Another unfortunate situation this customer did not choose to go with a knowledgeable skilled professional when it comes to boiler installation. Immediate code hazards left behind, improper location for the thermostat, put a takeover controller behind the venting so it can never be serviced, just another disaster that's going to cost this customer another $3,000 in repairs. Don't pay twice contact the company that knows your boiler system.

Gas leaks are serious!! Not to mention a waste of a precious resource. In this situation it looks like the technician did the work was under trained and did not know proper procedures on pressure testing as well as using pipe dope on threads. It is very important that your gas system is installed by a highly trained and highly professional technician.
