NOTE:
It is the responsibility of the customer to source and purchase the appropriate gas
regulator as described above. However, PVI offers for sale an appropriate regulator, which
may be ordered at the time of unit purchase or separately. Contact your PVI sales
representative for more information.
On all CENTURION models it is strongly recommended that the pressure regulator be installed
a minimum distance of 10 pipe diameters between the pressure regulator and the nearest
downstream
fittings (an elbow or the unit itself), and a minimum of 5 pipe diameters between the
pressure regulator and any
upstream
fitting, such as elbow or shutoff valve, as shown below.

the local gas utility for detailed requirements concerning venting of the supply gas regulator.
2.8.4 Manual Gas Shutoff Valve
A manual shut-off valve must be installed in the gas supply line upstream from the Water
