FuranFlex Installation Process

The following is a summary to provide insight into the FuranFlex® installation process:

1. PREPARATION FOR THE LINING

  • camera inspection
  • removing foreign objects
  • cleaning if necessary
  • filling of the steam generator with (either ion exchanged or distilled) water
  • connecting the steam generator to the gas bottle
  • turning on the heating of the steam generator
  • Cleaning before Cleaning after
  • Picture of a chimney to be lined before and after preparation

2. PREPARING THE INSERTION

  • Inserting the T-joint
  • FuranFlex® liner tube (5) placement near the chimney
  • Preparing the machines and tools needed for the installation

3. INSERTION

  • Insertion is carried out from top to bottom at smaller chimneys, while at larger ones, from bottom to top with a hoist
  • the liner tube goes through the T-joint (6) and the calibrating ring (7)
  • fixing the adapter heads to the stands
  • connecting the pipe (10) of the fast blowing unit (3)
  • connecting the pipe (12) of the steam generator (1)
  • connecting the returning line of the condense water (11) to the water tank (2)

4. INFLATING FURANFLEX® LINER WITH AIR

  • upper valve (8) closed
  • check all connections
  • commence inflating with the fast blowing unit
  • Beepites Fast blower
  • Inflating FuranFlex® with the fast blowing unit

5. FURANFLEX® HARDENING WITH STEAM

  • set the needed pressure on the steam generator (0.1 – 0.4 bar, lower pressure is needed with larger diameter)
  • blow in the steam of 105 – 110 °C temperature
  • minimal opening of the upper valve (8)
  • monitor the progress of the hardening process, increase steam pressure (maximum value is 0.4 bar
  • close off the steam pressure when hardened, cool down FuranFlex® liner (fast blowing unit may be used)
  • Beepites steam outlet
  • The steam used while hardening the FuranFlex® liner is exhausted through the upper valve

6. FORMING THE ENDS OF THE LINER

  • cutting off the extra length of the tube under the upper adapter
  • cutting off the FuranFlex® liner under the calibrating ring (7)
  • Beepites top cut
  • Forming the upper end of the liner

7. FINISHING WORKS 

  • inserting the cleaning piece (17) on the calibrating ring (7)
  • closing the soot door (18)
  • placing the rain protector (19)
  • Beepites FF finalized
  • FuranFlex® liner with rain protector
