Boiler precision tune up; clean and tune up boiler; check/verify water pressure, inspect and clean burners, test ignition components, test/adjust gas level, test safety circuit, check motors and pumps, checked all electrical components, checked heating temperatures, test combustion, and tested overall boiler operation. Removed gas line running to the dryer, cut out the crimped section and re-flared this end. Attach gas line to the dryer and the incoming gas line. While reseating the dryer the gas line did slightly twist and cave in, used channel locks to remove the caved in section as best as possible. Tested for gas leaks and once I confirmed there were no gas leaks i got confirmation from the customer that everything looked good.
