Narrative please

Good catch you can send that to Ben to correct the graphic. I did not see this either so I am sure others would miss that.

I sent it in, should be fixed by this evening.

A bit late in the day & slightly off subject but FWIW:

The gas appliances, i presume, are behind the photographer, therefore, the two vent pipes are not slowly rising but actually dropping as they make their way to the left hand “exit” wall.

There might also be an issue with developed length - depending on local code.

Both vent pipes are touching wood.

Are the vent pipes of a code approved material?

Are there any supporting pipe hangers in place?
