I sent them a message late last night and I got this reply early this morning :
Your installation is not correct and may create a hazardous condition.
You must utilize the Girard Door kit so you have proper ventilation and the water heater housing and the door/flange assembly must be joined together.
If you look at different van converters (Roadtrek, Pleasureway, etc.) water heater installations you will see they make a frame that allows the water heater to be mounted flush to the side wall.
Per our manual, professional installation is strongly suggested.
I understand that it's much easier for them to recommend the standard installation.
But what I'm proposing is simply sealing off the access side of the water heater exactly like there door does but extending the exhaust tube and air intake by barely 4", the only difference is the extension thru the cargo door. Am I not thinking straight?
