the current set temperature.
3. Adjust the set temperature to your preference.
4. Turn on the faucet.
WARNING
It is dangerous to operate a Tankless Water Heater
unattended. This may occur accidentally if a sufficient leak
develops in the water system or if a faucet is left open. For
this reason The F2GWH will automatically turn off after
operating for 20 minutes and displays Error “En” on the
Display.
E: Winter Use
Winterization
Freezing of the water heater and its plumbing components
will result in severe damage not covered by warranty. For
this reason it is advisable to follow the recommendations
below if the unit is to be stored in a freezing environment or
for long periods of time. At the start of the winter season or
before traveling to a location where freezing conditions are
likely, the unit must be winterized. The very small amount of
water present in the heat exchanger DOES NOT require the
installation of a bypass kit. Winterization can be accomplished
using one of the two common methods of winterization used
for RV water systems:
●
Compressed Air method: Drain all water from the system
opening one tap at a time and using compressed air to
purge all remaining water.
●
Anti-freeze method: Follow the recommendations of the
Recreational Vehicle manufacturer and fill the system with
a non-toxic anti-freeze. Make sure that the anti-freeze flows
from each tap to complete the process.
Antifreeze Device
If you wish to operate the water heater in potentially freezing
conditions the model F2GWH has a built in thermostat that
will start the burner whenever the temperature of the Heat
Exchanger falls below 38°F and will automatically shut off
when it senses a temperature in excess of 58°F.
IMPORTANT NOTICE
To allow the Antifreeze Device to operate you must have
sufficient LP Gas in the tank and 12VDC power available and
you must leave the unit powered with the ON / OFF switch
in the ON position at all times that freezing may occur. It will
not protect the entire RV’s plumbing system. The RV must be
designed for winter use/freezing conditions.
TROUBLESHOOTING
If a failure were to occur in the F2GWH it will be detected by
the Controller Module and the specific cause will be indicated
by the Error Code on the User Control Panel display.
E0: Water Outlet Temperature Probe failure.
An open circuit or short circuit condition is detected: This could
be due to an internal failure in the Temperature Probe or to a
faulty connection (Wires)
E1: Ignition failure or accidental flame off during ignition.
If the established flame signal is lost while the burner is
operating, the control will respond within 0.8 seconds, the
gas valve is de-energized and a new inter-purge and ignition
routine will begin. If the burner does not light, the control will
de-energize the gas valve and will make one more attempt to
relight the burner. If the burner does not relight after the two
trials the control will go into LOCKOUT and the unit will need
to be turned off before it can operate again. (Turn hot water
faucet OFF and back ON to re-set) This could occur for a
number of reasons.
The most common are:
●
Lack of Gas in the tank
●
Faulty Igniter
●
Faulty Igniter connections
●
Improper distance between the Igniter and the Burner
●
Accumulated dirt or obstruction between
●
Igniter and Burner
●
Low Gas Inlet pressure
E2: Flame sensing interrupted during normal operation.
Buzzer will sound.
Possible causes are the same as indicated by Error E1 if any of
these conditions occur during normal operation. A lock out will
occur also in these conditions.
E3: ECO open before ignition or during normal
operation.
This occurs if the ECO thermostat opens. Under normal
circumstances this is due to the Temperature of the water
at the Outlet exceeds 140˚ F (60°C). The cause must be
identified and removed before restarting the unit.
E4: Water Inlet Temperature Probe probe failure.
An open circuit or short circuit condition is detected: This could
be due to an internal failure in the Temperature Probe or to a
faulty connection (Wires)
E5: Blower motor failure.
No motor signal was detected before ignition or during normal
operation. This could be also caused by a wiring fault in the
motor connections.
E6: Over Temperature.
Outlet Water Temperature has exceeded 140°F (60°C) for 3
sec.
E7: Linear valve failure:
The Controller Module detects an open circuit in the Linear
Valve control circuit before ignition or during normal operation
indicating a faulty Valve.
