3 Regulations
Where no specific instruction is given, reference should be made to the
following standards:
• AS/NZS 5601 Gas Installations,
• AS 1596 LPG storage and handling,
• AS 4552 Gas fired water heaters for hot water supply and/or central
heating,
• AS/NZS 3000 Electrical Installations,
• AS1697 Installation and maintenance of steel pipe systems for gas,
• AS 4032 Water supply - valves for the control of hot water supply
temperatures,
• AS 3498 Authorization requirements for plumbing products - water
heaters and hot-water storage tanks.
• AS 1910 Water supply - float control valves for use in hot and cold
water, AS 3500 National plumbing and drainage code.
4 Flue gas routing
Before fitting the gas boiler and the flue system, check with the local
planning authority and flue gas inspector whether there are any
restrictions.
The surface temperature at the combustion air pipe is below 85 °C for
concentric pipes. No minimum clearances to flammable building
materials are therefore required. Local regulations may differ from this
information and may stipulate minimum clearances to flammable
building materials.
4.1 Approved flue accessories
The flue accessories form part of the CE approval for the appliance. For
this reason, only the provided original flue accessories must be installed.
• Flue accessories, concentric pipe Ø 60/100 mm
4.2 Installation instructions
Fan stage :1 (Reference to service function 2.b.d ( page 21).
▶ Before fitting the flue kits:
Apply a thin coating of solvent-free grease (e.g. Vaseline) to the joint
seals.
▶ When fitting the balanced flue, always push the pipe fully home into
the sockets.
5 Installation
5.1 Important notes
▶ Before installing the appliance, consult your gas supply utility and
your local flue gas inspector [where appropriate].
Fill and top-up water for the heating system
Unsuitable fill and top-up water in the heating system can result in the
heat exchanger scaling up and failing prematurely.
Open vented heating systems
▶ Open vented heating systems must be converted to sealed systems.
Gravity fed heating systems
▶ Connect the appliance to the existing pipework via a low loss header
with a dirt separator.
Galvanised radiators and pipes
To prevent gas formation:
▶ Do not use galvanised radiators or pipes.
If a room thermostat is used
▶ Do not fit a thermostatic radiator valve to the radiator in the primary
room.
Anti-freeze
The following anti-freeze fluids are permitted:
Corrosion inhibitor
The following corrosion inhibitors are permissible:
Sealants
In our experience, adding sealants to the heating water may result in
problems (deposits in the heating block). We therefore advise against
using them.
Water circulation noises
To prevent water circulation noises:
▶ Fit an overflow valve or, with 2-pipe heating systems, a 3-way valve to
the radiator furthest from the boiler.
CAUTION: Low efficiency and functional problems if an
incorrect fan stage is used!
DANGER: Risk of explosion!
▶ Turn off gas valve before working on gas-carrying
components.
▶ Check for leaks before working on gas-carrying
components.
Installation, power connection, connection on the gas
and flue gas side and commissioning must only be
carried out by a contractor approved for such work by
the local gas or power supply authority.
Not suitable for pool or spa pool application.
Hardness range Water treatment
soft ( 8.4 °dH) not required
medium (8.4 - 14 °dH) recommended
hard (14 °dH) required

For straightforward water treatment:
▶ Use the system approved by us.

Mono-lever taps and thermostatic mixer taps
All mono-lever taps and thermostatic mixer taps can be used.

To protect the appliance against excessive pressure:
▶ Fit a pressure regulator with a safety valve.
5.2 Checking the size of the expansion vessel
The following diagram provides you with a rough estimate of whether the
installed expansion vessel is sufficient or whether an additional
expansion vessel is required.
The characteristic curves shown are based on the following key data:
• 1% water volume in expansion vessel or 20% of nominal volume of
expansion vessel
• Differential operating pressure of the safety valve of 0.5 bar,
according to DIN 3320
• Pre-charge pressure of expansion vessels matches static head of the
system above the heat exchanger
• Maximum operating pressure of 3 bar
Fig. 6

▶ Pluming will occur at the terminal so terminal positions where this
could cause a nuisance should be avoided.
▶ The air supply and the flue gas exhaust must meet the applicable
general regulations. Please consult the instructions provided with the
flue terminal kits prior to installation.
▶ The boiler must be installed so that the terminal is exposed to the
external air.
▶ It is important that the position of the terminal allows the free passage
of air at all times.
▶ Minimum acceptable spacing from the openings are specified above,
for domestic situations in accordance with AS 5601.
Combustion air
In order to prevent corrosion, the combustion air must not contain any
corrosive substances.
Substances classed as corrosion-promoting include halogenated
hydrocarbons which contain chlorine and fluorine compounds. They
may be found in solvents, paints, adhesives, aerosol propellants and
household cleaners, for example..
Surface temperature
The maximum surface temperature of the appliance is below 85 °C. That
means that no special safety precautions are required with regard to
flammable building materials and fitted furniture. If regulations differ in
individual countries they must be observed.
5.4 Fitting the appliance
▶ Fix the mounting template supplied with the documents to the wall,
observing a lateral clearance of at least 100 mm ( page 5).
▶ Drill the holes for the screw hooks according to the mounting
template.
