Grant Manual Air Vent Kit 28mm VBS62M

The Grant manual air vent kit is a spare component for Grant oil boilers, listed in the valves, vents and drains section of the Grant oil boiler spares range. It provides a hand-operated point at which trapped air can be released from the appliance and its associated pipework. Air left in a system after draining, refilling or servicing causes noise, uneven heat and restricted circulation, so the vent is used during commissioning and routine maintenance to bring the system back to a settled state.

• Water weeping or dripping from the vent body or around the vent screw
• The vent screw is stiff, seized or its head is rounded, so it can no longer be opened and closed cleanly
• Air cannot be cleared from the system even after repeated venting at the same point
• Boiler noise, kettling or poor circulation that continues after the system has been bled
• Corrosion, scale or staining around the vent seat or the surrounding pipework

• Confirm the part number VBS62M or the alternative number 2160600 against the spares list for your appliance
• Check that the 28mm connection matches the fitting on the boiler or pipework where the vent is being replaced
• Have the boiler model and serial number to hand when ordering, as Grant oil boiler spares vary between ranges
• Inspect the seals and washers around the vent while it is removed, as these are a common source of weeps after refitting
