The Teddington KBB Remote Fire Valve is an essential safety component for homeowners and professional installers working with oil-fired heating appliances. It provides critical peace of mind by automatically shutting off the fuel supply during fire or overheating events, acting as a failsafe to prevent system damage. While its robust design ensures long-term reliability, users should note that the device requires precise installation of the capillary sensor to ensure accurate temperature monitoring within the system.

No, this is a critical safety device and must be installed by a qualified heating professional to ensure it meets legal safety requirements.
Yes, the Teddington KBB is fully tested for compatibility with modern bio-fuels.
A kink can restrict the flow of the thermal fluid, preventing the valve from activating correctly. If a kink is found, the unit should be replaced.
No, this specific model is factory-set to a 90°C activation temperature for safety standardization.
No, it is a purely mechanical device that operates based on thermal expansion.
It is recommended to have the valve inspected during every annual oil boiler service by a registered engineer.
Once a valve has triggered due to heat, it is designed for safety and cannot be reset; the unit must be replaced by a professional.
Check that the capillary tube is free of sharp kinks and that the sensing bulb is correctly positioned in the heat zone.
Immediately shut off the primary oil supply and contact a heating engineer to inspect the connection points and valve integrity.
Installation should always be carried out by a qualified OFTEC engineer or equivalent professional to meet safety regulations. When installing, ensure the capillary tube is not bent sharply or kinked, as this can restrict the internal fluid movement and lead to valve failure. The sensing bulb must be placed in an area that reflects the true temperature of the appliance without being obscured by insulation or debris. For long-term care, perform a visual inspection of the capillary during annual boiler servicing to ensure no physical damage has occurred. Avoid using harsh chemical cleaners near the valve body, and keep the area around the valve clear of obstructions to allow for easy emergency access.
