Install R622 per user manual. Well built propane regulator. As for the upward vent, my solution was to take two 1 1/4" PVC elbows and a 2" 11/4" PVC nipple, connect them together and then use the 11/4 Knee over slot. The knee is a snug fit and no PVC glue is required. Your R622 will then vent properly as instructed. Remember to always use soapy water to check for leaks.
