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. ASPDFK can be cut to length to suit wall
thicknesses less than 385mm thick. For wall thicknesses greater than 385mm Co-ax Pipe(s) (ESPIPE900) can be
fastened onto ASPDFK to extend the flue length. Refer to the section "CREATING A "DIRECT EXTENDED" FLUE
INSTALLATION" on page 9 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" 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. Slide the internal wall plate over the terminal end of the ASPDFK pipe until it is nested on the raised ring of the
flue transition.
3. Pass the ASPDFK 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 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. 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.
