The 950 Magnum Firechest with Damper is part of our premium Isokern range, designed for efficient and safe heating solutions. This firechest, supplied as a convenient flat pack, is easily constructed to form a precise and preformed fire opening ready for your personalised finishing. The Magnum variant allows you to create expansive fire openings up to 1.2 meters wide.

Installation of the 950 Magnum Firechest is straightforward yet demands precision. The product is supplied as a flat pack with detailed instructions included in the packaging. Ensure you follow these steps for optimal performance: 1. Inspect all flat pack components upon delivery to confirm nothing is missing or damaged. 2. Carefully read the installation guide provided – it contains vital information regarding proper assembly, orientation, and safety precautions. 3. Assemble the firechest as instructed, ensuring that all parts are securely fitted. Use the recommended tools to avoid damaging the pumice material. 4. When positioning the firechest, adhere to clearance requirements, especially maintaining a 38mm gap on offsets for the DM System. 5. Once assembled, inspect the unit to ensure it is level and properly aligned with the flue system. A poorly aligned installation can impact performance and adherence to safety standards. 6. If you are incorporating additional optional accessories, such as custom trims or enhanced dampers, ensure they are compatible with the primary installation. Caution: Do not modify the structure or use non-approved accessories that could compromise safety and efficiency. For complex installations or if any doubts arise, consult a professional installer or contact our support team.
