CONNECTING THE FUEL SYSTEM
Gaseous fuel systems should be installed
by a licensed plumber who is experienced
in generator installation and is familiar with
local codes and regulations.
When installing rigid natural gas lines,
always use AGA approved black pipe.
In most applications, a manual shutoff
valve and a primary regulator must be a
part of the installation.
A section of UL or AGA approved flexible
fuel line is required to protect the rigid fuel
line connections against vibration from the
generator.
Installing the flexible fuel line with as few
bends as possible will allow the flexible
section to absorb and mitigate vibration.
Never use a flexible fuel line to avoid an
elbow in a rigid line and never attach
gaseous fuel line supports to any part
of the generator. Doing so defeats the
purpose of the flexible fuel line.
After checking all connections for leaks,
check the static gas pressure at the
secondary regulator to ensure there
is sufficient pressure to operate the
generator. (See Owner’s Manual)
If the static pressure is too low, or is higher
than 14 inches of water column, notify the
local gas supplier.
