100mm SLOPING CEILING ECO FLUE KIT

THIS FLUE KIT HAS BEEN MANUFACTURED IN ACCORDANCE WITH AS/NZS 2918:2001.

WARNING: TO ENSURE SAFETY THIS FLUE KIT MUST BE INSTALLED AS OUTLINED IN THESE INSTRUCTIONS.
WOOD FIRE AND FLUE PIPE CLEARANCES FROM COMBUSTIBLE WALLS MUST BE IN ACCORDANCE WITH
WOOD FIRE MANUFACTURERS SPECIFICATIONS AND AS/NZS 2918:2001.

CAUTION: MIXING FLUE SYSTEM COMPONENTS FROM DIFFERENT SOURCES OR MODIFYING THE
DIMENSIONAL SPECIFICATION OF COMPONENTS MAY RESULT IN HAZARDOUS CONDITIONS. WHERE SUCH
ACTION IS CONSIDERED, THE MANUFACTURER SHOULD BE CONSULTED IN THE FIRST INSTANCE.

CAUTION: IT IS THE RESPONSIBILITY OF THE INSTALLER TO ENSURE THAT THE INSTALLATION OF THIS FLUE
KIT COMPLIES WITH AS/NZS 2918:2001. THE APPLIANCE MANUFACTURERS SPECIFICATIONS FOR FLUE PIPE
SHIELD AND CEILING PLATE AND THAT THE RELEVANT BUILDING CODES ARE ADHERED TO.

To install this flue design the installer should be familiar with the installation of flue kits for standard ceilings
and have competent carpentry and roofing skills. They should also be aware of the 4.6 metre height
requirements of AS/NZS 2918:2001 and minimum height requirements as per figure 4.9 (Diagram C).

This Sloping Ceiling kit is designed for installations into ceilings with slopes of up to 45 degrees.

All instructions refer to Diagrams C and D.

The flue pipes are tapered to fit the upper section inside the lower one.
Our Full Flow Cowl (ie. no cap), prevents dripping of condensed acids down the chimney.
The flue discharges some 18 litres of water as vapour for each 30kg of dry wood burned.

Do not put a cap on the Pyroclassic Flue System.

Installation

1. To install the Pyroclassic Sloping Ceiling Flue Kit begin by locating the Pyroclassic IV fire (or the

Pyroclassic Raised Hearth if it is being used) in its proposed position, and mark a point on the ceiling that is

directly above the centre of the fire’s flue outlet, (or the hole in the raised hearth). Check the location

allows the Outer Casing of the Thermosyphon Assembly to clear all structural roof timbers.

2. Cut an oval hole in the ceiling and a corresponding oval hole in the roof 250mm wide. Cut the

length to suit the ceiling angle to fit the Ø250mm Thermosyphon Assembly (Use the Ceiling Plate as a
cutting template).

3. Temporarily slide fit an appropriate roof flashing (not supplied) around the Thermosyphon

Assembly outer liner before mounting the assembly.

4. Now mount the Thermosyphon Assembly by lowering into the oval hole and fix to the roof at 4

points, 90 degrees apart, using the mounting brackets provided. Take particular care when lowering into the
oval hole to avoid scratching or gouging the assembly outer liner.
(Note: if you prefer to mount the Thermosyphon Assembly from below, you will need to remove the vent
cowl by drilling out the two rivets installed. The Cowl can be refitted after installation of the Thermosyphon
Assembly).

5. Ensure the 250mm Outer Casing protrudes at least 250mm below the ceiling on the lower side and

is securely installed, (remembering this has to take the whole weight of the outer flue system).

6. With the Thermosyphon Assembly secured in place, lower the flashing to the roof, silicon seal the

edges and fix flashing securely to the roof.

7. Attach the Ceiling Tile with a screw through each corner. Now fit the Dress Ring of the

Thermosyphon Assembly by firmly pressing into the Outer Casing until rim is bottomed. Three rivets is
sufficient to secure the cap in place (you may wish to omit a rivet from the frontal area for aesthetic
reasons).

8. With the Pyroclassic IV fire in position, place the Outlet Cone (supplied with the fire) into the fire

spigot. The spigot has a pre-drilled pilot hole, use this hole to secure the Outlet Cone to the spigot with the
supplied screw so that it cannot be lifted out should the flue accidentally get caught up on something
during the expansion and contraction process.

9. The 100mm S/S flue pipes can now be fitted from inside the room (ensure the Dress Ring is fitted to

the bottom of the 250mm Outer Casing. Ref: para 7). Secure each joint with sealant and three ss rivets
equally spaced around the joints to prevent unintentional or accidental separation.
Once all the required flue sections have been connected, position the bottom length of flue pipe into the
Outlet Cone. (Take care not to scratch the Outlet Cone).

Note: The flue pipes must be assembled with swage roll end down (towards fire).

10. The 200x600mm Liner Assembly can now be fitted by placing over the upper 100mm flue pipe and

fixed to the top spigot of the Thermsyphon Assembly with 4 rivets equally spaced around the
circumference. Slide Slip Liner Assembly over 200x600mm liner and push downwards to expose upper
section of flue. Do Not fix slip liner yet.
