Suburban LP RV Furnace 19,000 BTU NT-20SEQ 2501ABK

We've just used it once.

To be fair, my shed is well insulated and the whole unit is inside the structure with a large can of sand to absorb the exhaust heat. The wires are easily identifiable. I'd buy another, if I needed it, at the price I paid. Heck, I might make an excuse to buy another. Maybe I should use this in my lithium battery shed instead of electric or pair it with double thermostats so that if the outdoor temperature is below freezing, this will take over the work that the little electric space heater would have done to keep it between 35 and 50. Just thinking out loud. At this price, I'd buy it to heat the inside of a tent rather than using something pricy that was sold just for that purpose. The size makes it better than those big wall-mounted blue flame or radiant heaters. I've only been using it for a couple hours and as long as those sounds it makes after shutting down aren't damage from insufficient cooldown period, I think I'll remain happy with it.

This was a direct replacement with heater in the truck camper. Remove and replace was easy enough but the heater needed longer exhaust and intake pipe so had to use existing which are not as tight as should be.The first time starting - running has a horrible smell that takes a long time to go way. Ran it more than hour total now and still has off smell, hopefully it will go away. Its like a oil-paint burning smell.

Worked perfectly to replace my old standing pilot furnace in my old camper. It is very quite to in comparison to the old one. Would recommend.
