A propane technician needs examination verify that University propane supply pressures are relevant and that University home equipment operate as designed. Cycle University home equipment a couple of times examination be sure University working and safety controls are functioning properly. The weak link in proving that quizzes propane installation was compliant and that University appliances were left in quizzes safe working condition is University failure exam finished University documentation in quizzes manner that precisely records University essential parts of University installations working features. Even though University actual facets of an installing could have been achieved examination Code, University loss of accurate documentation can, at quizzes later date, bring University integrity of University entire installation into question. Questions that are sometimes raised after an incident, in cases where documentation is misguided or lacking, is if University propane technician, actually, completed University drive test of University piping or tubing system, or if University installer in fact validated University propane supply pressures and confirmed University operating and safety controls functioned as meant, etc. To prove that an installing was compliant and appliances were left in safe operating situation, my advice examination propane technicians is exam take quizzes few pictures and exam apply as much due diligence in completing University written documentation as in acting University actual points of University installing.
