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.

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.

CREATING AN “EXTERNAL WALL” FLUE INSTALLATION
The creation of the horizontal section of flue installation is the same as creating a DIRECT or DIRECT EXTENDED
flue installations with the following exceptions:
The direction of horizontal fall of the flue pipe is reversed. For Wall External flue installations, a 2° fall is
required from the wall penetration towards the heater. This will ensure the small amount of condensation in the
short section between the heater and condensation trap will ‘burn off’ rapidly during normal operation.
An ESBEND rather than a mushroom flue terminal is fitted at the end of the horizontal flue run.
Steps for creating a External-Wall flue installation are as follows:
1. Create the wall penetration(s) in accordance with the section “WALL PENETRATIONS” refer to page 8.
The minimum diameter required for wall the penetration for a DIRECT flue installation is 80mm
noncombustible surfaces such as brick and 100mm to combustible surfaces such as plaster.
Allow for a continuous 2° fall towards the heater connection point from the external wall penetration.
2. Prepare the 'horizontal' section by following step 2 of “CREATING A “DIRECT” FLUE INSTALLATION” refer to
page 11 or step 2 of “CREATING A “DIRECT EXTENDED” FLUE INSTALLATION” refer to page 12 depending

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.
Activities for creating an External Wall installation:
a.- f. Refer to Direct & Direct Extended (as required).
g. Assemble Wall Plate.
h. Assemble & Fit Bend.
i. Fit Condensate Drain.
j. Cut, Fit & Secure Components. Seal Joints
(as required).
k. Create Vertical Penetrations (as required).
l. Fit & Fasten Roof Cowl or On-Wall Terminal.
z. Finalise Installation & Commissioning of Heater.

Joints between ESDFK, and ESPIPE900 MUST be secured by a pop rivet or screw through the
outer Co-Axial pipes to prevent accidental or erroneous dislodgement. Pipes are to be clipped
using the stand off clips supplied or other suitable method. ESDFK and ESPIPE900 DO NOT
require cutting to be joined.
Of special relevance to under floor installations 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.
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.

FLUE COMPONENT ASSEMBLY
CUTTING ~ ESDFK, ESPIPE900 & ESROOFCOWL
Cutting components to achieve a desired length
1. Measure and mark off the outer pipe at the desired length (AA).
2. Cut the outer pipe to the required length. Take care NOT to cut the inner pipe.
3. From the ‘new’ end of the outer pipe (cut in Step 2.), measure and mark off an additional 12mm on the inner
pipe (BB). Cut the inner pipe at this mark. Take care to keep the cut parallel with that of the outer pipe.
4. Ensure all burrs and swarf are removed from all cut ends.
Cutting components at a wall penetration
1. Measure and mark off the outer pipe at a point flush with the surface of the wall penetrated (CC) PLUS an
additional 50mm (DD).
2. Cut the outer pipe to the required length. Take care NOT to cut the inner pipe.
3. From the ‘new’ end of the outer pipe (cut in Step 2.), measure and mark off an additional 12mm on the inner
pipe (EE). Cut the inner pipe at this mark. Take care to keep the cut parallel with that of the outer pipe.
4. Ensure all burrs and swarf are removed from all cut ends.
COMPONENT ASSEMBLY & CONNECTION ~ ESPIPE900
Lubricate O-Rings with the supplied O-ring grease, then fit the female aluminium inner pipe end over the male
inner pipe ends of an adjoining component.
STOP! When terminating a flue run and installing the wall terminal, follow the instructions under
“ASSEMBLING WALL TERMINAL ~ ESDFK & ESPIPE900” on page 20 for pipe cutting procedures.
Cutting is not required for the purposes of joining ESDFK, ESPIPE900 & ESROOFCOWL together
Cutting of the last component in the flue assembly (the component furthest away from the heater)
may be required to achieve the required flue system length. Cutting is also required at a wall
penetration. Cutting for both purposes is described below:
The minimum length (ZZ) of ESDFK when measured from the back plate of the casting MUST
NOT be less than 300mm when joining to other components.
The minimum length (ZZ) of ESDFK when measured from the back plate of the casting MUST
NOT be less than 300mm when joining to other components.
Both the inner and outer pipes of all internal horizontal components MUST be secured with
rivets or screws. The joints of PVC outer pipes that are exposed to an outside environment MUST
be sealed with an appropriate PVC solvent.

FLUE COMPONENT ASSEMBLY
ASSEMBLING WALL TERMINAL ~ ESDFK & ESPIPE900
1. Fit the supplied external wall plate over the outer pipe of the flue protrusion.
As an installation aid the wall plate has a 2°offset. As such the orientation of the wall plate will set the
flue system with either a 2° fall or rise as required. Set the flue system with a 2° fall away from the heater by
aligning the arrow symbol so that it is upper most.
Once the external wall plate is in the correct position secure it to the wall using the three 22mm screws
into the holes provided. The wall plate is then secured to the outer pipe of the flue protrusion using the
two horizontal holes and the two 7mm screws provided.
2. Carefully cut through the outer and inner pipes of the flue protrusion as close to the external wall plate as
possible. Take care to avoid cutting the external wall plate and keep the cuts of both internal and external
pipes as parallel as possible. All burrs and swarf are to removed from all cut ends.
3. Align the arrows of the metal mushroom flue terminal and the wall plate to point in the same direction and
screw the terminal to the external wall plate using the 22mm screws into the holes provided.
ASSEMBLING AN ON-WALL TERMINAL ~ ESWTKIT, ESBEND & ESPIPE900
1. Measure off the required terminal length then mark off for cutting allow an additional 50mm for joining to
other components. Cut the outer pipe at this mark. Take care to NOT cut the inner pipe while cutting
the outer pipe.
2. From the end of the cut outer pipe measure off an additional 35mm on the inner pipe and mark off for cutting.
3. Ensure that burrs and swarf are removed from all cut ends. Attach the pipe spacer to the outer pipe and the
flue outlet grill to the inner pipe. When preparing an on wall terminal ensure a continuous 2° fall from
the flue termination point back towards the heater (condensate trap).
Flue MUST terminate in accordance with AS/NZS 5601 Figure 6.2. 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.
ONLY the direct flue kit (ESDFK) and the Co-Axial pipe (ESPIPE900) can be modified to create a
wall terminal.
The creation of an on wall terminal can only be achieved by using a combination of ESWTKIT,
ESBEND and ESPIPE900 flue components.
For the on wall terminal it is CRITICAL that the inner pipe components are secured with rivets
or screws and that the joints of PVC outer pipes are sealed with an appropriate PVC solvent.
