What it is
The Potterton 5139774 is a silicone door seal for the heat exchanger on Potterton Commercial IHE boilers. It seals the heat exchanger door joint, keeping combustion products and water where they belong. The silicone construction allows the seal to cope with the elevated temperatures at the heat exchanger door.
Signs this part needs replacing
- Water weeping or staining around the heat exchanger door joint
- Visible hardening, cracking or flattening of the silicone seal
- Seal distorted or swollen out of its seating
- Combustion odour or leakage traced to the heat exchanger door
- Seal damage found when the heat exchanger door is opened for service
Before you order

- Check the part number on the existing seal or in the appliance documentation is 5139774
- Inspect the heat exchanger door and its seating for corrosion or damage before refitting a new seal
