Furrion Tankless Water Heater, Continued
Water Control Valve
The Water Heater is equipped with a water flow
control valve, set from the factory at MAX flow.
The valve will reduce the water flow and capacity
through the water heater to improve water heating
performance. Under extreme conditions, it may be
necessary to adjust the valve accordingly:
Cold water inlet conditions approximately
less than 45°F (7°C)
Higher water inlet pressures >65 PSI.
To operate (Fig. 30):
REDUCE water flow: Rotate knob
clockwise until a solid stop.
INCREASE water flow: Rotate knob
counter clockwise until a solid stop.
High Altitude Use
This appliance can be used at high altitude and has been tested
up to 4500ft. For prolonged use at higher altitudes please contact
support@furrion.com
Antifreeze Function
(for FWH09AFA and FWH09AFA-AM models onlyfor FWH09AFA and FWH09AFA-AM models only)
The water heater can be used in freezing conditions, by
operating a burner sequence program to keep the water
liquid. This function turns ON automatically when water
in the appliance falls below 43°F (6°C), then automatically
shuts OFF when it is warmed.
It will likely be necessary to manually adjust the water con-
trol valve to the "min" setting when using the water heater
in freezing conditions.
If the RV is to be stored, with no use, the water heater
must be winterized appropriately per the instructions
on page 9.
The freeze protection system only protects the water heater
appliance from freezing and will NOT prevent freezing of the
water system in the coach. Ensure the coach is properly
insulated and protected from freezing conditions.
It is normal for the water heater to operate the burner
system at dierent frequencies and duration for this mode.
NOTE: The antifreeze function is inoperable if any
of the following are turned OFF:
