Total flue length can be
up to 6.5 metres long!
Follow steps 1 through 5 from the chapter "Heater Installation" in the "Rinnai ASPIRATION Operation / Installation
Manual" supplied with the heater.
The Direct flue kit 750 (ASPDFK) is suitable for walls up to 385mm thick. For wall thicknesses greater than 385mm
Co-ax Pipe(s) (ESPIPE900) can be fastened onto ASPDFK 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 6.
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 ASPDFK. Fit additional lengths of ESPIPE900 as required.
The joints between ASPDFK and ESPIPE900 and any additional ESPIPE900 lengths MUST BE
secured by a pop rivet or screw through the outer co-ax pipes to prevent accidental or erroneous
CAUTION
dislodgement. ASPDFK and ESPIPE900 DO NOT require cutting to be joined.
Cutting of components is not required for the purposes of joining and ESPIPE900 to ASPDFK or
other ESPIPE900.
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 ~ ASPDFK & ESPIPE900" on
page 18.
5. Move the heater into place and make the heater exhaust and combustion air hose connections in accordance
with the section "CONNECTING HEATER EXHAUST & AIR SUPPLY" on page 20.
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. Follow steps 6 through 11 from the chapter "Heater Installation" in the "Rinnai ASPIRATION Operation /
Installation Manual" supplied with the heater and complete the installation and commissioning of the heater in
accordance with these.
