Nice job. Don't worry if you don't know a few words, your English is good

I also wrap the tube with exhaust pipe wrap to make sure it doesn’t get hot enough to burn in the wall

I also take copper tubing and coil it inside of the tube and run water thru it to heat water to pool

I have 5 of these i even have one mounted in my shed outside to heat in winter

There is a setting to prime the line but you should fill long line with gravity before attaching the fuel line to pump its lubricant by diesel

These work great
