    • Incorrect test point pressure. Check pressure at outlet pressure test point on gas valve – compare with value specified on data label.
    • Incorrect gas supply pressure to heater. Check supply pressure at inlet pressure tapping on gas valve with heater on max and all other gas appliances running. -NG – minimum 1.13 kPa. -Propane – minimum 2.75 kPa. Check gas meter regulator outlet pressure and fitting line size and length.
    • Gas supply turned off at gas meter, heater isolation valve or gas valve on/off switch. Check gas supply – turn on if required.
