I am still amazed about not what I saw , but later on by what I heard,fron the HVAC guy.
First of all I had to shut the gas to the water Heater, when I found the control leaking.My tiff went off like a siren near the fanned exhaust too.
drain pan had a hole to the (nothing) just a hole.Bad enough
I look at the HVAC schedule 40 and see it has a intake with one problem.
Now take a closer look if you can.(sorry still on the report to rotate)
This is a Rheem Weather king (high efficiency)
If yoiu can tell , the guy cut it.
My client was gone when I ran into the HVAC guy driving up.
I asked are you here for the gas leak, to which he replied in a thick Polish accent . NO I do only furnace.
Ok great , why did you not hook up the intake vent.
Me hooked up, but City guy say it is not needed because of bifold doors so I go to all units and cut like heem say.
If you look close enough you can see this schedule 40 cut right at the elboes
His lack of understanding English caused this.
