Frequently Asked Questions

Will this thermocouple fit my boiler or gas fire?

The BES 6336 is a universal 900mm gas thermocouple kit designed to fit many popular appliances and gas valves using the supplied adaptor nuts and fittings. Always check your appliance manual or consult a Gas Safe registered engineer to confirm compatibility before purchase and installation.

Can I install this thermocouple myself?

No. All gas work, including replacing thermocouples, must be carried out by a suitably qualified and registered gas engineer in accordance with local regulations.

What does a thermocouple do on a gas appliance?

The thermocouple monitors the pilot flame. If the flame goes out, the thermocouple cools and signals the gas valve to shut off the gas supply, providing essential flame failure protection.

What does the BES 6336 thermocouple do?

A thermocouple is a safety device that senses the pilot flame on a gas appliance. If the flame goes out, the thermocouple cools down and signals the gas valve to shut off the gas supply, providing flame failure protection.

Is this thermocouple really “universal”?

The BES 6336 is a universal 900mm thermocouple kit supplied with a range of adaptor nuts and fittings. This allows it to fit many popular boilers, gas fires, ovens and heaters. However, no product fits every appliance, so compatibility should always be checked before installation.
