| style="border:0.75pt solid #000000;padding:0.071cm;"| Once this is done, fix the main gas pipe of 1 inch diameter, on the top of the dome.

To do this--

Hold the pipe with the external thread on the top.

Insert the pipes between the holes of the 3 chicken layer(s) and rotate slightly.

Check if it is firmly placed.

The pipe will be fixed permanently in this position when the outer wall of the dome will be plastered.

Remember: the external thread on the gas pipe, will help fit the hose pipe firmly.

Arrow at the inlet pipe and the base to keep mixing tank

| style="border:0.75pt solid #000000;padding:0.071cm;"| On the side of the dome adjacent to where the mixing tank will be placed-

* make a firm base. These base should be 4 feet and 5 inches higher than the dome for placing the mixing tank.

* next, on the side of the dome facing the base of the mixing tank cut chicken mesh

* Use scissor to cut the mesh and make hole of 6 inch diameter.

* Through this hole, one end of the inlet pipe will be inserted at an angle of 45 degrees.

* Rest the other end of the inlet pipe at the base of the mixing tank and plaster it with cement mixture.

The pipe from the dome towards the kitchen has to be shown in red
| style="border:0.75pt solid #000000;padding:0.071cm;"| The gas conveyer pipe from the dome to towards the kitchen should be always in an upward direction.

If so, water accumulation inside the conveyer pipe is negligible.

|-
| style="border:0.75pt solid #000000;padding:0.071cm;"|
| style="border:0.75pt solid #000000;padding:0.071cm;"| This brings us to the end of this tutorial about laying the foundation of a Biogas plant.
