INSTALLATION INTO WALL CAVITY.
The minimum wall cavity depth required is 450mm. Select a
pair of studs in front of which the heater is to be installed. The
gap between the studs should be no less than 345mm and no
greater than 610mm. Ensure ceiling and roof members will not
obstruct vertical path of flue.
METHOD.
1. Cut flue opening central to wall studs in the wall cladding.
2. Cut away top wall plate and any existing noggins between
studs.
3. Cut clearance hole for 100mm diameter flue pipe in the roof.
4. Fit header assembly into flue opening leaving a 12mm gap
between top of the header assembly and wall cladding as
shown. (see Fig 6).
5. Drill 4 holes through header flanges at stud centres and use
clouts or screws to attach to the wall.
6. Measure distance from floor to top of flue outlet of the
heater.
7. Adjust elbow to the distance measured plus 2mm and
tighten screw. Ensure flue elbow is horizontal.
8. Bend tabs in at the base of the twin skin flue and lower twin
skin flue down the wall cavity.
9. Slide top plate flue support over twin skin flue, centralise
and nail to the top plate.
10. Slide flue adapter inside inner skin at top of twin skin flue.
11. Fit small end of the 100mm dia flue pipe into flue adapter.
Fit further lengths with small end downward as required.
(The small end has a swage 35mm from the end).
12. Flash between flue pipe and roof cladding using either lead
flashing or an approved silicone rubber pipe flashing boot.
13. Fit cowl to the top of the flue pipe, align the screw holes and
fasten the 3 screws supplied.
