on page 14 for details.
Steps for creating a Direct ue 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 ue 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
ue transition.
3. Pass the ESDFK through the internal wall penetration until the internal wall plate is ush 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.

Co-Axial Pipe(s) (ESPIPE900) can be fastened onto ESDFK to extend the ue length.
Steps for creating a Direct Extended ue 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 ue 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
ue 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 ue assembly through the internal wall penetration until the internal wall plate is ush with the wall.
4. Create the wall terminal in accordance with "Component Assembly & Connection ~ ESROOFCOWL" on page
23.

The creation of the horizontal section of ue installation is the same as creating a DIRECT or DIRECT EXTENDED
ue installations with the following exceptions:
The direction of horizontal fall of the ue pipe is reversed. For External Wall ue installations, a 2° fall is
required from the wall penetration towards the heater. This will ensure the small amount of condensation in
the short section between the heater and condensation trap will ‘burn o󰀨’ rapidly during normal operation.
For ue runs terminated in the horizontal, an ESWTKIT2 is used (in combination with ESBEND & ESPIPE900).
CAUTION
Sections of ue installation located outside require the following precautions:
ONLY use PVC cement between joints of the 'outer' PVC ue pipes to secure and seal these
joints against ingress of dust and water.
ONLY use non acidic silicone sealant between the joints of 'outer' PVC ue pipes and any
mating aluminium components (such as the condensate trap) to secure and seal these joints
against ingress of dust and water. Silicone containing acetic acid (vinegar) or other acids as the
curing agent may cause corrosion of aluminium components and MUST NOT be used.
Steps for creating a External-Wall ue 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 ue installation is 80mm to non
combustible surfaces such as brick and 100mm to combustible surfaces such as plaster.
Allow for a continuous 2° fall towards the heater connection point from the external wall penetration.
2. Slide the internal wall plate over the terminal end of the assembled ue pipe until it is nested on the raised
ring of the ue transition.
Prepare the 'horizontal' section by following step 2 of "Direct Flue Installation Method" on page 13 or from
step 2 of "Direct Extended Flue Installation Method" on page 14 depending on wall thickness (note that a
direct extended ue installation example is illustrated above).
3. Pass the ue assembly through the internal wall penetration until the internal wall plate is ush with the wall.
