FLUE SYSTEM INSTALLATION GUIDE
This is a general installation guide only – Contact a “ NZHHA Installer ” 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 spacer around the flue pipe approximitaly150mm above the adaptor collar. Secure in position 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
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 re-
moved 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.
•
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.”
Note: FLUE SYSTEMS casing.
The flue system requires to be doubled lined to comply
with AS/NZS:2918:2001 4.3 Flue pipe casing.
