Connecting The Piping - Extraflame 004281792 Manual De Instrucciones

CONNECTING THE PIPING

10 m of piping with an internal diameter of 50 mm, made of flexible, high-strength antistatic PU with anti-wear characteristics is
supplied, which, if suitably connected to the electrical earthing system, also guarantees protection against the presence of dangerous
accumulations of static current.
Connect the piping between the SUCTION module and the DOSING UNIT, taking care to:
• Use only antistatic piping.
• Connect the fuel suction piping from the IN point of the SUCTION module to the IN point of the DOSING UNIT (figures 1-2).
IMPORTANT: the first horizontal section of the SUCTION module MUST NOT be less than 1 metre long. Each vertical section
must be preceded by a horizontal section at least 1 metre long.
• Connect the air return piping from the OUT point of the DOSING UNIT to the OUT point of the SUCTION module (figures 1-2).
• Avoid joints and fittings in the pipe sections.
• All pipe joints must be airtight and must therefore be carefully tightened.
• Do not exceed the maximum length of 5 m for each of the pipe sections.
• Very long sections must be carefully secured to the wall or to strong supports, at least every 1.5 m.
• There must be no oblique sections, only vertical and horizontal ones.
• Any vertical pipe sections must not exceed a total of 3 m.
• The pipes must not have bends with a radius of less than 50 cm.
• Place any in-wall pipe sections in a casing pipe with a diameter of at least 80 mm.
• Earth each pipe section to avoid dangerous accumulations of static current, using the copper wire around
(figure 3)
THE WEIGHT OF THESE PIPES MUST NOT WEIGH DOWN ON THE DOSING UNIT LID; THE PIPES MUST THEREFORE BE ANCHORED
AT SHORT DISTANCE TO A STURDY SUPPORT.
