Riser Installation Procedures

Step 1.

• Determine riser elevation and required riser combination as per tank installation. STAR risers are available in 6" and 12" height increments. (FIG. 1)

---

Step 2.

• Apply gasket (not included) on the innermost flat ring on the tank surface. Be careful not to allow the gasket to overhang the threads where it would interfere with the thread engagement. (FIG. 2)

---

Step 3.

• Trim gasket 1/4" too long. A properly trimmed gasket is then compressed end to end. Ensure that the gasket is uniformly positioned and makes good contact with the tank surface. (FIG. 3)

---

Step 4.

• Screw the riser into the tank joint, being careful that the gasket remains in position. Properly installed, the gasket should show uniform compression around the entire joint. (FIG. 4)

---

Step 5.

• Apply the gasket on the first riser on the thread portion which is facing up. (FIG. 5). Trim the gasket to connect the pieces end to end. Screw the additional riser(s) into position.

---

Step 6.

• Locate the "Secure Here" hole on the cover and install a tamper-resistant screw (STAR-SSCREW provided) through the lid and into the riser below. (FIG. 6) To secure with padlock, drill a larger hole to accomodate the lock.

Step 7.

• If unable to remove covr by hand, insert 1" OD steel pipe into cover indentations and twist using a shovel handle, pipe or piece of wood. (FIG.7)

---

• To prevent unauthorized access, never install STAR Riser System without the factory provided tamper resistant screw.
• Not rated for vehicular traffic loading.
