Problem Potential cause Solution
Hot water takes
longer to reach
temperature
1. Cold water mixing into hot water side
2. Higher Elevation
3. Incoming water temperature is
abnormally low incoming water
1. Check all valves, inside and outside, to ensure they are closed, check shower head
valve to make sure it is not partially closed.
2. This is normal due to lesser oxygen levels - Contact Furrion.
3. See "Water Control Valve" for adjustment.
Low hot water
flow at the faucet
Lime scale occurs due to precipitation of
"hard " water.
Decalcify your water heater. See "Cleaning and Maintenance" section.
No hot water at
the tap
Gas supply is turned off or interrupted. Check and/or turn on gas supply.

Defect in the appliance. Refer to error codes list on page 15.
Hot water
temperature too
low.
Gas flow to the appliance is too low (gas
inlet pressure 11in. wc.)
● Consult vehicle documentation to determine if gas supply is capable of providing the
necessary volume of gas for the appliance.
● Contact a service technician to verify a suitable gas installation.
Volume flow of hot water is too high and/
or the temperature of cold water reaching
the appliance is too low.
● Turn down hot water at the tap or in the shower in order to reduce volume flow. Or
mix more cold water in faucet.
● Potentially retrofit a volume flow throttle into the water system. This must be
performed only by a certified service technician.
Too much lime scale in the appliance. Decalcify your water heater. See "Cleaning and Maintenance" section.

Water escaping at
pressure safety
valve.
Water pressure in water system too high.
● Adjust the water pump pressure to a maximum of 65PSI.
● If the water system is connected to a central water supply higher than 65PSI (rural or
urban connection), a water pressure reducer must be used.
● Install a water pressure regulator at the fresh water supply.
Lime or dirt under the pressure relief valve
seat.
● Allow the appliance to cool then slowly operate the relief valve by rotating its valve
handle(knob), Fig.36) to flush the water system and attempt to force dirt or foreign
matter out of the pressure relief valve seat.
● Replace pressure relief valve. This must be performed only by a certified service
technician.
