EZ-Fit Flexible Vertical Balanced Flues (Red System)

EZ-Fit Flexible Vertical Balanced Flues (Red System)

The Grant Red system is a unique flexible balanced flue solution to nuisance pluming and cold draughts. It is designed for Grant Vortex condensing boilers up to 26kW (90,000Btu/h) and allows an existing masonry chimney to be utilised rather than re-site the boiler and pipework

Features & benefits

 

 The Grant Red System is supplied in a pack consisting of two lengths of stainless steel flexible vertical flue pipe (available in lengths for 6, 8, 10 and 12 metres), a rigid/flex adaptor, telescopic flue (upper and lower), support clamp, locking band, starter section, boiler connector, fixings and screws and a tube of mastik.

Extensions and elbows

The flexible vertical balanced flue kits share the same EZ-Fit flue extensions and elbows as the Grant ‘White System’. This unique quick fit connection arrangement ensures easy assembly thereby reducing installation costs. The maximum vertical straight length of the flue, from the top of the boiler to the top of the terminal, is 20 metres – using no more than four 45º elbows.

One metre of straight flue length should be deducted for every elbow used. If the flexible liner has to pass around an offset inside the chimney, two metres of straight flue length should be deducted to compensate for this i.e. equivalent two 45º elbows. Flue extensions cannot be cut, adjustable extensions should be used where required.

  • Possible to create offsets in straight flue runs by using our 45° elbows and extensions
  • Maximum total flue length = 20 metres (using no more than four 45° elbows)
  • Available in 6, 8, 10 and 12 metre packs
