interesting top vent open and pro pane heater and I was told you would kill your self. interesting so it is possible and not crazy
you just left the top vent open. Why would a window open not do the same???
like i said interesting.
any one else have a comment why this guy is NOT dead?
Slow... you might want to step back and do more research before you get so excited.
Coleman Pro Cat heater = a propane/platinum CATALYST heater. No flame (other than startup), no carbon monoxide. One does need to, however, leave a 6 inch-square opening for oxygen; the device does consume oxygen.
I've used a similar Coleman model propane catalytic heater: the BlackCat, and it's a wonderful invention!
Again, only these propane/platinum catalyst/catalytic heaters are safe for interior use... although one should never really leave them on while sleeping. Any portable heat source placed nearer to flammable materials (fabric, etc) should never be left on unattended. Use them up until lights out and again as soon as you rise, according to the unit's instructions.
