BURNER PRESSURE ADJUSTMENT
GAS INLET PRESSURE
IMPORTANT – CHECK the gas supply pressure at the inlet to the water heater with the water heater and all other gas burning appliances in the premises operating (burners alight). The minimum gas supply pressures are:
Natural Gas - 1.13 kPa | Propane - 2.75 kPa |
If this minimum cannot be achieved, it may indicate the meter or the gas line to the water heater is undersized. It is important to ensure that an adequate gas supply pressure is available to the water heater when other gas burning appliances, on the same gas supply, are operating.
