I turned off the gas to my 1968 ranch house while I traveled for awhile. When I called the gas company to turn it back on, the technician said he couldn't for two reason:
- The gas pipe from my hot water heater is 1/2" instead of 3/4". He wants me to change the piping. (Is this really a regulation and wouldn't my house be grandfathered in?? )
- My new HVAC system (2 years old) should have a double wall (Type B) vent instead of a single. This system sits in a crawl space (high enough to stand up in) and vents directly outside through the brick foundation (less than 2 feet away). My HVAC person said that a double walled vent is usually only required if venting is going through an attic or where it travels through wood (walls, celing, etc)
Any thoughts?
