13.6.1 To insulate the gas stop valve
The gas pipes and stop valve can reach temperatures as low as –
40°C. For safety reasons, it is therefore necessary to insulate these
parts as soon as all tests are done.
1 Install the accessory insulation tube around the gas stop valve's
body.
▪ Position the accessory insulation tube around the gas stop
valve's body.
▪ Remove the protective tape from between the sealing to
reveal the sticky side.
▪ Gently push both sides of the sealing together to close the
insulation.
2 Install the accessory insulation square around the gas stop
valve's cap.
▪ Remove the protective tape from the square to reveal the
sticky side.
▪ Position the accessory insulation square over the gas stop
valve's cap.
▪ Gently push the square against the tube to keep the square
in place.
3 Insulate the back of the stop valve by applying an insulation
tape (field supplied) around the fixation screws.

DANGER: RISK OF ELECTROCUTION
WARNING
ALWAYS use multicore cable for power supply cables.
CAUTION
This equipment is NOT intended for use in residential
locations and will NOT guarantee to provide adequate
protection to radio reception in such locations.
NOTICE
The distance between the high voltage and low voltage
cables should be at least 50 mm.
NOTICE
If the equipment is installed closer than 30 m to a
residential location, the professional installer MUST
evaluate the EMC situation before installation.
14.1 About electrical compliance
This equipment (LREN* and LRNUN5A7Y1) complies with:
▪ EN/IEC 61000‑3‑11 provided that the system impedance Z
sys
is
less than or equal to Z
max
at the interface point between the user's
supply and the public system.
▪ EN/IEC 61000‑3‑11 = European/International Technical
Standard setting the limits for voltage changes, voltage
fluctuations and flicker in public low-voltage supply systems for
equipment with rated current ≤75 A.
▪ It is the responsibility of the installer or user of the equipment to
ensure, by consultation with the distribution network operator if
necessary, that the equipment is connected ONLY to a supply
with a system impedance Z
sys
less than or equal to Z
max
.
▪ EN/IEC 61000‑3‑12 provided that the short-circuit power S
sc
is
greater than or equal to the minimum S
sc
value at the interface
point between the user's supply and the public system.
▪ EN/IEC 61000‑3‑12 = European/International Technical
Standard setting the limits for harmonic currents produced by
equipment connected to public low-voltage systems with input
current >16 A and ≤75 A per phase.
▪ It is the responsibility of the installer or user of the equipment to
ensure, by consultation with the distribution network operator if
necessary, that the equipment is connected ONLY to a supply
with a short-circuit power S
sc
greater than or equal to the
minimum S
sc
value.
