For Twin Flues

8.6 For Roof Terminals
1. In the case of a pitched roof 25 - 50 degrees, position the lead tile to replace/flash over existing roof tiling. Make an aperture in the roof suitable for the
lower tube of the roof terminal and ensure the integrity of the roof cover is maintained. The adjustable plastic collar can either be positioned on the
lead tile or the lower tube of the roof terminal prior to the final positioning of the vertical flue through the tile. Check the collar is correctly located to suit
required roof pitch (either 25° to 38° or 37° to 50°). From inside the roof adjust the flue to a vertical position and secure to the roof structure with the
clamp supplied.
2. For flat roof installations the aluminium flashing must be incorporated into the roof covering and the appropriate aperture made in the roof decking. The
vertical flue is lowered onto the flashing making sure the collar of the flue locates securely with the flashing. (A mastic seal may be necessary). From
inside the roof, adjust the flue to a vertical position and secure to the roof structure with the clamp supplied.
IMPORTANT : If the boiler is not fitted immediately after the flue system, temporary precautions must be taken to prevent rain entry into the room of
installation.
Any precautionary measures must be removed prior to commissioning the boiler.
