ASSEMBLY METHOD (Fig 18/19) - High Level Adaptor Kit used with 600mm Horizontal Telescopic BF Kit
Supplied with the kit are two spigots. Use the spigot that does not have chamfered corners. The other spigot is
not required for this installation. Each vertical section of pipe has a different diameter. The lowermost pipes have
the smallest diameter, the uppermost the largest.
To aid assembly, it is necessary to apply a thin bead of lubricant (e.g. washing up liquid or Vaseline) to all flue
joints that incorporate ‘O’-ring seals. As the flue system operates under positive pressure, all flue joints that do
not incorporate ‘O’-ring seals should be sealed with silicone sealant.
Trianco flue kits are designed to incorporate the latest ‘O’-ring seals.
Before commencing assembly, please make sure that all ‘O’-rings seals are in position.
1. Having decided the position of the boiler, cut a 170mm
square hole in the wall.
2. Take the collar piece and slide onto the top inner flue
pipe (identified by lack of plate connection piece at
base), making sure that the stop pieces are closest
to the top of the collar. Line up the holes in the collar
with the holes in the flue pipe and screw the collar
into position using self-tapping screws.
3. Remove the top casing and remove the spigot plate
from the top of the boiler. Place gasket on top of the
boiler and then the inner flue pipe over the gasket.
Use spigot plate (previously removed) as a clamping
plate. Screw it down on top of the boiler, trapping the
pipe and gasket in position.
4. Place outer lower pipe (identified by hose connection
piece) over inner lower pipe (identified by flat spigot
connection at base) and fit onto spigot plate.
5. Fit top inner flue pipe to lower flue pipe, using holes
provided. Fit outer pipes together in same manner.
making sure that top outer and inner pipes are level
with each other.
6. Take the flue box and to the underside of the box
(identified by twelve holes around the square cut
out), fit the flue pipe spigot and gasket.
7. Slide the flue box through the cut out in the wall and
locate outer flue pipe to the spigot on the flue box.
8. Slide telescopic inner flue pipe over inner flue pipe of
flue terminal. Fix flue elbow onto end of telescopic
inner pipe and slide terminal into the flue box from
outside, locating elbow over collar piece.
9. Push terminal inwards. A minimum dimension of
140mm from the wall to the end of the terminal is
required.
10. Fit round sealing plate in position on flue box using
silicone sealant and M4 wing nuts.
11. Fit round sealing plate onto blanking plate and
secure using four self-tapping screws.
12. Make good wall inside and outside.
13. Use clip provided to secure air hose from burner to
connection on flue pipe.
14. Replace top casing.
1. Having decided the position of the boiler, cut a 170mm
square hole in the wall.
2. Take the collar piece and slide onto the top inner flue
pipe (identified by lack of plate connection piece at
base), making sure that the stop pieces are closest
to the top of the collar. Line up the holes in the collar
with the holes in the flue pipe and screw the collar
into position using self-tapping screws.
3. Remove the top casing and remove the spigot plate
from the top of the boiler. Place gasket on top of the
boiler and then the inner flue pipe over the gasket.
Use spigot plate (previously removed) as a clamping
plate. Screw it down on top of the boiler, trapping the
pipe and gasket in position.
4. Place outer lower pipe (identified by hose connection
piece) over inner lower pipe (identified by flat spigot
connection at base) and fit onto spigot plate.
5. Fit top inner flue pipe to lower flue pipe, using holes
provided. Fit outer pipes together in same manner,
making sure that top outer and inner pipes are level
with each other.
6. Take the flue box and to the underside of the box
(identified by twelve holes around the square cut
out), fit the flue pipe spigot and gasket.
7. Slide the flue box through the cut out in the wall and
locate outer flue pipe to the spigot on the flue box.
8. Fix flue elbow onto flue box inner pipe and slide
terminal into the flue box from outside, locating elbow
over collar piece.
9. Measure from the face of the outside wall to the end
of the terminal and subtract 140mm. This will give the
length of pipe to be cut off of the flue terminal inner
pipe.
10. Remove the flue terminal from the flue box and
remove the elbow. Cut the terminal inner pipe to the
desired length and reassemble flue.
11. Fit round sealing plate in position on flue box using
silicone sealant and M4 wing nuts.
12. Fit round sealing plate onto blanking plate and
secure using four self-tapping screws.
13. Make good wall inside and outside.
14. Use clip provided to secure air hose from burner to
connection on flue pipe.
15. Replace top casing.
