The heater should be installed on a wall of flat non- combustible material that will not reverberate. Whatever the thickness of the wall, make a hole 305 mm (12 in) wide by 205 mm (8 in) high. If the hole is cut accurately there is no need to line it as the wall liner will seal off the cavity. A minimum clearance of 80 mm (3,2 in) should be left above the top edge of the wall opening. For dimensions and clearance see page 2 and Technical Data, page 3.
Slide the wall liner through the walI ensuring that is horizontal and that the flanged end is flush with the face of the inside wall. Trim to length if necessary, so that the outer end of the duct is flush with the face of the outside wall. Make good around the wall liner if necessary (fig. 1). N.B. : For walls of between 75-100 mm (3-4 in), turn the wall liner hooks down through 90”.
Remove the flue bend from the top of the heat exchanger by releasing the fling clip and removing the two screws. N.B. : If the optional top fixing bracket is to be spigot of the appliance in the wall liner, check that the appliance is vertical and mark the four or five fixing holes. Drill and plug the wall and fasten the top studs in position. These studs can be screwed into the wall by locking two nuts together on the parallel thread and using a spanner.
