The initial situation: The LPG tank is outside the building, the gas equipment is inside. The problem: In order to connect both with each other, we have to go through the house wall in one place. The solution: a wall duct for the piping \u2013 if necessary even with integrated main shut-off device.<\/p>\n

The Technical Rules for LPG (TRF<\/strong>) say, under point 7.2.12 “House lead-ins”:<\/p>\n

\n

“For house lead-ins above the soil, piping can be guided through the outside wall of the building with a protective pipe.”<\/p>\n<\/blockquote>\n

The TRF specifies this in more detail under point 7.3.3 and also shows an example of a “manufactured house lead-in”.<\/p>\n

<\/span>No undesired fiddling around at the wall duct<\/span><\/h2>\n

Theoretically, you could also create a core bore and lead a protective pipe through the wall. The disadvantage here:<\/strong> Depending on the professional skills, the whole thing can quickly turn into fiddling around \u2013 and this should be avoided in any case when it comes to handling LPG.<\/p>\n

GOK offers a wall duct for installing a neat solution which is tried and tested in practice<\/a>. The installation requires a core drill hole in the wall with a diameter of over 50 and a maximum of 110 millimetres.<\/p>\n

\"Mit<\/a>
With the wall duct marketed by GOK for LPG piping, you will meet the requirements from the Technical Rules for LPG (TRF).<\/strong><\/figcaption><\/figure>\n

<\/span>The same work step inside and outside<\/span><\/h2>\n

Then, slide the pre-assembled plastic protective pipe through this bore and tighten the flange<\/strong> against the inside of the wall. Then, perform the same work step for the outside: Attach the flange to the house wall and fix it in place.<\/p>\n

At each of the flanges, you will find a filling opening, which becomes important in the next step. Now you have to seal the space between<\/strong> them, for example with silicone or another suitable filler. This is how you insert the protective pipe firmly into the masonry.<\/p>\n
