Gas piping

Gas pipe connection is located outside of the main garage. The connection from the energy company is connected to the outside pipe. The first entry into home is through garage wall bottom as in picture. It goes all the way up to media room as it's easy to run the pipe from 2nd floor. So this pipe is taken to 2nd floor. It gets split to different outlets in the following order

1. HVAC unit.
2. Kitchen stove (in the first floor)
3. Back patio (From kitchen stove )
4. Water heater (using kitchen stove pipe)
5. Fire place (first floor) 

 Above picture shows the first split into HVAC and 1st floor.

 The pipe goes down to kitchen area from Bed4 closet

 The above picture still shows the pipes in the 2nd floor. 

 The above picture is taken from the closet area. It's the ceiling view of closet area. The pipes run through kitchen stove and water heater. 

The pipes go to two heaters. 

Above picture shows all different outlets. It lists only 4, but actually there are 5 outlets. 5th one is the fire place.
