This does a great job. Sounds like a jet engine when lit. Be very careful when you open the valve to your tank. Open it very slowly. If you open it too quickly a safety feature within the torch greatly reduces the amont of gas. You only get a yellow flame. If this happens shut off the valve on your tank and open the valve on the torch. Then shut valve on torch and slowly open tank valve.

Mr. Heater, I purchased this at Tractor Supply. I couldn't find my receipt, so I decided to do some troubleshooting. I could get air all the way up to the Open/Close valve, but could not get it to flow to the end of the burner. I took the device apart, including removing the open/close assembly. I could blow air from the open/close assembly back through the hose to the tank. However, I could not get air to flow from open/close assembly out to the burner. I tried to unscrew the pipe from the open/close assembly, but you glue them into the open/close assembly. So, I broke the open/close assembly when trying. However, I cut the pipe off of the open/close assembly and immediately saw what was blocking the propane from getting through the open/close assembly. Seems that when you glue the pipes when you screw them in, you must use an excess of glue and it hardened and blocked the hole for the outlet to the burner torch. I used a small self taping screw on that end and screwed through the glue. Then, I could blow air through the entire length of the hose to the torch. I kept thinking it was the POL end and the pressure switch shutting down, but I kept backtracking by blowing air through the line until I get to that point. I broke my torch in the process of fixing it from your flaw. I would really like a new torch end.
