You can use the Glow-Worm 500mm Flue Extension between flue elbows, vertical adaptors and vertical terminals when you need to extend a length of standard horizontal flue pipe. It gives you more control over the plume exhaust gas exit location, so you can avoid neighbouring properties and other unsuitable areas.
• 60/100mm concentric system
• Suitable for use with all Glow-Worm high efficiency condensing boilers
• Simple to fit, can be installed horizontally or vertically
