What it is

The Worcester Bosch main burner injector set (87161402080) is a gas injector assembly that meters the flow of gas into the main burner. By controlling the velocity at which gas reaches the burner, it keeps the fuel input matched to the appliance's design rating rather than allowing excess fuel through. It is used across a range of Worcester Bosch CDI and SBI appliances.

Signs this part needs replacing

  • Burner flame that is unstable, lifting off the burner or burning yellow rather than blue
  • Sooting or blackening around the burner and heat exchanger
  • The appliance failing to reach or hold its rated heat output
  • Gas rate at the meter reading outside the figure on the data badge
  • Repeated ignition lockouts or rough running that persists after a service

Before you order

  • Check the GC number and the appliance serial plate to confirm this injector set matches your model.
  • Cross-check the alternative and previous numbers 1017281 and ZAGAS053 against the part being removed.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
