3.2.6 Installation Instructions

1. Thoroughly clean all ange surfaces removing all traces of any old gasket material or

any adhesive residue.

2. Inspect all ange surfaces for warping, pitting or other surface imperfections that may

prevent a good seal.

3. Use new bolts, nuts and hardened washers. ONICON recommends the use of B7 nuts,

bolts and washers. Prior to installation, lubricate the bolt threads, nuts, washer faces

and the underside of the bolt head with lubricant (Fel Pro C5A or equivalent). This

lubricant is necessary to ensure uniform stress distribution on the sealing surface. Use

care not to get any lubricant on the liner or gasket material.

4. Center the new gasket on the liner surface. Do not allow the gasket to protrude into the

ow stream.

5. Use the torque specications shown below to determine the recommended nal bolt

torque requirements.

6. Using a torque wrench, tighten the bolts in at least three stages (30%, 60% & 100%)

using a repeating pattern sequence shown in the diagrams below.
