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.

Quick-fit clamp arrangement helps speed up installation
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
Compatible flue extensions and elbows available for longer or offset routes
Extensions and Accessories
If the installation requires a longer or offset flue route, compatible Grant EZ-Fit Yellow System accessories may be required. These can include:
225mm horizontal flue extension
450mm horizontal flue extension
675mm horizontal flue extension
45° offset elbows
90° elbow kits
Plume diverter accessories, where required
Maximum flue lengths, elbow allowances and terminal positions must be checked against the Grant installation instructions before installation.
Before Ordering
Please confirm that this is the correct flue kit for your boiler and installation before purchase. Flue systems are safety-critical and must match the appliance, output and installation requirements.
Confirm the boiler is a compatible Grant internal or boilerhouse model
Confirm the boiler output is up to 26kW
Confirm the required flue system is EZ90 / EZ90IR Yellow System
Measure the wall thickness and confirm it is between 370mm and 550mm
Check terminal position and required clearances
Check whether extensions, elbows or a plume diverter are required
Confirm the flue is not being fitted to a Grant external module boiler
Important Installation Notice
Oil boiler flue systems must be selected, fitted and commissioned by a suitably qualified oil heating engineer, ideally OFTEC registered. Installation must follow the Grant boiler installation manual, the Grant EZ-Fit flue guide, current building regulations and all relevant flue terminal clearance requirements.
