Where to Route Espar exhaust?

Espar furnace exhaust goes through the floor of the van, but I am wondering where would be a good place to terminate the exhaust. Manufacturer says not to terminate under the van because poisonous fumes may collect. Should I duct it through the side of a van body panel?

Mine, that came from SMB, ends up behind the drivers side rear wheel, right below the body. Never had a problem with it there.

Thanks. Erik from Badgertrek said his was under the van too. I appreciate the response.

It's all routed under the van and at the end, the shorter length of pipe after the muffler is poking out the side from under. Like your engine exhaust.

Re: Where to Route Espar exhaust?

Can you use a piece of flex pipe and then route it directly into the van exhaust?

The pressure of the engine exhaust, if run to charge the batteries, could create to much pressure and turn off the heater.

I wondered the same thing. If inserted into the back of the 90 degree bend of the tailpipe, would there be pressure? or venturi effect ? Either way, its surely not desirable to effect the heater function.

I proposed poking through the rocker panel which is double wall, and erik pointed out that the air in there is the same as the air in the wall of the cabin, so therefore an exhaust leak within that section would be bad.

I didn't know there was a muffler for the espar air heaters.

Re: Where to Route Espar exhaust?

I guess I never envisioned running both the heater and the engine at the same time. And now I'm wondering why would you want to do that?

Re: Where to Route Espar exhaust?

There is a muffler for the Espar. Do a search here and you should be able to find it. I installed one and it REALLY quiets it down. I don't think the heater should be sold without one, it makes that much of a difference and it's so loud without a muffler.

Re: Where to Route Espar exhaust?

Does anyone know of a GOOD installation source east of the Mississippi?? Lots of the threads on the heater mention places (or is it place?) in the western part of the country but have not seen any postings for this other area of the country.
