"This was a low complexity modification to a existing gas line connecting to a gas range. It took approximately an hour with two staff. One thing I was concerned about was the usage of a lighter to check for gas leaks. Typically this type of checking is done using soapy water as using fire to check for gas leaks can be hazardous."
