Gary Yeoman, project engineer with Fluestax, which designed and installed the flue systems, says, ‘System 500 offered the best solution for the Optima building as it serves both condensing and conventional heating appliances. It is also a very reliable system and quick to install.’
System 500 is suitable for both condensing and positive-pressure applications. It incorporates a double-seal push-fit jointing system for ease of installation. The insulation cavity contains 50 mm of solid mineral wool to retain heat and improve draught.
