The Direct flue kit (ESDFK) is suitable for walls up to 385mm thick. For wall thickness’s greater than 385mm
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 10.
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.
Join ESPIPE900 to ESDFK. Fit additional lengths of ESPIPE900 as required.
CAUTION
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
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.
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 "Component Assembly & Connection ~ ESROOFCOWL" on page
23.
5. Make the heater exhaust and combustion air hose connections in accordance with the section "Connecting
Heater Exhaust" on page 28.
CAUTION
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,
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.
