Systems using gas or propane water heaters to serve individual dwelling units shall include the following components [150.0(N)]: a. A dedicated 125V, 20A (10 AWG copper branch circuit) electrical receptacle that is within 3 feet from the water heater and accessible to the water heater with no obstructions. There shall be a reserved single pole breaker space in the electrical panel labeled "Future 240V Use". Both ends of the unused conductor shall be labeled with the word "spare" and be electrically isolated. b. A condensate drain that is no more than 2 inches higher than the base of the installed water heater, and allows natural draining without pump assistance. c. Designate a space at least 2.5 ft. by 2.5 ft. wide and 7 ft. tall suitable for the future installation of a heat pump water heater (HPWH). d. If designated space is more than 3 feet from water heater, comply with 150.0(n)B. 2. In addition to the local exhaust fans in the bathrooms and kitchens, an exhaust fan shall be sized to provide ventilation for the whole house. The minimum ventilation rate for the whole -building exhaust fan shall be calculated according to ASHRAE Standard 62.2 Equation 4.1(a). The conditioned floor area and the number of bedrooms in the home (the existing house and the addition) will determine the minimum ventilation rate. One of the local exhaust fans in the bathrooms or kitchens may be used to meet the whole -building ventilation, provided the exhaust fan meets the minimum ventilation rated for both the Local Exhaust and Whole -Building Ventilation requirements. The ducting for the whole building exhaust fan shall be sized according to ASHRAE Standard 62.2 Table 7.1 and this exhaust fan shall operate continuously. Identify fan manufacturer, model and sone rating (1 sone for continuous, may be 3 sone for intermittent) on plans. 3. The whole -building ventilation exhaust fan will operate continuously and is required to be rated for sound at a maximum of 1 sone. This exhaust fan can be controlled by a standard on/off switch but the switch must be labeled to inform the occupant that the exhaust fan is the whole -building ventilation exhaust fan and is intended to operate continuously. No specific wording is mandated, but the wording needs to make clear what the control is for and the importance of operating the system. This may be as simple as "Ventilation Control" or might include wording such as: "Operate when the house is in use" or "Keep on except when gone over 7 days" or "Fan is to be left on to ensure indoor air quality." 4. Access to attic furnace must be within 20 feet of unit and shall have a continuous solid walkway at least 24 inches wide. A switch controlled light is also required. [CIVIC 304.4.1]. 5. Countertops in the kitchen, dining area and similar areas require a receptacle be provided for each counter space wider than 12 inches so that no point is more than 24" from an outlet. [CEC 210.52(C)] Additional outlet required between cooktop and sink to meet spacing requirements. 6. Outlets to be tamper resistant per CEC 406.12. 7. Bathroom outlet(s) shall be on a dedicated 20 amp circuit. 8. A kitchen is defined as any room containing cooking appliances. Each kitchen is required to have an exhaust fan ducted to the outside with a minimum ventilation rate and capture efficiency per Table 150.0-G or Table 160.2-G (multi -family). The range hood over the stove may be used to meet this requirement but the range hood must vent to the outside; recirculating range hoods cannot be used. The ducting for the exhaust fan shall be sized according to ASHRAE Standard 62.2 Table 7.1. This local exhaust fan may operate continuously or intermittently. Installing this local exhaust fan in the kitchen will allow the home occupant to regulate the indoor air quality when needed. 9. Provide the following Electric -Ready requirements: [150.0] A. Heat Pump Space Heater Ready. Systems using gas or propane furnace to serve individual dwelling units shall include the following: 1.
