NOTE
Do not bolt one side at a time. Tighten each side simultaneously. Example:
1. Snug left
2. Snug right
3. Tighten left
4. Tighten right
Do not snug and tighten left and then snug and tighten right. Failure to do so
will result in liner damage.
Always check for leaks at the flanges after tightening the flange bolts. Failure
to use the correct flange bolt tightening methods can result in severe damage.
All flowtubes require a second torquing twenty-four hours after initial flange
bolt tightening.
