What it is

The Potterton 5139779 is a gas valve supplied for Potterton Commercial heating appliances. It controls the flow of gas to the burner in response to demand from the boiler's control system, regulating the burner firing rate. It is listed for use on the Potterton Commercial IHE range.

Signs this part needs replacing

  • The boiler fails to light or locks out repeatedly with no other ignition fault found.
  • Gas pressure at the burner cannot be set or held within the specified range.
  • The burner flame is weak, unstable or extinguishes shortly after ignition.
  • Audible clicking or humming from the valve body without corresponding gas flow.
  • Signs of leakage, contamination or debris around the valve body or its connections.

Before you order

  • Confirm the appliance model and GC details against the boiler data plate before ordering.
  • Check the existing valve body for the part number stamped or labelled on it.
  • Verify that the fault is with the valve itself and not the ignition, detection or control side of the appliance.
  • Gas valve replacement is a gas safety-critical task and must be carried out by a competent Gas Safe registered engineer.
