The Direct flue kit (ESDFK) is suitable for walls up to 385mm thick. For wall thicknesses greater than 385 mm
Co-Axial Pipe(s) (ESPIPE900) can be fastened onto ESDFK to extend the flue length.
Steps for creating a Direct Extended flue installation are as follows:

1. Create the wall penetration(s) in accordance with the section "WALL PENETRATIONS" on page 8.
The minimum diameter required for wall the penetration for a DIRECT flue installation is 80mm to
noncombustible 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. Join ESPIPE900 to ESDFK. Fit additional lengths of ESPIPE900 as required.
The joints between ESDFK and ESPIPE900 and any additional ESPIPE900 lengths MUST be
secured by a pop rivet or screw through the outer Co-Axial pipes to prevent accidental or
CAUTION erroneous dislodgement. ESDFK and ESPIPE900 DO NOT require cutting to be joined.
Cutting of components is not required for the purposes of joining and ESPIPE900 to ESDFK or
other ESPIPE900.
CAUTION
Slide the internal wall plate over the terminal end of the assembled flue pipe until it is nested on the raised ring
of the flue transition.
3. Pass the flue assembly 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 back cover kit and fasten the Energysaver heater and back cover kit to the internal wall surface.
7. Commission the heater in accordance with the manufacturer instructions supplied with the heater.
