I'll chime in again as well. The exhaust pipe can be routed outside through a convenient hole nissan left in the trunk. I attached it to a tow hook in the passenger rear side.
(Paul, would you mind posting my photos if you still have them, the ones I emailed you of my install) thanks.
I tried to make mine removable which it is. I took it all out last week in a manner of 5 minutes, it is that easy. I wanted to check all the connections after a month of use. I didn't not seal the hole shut, there is a bit of space where the exhaust pipe leaves the car. But I have sat in the car for 6 hours while running the heater and my carbon monoxide detector did not pick up any gases, fumes or whatever. It tested at 0 every time.
The heater has a small pulse pump which allows for dfferent ways of installing the whole setup. As creative as you can get. I have a 5kw and on 40° F days, the heater can be a bt too much. But I just crac dwn a window a bit and it's all good. Below freezing, it fits my needs fine.
Next year I may look into installing it under a hood possibly. Goal will be to tap into the heater's ducts ,alowing the air to come out of the car's vents, and be able to manipulate air flow to different settings such as, floor, windshield panels etc. Any thoughts from those familiar with the leafs ductwork routing?
Yes, this was a game changer for me in allowing me to use my leaf even during winter months and not have to rely on my ICE honda. My trips are 40 plus miles, roundtrip. In the summer, I can easy make that trip even when running the ac. But in cold weather, I can barely make it, without any heat. My leaf currently hs 45,000 miles and I lost my 3 bar about a year ago. So probably due to lose one here shortly.
I also started using kerosine for fuel, so it burns very clean. No issues with the heater so far at all.
