Flue length
Total flue length can be 7.5 m—the elbow component of the ASPKIT03/EVOKIT03 is counted as
a 90° bend. If bends need to be included to offset a stud, noggin etc., the flue length can be up to
5.5 m and contain two 90° bends (two ESBEND kits).
Steps for creating vertical in-wall flueing
Lubricate all inner pipe o-rings with the silicone grease provided.
1. Join the flue transition and condensate together ensuring the arrow points upwards.
2. Fit lengths of ESPIPE900 as required.
3. Determine the location of the roof or ceiling penetration point. To avoid obstructions an offset
can be created using the ESBEND kit.
4. Create a vertical roof terminal.
5. Secure joints between flue components through the outer pipes with screws and secure the
entire flue system using the wall straps
supplied.
6. Connect the condensate tube to the heater once it has been installed. Connection points will
differ between the Arriva and the Evolve. For the Arriva refer to p.24. For the Evolve refer p.25.
DO NOT remove cap
Remember to consider how the wall straps will be secured to the frame—additional packing will be
required depending on where the wall straps are positioned.
IMPORTANT
Vertical in-wall flueing
The vertical in-wall vertical flue installation is installed against an internal wall
within a false fireplace or other suitable cavity, and is run vertically upwards to a
termination point. When considering the location of the fire ensure the flue path in
the roof space is free from obstructions such as studs, wiring, joists etc.
