What it is

The Sime Upstream Side Mixer Part (SKU 6274303) is a gas boiler spare that forms one half of the mixer connector between the fan and the heat exchanger. It is listed as one of two parts that make up this connection. It is sold for Sime gas boilers in the gas boiler spares range.

Signs this part needs replacing

  • Visible cracking, splitting or damage to the mixer connector body
  • Leaks or signs of escaping gas or water at the connection to the fan or heat exchanger
  • A loose or poorly seated connection between the fan and the heat exchanger
  • Staining or soot deposits around the mixer joint, which may indicate a poor seal
  • Boiler faults or shutdowns that point to the fan to heat exchanger connection

Before you order

  • Check that your boiler model matches one of the listed fits, paying attention to the full model name, such as DEWY 30/130 HE FS or Planet DEWY 90.
  • Confirm that the part is the upstream side mixer part, as this is one of two parts for the connection, and check whether the second part is also needed.
  • Compare the existing component with the part before ordering, including its position on the fan and heat exchanger.
  • Have the work carried out by a suitably qualified gas engineer, and check the appliance manual for any specific fitting or safety requirements.
