Limitations & Safety Notes

• This fan kit is only compatible with Bonaire MB5 series ducted gas heaters; it is not a universal part.
• Installation should only be performed by a licensed gas fitter or qualified HVAC technician.
• Always follow manufacturer instructions and Australian standards (e.g., AS/NZS 5601) for gas appliance servicing.
• Ensure the heater's gas and electrical supplies are isolated before commencing any work to prevent injury.

Tradie Pro Tip: When swapping out these fans, always double-check the rotation direction on startup. An incorrectly spinning fan can cause issues with combustion and potentially damage the heat exchanger, leading to more headaches down the track.
