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.
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.
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.
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.
