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.
