What Is a Low-Level Balanced Flue Kit?
A low-level balanced flue kit allows a compatible oil boiler to discharge combustion gases horizontally through an external wall. The balanced flue design also draws combustion air from outside, creating a room-sealed flue system that helps keep boiler operation stable and independent of the room air supply.
This type of flue is commonly used where the boiler is installed indoors or in a boilerhouse and a low-level wall terminal is the most suitable flue route.

- Self-sealing joints help reduce installation mess
- No silicone or tape required on standard flue joints
- Compact terminal provides a neat external appearance
- Terminal guard included for additional protection

Extensions and Accessories

- 225mm horizontal flue extension

- Plume diverter accessories, where required
Maximum flue lengths, elbow allowances and terminal positions must be checked against the Grant installation instructions before installation.
