Baxi has issued a Safety Alert (number 013, Potterton Powermax HE - Flue/Condensate Connector Erosion) in conjunction with Gas Safe.

The alert has been issued in response to a very small risk associated with Potterton Powermax HE boilers manufactured between 2001 and 18 November 2005.

Potterton Powermax HE boilers produced during this time were manufactured with an aluminium flue/condensate connector. Baxi’s continuous improvement programme has highlighted that in very extreme cases, where several factors occur simultaneously, carbon monoxide (CO) above normal operational levels could potentially escape from this flue/condensate connector.

According to Baxi, despite the risk being very small, as a precautionary measure the company has recommended that all original aluminium Potterton Powermax HE flue/condensate connectors be upgraded to black composite plastic versions, irrespective of their condition.

The company will supply and fit the replacement black composite plastic flue/condensate connectors on all affected boilers free of charge.

When undertaking work on Potterton Powermax HE boilers, Gas Safe registered engineers are advised to follow the inspection procedure and further actions outlined in Safety Alert 013. A copy of the Safety Alert can be obtained by calling the Powermax HE helpline on 0800 0288 299 or visiting the Gas Safe website.

A spokesperson for Baxi said: “Safety is of paramount importance to us, so we have taken precautionary action. We know that many of the original aluminium flue/condensate connectors on Powermax HE boilers have already been exchanged during annual servicing and maintenance, but we have issued a Safety Alert and have contacted all known customers that potentially still have a boiler with an aluminium component to offer them a free of charge upgrade. We would like to thank Gas Safe engineers for their anticipated assistance in this matter.”
