What is the maximum propane supply pressure allowed in a central mechanical room?

The maximum propane supply pressure allowed in a central mechanical room is 15 psig. This standard is established to ensure safe operating conditions within the mechanical room. High pressures can pose significant safety risks, including the potential for leaks or catastrophic failures. The 15 psig limit is designed to balance the need for adequate fuel delivery while minimizing the risk of accidents due to over-pressurization.

Propane systems must operate within strict regulatory frameworks, which help maintain safety against flammable gas hazards. Keeping the pressure at this operational ceiling ensures that all components in the mechanical room, such as regulators, valves, and piping, are not exposed to excessive stress or potential failure points. Understanding this maximum supply pressure is critical for technicians to ensure compliance with safety regulations and best practices in gas handling and distribution.
