2. Locate mounting surface with thickness up to 3/4 inch maximum
3. Drill 3/4 inch diameter hole in mounting surface

5. Remove vent head and splash guard assembly
6. Insert threaded end of elbow through mounting hole, and apply bedding compound around outside of mounting hole
7. Remove splash guard from vent head, and attach vent head to threaded portion of elbow, tightening securely to insure proper seal. NOTE: Nut and washer must be moved back far enough such that vent head bottoms out on the threaded end of the elbow (not the mounting surface) to insure proper seal
8. Align elbow to suitable orientation, with regard to vent hose path
9. Tighten nut and washer to inside of mounting surface
10. Attach vent hose to barbed end of elbow, and secure with a hose clamp
