What it is

The Exhausto Fan RSG 200 is a flue gas extraction fan from Andrews, designed for use in their water heaters and gas boilers. It is identified by part number C945. The fan draws combustion gases through the flue system to maintain safe and efficient appliance operation.

Signs this part needs replacing

  • The fan is noisy or makes grinding, scraping or rattling sounds during operation.
  • The fan fails to start or runs intermittently, causing boiler lockouts.
  • The appliance displays a fan-related fault or fails to ignite.
  • Visible damage, corrosion or overheating marks on the fan housing or impeller.
  • Reduced flue draught leading to poor combustion or repeated shutdowns.

Before you order

  • Check the appliance model and serial number against the fit list above.
  • Confirm the existing fan carries the RSG 200 designation and part number C945.
  • Inspect the fan mounting and electrical connections for compatibility.
  • If unsure, consult a qualified heating engineer before ordering.
