Vent Box
•
With the top cap of the vent box removed, insert the bottom end of the vertical pipes
into the gap and manoeuvre the vent box up into position, behind vertical pipe assembly
as shown in Figure 11, ensuring the base edge makes contact with the forecourt ground.
•
Place the top cap into the gap of the vent box. Ensure the cap is fitting correctly into the
recess.
• Seal the cap from the inside using 50mm wide aluminium tape to provide a vapour seal.
Also tape the top of the vent box to the column (refer to Figure 11).
•
Using a Bostik Matrix 600 or 700FC polyurethane sealant, seal all joints and pipe holes.
Ensure a good sized fillet at the intersection of the vent box to the forecourt.
Note:
Ensure the inside of the vent box assembly is sealed sufficiently to eliminate the
potential to leak out into the inside of the dispenser cladding.
