Title 24 · California Energy Code

Manufacturer certification & installation eligibility

Part 6 restricts installation to products certified by the manufacturer or Energy Commission and specifies where to confirm compliance (§110.0–§110.4).

Last reviewed: July 6, 2026

Overview

This part of the California Energy Code explains when manufactured equipment, appliances and building components may be installed: manufacturers must certify that their product meets the applicable Part 6 manufacturing requirements, and installations must comply with the corresponding installation provisions (see §110.0).

Key appliance and equipment rules live in §110.1 (appliances), §110.2 (space‑conditioning equipment) and other §110.x sections (for pools, electrical distribution, demand controls, etc.). Appliances subject to the Appliance Efficiency Regulations must be certified to the Energy Commission per Title 20 (e.g., §1606) before installation, while other devices require a manufacturer declaration under penalty of perjury or Commission certification as described in §110.0–§110.4.

The Code also explains how enforcing agencies and project teams confirm certification (for example, by referring to the Commission’s certified‑appliance database, an approved directory, an acceptance letter or a Commission‑approved label) and notes limited exceptions and field‑verification procedures where applicable.

    A6.207.2.6 Variable air volume control for single zone systems. Effective January 1, 2012, all unitary air conditioning equipment and air-handling units with mechanical cooling capacity at ARI conditions greater than or equal to 110,000 Btu/hr that serve single zones shall be designed for variable supply air volume with their supply fans controlled by two-speed motors, variable speed drives or equipment that has been demonstrated to the Executive Director to use no more energy. The supply fan controls shall modulate down to a minimum of [2] / 3 of the full fan speed or lower at low cooling demand.

    A6.207.3 Service water-heating systems and equipment.

    A6.207.3.1 Certification by manufacturers. Any service water-heating system or equipment may be installed only if the manufacturer has certified that the system or equipment complies with all of the requirements of this subsection for that system or equipment.

    A6.207.3.1.1 Temperature controls for service water-heating systems. Service water-heating systems shall be equipped with automatic temperature controls capable of adjustment from the lowest to the highest acceptable temperature settings for the intended use as listed in Table 2, Chapter 9 of the ASHRAE Handbook, HVAC Applications Volume.

    A6.207.3.2 Efficiency. Equipment shall meet the applicable requirements of the Appliance Efficiency Regulations as required by Section A6.210.1, subject to the following:

    1. If more than one standard is listed in the Appliance Efficiency Regulations, the equipment shall meet all the standards listed; and
    2. If more than one test method is listed in the Appliance Efficiency Regulations, the equipment shall comply with the applicable standard when tested with each test method; and
    3. Where equipment can serve more than one function, such as both heating and cooling or both space heating and water heating, it shall comply with all the requirements applicable to each function; and
    4. Where a requirement is for equipment rated at its “maximum rated capacity” or “minimum rated capacity,” the capacity shall be as provided for and allowed by the controls, during steady-state operation.

    A6.207.3.3 Installation. Any service water-heating system or equipment may be installed only if the system or equipment complies with all of the applicable requirements of this subsection for the system or equipment.

    A6.207.3.3.1 Outlet temperature controls. On systems that have a total capacity greater than 167,000 Btu/hr, outlets that require higher than service water temperatures as listed in the ASHRAE Handbook, Applications Volume, shall have separate remote heaters, heat exchangers or boosters to supply the outlet with the higher temperature.

    A6.207.3.3.2 Temperature controls for public lavatories. The controls shall limit the outlet temperature to 110°F.

Frequently asked questions

Do manufacturers have to certify every product before it can be installed?

Yes. Products within Part 6’s scope can only be installed if the manufacturer has certified compliance with the applicable manufacturing provisions (see §110.0 and §110.1). Appliances covered by the Appliance Efficiency Regulations must be certified to the Energy Commission pursuant to Title 20 (e.g., §1606).

How do I verify a product’s certification status?

Certification is confirmed only by reference to an Energy Commission directory/database, a manufacturer’s application plus the Commission staff acceptance letter, written confirmation from a publisher of a Commission‑approved directory, or a Commission‑approved label on the device, per §110.0(b)(3).

What if efficiency data aren’t in the certified database?

When verified data aren’t available in the approved directories, Part 6 allows following Commission‑approved procedures — including default values or approved field verification/test protocols — as described in §110.1(c).
