— insulate the liquid and gas pipes separately
— use insulating material that is thicker than 15 mm
— ensure that the insulating material adheres to the pipe
without gaps
— fix using adhesive tape
9
Do not tighten the adhesive tape too much, so as to avoid
damaging the insulation.
9
Avoid partial insulation of the pipes.

In case of use with outdoor temperature above 30 °C and
relative humidity above 80%, increase wall thickness up to
20 mm.
For gas pipes:
— ensure that the material used resists to temperatures up
to 120°C
For liquid pipes:
— ensure that the material used resists to temperatures up
