TECHNICAL DATA
i. It will be necessary to fit an adapter in the Flue pipe connection to increase the Flue diameter to the required
minimum Flue diameter of 150 mm (as previously stipulated) to comply with U.K. regulations
ii A Draught stabiliser (by others) should be fitted to the flue to maintain the required flue draught.
STREBEL recommends pellets with a diameter of 6 to 8 mm and length of 10 to 30 mm to
DIN ENplus A1 as referred to in EN 14961-2 A1
