This Braemar Short Neck Combustion Fan is a direct replacement for specific TH3 and TH4 ducted gas heaters, ensuring your unit keeps burning cleanly and safely. Keeping the combustion air flowing correctly is crucial for efficiency and prevents lockout codes, especially during those frosty Australian winter mornings.

When a combustion fan starts to fail, you'll often hear it grinding, or the heater might short cycle. Getting the right part in fast means less downtime and a warm house for your customers.

• HVAC service technicians replacing worn Braemar combustion fans.
• Maintenance teams for residential properties with Braemar ducted heaters.
• Competent DIY owners maintaining their own Braemar TH3 or TH4 units.

Using It on the Job

1. Isolate Power: Always begin by switching off the main power to the heater at the isolation switch or circuit breaker. Use proper lockout/tagout procedures.
2. Access Fan: Open the heater's service panel and locate the existing combustion fan, typically connected to the flue system.
3. Disconnect & Remove: Carefully disconnect the electrical wiring and any associated hoses. Unscrew or un-rivet the old fan from the flue plate. Note how it was mounted.
4. Install New Fan: Mount the new Braemar SY620510 fan to the flue plate using the appropriate screws or rivets. Ensure a tight, secure fit.
5. Reconnect & Test: Reconnect all electrical wiring and hoses correctly. Restore power and conduct a full operational test, checking for proper ignition and exhaust.
6. Check for Leaks: For gas appliances, it's always good practice to check for any gas leaks around connections using a gas leak detector or approved solution after reassembly, though this specific part is on the air side.

Limitations & Safety Notes

• This fan is specifically for Braemar TH3 and TH4 units within the specified serial number ranges. Double-check compatibility before installation.
• Installation of gas appliance parts should ideally be performed by a licenced gasfitter or qualified HVAC technician.
• Always isolate electrical power to the appliance before commencing any work to prevent electrocution.
• Ensure all connections are secure and proper sealing is maintained around the fan and flue system.
• Follow Australian standards and manufacturer guidance for safe installation and operation of gas heating appliances.

When you're swapping one of these, always give the flue system a quick visual check. Sometimes, a blocked or corroded flue can put extra strain on the fan, leading to premature failure. A quick clean can save a call-back.
