Update: I'm beyond frustrated with Tesla Energy at this point and not sure if I should even proceed with the install at all. There's tons of miscommunication already from 'design change completed' to 'we can't do it until..'
Please see the latest response from Tesla and advise what can be done. Tesla has no issues installing PW in locations that have gas powered water heater, dryer, etc. BUT you can't have gas pipes in the same location. How does that even make any sense! WTF!!!
We have received clarification on the Powerwall and its classification. The current 2019 CEC does enforce the provisions of part 3 on our Powerwall units. Given that our Powerwall is a Energy Storage System, Pre-Engineered of Matched Components.
The language of the code provides 3 scenarios or qualifiers that are governed by part 3.
Part III of this article applies to ESSs that are:
1. comprised of sealed and non-sealed cells
or
2. batteries or system modules that are comprised of multiple sealed cells
or
3. batteries that are not components within a listed product.
There is no written exception to part 3 for self-contained units as expressed below, and in fact we are not a self-contained unit. Rather, we fall under the category of pre-engineered of matched components as defined below.
_____________________________________
Energy Storage System, Self-Contained
Energy storage systems where the components such as cells, batteries, or modules and any necessary controls, ventilation, illumination, fire suppression, or alarm systems are assembled, installed, and packaged into a singular energy storage container or unit.
- Informational Note: Self-contained systems will generally be manufactured by a single entity, tested and listed to safety standards relevant to the system, and readily connected on site to the electrical system and in the case of multiple systems to each other.
Energy Storage System, Pre-Engineered of Matched Components
Energy storage systems that are not self-contained systems but instead are pre-engineered and field-assembled using separate components supplied as a system by a singular entity that are matched and intended to be assembled as an energy storage system at the system installation site.
- Informational Note: Pre-engineered systems of matched components for field assembly as a system will generally be designed by a single entity and comprised of components that are tested and listed separately or as an assembly.

In summary, the Powerwall cannot be placed in a room if there are gas pipes. Upon further review, gas pipes need to be completely cleared or hidden for Tesla to install inside; not just cut short and capped.
