SECTION 4: PLUMBING THE GENERATORS (continued)

All plumbing shall be installed by a licensed plumber and conform with local and national codes.

Refer to the plumbing instructions in the individual installation instructions document 4211-1551 for details regarding plumbing of the individual steamers

in your system.

INSTALL THE PRESSURE RELIEF VALVE

Each steamer must have its own pressure safety valve, 10psi (69 kPa). Connect the input of the pressure relief valve into its port on the

steamer. The valve must be within 6” (150 mm) of the steam tank. Run a 3/4” copper pipe from the valve to an appropriate drain.

Do not connect the valve’s outlet to the generator’s drain line! Do not connect the valve’s outlet to the steam line!
