1. Lubricate nuts, bolts and washers with a graphite/oil mixture.
2. Assure that the ange surfaces are clean and free from damage.
3. Centre the gasket properly over the ange. In retrot, use a pry bar to spread the ange apart
enough that the gasket will not be damaged when sliding in place.
4. Install all ange nuts and bolts.
5. Hand tighten.
6. Utilising a torque wrench, tighten all bolts to 20% nal torque specication following a “star”
pattern. (This means do not tighten bolts in order as a clock. This will result in a poor seat
between 12 o’clock and 1 o’clock.)
7. Tighten all bolts to 40% nal torque specication following a “star” pattern.
8. Tighten all bolts to 60% nal torque specication following a “star” pattern.
10. Tighten all bolts to 80% nal torque specication following a “star” pattern.
11. Tighten all bolts to 100% nal torque specication following a “star” pattern.
12. Following a sequential pattern, ensure that all bolts are tightened to 100% nal torque
specication.
13. It is important that all of the bolts are checked and re-torqued after the anges have been
heated and cooled down for the rst time.
