8.0Flue Options

8.6For 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.

8.7Flue Dimensions

The standard horizontal flue kit allows for flue lengths between 100mm and 685mm from elbow to terminal (Fig. 19).

The maximum permissible equivalent flue length is: 10 metres (60/100 system)

20 metres (80/125 system)

8.8Flue Trim

1.The rubber flue trim supplied may be fitted to either the outside wall or on the inner wall of installation.

8.9Terminal Guard (Fig. 21)

1.When codes of practice dictate the use of terminal guards, they can be obtained from most Plumbers’ and Builders’ Merchants.

2.There must be a clearance of at least 50mm between any part of the terminal and the guard.

3.When ordering a terminal guard, quote the appliance name and model number.

4.The flue terminal guard should be positioned centrally over the terminal and fixed as illustrated.

8.10Flue Deflector (Fig. 20)

1.Push the flue deflector over the terminal end and rotate to the optimum angle for deflecting plume. Secure the deflector to the terminal with screws provided.
