7.7.9 Reassembly of the SuperFlow 350 Demand Regulator

NOTE: Use the blow-apart in the back of the manual to help ensure correct assembly.

1)Install the exhaust flange, gasket, and screws onto the regulator body. Use Loctite 222 to secure the screws. Tighten the screws to 6 inch pounds.

2)Trim off any excess material from the gasket that might interfere with the operation of the exhaust valve.

3)Install the new exhaust valve into the regulator and trim off any excess stem that may interfere with the movement of the lever or inlet valve.

The gasket must be installed between the flange and regulator body.

Be sure to use Loctite to install the screws in the regulator body.

The screws that hold the flange on the regulator body should be tightened to six inch pounds.

If the flange is tightened too much, the gasket will protrude into the exhaust valve opening and interfere with proper regulator performance.

The exhaust valve is installed on the outside of the flange.
