Step 5. Place the gasket into the gasket pocket with the gasket marking side in first. Refer to the Gaskets section of this manual for an illustration of proper gasket placement.
Step 6. Bring both the Flange Adapter and the opposite Flange together. Ensure proper align- ment and slide each of the remaining flange bolts (not supplied) in the remaining bolt holes. Tighten all nuts uniformly to bring the flange faces firmly together in an alternating pattern.
Note: To achieve proper flange joint connec- tions for the Figure 71 Flange Adapter (2 to 12 Inch), refer to the recommended flange mating bolts torque range listed in the Grooved Cou- plings section of this manual. Failure to use the manufacturer's settings and abide by manufac- turer instructions may result in loss of warranty protection, invalidate listing certifications and/ or cause personal injury or property damage.
• Flange Adapters are not recommended for applications that incorporate tie rods for anchoring, or on standard fittings within 90° of each other. Refer to Tech Data Sheet G150 (Figure 71 Flange Adapter) and G515 (Figure 61 Flange Adapter) for additional information.
• Flange Adapter Washers are required when the Flange Adapters are used against surfaces such as:
1. Rubber surfaces
2. Adapting to AWWA cast flanges
3. Rubber-faced wafer valves
4. Serrated flange surfaces
