More Information

Make boiler installations quicker, cleaner and more reliable with the Grant EZ90 Flue System, a low-level balanced flue kit designed specifically for Grant indoor oil and condensing boilers up to approximately 26 kW (90 BTU). This complete flue assembly delivers a room-sealed combustion path with combustion air intake and exhaust pathways in one unit — ensuring safe operation, reduced draught dependencies and efficient flue gas discharge to the outdoors.

The EZ90 kit features a telescopic stainless steel flue design with self-sealing ducts and a quick-fit clamp arrangement that eliminates the need for silicone or tape at joints, helping installers achieve a positive, airtight seal every time. Its compact stainless steel terminal and guard provide neat exterior detailing, while the modular assembly allows adjustment to suit a range of wall thicknesses.

Designed to work seamlessly with Grant boilers in internal plant rooms, boiler houses and utility spaces, the EZ-Fit system reduces installation time and helps maintain compliant, balanced combustion performance even under exposed conditions.
