## Questions & Answers

**Q: Has anyone used it tent camping?  I'm afraid of fire and fumes, but the cub scouts insist in camping in sub freezing temps!**
A: These are time tested and very safe, when I was a Cub Scout I wished I had one. 
   Whether you buy this or not, if you do, my suggestion is to consider buying the GasOne 50180R or similar propane adapter and bring a larger tank so it doesn't run out by morning.
Not suggest you bring a 20lb propane tank into your tent. But if your not backpacking, a slightly larger 5lb tank equates to waking up in a warm temp rather than the dreaded unzipping your sleeping bag and greeted by mornings cold.

**Q: With an adapter hose can it be used with a large propane cylinder?**
A: Not a problem.  Make a 10"x10" box.  Nail 2x6 together in the shape of a U.  Then put 3/8" inch plywood on top and bottom (3/8" a must on top).  Then make a 2 1/4" hole in the center of the top plywood.  Next screw the main heater assembly into the filter with the top plywood in between (the two should come together snug leaving a very small separation which will allow the heater to rotate with no chance of a leak but still be secure).  Then attach the hose and tank.  This box allows for a large tank to be attached, the heater can rotate and the tipsy problem is gone..  Just remember to turn off the tank first to burn up the gas in the line before turning off the heater.

**Q: Does anybody have trouble lighting this heater? Seems I need to hold the ignition button in for a minute and it really hurts my thumb.**
A: Hey Spike, I agree with Thomas W. Mine wouldn't start on the first try either. You have to hold the ignition button down, wait a few seconds, then depress again. It's kind of a pain, but it works. A more annoying issue for me was wanting to use it in my golf cart, but with every tiny bump, the safety feature kicked in and off it went. So, it is safer for home use. For the cart, I bought the Coleman Catalytic Heater with the special holder that fits in the cup holders. It's more quiet too. Stay warm!

**Q: Can you HANG this from something?**
A: YES you can hang this heater.  It's been done.  https://www.youtube.com/watch?v=AZsVX6mh8O4
