1. With the vent valve in the closed position, check the clearance between the vent
valve lever 7 and the plastic spacer 8. The clearance should be 0.005 to 0.010 in.
(.127 to 0.254 mm) or about the thickness of this page (Figure 5-18).

2. If the clearance is less than the specification, the valve may leak in the closed
-in. open-end wrench to turn the adjustment lock nut 4
position. Use a 11 /
16
clockwise to increase the clearance.
3. If the clearance is greater than the specification, the valve may not open fully,
resulting in longer fill times. Use a
lock nut counterclockwise to decrease the clearance.

Installation

1. Position the vent valve in the mounting bracket slot. Do not tighten the jam nut at
this time.
The mounting bracket should be between the jam nut and the valve body hex
flats. The valve flow direction arrow should point downward.
2. Align the short vent tube 9 and long vent tube 26 with the proper vent valve ports.
Thread the tube nuts onto the valve and tighten.
Do not overtighten the vent tube nuts. Overtightening may result in a cracked
fitting. Only a slight increase in torque is required to seal up a compression
fitting that has already been made up. For
tight is required when making up a new fitting.
3. Push the vent valve fully into the slot in the mounting bracket. Hold the valve in this
position with a 5 / -in. open-end wrench placed on the valve body hex flats. Use a
8
-in. open-end wrench to tighten the jam nut 3.

4. Install the side covers by reversing the side cover removal procedure (Section 5.2.1).
Check for proper vent valve lever operation after installing the side cover.
Adjust the vent valve horizontally by shifting the valve in the mounting
bracket. Adjust vertically by loosening the two socket head cap screws mounted
in the tabs on the bottom of the bottle and shifting the entire bottle assembly
up or down. Make sure that the vent extension tube outlet is centered in the
corresponding side cover clearance hole.
