6.2. REAR INFILL
A rear header beam will be required if the unit includes infill
to the rear gable frame. For units attached at the rear with
suspension brackets, the rear header is fixed between
valley beams using beam to beam brackets. If fixed at the
rear to an attachment beam (Figure 26), the attachment
beam becomes the header (valley beams are fixed to the
header beam) and if attached on the side the rear header is
fixed to the attachment beam with beam to beam brackets.
Attach end rafter brackets to the rear header beam at
spacing, O, as determined in section 3 using six 10x16
hex head self drilling screws (Figure 23).
Fasten the rafters that form the end gable frame over the
end rafter brackets with a minimum of two 10x16 hex
head screws either side (Figure 23).
Refer section 14 for details of fixing infill panels to gable
frames.
6.2.1 SOAKER FLASHING
In the case of a rear infill panel, a soaker flashing is used to
conceal the existing house gutter, waterproof the rear end
of the gable and neatly finish the base of the infill panel
(Figure 24).
The rear gable frame and header beam are positioned 153
mm from the house fascia in order to accommodate the
standard soaker flashing which is optional with the
Outback unit (Figure 25). The frame is fixed on the rear
header over end rafter brackets (Figure 23).
Fix the standard soaker flashing into position on top of the
back channel and underneath the gutter. Infill panels must
be fixed with split tail soft pull rivets at 500mm centres a
minimum of 20 mm above the pan of the soaker flashing.
This will reduce the possibility of moisture being absorbed
into the sheet.
Refer section 14 for details of fixing infill panels to gable
frames.

Note:
1. If your house gutter is wider than 150 mm a custom made
soaker flashing will need to be ordered to the required
dimensions. The rafter setback will need to be adjusted to
suit.
2. Do not form stop ends at either end of the soaker flashing.
3. Soaker flashing is not to come in contact with the base of
the house gutter.
6.2.2 HEADER FLASHING
When a gable is fixed at the rear to an attachment beam,
elevated to the existing house gutter height, typically a
header flashing is used in conjunction with the rear infill. In
this case, the rear attachment beam is considered a
header, and along with the rear gable frame is fixed as close
as possible (within 5mm) to the existing gutter in order to
accommodate the header flashing. The gable frame is fixed
on the rear header over end rafter brackets (Figure 23).
Fix the header flashing into position over the existing gutter
lip with rivets. Infill panels are located behind the header
flashing and fixed with split tail soft pull rivets at 500mm
centres (Figure 26).
Refer section 14 for details of fixing infill panels to gable
frames.
