The 20248909 Pressure Safeguard Air Kit is built to the original manufacturer’s specifications for sensitivity, reliability, and long-term durability under repeated thermal cycling and varying environmental conditions.
The 20248909 Pressure Safeguard Air Kit is built to the original manufacturer’s specifications for sensitivity, reliability, and long-term durability under repeated thermal cycling and varying environmental conditions. Pressure safeguard assemblies are pivotal in ensuring that the boiler only fires when the combustion environment is safe; inadequate airflow can lead to incomplete combustion, increased carbon monoxide risk, or heat exchanger stress. By precisely detecting whether the fan is achieving the correct pressure differential and flow, this kit helps maintain safe combustion, reduces nuisance shutdowns, and supports compliance with safety regulations.
Over time, pressure safeguard components like diaphragms, tubes, or sensors can degrade due to thermal stress, dust ingress, moisture, or mechanical fatigue, which may result in false signals, boiler lockouts, or failure to start. Symptoms of a failing kit often include recurring fault codes related to air pressure or flow, intermittent ignition attempts, or unexpected shutdowns when internal safety thresholds are not met. Replacing a worn or malfunctioning pressure safeguard air kit with this OEM unit restores accurate airflow monitoring, enhances combustion safety, and improves overall system reliability. Because this assembly interfaces with critical safety controls, installation should always be carried out by a Gas Safe registered engineer to ensure correct placement, secure connections, and compliance with all safety standards.

Standard delivery for all orders over £150 ex-VAT are free of charge.
If we can speed this up, we will, but you can also select Express Delivery when you check out and get your purchase more quickly (usually the next working day, subject to a 1pm cut-off): there is an extra charge for this ranging from £5 to £29.99 depending on the products you are buying.
We partner with several of the best UK carriers (such as TNT, Royal Mail, DPD etc) depending on the type of product and the warehouse it is coming from, and also with some pallet companies for larger items. All of these operate during normal Monday – Friday working hours, and we expect all deliveries to arrive in 5 days. For more details checkout this page.
For all Gledhill Cylinders, a flat delivery charge of £27.50 (ex-VAT) applies, regardless of order value or delivery method. This will be added automatically at checkout.
Having to return a product because it doesn’t fit, or is not what you wanted, is really annoying! To try and make sure this isn’t necessary we have lots of helpful advice on our site, and you should feel free to call our experts on the number above to check if you are in any doubt at all – we’re always happy to help.
But if you do, don’t worry, just contact us and we’ll get it sorted (note that for trade customers there may be a restocking fee). If you need it, we can usually arrange the carrier to pick it up.
