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.

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.

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
