A. GENERAL INSTRUCTIONS FOR FLUE SYSTEM
▪ Flue pipe installed crimp/narrow end down
▪ Outer casings installed crimped/narrow end up. (Critical
when exposed above the roof)
▪ Inner casings - direction not critical
▪ Flue pipes - seal all joints including firebox spigot.
- fix with a minimum of 3 stainless steel rivets
▪ Flue pipe spacers - affix to flue pipe
▪ Flue system termination point - Refer to AS/NZS
2918:2001 4.9.1, see Fig. 9.
▪ Flue pipe shall extend not less than 4.6m above top of
the floor protector as per
AS/NZS 2918:2001 4.9.1(a)
▪ Façade or chase systems - same rule applies as above.
▪ Roof penetration and flashing method refer to NZ Building
Code E2.(From 01/07/05)
Note: These instructions apply to 150mm diameter flue
pipe systems as tested to AS/NZS 2918:2001
1. Either locate the appliance in position or by measuring at
the ceiling mark the flue pipe centre position. Check that
the outer casing is unobstructed through the attic space
or roof area.
2. Spike the centre with a nail. Transfer this position to the
next surface above. Plumb bob/laser.
3. Cut out the ceiling penetration hole – square or rectangle
– short axis equals outer casing diameter plus 50mm,
long axis as required. See Table 5 . Perform the same at
the roof penetration.
4. Frame out the hole with minimum 75 x 50 timber or as
required for roofing material. Minimum requirement at
roof penetration see NZ Building Code E2 Acceptable
Solution (from 01/07/05).
5. Install the outer casing so that :-
(i) lower end is flush with the underside of the ceiling
material and
(ii) with the addition of metal "L" brackets, affix to the outer
casing at 90 degrees secure the outer casing centrally
to the ceiling and roof nogs. Alternatively substitute
the "L" brackets for 25mm thick non heat sensitive
packers. Secure the outer casing through the packers
with horizontal fixings to the nogs. Refer to the General
Instruction for termination height. The option of outer
casing slips to be taken into account.
6. Flash the outer casing to the roof material with the
appropriate approved flashing.
7. If using an outer/inner casing combination, now install
the inner casing ensuring it extends a minimum 200mm
above the high side of the roof penetration. If not using a
combination see '11' below.
8. Refer to Firebox Installation, points 1 & 2.
9. Prepare the ceiling plate and place upside down over the
flue spigot.

10. Install the flue pipes by preferred method – either up or
down the outer casing. Affix each length per the notes in
General Instructions (above). Extend the flue pipe above
the outer casing to suit the casing cover/cowl assembly.
11. If the inner casing has not been installed, install now.
Refer to 7 above for minimum height.
12. Install the cowl assembly, i.e. Top spacer, casing cover
and cowl.
13. Position and secure the ceiling plate with the screws and
spacers.
14. Wipe the flue pipe to remove finger marks.
15. Refer to Firebox Installation, point 3.
16. If flue offset is required, refer to AS/NZS 2918:2001 4.1
