Gas Outlet Pipe From Gas Tank To Stove.
Gas collected in the gas collection tank is taken out  from the side of  the gas tank. 1.5" pipe is to be fitted in the gas  tank as the output  pipe. On the other end of the pipe we need to fit a  1.5"to .5" reducer  to increase the pressure of the gas to the stove. An  on off valve is  fitted on the end of the .5"pipe along with a pipe to  hose connector to  connect a hose from the gas tank to the stove.( LPG  and Bio gas stove  are different)
