What it is

A genuine Andrews Water Heaters Hi-Flo automatic ignition gas valve, part number Z090. When more gas is needed at the burner, the primary control board signals the valve to open, regulating gas flow through the appliance.

Signs this part needs replacing

  • Appliance fails to ignite despite a call for heat
  • Gas valve fails to open or close correctly
  • Boiler locks out on a gas or ignition fault
  • Unusual gas odour near the valve (isolate the gas supply immediately and call a Gas Safe engineer)

Before you order

  • Match the part number on your existing gas valve before ordering
  • Isolate the gas and electrical supply before removing the old valve
  • Fitting and gas work must be carried out by a Gas Safe registered engineer
