Benchmark Platinum-Edge [ii]: Installation Manual
SECTION 2 – INSTALLATION
NOTE:
It is the customer's responsibility 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 2-8a – 2-8e, below.
