BALANCED FLUE IN VERTICAL CONFIGURATION (PITCHED
ROOF)
2.9.1
Determine the position of the flue run within the property and the
termination position is correct in accordance with BS 5440. Ensure that
clearances to combustible surfaces (50mm minimum) are sufficient
where the flue run may come within close contact of joists etc.
2.9.2
For a pitched roof installation the following components will need to be
ordered from Metaloterm :-
USCP10
Cover plates (pair)
USKB10
Locking band
US100-10/50-10/25-10
Concentic flue - quantity required
dependent upon flue height required
USDH10
Slope roof flashing
or
USLS10
Lead slope roof flashing
USSR10
Storm collar
USDQ10
Roof support

To install the flue system therefore, make hole in roof, install the
pair of cover plates (USCP10) underneath the roof, put the concentric
flue US100-10/50-10/25-10 through the mounting plate and locking
band until it protrudes by 400mm min, 1000mm max through the
roof. Centre the flue and secure with the roof support (USDQ10) and
screws. (See figure 16 below). Please ensure all joints are taped with
suitable high temperature tape when assembling the flue pipe sections
together.
2.9.4
Put the slope roof flashing USDH10 (or in the case of a tiled roof the
lead flashing USLS10) over the flue and make a weather proof finish.
Seal the opening flue and flashing with the silicone rubber and the
storm collar (USSR10).
