FLUE SYSTEM INSTALLATION GUIDE
This is a general installation guide only – Contact a “NZHHA Installer” or Gas Fitter for
Installation Advice.
1.
Install the first length of flue pipe with the crimped end down, inside the Adaptor collar, ensure that the
flue pipe is sealed into the collar with exhaust sealant. Rivet the flue in 3 places around the Adaptor collar.
Place a bottom spacer around the flue pipe approximitaly150mm above the adaptor collar. Secure in posi-
tion by tightening the screw and nut.
2.
Install the second length of flue pipe with the crimped end down and fit by riveting in at least 3 places
around the flue pipe joint. Ensure that the flue is sealed into position with sealant.
3.
Install the first section of flue pipe liner with the Crimped end up, over the flue pipe and over the spacer
that is fixed to the flue pipe. This spacer will keep the liner concentric about the flue pipe.
4.
Position flue spacer at the flue pipe joint for every length of “Flue pipe” and “Liner”.
Repeat the Steps from 1 – 4 to the installed required height of the flue system. The flue system is to comply with
ASNZS 2918:2001 4.9.1 & NZS 5261/5262:2003
IF FLASHING CONE NEEDED
1.
NOTE:
The last length of flue pipe needs to extend past the liner so that when the “top spider” and the “Flashing cone”
are fitted, that the “flashing cone” and the “flue pipe” are
flush,
or that the “flue pipe” is
5mm lower
that the “Flashing
cone”.
2.
Fit the “Top Spider” into position, ensure that the legs of the spider are fitted inside the liner and that the spider is
positioned hard down onto the liner and tighten with the screw and nut.
3.
Place the “Flashing cone” over the “flue pipe” and press hard down onto the “Top Spider”. (Note that the “Flue pipe”
and the “Flashing Cone” are either flush or the “Flue pipe” is 5mm Lower than the “Flashing cone”.) Ensure that the
“Flashing cone” is clear for the venting from the “Liner” and the “flue pipe”.
4.
Fit the “Cowl” to the top of the flue pipe. The “Cowl”, “Flashing cone”, and the “Flue pipe” can be secured to each
other with the uses of a stainless steel self tapping screw. This will allow the “Cowl” to be removed for cleaning.
5.
Flue system may require Bird Proofing due to the installation and locations, discuss this with your installer for the best
advice.
6.
If the Flue system is installed into a “Chimney Chase”, allow for air vent as close to the top of the chase as practical, or
allow venting through the “Chimney Chase Flashing”. A “Venting Flashing cone” and a 25mm gap around the Liner
with a “Venting Flashing Cone-Spider” can be used. Ref : to Figures ……in this specification.
•
a “the flue pipe shall extend not less than 4.6m above the top of the floor protector.”
•
b “ the minimum height of the flue system within 3 m distance from the highest point of the roof shall be 600mm
above that point.”
•
c “the minimum height of the flue system further than 3 m from the highest point of the roof shall be 1000mm
above the roof penetration.”
•
d “no part of any building lies in or above a circular area described by a horizontal radius of 3 m about the flue
system exit.”
