The TWPro GREY Adjustable Base Support Ø 125 is an essential component for solid fuel and gas/oil appliances such as woodstoves, gas coal effect fires, oil, and gas boilers, and any other solid fuel appliances. Constructed with an outer skin of 304 grade stainless steel and an inner skin of 316 grade stainless steel, both with a 0.4mm thickness, this adjustable base support ensures durability and performance. The insulation is made from compressed rockwool, providing a density of 200kg/m³, and all parts are fully welded to enhance strength.
With a safe distance to combustibles of 50mm, the TWPro system is HETAS Approved and CE marked, bearing the designation numbers EN1856-1 T600 N1 W V2 L50040 G50 and EN1856-1 T200 W V2 L50040 O20. Installation is straightforward, as the TWPro Twin Wall Insulated Chimney parts are secured together using a Locking Band, and it is crucial to maintain the 50mm clearance from any combustible material like wood or plasterboard.
