All these user manuals say to avoid carbon monoxide you should vent indoor spaces, but if you start cracking windows all the cold outside air comes rushing in. So what's the proper way to do this - just barely crack a window 1/2 inch?

I use a 20k btu wall mounted ventless propane heater. Get a smoke/co detector and an explosive gas detector. Put the gas detector low and near your heater, propane sinks. If you can, the best thing to do it give the heater its own fresh air intake. I don't have it done yet but I plan on making a small hole in the wall just under the heater and using an HVAC vent cover to adjust the draft. As it stands we've been using it all winter with no issue.
