The recent tragedy that resulted in the death of a father, son, and grandfather from carbon monoxide poisoning brings to mind a question that I'm sure others have asked themselves before. That is, how much ventilation is needed when using a propane heater.

The industry standard is 1 square inch of ventilation for every 1,000 BTUs of heater output.

Sound correct?

you pretty much have ot think of air as a liquid, and how much ventilation would you need if you were trying to fill the area with water given enough time...it doesn't take much. and in most situations, anything is better than nothing. A small leak of air will fill into a CO2 rich environment so I would guess your 1 sq inch/1000 btu is pretty accurate.

I don't know an exact figure but I keep at least 1-2 windows open in the blind anytime I'm using a heater. If I close the windows I just turn the heater off.

when I use mine at the cabin, I have a window cracked to allow fresh air. I know when the heater buddy runs out of fuel, the cabin cools off pretty good from that window being cracked. But after the incident from this weekend, I believe I will take a CO2 detector with me and place in the cabin for now on.

That sounds about right, my motor home has a built in furnace and the door has a window with a permanent opening across the top about 18"w x 1.5". I believe this opening is for venting.

Also many years ago I installed a wood stove in my mobile home and had to install a special vent kit to meet the code. It was about 3"x 6" and went from the firebox thru the floor and drew air from under the trailer so that the fire would not suck all the oxygen out of the living area.

Yea I just bought a new detector for my trailer at the lease. $25 bucks on Amazon and will be here tomorrow for this weekend.

I have a large Dearborn heater in my cave. Itís a very tight insulated building with a garage door. I also have a CO detector in there. Iíve run several hundred pounds of propane through it over the years with no complaint from the CO detector. I figure the garage door leaks enough to ventilate the building.

Now, is it possible that my heater is just tuned correctly and does not emit CO? Doesnít the absense of a yelllw flame mean itís burning clean?

I've been thinking about this as well. I run an 80,000 btu propane heater, but my shop has two ridge vents and 3 roll up doors that do not come anywhere close to sealing tight. No problems running the heater yet, thankfully, and if 1" per BTU is a good rule, with the gaps in my doors there is more than enough fresh air leaking in.

Regardless, even though I don't sleep in shop and most time would think I am aware enough to notice a change, I am going to go buy a CO (fixed) detector just because.

I can not advise someone on something this potentially dangerous.You should get advice from a propane supply company.

I ran a buddy heater in my old camper many times. I just cracked a window and opened a roof vent. I also installed a CO detector to be extra safe.

If you stay awake an excellent CO detector is you!!! The first sign of a head ache, turn the heat source off and open whatever will get fresh air in cold or not! Sleeping is a different story!!!!

I used to run a 20 lb propane with dual burner
In an 8x20 cargo trailer

Heater is set by the door
I cracked the door 1"
With smoke alarm high on ceiling
And CO alarm at cot height

Everything went fine

Until one day I decided to run propane lantern
Inside with the heater going

Almost died and gone to heaven That night

CO alarm alerted me at 2 am

Where I was having shortness of breath

Thought I was having a heart attack

Then alarm goes off

Heater with cracked door is ok
Never run lantern inside without the door half open

Carry on

All good information. Anyone think of a wall mount heater or even floor heater that has external vent that could be used in blinds, trailer, cargo box. I know electric would be the best answer but.

They make propane heaters that are vented, if properly installed and maintained there would be no problem. Unfortunately there are some people think they are qualified to install and maintain them.
