This section describes proper HFG2.0 installation. Ensure compliance
with the factory recommendations.
The HFG2.0 installs as part of a gas fuel system as shown in Figure 1-1.
In this arrangement, the HFG2.0 is located downstream from two
normally closed gas shut-off valves.
An alternate arrangement is shown in Figure 1-2. In this installation, the
HFG2.0 is located between two normally closed gas shut-off valves.
For efficient valve operation, filter the fuel through a 40-micron absolute
filter before it reaches the valve. This extends the time between routine
maintenance. Locate the fuel filter as close as possible to the valve
INLET.
