Hose used to connect the propane supply to a domestic water heater shall:

Have a working pressure of not less than 350 psig (2413 kPa)
Not exceed 10 ft. (3 m) in length
Not pass from room to room
Not be permitted

The correct answer is: Not be permitted

The correct choice reflects the essential safety protocols surrounding the use of hoses in propane supply systems. In the context of propane systems, particularly for appliances like domestic water heaters, the use of flexible hoses is heavily regulated due to the potential risks associated with flammable gases. Hoses, when utilized in these applications, can present safety hazards if not properly managed or if unsuitable types are used. Flexible connection hoses can be susceptible to wear, damage, and failures that may lead to leaks, which is particularly dangerous with propane due to its flammability and potential for explosion. Due to these inherent risks, the use of hoses for connecting propane supply lines to domestic water heaters is not permitted. This ensures a safer, more reliable setup that typically mandates rigid piping to prevent incidents. By adhering to this guideline, the intent is to minimize the risk of gas leaks and to enhance overall safety in the installation and operation of propane appliances.
