A couple of things to clear up about the portable ventless heater:

It does not have an O2 sensor, it just has a calibrated torch flame on the pilot burner that barely touches the thermocouple tip, if the oxygen content of the air gets too low the flame gets lazy, lifts up off of the tip, thermocouple cools, heater shuts down.

That is the Mr. Heater Big Buddy or Tough Buddy infrared plaque heater, it is 4000 (1 plaque low), 9000 (1 plaque high), or 18000 (both plaques high) BTUs per hour.

They are also using the wrong bulk tank hose, the big buddy has 2 regulators built in with threads to connect directly to 2 1LB propane cylinders, it also has a low pressure (11" WC) quick connect fitting. They are using a high pressure hose connected to one of those regulators, not the proper low pressure hose with a regulator at the tank. That hose is only for the regular Buddy heater that only has 1 plaque, and 1 cylinder connection, hence is 1/2 output. That hose also has to be used with an inline oil separator (sold as a filter) that has a male 1Lb fitting on one end and a female on the other. And yes the bulk tank is supposed to be located outside.

The 2 built-in regulators have valves in them that close when the 1Lb cylinder is removed to prevent gas from leaking, and the quick connect is designed like a hydraulic fitting, IE both male and female ends seal when disconnected.

I don't get how it's not producing CO? Or is it kinda like a gas range...plenty of combustion air?

Totally ignored not only co risks, but that the propane tank is supposed to be on the end of the 25ft hose... oudoors. I actually have one of those buddy heaters but have never used it. I wonder if an commercial insurance carrier could flat out deny a claim in a fire if they found that.

Theyh do actuslly have a o2 sensor and tip over switch..and they atre only about 5000btus each I think.... but still a very bad idea.

At least there wasn,t a single kerosene salamander running in. The middle of the room.

You should have checked for CO

It would be hard for him to ignore something BEEPING

Owner of unit- What's that
You- my Alarm to get the ?...... outta hear before I die

That's nuts! Those things are so HOT I melted my Columbia jacket on one.

What the hell is that? A propane fired portable heater? Is that flame glowing?

Oh hell no...

The salt is half empty...



You need to break up with that place. That is scary.

Not bad.. my first one took me 3 hrs fully running and out the door.

I haven't timed a 10 ton or smaller. But with 2 guys we would have that thing out and new one in the unit in less than an hour for sure. Without ripping it all up! Thats not counting checking in, setting up, etc . .

They are the most time consuming. But if you do or have done tons of em, you knock em out . . . While keeping it clean and not ripping up insulation!

Rubber tape with a duct tape wrap to secure never fails. That's probably what's on it with a foil tape wrap for heat deflection

I told him the cost factor for the board he said sounds food but then told him about the price he gonna pay for month he said... wow.. I literally laugh and said think about it and see what you wanna do...

That is a good option but when he gets his bill he'll be blaming you for it.
