Using It on the Job

1. Before touching anything, isolate the power to the ducted gas heater at the main switchboard and perform lockout/tagout procedures.
2. Locate and access the combustion fan assembly, which is usually found near the heat exchanger or burner section.
3. Carefully disconnect the electrical wiring and any mounting hardware, noting their positions for reinstallation.
4. Remove the old fan and install the new Braemar SY638416 combustion fan, making sure all connections are secure and the fan is oriented correctly.
5. Once installed, restore power and conduct a thorough operational check of the heater, including ignition, flame stability, and flue gas exhaust.

Limitations & Safety Notes

• This fan is only compatible with the specific Braemar TH5 models and serial number ranges listed above.
• Installation of gas appliance components should only be performed by a qualified and licensed gasfitter or HVAC technician.
• Always ensure power is completely isolated and confirmed safe before beginning any work on gas or electrical appliances.
• Incorrect installation or use can lead to dangerous operating conditions, including carbon monoxide leaks or fire hazards.

Tradie Pro Tip

Before you swap this fan out, always check the fan motor capacitor first. A weak or failing capacitor can often mimic a failing motor, and it's a much cheaper fix if that's the real culprit and not the motor itself.
