What it is

This is a gas valve assembly for Ferroli gas boilers, supplied under Ferroli part number 39810200 and built around the Honeywell VK4105C valve body. It controls the flow of gas to the burner, opening and modulating supply in response to the appliance's demand and safety interlocks. It is listed by Ferroli as the gas valve for the SYS 10-23 and the Commercial Rendimax EL range.

Signs this part needs replacing

  • The burner fails to light and the appliance goes to lockout on a call for heat
  • The flame lights and then drops out shortly after ignition
  • Intermittent lockouts that clear on reset but return
  • Unstable or poorly modulated flame, with the burner unable to hold a steady rate
  • Visible damage, corrosion or gas leakage at the valve body or its connections

Before you order

  • Confirm your appliance model and product code against the fit list above
  • Check the valve body marking reads Honeywell VK4105C before ordering
  • Verify the part number on the existing valve or the manufacturer's parts list for your appliance variant
  • Gas-carrying components must be fitted and commissioned by a Gas Safe registered engineer
