I put mine under a footrest step. Hot air comes out under the drawer stack. Just make sure it has a cold-air intake path and the thru-floor bit doesn't foul anything underneath.

 

Thanks Steve. That looks close to where I am thinking. My main concern is underneath. Do you happen to have a photo of where yours comes through? Do you know if there might be an issue coming through above the small tank behind gas tank?

 

small tank behind gas tank

that's the evap canister is for the emission

 

someone here, maybe 2 people, installed the heater next to the step, can't find the post at the moment

 

I put my Espar exactly where SteveSS did, coincidently I even used the same exact piece of vent pipe on the install. If I remember correctly it was a 4" hole saw (A real arm breaker to drill if you're not careful!) I added the muffler about 2ft behind it on the same side and the fuel tank on the passenger's side underneath just behind the sliding door.
The added bonus with this location is that it allows a bit of piping on both the intake and exhaust. That helps to dampen the fan noise a bit, as opposed to coming straight out of the heater.

 

I appreciate the feedback, thanks. "Recommended Reading" below showed a couple more threads on the subject. I am including a link to a video for future inquiries that shows the exact location I will use. Oh, and great minds think alike - I too am planning to use the duct end cap for protection.

 

Hi folks, has anyone installed under the passenger seat? Willing to remove the tire change kit. Will be living full time in the van in about a year (retiring) and want to travel North America, so space is a premium.

Thanks in advance.

Underseat is fairly common. I found this link a while back. It applies to 2009+ diesel Ducatos+, but it might be of some help. Also search this forum for tidbits.

 

Hi folks, I noticed that a lot people were installing the Espar B4 (gasoline) in open areas towards the back. Has anyone installed it under the passenger seat (yes, I am willing to remove the tire change kit)? I will be living full time in the van after this, so need to maximize space.

Another reason I’m glad mine is not under the seat: I don’t the hot air directly on my feet when I’m sitting there.

Has serviceability been mentioned yet? Seat would have to be removed. Not a huge deal, but a part of the equation.

 

Yes @MsNomer ,,, I mentioned serviceability.

I won’t pretend I even know what the serviceability would be like under the passenger seat, because I don’t.

My serviceability comment is referenced in regards to the entire system & easy access to it. I know where the aux gasoline fuel pickup is & I know where the passenger seat is, but I do not know about the wiring, fuel lines, or the dose pump locations & if they are a PITA.

I do know about performing work on aircraft, on my back in tight spaces while being contorted in different directions & that has my big frame complaining about the design engineers & needing massage therapy.

@SteveSS has factory swivels so he does not get an under passenger seat choice, but he is experienced with the serviceability equation & I wonder if he had the choice, would he go under seat with his heater?

With my building experience, & knowing I will be doing the maintainance, the easy of the installation & serviceability are huge factors to my designs.

 

My thinking was much more mundane—like having to take the seat off to get to the unit.

 

Ya know, I remember watching them put “Neil” onto the moon a few years ago ,,, & the idea of cobbling together whatever they had inside The Apollo 13 in order to “lunar gravity slingshot” those brave souls into The Pacific Ocean

Ya think we could buy a decent van heater that comes with zero issues (including altitude). 🤷‍♂️
