Fixx,
For me, I prefer LP over the Kero..........I've been in buildings where both were used - propane fan forced ceiling heaters (CO detector w/ cracked door) may be the lesser of 2 evil's, but a Kero heater gives me a headache imediately even with the sented fuel additives.
I'l be using a 100 pound LP tank (approx. 23.5 gals) not the 20 pound gas grille tank.
Remember it's 200,000 btu's and although it's a convection heater, I still have 2 ceiling fans in the "Mag dome" to push the heat around. After I blast (that's a poor word) up the heat I'll resort to smaller electric heaters for the glassing.
