What it is

The Ideal 174378 is a gas valve used on Ideal Commercial Imax Xtra appliances. It regulates the flow of gas into the burner assembly, opening and modulating supply in step with the boiler's demand signal. The valve sits on the gas train ahead of the burner and is a serviceable component on this commercial range.

Signs this part needs replacing

  • The burner fails to light, or lights only intermittently, despite a call for heat.
  • The flame extinguishes shortly after ignition and the appliance locks out.
  • Ignition fault or flame supervision codes appear repeatedly on the controls.
  • Gas pressure at the burner cannot be set or held within the manufacturer's figures.
  • The valve body shows signs of leakage, corrosion or mechanical damage.

Before you order

  • Confirm the appliance model and, where available, the GC number against the compatibility list before ordering.
  • Check the existing valve against alternative number 1781042 to make sure the correct item is being replaced.
  • Assess whether a gasket or seal kit is needed for the joint being disturbed, and order it with the valve if so.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
