This Braemar overtemp switch is a crucial safety component for residential gas heating systems, helping to prevent damage and ensure safe operation.
Designed to trip at 130 degrees Celsius, it's a manual reset type, specifically for flame roll-out conditions. Overheat switches are a common call-out, especially on older units, so having a reliable replacement on hand saves a lot of time on the job.
Best For
- Residential Braemar ducted gas heaters.
- Service and maintenance technicians working on gas heating systems.
- HVAC apprentices learning gas appliance safety circuits.
Compatibility
This component is designed as a direct replacement for Braemar gas heaters that use the GH-266 part number, primarily for flame roll-out protection. If you're running a different model, check fittings and specs before ordering.
Features
- Braemar OEM replacement part.
- 130 °C trip temperature for reliable overheat protection.
- Manual reset function, ensuring the cause of the overheat is investigated before restart.
- Specifically designed to detect flame roll-out events.
- Identified as Seeley PN: GH-266, cross-compatible with Braemar systems.
What's in the Box
- 1 x Braemar Overtemp Switch 130 Deg Manual Flame Roll Out (PN: GH-266)
Using It on the Job
- Always isolate power to the gas heating unit at the main switchboard and perform lockout/tagout procedures before commencing any work.
- Carefully disconnect the wiring from the existing overtemp switch, noting the correct orientation if necessary.
- Mount the new Braemar overtemp switch securely in the correct location within the heater assembly.
- Reconnect the wiring, ensuring terminals are clean and connections are tight. Double-check all wiring against the heater's schematic.
- Restore power and test the heater's operation. If the switch trips, investigate the underlying cause (e.g., blocked flue, combustion issues, faulty fan).
- Remember, this is a manual reset switch. If it trips, you'll need to press the reset button after addressing the fault.
Limitations & Safety Notes
- Work on gas appliances requires appropriate licensing, such as a licensed gasfitter and potentially a licensed electrician for electrical work. Always check local regulations.
- Always isolate power before handling electrical components.
- Ensure the cause of any flame roll-out or overtemperature condition is fully investigated and rectified, not just the switch reset.
- Only for the compatible Braemar systems listed above.
When an overtemp switch trips, don't just reset it. That switch is telling you there's a problem. Check for blocked flues, combustion air issues, or a failing fan motor. It'll save you a call-back.
