Heatline Fan Assembly Old Vizo D003200906

The Heatline Old Vizo fan assembly is the draught component fitted to a range of Heatline gas boilers. It draws fresh air into the combustion chamber so the gas can burn correctly, then carries the products of combustion away to the flue. The boiler's safety interlock prevents gas reaching the main burner whenever the fan is not proving operation, so a failed fan stops the appliance from firing.

• The boiler locks out or fails to ignite, with the fan proving sequence not completing.
• Grinding, scraping or rumbling noise from the fan housing when the boiler starts.
• The fan runs intermittently, slows down or stops altogether during a demand for heat.
• The appliance fires briefly and then shuts down as the air pressure switch or fan proving signal drops out.
• Visible damage, stiffness or debris around the impeller when the fan is inspected.

• Confirm the boiler model and GC number against the compatibility list, as several Heatline variants use this fan.
• On a Vizo 24, check the serial number: this fan suits units built before serial No. 1062230470.
• If ordering against older documentation, cross-check the previous number 3003200906 or the alternative number 2170004.
