Oh, guy a few blocks away was fixing his own gas furnace and blew up the house. Luckily he was gone, looking for parts.<quoted text>
Being not mechanically inclined is a very good reason to have your gas heating system inspected EVERY fall by a professional. Following this habit has led to my 30 year old gas furnace still working perfectly while other rusted hulks of the same model have been toted off to the junkyard. Nothing substitutes for preventive maintenance, especially on a combustion device. Do it every fall and ask them to inspect all gas piping too.
