• Only use this part for the specified Braemar SH25 and WF25 models to ensure proper fit and function.
• Follow all relevant Australian standards and Safe Work guidance when servicing gas appliances.

Before you even unbolt the old fan, take a photo of the wiring connections. It'll save you a headache when it's time to hook up the new one, especially if the schematic isn't clear or missing.
