptacle box shall be a stationary fixture that is an integral part of the electrical wiring of the entire building. Every outlet and fixture shall be installed and maintained in good and safe working condition. Electrically conductive pull-chain switches in any bathroom, shower room, or water closet room are prohibited.

(3) Extension cords. No person shall install, use, or allow to be used any nonstationary electrical outlets, makeshift outlets, tacked extension cording, or makeshift jury-rigged electric wiring. No extension cord from an electrical convenience outlet shall extend or pass from one room into another room. No extension cord shall be located where foot traffic passes directly over it. No electrical extension cord shall be placed across any doorway or through any wall or partition of any dwelling unit or room therein.

(4) Maintenance. No person shall have frayed and exposed wiring, wiring unprotected by proper covering, fixtures in disrepair, or makeshift wiring of fixture repair. (Ord. No. 2006-78, § 1(Exh. A), 1-8-2007)
