is there any advice I need . I will cut a vent in door for the vent . I have electric now and we do a lot of boondocking so I don't wanna use generator just for water... I wish I had ordered ventless but I didn't so cutting hole is solution I guess..any other suggestions ... I haven't opened box yet , we'll im not even home my wife says it is home now

I installed the new marey tankless water heater. It works amazingly !!

Where does the hot exhaust gas go in a ventless system?

I dont know . Mine is not ventless. Mine vents out the side of coach.
