The 500 Magnum Firechest with Damper, a part of the Isokern range from National Flues, is designed for those aiming to construct a neat and efficient fire opening up to 1.2m wide. Delivered as a flat pack, it ensures easy and quick assembly, allowing you to set up a preformed fire opening ready for finishing. Made from pumice, a natural insulator, this firechest provides remarkable heat insulation.

Pumice's insulating properties enable the flue gases in the chimney to reach their optimum temperature swiftly, contributing to the appliance's optimal performance sooner after lighting. It also maintains the chimney's warmth for extended periods as the appliance's heat output decreases, enhancing performance while reducing condensation and soot build-up. The Isokern DM system is HETAS approved and CE marked, ensuring top-notch safety and efficiency.

Please refer to the installation guides for complete instructions.
