4. If an offset is required, an adjustable telescopic type is recommended.
Measure the amount of offset required and adjust the telescopic offset
to suit, after smearing an adequate amount of Pioneer fire cement onto
the slip section of the offset to ensure a good seal, then rivet the offset
in three locations around its circumference. (If the offset is used in its
fully compressed form, it will be necessary to modify the end of the
female slip section otherwise it will restrict the internal diameter) Apply a
liberal amount of Pioneer fire cement into the flue outlet of the fireplace
insert, and fit the lower crimped end of the offset into position inside the
flue outlet, and bolt into position.
Note: In some installations where it is not possible to fit offsets or rigid
flue pipe due to the shape of the masonry chimney cavity, ‘Flexi flue’
may be used.
5. Secure the flue pipes together and ensure the flue seams are staggered.
Flue pipe joints must be fully compressed with a considerable amount
of fire cement to ensure a good seal, and then riveted together at three
even points around the flue join. Prior to installing the assembled flue
pipe into the masonry chimney cavity, take careful note to ensure there
are no overhead power lines in close proximity.
6. Lower the flue pipe into the masonry chimney, with the crimped end
fitting into the fireplace insert flue outlet/offset, and securely attach
with three rivets (offset/bend must be riveted to the flue pipe). For
installations where extra lengths of flue pipe are required, or when the
weather is poor, it will be easier to assemble the flue pipe lengths as
they are lowered into the masonry chimney.
7. Secure the outer casing to the masonry chimney with suitable fasteners.
A masonry chimney flashing plate will be required to weatherproof/seal
the masonry chimney top. Note: The top of the outer casing must be
‘level’
(+ or -10mm) with the top of the 150mm stainless steel flue pipe.
8. Assemble the ECO Cowl as follows;
- Take the stainless steel weather butterfly (A) so the angled sections are
facing up.
- With both arms and angled sections of the stainless steel weather
butterfly (A) facing up, fit it into the stainless steel ECO Cowl top (B), and
secure in position through the holes provided with stainless steel rivets.
NOTE – Once fitted the weather butterfly will be slightly angled within
the cowl housing.
- Fit the ECO Cowl top (B) into the ECO Cowl housing (C). Push both
sections together until the swage ring on (B) rests completely on the
open end of the cowl housing (C). Drill through the two pre-punched
holes in the ECO Cowl housing and secure these two sections together
with stainless steel rivets.
The removable section of the ECO Cowl is now fully assembled.
9. Making your way back onto the roof, fit the 480mm long flue pipe
extension/flashing cone (D), with the flashing cone at the bottom. Fit
the short flue section inside the top of the already installed 150mm
diameter flue pipe. Ensure the three brackets extended below the
flashing cone fit ‘outside’ the outer casing slip section. Drill through the
pre-punched hole in all three brackets into the outer casing slip and
secure with rivets.
10. Taking the ‘removable section of the ECO Cowl’ assembled in section (8)
above, position it over the top of the stainless steel flue pipe extension,
and slide it down fully. This removable section does not require riveting
and therefore enables easy removal for future flue cleaning.
Ultra Insert Flue Kit Installation Instructions
The Metro ECO Flue Systems comply with AS/NZS2918:2001 and its
4.6 metre height requirement (4.6 metre minimum from the top of the
floor protector to the top of the flue pipe). However as external structures
and the proximity of other buildings will differ for every installation, some
situations will require additional flue height to comply with the standard. Refer to the diagram below. (All measurements in mm).
Note: AS/NZS2918:2001 Section 4, details flue system installation
requirements in full.
