Worcester Bosch Burner Assembly Natural Gas 87161026740

The Worcester Bosch 87161026740 is a natural gas burner assembly used in the 35 CDi II RSF range of combi boilers. It sits at the heart of the combustion process, distributing the gas/air mixture across the burner surface so it ignites evenly and burns cleanly. Over time the burner can distort, corrode or block, which shows up in the flame picture and in the flue gas readings.

• The boiler fails to light, or lights with a delayed, uneven or popping ignition.
• The flame picture is unstable, lifting off the burner or showing yellow tipping.
• Combustion analyser readings drift outside the expected range for the appliance.
• Soot deposits, discolouration or heat damage are visible on the burner surface or bars.
• The burner is distorted, cracked or corroded on inspection during a service.

• Confirm the appliance model and GC number against the compatibility list, as the same boiler family can use different burner variants.
• Check the existing burner against part number 87161026740 and the alternative number 1013971 before ordering.
• Consider whether the burner gasket or seal for your appliance also needs replacing at the same time.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
