Yes, You definitely need to exhaust the machine outside more for noise than smoke and fumes. It sounds like a small jet engine as it's firing up, rather cool...for a cost, you can buy one with a muffler but I don't think it's needed.
See the accessory to vent it I used.
The unit runs off of 12volt battery that can be maintained from a charger, solar panel, or engine alternator. I'll be hooking mine up to a 25w solar panel I have from Harbor freight. It consumes 12 Amps to fire up then it settles down to around 3-4 Amps.
I had to put a new battery in remote...
Here is my review I wrote on in Amazon. It has its place for a good price.

It definitely puts out the heat especially if you turn up the pump on high, but on high you can almost watch the fuel drop in its small tank. I don't know but I bet it would run out of fuel in 4 or 5 hours on high... Unless you normally have access to diesel fuel, you'll find that to be annoying too.
Instructions are worthless as others have mentioned. I haven't figured out how to set the timer feature yet.
My REMOTE doesn't work.
The pulsating pump is annoying and noisy.
As someone else suggested, I blew out the pump with air before use, it had odd looking fluid come out of it.
As of this writing, my thoughts are I'll mount it inside my workshop venting the exhaust out the wall, and probably always use it on the low setting jus so I'm not adding fuel to it every time I go out there.
Be aware too it has to have a 12volt supply to operate. A small garden tractor battery didn't cut it, I had to connect a 6amp battery charger to that battery to fire up the heater. No matter what battery you use, it'll need a source to keep it charged as or between uses. I'm going to use a deep cycle rv battery connected to a 25 watt solar panel.
I would have scored it higher if my Remote worked, the Instructions actually instructed, and the pump wasn't so noisy.
Now....
Would I mount it on my camper? Nope.
In a vehicle? Nope.
In my house? Nope.
It's a great heater for the garage, workshop, or porta potty, that's my opinion.
