Rinnai Australia 2 ASP Flue Installation Manual
REGULATIONS, CLEARANCES & GENERAL INFORMATION
The heater and the flue system shall be installed in accordance with the following:
• The requirements of the current version of AS 5601 (Gas Installations)
Note that AS5601-2004 is referred to in this instruction and was current at the time of printing, but may have
since been superseded. It is the Installer’s responsibility to ensure that requirements of the current version of
AS5601 are met.
• Manufacturers installation instructions.
Before commencing an installation, read the installation sections of the ‘Customer and Installation Manual’
supplied with the heater.
• Local & Municipal building codes.
• Any other relevant Statutory Regulation.
• Rinnai Energysaver space heaters when correctly installed with Rinnai approved flue components are room-
sealed appliances and no internal ventilation is required.
• Rinnai Energysaver space heaters are fan-assisted. Therefore the fan assisted flue clearance dimensions from
AS5601 extract shown on this page must be used.
• The outer plastic section of the co-axial flue complies with temperature hazard requirements and can be
installed with zero clearance to combustible material.
• Vertical clearances when using a roof terminal (ESROOFCOWL) are shown in Fig.1.
If in doubt contact the Rinnai Australia Technical Advice Helpline (number on the back page).

FLUE TRANSITION CONNECTIONS
Flue exhaust connection to heater. Combustion air inlet connection to heater (Left hand ~ Large connection
for model REFE 750 heaters only the Right hand ~ Small connection not used). Rubber combustion air inlet
cap (when supplied) is designed to fit both the large and small combustion air inlet and MUST cover the air inlet
not in use. Combustion air inlet. Exhaust outlet.
LOCATION
LUBRICATING INNER PIPE COMPONENTS
The inner flue pipe joints are sealed with an “O” ring seal.
To ease assembly, a small plastic tub of silicone grease is provided with the Direct Flue Kit 750 (ASPDFK) and the
Flue Adaption Kit 750 (ASPKIT03). Use this silicone grease to lubricate the “O” ring on the inner pipes prior to
assembly.
This appliance is NOT suitable for inbuilt installations.
This appliance MUST NOT be installed where curtains or other combustible materials could come into contact with
it. In some cases curtains may need restraining.
Heat emanating from the front
of this appliance may over time
affect the appearance of some
materials used for flooring such
as carpet, vinyl, cork or timber.
This effect may be amplified if
the air in the room contains
cooking vapours or cigarette
smoke. To avoid this possibility,
it is recommended that a mat be
placed in front of the appliance,
extending at least 750mm in
front of it.
The flue terminal MUST BE positioned away from flammable materials.
In areas subject to heavy snowfall, keep snow clear of flue terminal at all times.
•DO NOT flue into natural
draught flues or fireplaces.
•DO NOT flue into other
rooms, roof spaces or into
under floor spaces.
•DO NOT Install the heater in
an unusually dusty area.
For other important information regarding the location of the heater refer to the instructions
supplied with the appliance.
Use ONLY the supplied silicone based “O Ring” seal lubricant.
DO NOT use petroleum based lubricants such as petroleum jelly. Petroleum jelly or similar
petroleum based lubricants will cause deterioration of the “O” ring seals.

WALL PENETRATIONS
It is critical that any wall penetrations are located correctly.
The enclosure dimensions specified are critical to the successful installation of this appliance
and MUST BE strictly adhered to.
Ensure there are no wall studs, noggins, wiring or other obstruction within the wall cavity where
the flue is proposed to penetrate.
Ensure the location of the flue terminal can comply with the requirements of AS5601. Figure 5.3
from AS5601-2004 and additional information is shown on page 2.
Especially relevant is the requirement to have a minimum of 300mm clearance between the flue
terminal and the finished ground level. It is not permissible to excavate a hole to obtain the
required 300mm clearance, unless there is sufficient drainage provision.
Ensure the penetration points are marked accurately as this is critical for successful appliance
installation.
The penetration for the flue pipe only needs to be made for ‘Direct’ and ‘Direct Extended’ flue
installations, where the flue terminal is located directly to the rear of the appliance.
If no flue pipe penetration is required the markings are still useful for indicating the correct
position of flue exhaust connection of ‘Sideways’, ‘External Wall’, ‘Internal Wall’ and ‘Under Floor’
flue applications.
When creating penetrations for flue system installations other than ‘Direct’ and ‘Direct
Extended’ the minimum diameter required for the wall penetration of PVC external pipes is 80mm.
On all ‘Sideways’ and ‘Under Floor’ flue applications, allow for a continuous 2° fall from the
heater connection point to the wall terminal.
1. Select the desired location ifor the Heater.
2. Find the vertical centre line of the appliance ii and mark this
location on the wall.
3. Mark off a point iii that is A 378mm to the left of the centre line
and B 580mm from the base.
4. Make a 100mm penetration iv at point iii.
The penetration iv MUST BE aligned accurately in the
horizontal plane, however the penetration can be plus or
minus 25mm in the vertical plane (see detail AA).

FLUE COMPONENT ASSEMBLY
CREATING A “DIRECT” FLUE INSTALLATION
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.
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.
Activities for creating a Direct flue installation:
a. Create Wall Penetration.
b. Locate Heater.
c. Connect Heater Exhaust.
d. Connect Combustion Air Hose.
e. Cut Components (As Required).
f. Assemble Wall Terminal.
z. Finalise Installation & Commissioning Of Heater.
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.
