B: Pressure Relief Valve

A new pressure-relief valve, complying with the standard for
relief valves and automatic shut-o ff devices for hot water
supply systems, ANSI Z21.22/C SA 4.4, must be installed at
the hot water outlet connection of the water heater during
installation. Local codes shall govern the installation of any
relief valve. The relief valve is not attached to the gas water
heater.
NOTICES:
●
The following drawing illustrates a pressure-only relief
valve. If local codes require a combination temperature and
pressure-relief valve, you may need to install an extension
piece to ensure that the valve probe is not directly in the
flow path of the water.
●
A pressure-rellief valve supplied with this water heater
must be installed as shown below.
●
Manual operation of the valve should be performed at least
once a year.
●
If the relief valve on the system discharges periodically, a
problem exists. Turn off the water heater, unplug the unit
and call for service.
●
One end of the relief valve discharge line connects to the
hot water outlet pipe as shown above. The other end of
the pipe should be routed to a suitable drain to eliminate
potential water damage.
C. Water Control Valve Flow
Optimization (optional)
The Water Control Valve of the F2GWH provides good control
of the outlet temperature within a wide range of inlet water
temperatures as are normally encountered in Recreational
Vehicles. The unit is shipped with the Water Control Valve set
at fully open/maximum flow. If desired, the operating flow can
be manually adjusted. It is located on the rear of the water
heater.
CCD-0005833 Rev: 04-14-22
In case of operation with extreme cold inlet water temperatures
(approximately less than 45°(F) the performance of the Water
Control Valve can be optimized by adjusting the flow as shown
in Figure 8 below.
NOTE - This also can be accomplished by adjusting the hot
water flow at the faucet.

D: Operating Procedures

The Model F2GWH can be operated from the User Control
Panel which includes the Power ON/OFF switch.
The model F2GWH can be operated in two different
ways:
1. Operate like a Tank Water Heater. The user turns on the hot
water and add cold water to achieve the desired Hot water
temperature.
2. Select the desired temperature by adjusting temperature
setting up (^) or down (v). The UCP settings are from 95°
(F) to 124° (F). The unit will maintain the set temperature.
NOTE – The recommended and Factory setting is 115°F or
46°C.
For normal operation:
1. Turn on the power. The panel will light and will display the
current temperature at the inlet of the unit.
2. Press a temperature selection arrow (up or down) to see
