GAS PRESSURE SETTING
The working gas pressure on the water heater is electronically controlled and factory set. Under normal circumstances it does not require adjustment during installation. Perform this procedure only if the unit is not operating correctly and all other possible causes for incorrect operation have been eliminated. Contact Rinnai UK before
attempting to alter the gas pressure. Failure to do so could void the warranty.
1.Turn 'OFF' the gas supply.
2.Turn 'OFF' 230V power supply.
3.Remove the front cover from the appliance.
4.Check gas type switch no.1 of SW2 is in the correct position for the type of gas (Nat. or LPG) you are using. (SW2 is bottom set of switches.)
