Reduction of the air intake pipe section and gas output section is strictly forbidden.
Ignore section 4.22 in case of airtight installation.
It must be installed in a room with positive atmospheric pressure (minimum 5 pascals). Never make it
work in depression (airtight rooms or without the due air renovations).
Please note below two kinds of airtight installations:
4.29. "DIFLUX" piping.
The gas outlet and the combustion air inlet are connected to the concentric "Diflux" tube. After the air intake
you will find immediately on the outside, the rest of pipe sections should be in double wall pipe.

For these installations it is highly advised to modify the depression offset, according to the number of pipe

* Check modification over the offset with the stove working on level 1 and 9 during 1 hour, controllong the right
combustión of the stove ( no smoke, no depressure excess, etc).
