Follow steps 1 through 5 from the chapter "Heater Installation" in the "Rinnai ASPIRATION Operation / Installation
Manual" supplied with the heater.
The Down & Out flue option allows for a Flue Adaption Kit 750 (ASPKIT03) to face downwards and the flue to be
run vertically though a hole in the floor, and then horizontally to a suitable location outside. When considering the
location of the heater due care must be taken to ensure that the flue path under the floor is free of obstructions
such as studs, noggins, joists, braces, and electricals etc.
Flue must not terminate under a building.
Flue terminal is only available in the horizontal format.
CAUTION
Steps for creating a Down & Out flue installation are as follows:

1. Assemble the Flue Adaption Kit 750 (ASPKIT03) joining the flue transition and the condensate components
together in accordance with "COMPONENT ASSEMBLY & CONNECTION ~ ESCONDK" on page 19.
The joints between the flue transition, condensate trap and ESPIPE900 MUST BE secured by a
pop rivet or screw through the outer co-ax pipes to prevent accidental or erroneous dislodgement.
CAUTION
The entire assembly is to be clipped using the stand off clips supplied or other suitable method.
ASPKIT03 components DO NOT require cutting to be joined.
2. Use the section "WALL PENETRATIONS" on page 6 to determine the vertical and horizontal location of the
heater's flue exhaust outlet and mount the assembled ASPKIT03 components in this location in an downwards
vertical manner.
