Discharge flange

  • Ensure the end of the gutter is clean and dry. Blow dry with heat gun if damp
  • Roll liner to the end of the gutter ensuring the liner is pressed firmly into the gutter creases. This will prevent air pockets and form a solid base to weld the discharge flange to the liner
  • Pin the liner tight into the crease lines either side of the gutter. Two pins on the gutter sole 35mm from the crease line and two pins on the gutter slope 35mm from the crease line
  • Using the 200mm rule pin the liner every 200mm across the gutter sole and up the gutter slopes if required
  • Ensure Sharmans Fixing Caps are installed over all fixings prior to welding
  • Place the discharge flange on top of the liner ready for welding
  • The weakest point of any weld is the crease lines on the gutter sole. Weld at these points first ensuring the discharge flange is pressed firmly into the gutter creases
  • Fully weld the flange to the gutter sole followed by the gutter slopes
  • Allow the discharge flange to cool before probe testing the welds
  • Any un-welded area’s will have to be re-welded and again probe tested once cool
