What it is

The Ideal tandem gas control valve is a SIT-manufactured gas valve assembly used to regulate gas supply to the burner on a range of Ideal appliances. It operates on a 240V supply and uses a 1/2 inch connection, combining the main gas control and the tandem valve function in a single unit. The valve sits within the combustion and exhaust circuit of the appliance, controlling gas flow and modulation so the burner lights and runs at the correct rate.

Signs this part needs replacing

  • The burner fails to light or lights intermittently despite a call for heat
  • The appliance locks out shortly after ignition or during the run cycle
  • Flame control becomes erratic, with poor modulation or an unstable flame
  • Gas is not held at the valve when the appliance is off
  • Repeated lockouts that clear after a reset but return

Before you order

  • Confirm the appliance model and GC number against the compatibility list, as the same valve body is used across several Ideal variants
  • Check the numbers on the existing valve against the alternative part numbers listed below before ordering
  • Allow for any seals or gaskets disturbed during removal, as these are not supplied with the valve
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
