Qn & r`nnriifinninn Water Haatinn and Plumhinn System-- CITY_OF SANTA ANA 4914ng and Building Agency ass of thePolgrowdsed. FOR PERMIT ISSUANCE § 110.0-110.3: Certification. Heating, ventilation, and air con itioning equipment, water eaters, an a o California Energy Commission. r regu ate appliances must e certified by the manufacturer to the Master ID: § 110.2(a): HVAC Efficiency. Equipment must meet the applicable efficiency requirements in Tables 110.2-A thr 496tle: Controls for Heat Pumps with Supplementary Heaters. Heat pumps with supplementary heater must have control requirements § 110.2(b): as specified in § 150.0(h)7 and § 150.0(1)2. * Thermostats. All heating or cooling systems not controlled by a central energy management control system (EMCS) must have a § 110.2(c): setback thermostat. * Insulation. Unfired service water heater storage tanks and solar water -heating backup tanks must have adequate insulation, or tank 11 0.3c 3: surface heat loss rating. Isolation Valves. Instantaneous water heaters with an input rating greater than 6.8 kBtu per hour (2 kW) must have isolation valves with § 110.3(c)6: hose bibbs or other fittings on both cold and hot water lines to allow for flushing the water heater when the valves are closed. Backup Heat and Ventilation. Air -source heat pump water heaters must have backup heat (internal or external) if inlet air is §110.3(c)7: unconditioned, unless compressor cut-off temperature is below Heating Winter Median of Extremes from Reference Appendix JA2. Heat pump water heater installation space and/or communicating space(s) must meet minimum volume, ducting, and/or grille net free area by kBtu/h of compressor capacity. Pilot Lights. Continuously burning pilot lights are prohibited for natural gas: fan -type central furnaces; household cooking appliances § 110.5: (except appliances without electrical supply voltage connection with pilot lights that consume less than 150 Btu/h); pool and spa heaters. Building Cooling and Heating Loads. Heating and/or cooling loads are calculated in accordance with the ASHRAE Handbook, § 150.0(h)1: Equipment Volume, Applications Volume, and Fundamentals Volume; the SMACNA Residential Comfort System Installation Standards Manual; or the ACCA Manual J using design conditions specified in § 150.0(h)2. § 150.0(h)3A: Clearances. Air conditioner and heat pump outdoor condensing units must have a clearance of at least five feet from any dryer outlet or vent. Liquid Line Drier. Air conditioners and heat pump systems must be equipped with liquid line filter driers if required, as specified by the § 150.0(h)36: manufacturer's instructions. System Selection. Equipment sizing and selection must meet the cooling and heating loads of § 150.0(h)l & 2, and systems must be § 150.0(h)5: sized per ACCA Manual S-2023 with no minimum cooling capacity. Furnace heating capacity must meet ACCA Manual S. Heat pump heating capacity must meet minimum CBC requirements without including supplementary heat with no limit on maximum heating capacity. 150.0 h 6: Defrost. Installer -adjustable defrost delay timers must be set to greater than or equal to 90 minutes. CF2R certification required. * Supplementary Heating Control Configuration: Heat pumps with supplementary heating must have controls to lock supplementary § 150.0{h)7: heating above outside air temperature no qreater than 35*F, allowed durinq defrost or emergency o eration. CF2R certification required. ' Sizing of Electric Resistance Supplementary Heat: When heat pumps have electric resistance heat, the capacity of electric resistance § 150.0(h)8: heat must not exceed the heat pump nominal cooling capacity (at 95*F ambient conditions) multiplied by 2.7 kW per ton, rounded up to the closest kW. Capacity Variation with Third -party Thermostats: For variable or multi -speed systems, the space conditioning system and thermostat § 150.0(h)9: must be capable of responding to heating and cooling loads by modulating system compressor speed and must meet thermostat requirements of § 150.0(i)2. CF2R certification required. Thermostat. All heating or cooling systems including heat pumps which are not controlled by energy management control system EMCS) must have setback thermostat. Additional requirements for thermostats that control heat pumps with supplemental heating include § 150.0(i): thermostat must display outdoor air temperature, must lock out supplementary heat when outdoor air temperature is above 35*F, and must notify when supplemental heat is in use.* Water Piping, Solar Water -heating System Piping, and Space Conditioning System Line Insulation. All domestic hot water § 150.00)1: piping must be insulated as specified in § 609.12 of the California Plumbing Code. * Insulation Protection. Piping insulation must be protected from damage, including from sunlight, moisture, equipment maintenance, and wind, as required by §120.3(b). Insulation exposed to weather must be water retardant and protected from UV light (no adhesive tapes). § 150.00)2: Insulation covering chilled water piping and refrigerant suction piping located outside the conditioned space must include, or be protected by, a Class I or II vapor retarder. Pie insulation buried below grade must be installed in a waterproof and non -crushable casing or sleeve. Gas or Propane Water Heating Systems. Systems using gas or propane water heaters to serve individual dwelling units must § 150.0(n)1: designate a space at least 2.5' x 2.5' x 7' suitable for the future installation of a heat pump water heater, and meet electrical and plumbing requirements, based on the distance between this designated space and the water heater location; and a condensate drain no more than 2" higher than the base of the water heater Solar Water Heating Systems. Solar water heating systems and collectors must be certified and rated by the Solar Rating and § 150.0(n)2: Certification Corporation (SRCC), the International Association of Plumbing and Mechanical Officials, Research and Testing (IAPMO R&T), or by a listing agency that is approved by the Executive Director. Ducts and Fans §110.8(d)3: Ducts. Insulation installed on an existing space -conditioning duct must comply with § 604.0 of the California Mechanical Code (CMC). If a contractor installs the insulation, the contractor must certify to the customer, in writing, that the insulation meets this requirement. CMC Compliance. All air -distribution system ducts and plenums must meet CMC §§ 601.0-605.0 and ANSI/SMACNA-006-2006 HVAC Duct Construction Standards Metal and Flexible 3rd Edition. Portions of supply- and return -air ducts and plenums must be insulated to R-6.0 or higher. Ducts located entirely in conditioned space as confirmed via field verification and diagnostic testing (RA3.1.4.3.8) do not § 150.0(m)1: require insulation; in dwelling units with attics, the ducts must be below the ceiling separating occupiable space from the attic. Connections of metal ducts and inner core of flexible ducts must be mechanically fastened. Openings must be sealed with mastic, tape, or other duct -closure system that meets applicable UL requirements; or aerosol sealant that meets UL 723. The combination of mastic and either mesh or toe must be used to seal openings reater than ''/.", if mastic or toe is used. Building cavities, air handler support
