Separate the templates.2. Tape the templates into the selected position.3. Ensure squareness by hanging a plumb line asshown.4. Mark onto the wall (if required) the following:a. The wall mounting plate screw positions (chooseone from each group). Note.Mark the centre of theflue hole as well as the circumference.b. The position of the flue duct hole.5. Remove the templates from the wall.IMPORTANT. Ensure that, during the cutting operation,masonry falling outside of the building does not causedamage or personal injury.1. Cut the flue hole, preferably with a 125mm (5") core boringtool, ensuring that the hole is square to the wall. If the holehas been quite accurately cut with a drill then making goodthe wall faces is not essential as seals are provided atboth ends of the flue. However, both wall facesimmediately around the cut hole should be flat; make goodif necessary. For less accurate holes make good toapproximately 125mm (5") diameter at the 2 wall faces.2. Drill 2 holes for the wall mounting plate with an 8mm (5/16 ") masonry drill.3. Drill 1 further hole above the flue hole for boiler fixing withthe same 8mm (5/16 ") drill.4.
