Rinnai Australia 4 ES Flue Installation Manual
REGULATIONS, CLEARANCES & GENERAL INFORMATION
The heater and the flue system shall be installed in accordance with the following:
These components MUST be installed, serviced and removed by an Authorised Person! ONLY the Rinnai flue
system components specified in this manual MUST be used. Componenents NOT specified in this manual,
whether manufactured by Rinnai or otherwise, are NOT compatible and MUST NOT be used!
Rinnai Energysaver space heater when correctly installed with Rinnai approved flue components are room-sealed
appliances and no internal ventilation is required. The Rinnai Energysaver space heater is fan-assisted. Therefore
the fan assisted flue clearance dimensions from AS/NZS 5601 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 National Helpline (number on the back page).
• Manufacturer’s Installation Instructions • Current AS/NZS 3000, AS/NZS 3500 & AS 5601
• Local Regulations and Municipal Building Codes • Any other relevant Statutory Regulation
Before commencing an installation, read the installation sections of the ‘Customer and
Installation Manual’ supplied with the heater.
Note that AS/NZS 5601 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may have since been superseded.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 AS/NZS 5601 are met.

FLUE TRANSITION CONNECTIONS
Flue exhaust connection to heater. Combustion air inlet connection to heater (Right hand ~ Small connection
for models 308, 309, 556, 557, 559, 561 heaters. Left hand ~ Large connection for model 1004 & 1005 heaters).
Rubber combustion air inlet cap (when fitted) 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 help ensure a good seal and to ease assembly, a small tub of silicone grease is provided with the Direct Flue
Kit (ESDFK) and the In-Wall Transition Kit (ESKIT03). 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.

Note 1. When cutting the flue transition for joining to other components the minimum total length is NOT to be less than 300mm!
Note 2. A Condensate trap MUST be used at this point.
Note 3. Use of a flue transition fitted with a sideways flue termal extension, will count as one of the THREE (3) allowed bends of a flue run.
Note 4. Where stipulated a Minimum 2° fall is required to ensure correct drainage of condensation formed in the discharge flue.

WALL PENETRATIONS
It is CRITICAL that any wall penetrations are located correctly.
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 AS/NZS 5601.
Figure 6.2 from AS/NZS 5601 and additional information is shown on page 4.
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.
1. Select the desired location i for the Energysaver Heater.
2. Find the vertical centre line of the appliance ii and mark this
location on the wall.
3. Using Measurements A & B from Table 1, mark off the arc centre
iii on the wall.
The arc centre iii corresponds to the pivot point centre
of the telescopic flue elbow on the heater.
The RHFE-308 and RHFE-309 have a fixed length non-
telescopic flue elbow. Hence accurate marking of the
penetration arc and associated area are therefore
especially critical.
4. From the arc axis iii use the measurements C, D & E from Table
1. to draw an arc on the wall.
The lower end point of the arc iv will be the lower limit of the
minimum horizontal and vertical centre of penetration G.
The upper end point of the arc v will the be the upper limit of the
minimum horizontal and vertical centre of penetration G.
5. From the arc axis iii use the measurements F, D & E from Table
1. to draw an arc on the wall.
The lower end point of the arc vi will be the lower limit of the
maximum horizontal and vertical centre of penetration G.
The upper end point of the arc vii will be the upper limit of the
maximum horizontal and vertical centre of penetration G.
Due to the fixed length non-telescopic flue elbow of
the RHFE-308 and RHFE-309 model heaters
measurements C & F are the same for these models
only.
6. The penetration may be made anywhere within the confines of the
shaded minimum and maximum areas viii defined by the two
arcs.
