What it is
The Honeywell Q309A is a thermocouple supplied at 1800 mm length. A thermocouple sits in the flame path of a gas appliance and generates the small millivolt signal used by the gas valve to prove that a flame is present. This type is a gas-boiler and gas-appliance spare within the thermocouple category.
Before you order
- Confirm the existing thermocouple is marked Q309A or that the Q309A is the listed type for the appliance.
- Check the required thermocouple length against the run from the flame position to the gas valve connection; 1800 mm is the length of this item.
- Check the fixing and connection arrangement at the valve end matches the appliance before fitting.
- Have the appliance make, model and gas type to hand when ordering.
