Benchmark Platinum-Edge [ii]: Installation Manual
SECTION 2 – INSTALLATION
NOTE:
It is the responsibility of the customer to source and purchase the appropriate gas regulator
as described above. However, AERCO offers for sale an appropriate regulator, which may
be ordered at the time of unit purchase or separately. Contact your AERCO sales
representative for more information.
On all Benchmark 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 in Figure
2-7a, below (this recommendation applies to, but is not shown, in Figures 2-7b –2-7d).
