The Direct flue kit (ESDFK) is suitable for walls up to 385mm thick. ESDFK can be cut to length to suit wall
thicknesses less than 385mm thick. For wall thicknesses greater than 385mm Co-Axial Pipe(s) (ESPIPE900) can
be fastened onto ESDFK to extend the flue length. Refer to the section "CREATING A "DIRECT EXTENDED"
FLUE INSTALLATION" on page 12 for details.
Steps for creating a DIRECT flue installation are as follows:

1. Create the wall penetration(s) in accordance with the section "WALL PENETRATIONS" refer to page 8.
The minimum diameter required for wall the penetration for a DIRECT flue installation is 80mm to non
combustible surfaces such as brick and 100mm to combustible surfaces such as plaster.
Allow for a continuous 2° fall from the heater connection point to the wall terminal.
2. Slide the internal wall plate over the terminal end of the ESDFK pipe until it is nested on the raised ring of the
flue transition.
3. Pass the ESDFK through the internal wall penetration until the internal wall plate is flush with the wall.
4. Create the wall terminal in accordance with "ASSEMBLING WALL TERMINAL ~ ESDFK & ESPIPE900" refer
to page 20.
5. Make the heater exhaust and combustion air hose connections in accordance with the section "CONNECTING
HEATER EXHAUST & AIR SUPPLY" refer to page 25.
Air hose and heater exhaust connections at the Energysaver heater MUST be made and checked
in accordance with these instructions. Improper connections may result in dangerous situations,
CAUTION
for example, the dispersion of combustion products in the space being heated.
6. Install the correct back cover kit and fasten the heater and back cover kit to the internal wall surface.
7. Commission the heater in accordance with the manufacturer instructions supplied with the heater.
