What it is

The Hamworthy 533903017 is a propane gas valve using the SIT Nova 0.820.054 valve body. It regulates gas supply to the burner on Hamworthy Purwell and Purwell Classic/Lowline permanent pilot floor-standing boilers. The valve sits in the gas train ahead of the burner and is controlled by the appliance's ignition and safety circuit.

Signs this part needs replacing

  • Burner fails to light, or lights and then drops out shortly after
  • No gas reaches the burner even with the pilot established
  • Appliance locks out repeatedly on an ignition attempt
  • Flame height or heat output is unstable and cannot be held steady
  • Corrosion, physical damage or a gas smell around the valve body

Before you order

  • Check your appliance model against the fit list above
  • Confirm the valve currently fitted carries the SIT 0.820.054 reference
  • Confirm the appliance is propane-fuelled, as this valve is the propane variant
  • Gas-carrying components must be fitted and commissioned by a Gas Safe registered engineer
