Brivis Gas Ducted Heater Pressure Switch 115Pa

This Brivis pressure switch is a critical safety component for your gas ducted heater, keeping things running smoothly and safely. When airflow issues or faulty components trip a switch, it's often this unsung hero letting the control board know there's a problem. Replacing a dodgy one is usually a straightforward job, but it’s vital for system integrity.

Designed for specific Brivis models, this switch monitors the gas flow or combustion fan operation, ensuring safe ignition and preventing dangerous situations. Getting the right part is key to avoiding nuisance lockouts, especially during those cold Australian mornings.

Technical Specifications

What's in the Box

• 1 x Brivis Gas Ducted Heater Pressure Switch, 115Pa (BS80021374)

Using It on the Job

1. Before starting any work, isolate power to the ducted heater at the main switchboard and apply a lockout tag.
2. Access the heater's control compartment, usually requiring panel removal.
3. Carefully disconnect the tubing and electrical connectors from the old pressure switch, noting their positions.
4. Mount the new Brivis 115Pa pressure switch in the exact same location as the old one.
5. Reconnect the tubing and electrical wiring securely. Double-check all connections.
6. Restore power to the heater and test the system for correct operation and ignition sequence.

Limitations & Safety Notes

• Always isolate power before attempting any electrical work.
• Gas appliance work should only be performed by a licensed gas fitter in Australia.
• Verify the activation pressure (115Pa) matches your existing Brivis unit to ensure safe and correct operation.
• Follow all manufacturer's instructions and local Australian safety standards (AS/NZS) when installing or servicing gas appliances.

When swapping out pressure switches, take a quick photo of the tubing and wiring connections before you disconnect anything. It saves a headache when you're putting the new one in, especially if you're working in a tight roof space or cabinet. Also, give the tubing a quick check for cracks or blockages while you're there – a simple split tube can give you the same fault as a bad switch.

Pair With

Pair with a digital manometer for checking system pressures or a new Brivis control board if diagnostics point to a broader issue. You might also consider Brivis ignitors & sensors if they haven't been checked in a while.
