INSTRUCTIONS PRIOR TO INSTALLATION
Ensure any packaging or transit protection has been removed from the appliance before installation.
The following notes and instructions are addressed to tters to allow them to carry out trouble-free installation. Instructions for
lighting and using the boiler are contained in the ‘Instructions for Users’ section. This appliance shall be installed only by authorised
persons and in accordance with the manufacturer's installation instructions, local gas tting regulations, municipal building codes,
electrical wiring regulations, local water supply regulations, AS/NZS 5601 - Gas Installations and any other statutory regulations.
Refer to AS/NZS 5601 for gas pipe size.
Additionally, bear in mind the following:
• When installing the unit in environments with temperatures lower than 0°C, take the necessary precautions to avoid the
formation of ice in the siphon and in the condensation drain.
• This boiler can be connected to any type of double- or single-pipe convector plate, radiator or thermoconvector. Design the
system sections as usual, though, bearing in mind the available ow-head at the plate, as shown in section 16.
• Do not leave any packaging (plastic bags, polystyrene, etc.) within the reach of children as they are a potential source of
danger.
• Initial lighting of the boiler must be carried out by an authorised Service Engineer, as indicated on the attached sheet.
Failure to observe the above will render the guarantee null and void.
ADDITIONAL PUMP WARNING
If an additional pump is used on the heating system, position it on the boiler return circuit. This will allow the correct operation of
the water pressure switch.
SOLAR WARNING
If the instantaneous (mixed) boiler is connected to a system with solar panels, the maximum temperature of the domestic hot water
entering the boiler must not exceed 60°C.
When supplied, the boiler is not tted with the following components: EXPANSION VESSEL - SYSTEM FILLING TAP -
HYDRAULIC SEPARATOR. These must be mounted by the installer.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical switch: do not use any phone in your building.
• Immediately call your gas supplier from a neighbour’s phone. Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the re department. Installation and service must be performed by a qualied
installer, service agency or the gas supplier.
Do not leave any packaging (plastic bags, polystyrene, etc.) within the reach of children as they are a potential source of danger.
Before Leaving: Check all connections for gas leaks with soap and water. DO NOT use a naked ame for detecting leaks. Ignite
burner to ensure correct operation of gas valve, burners and ignition. When satised with the performance of the boiler, please
instruct the user on the correct method of operation. In case the appliance fails to operate correctly after all checks have been
carried out, refer to the authorised service provider in your area.
9. INSTALLING THE BOILER
Take special care when lling the heating system. In particular, open any thermostat valves in the system, ensure the water
enters slowly in order to prevent the formation of air inside the primary circuit until operating pressure is reached. Lastly,
vent any radiators in the system. BAXI declines all liability for damage deriving from the presence of air bubbles in the
primary exchanger due to the incorrect or imprecise observance of the above.
The boiler must be installed on a at vertical wall which is capable of supporting the weight of the boiler. The location must take
account of the ueing method to be used and the position of the ue terminal, with regard to the requirements of AS5601.
Refer to AS5601 for gas pipe size details.
Refer to AS3688 for water pipe threaded fastening connections.
Refer to AS/NZS 3500.4 for "Plumbing and Drainage heated Water System".
The template outline is shown in annex "SECTION" C at the end of this manual.
After deciding the exact location of the boiler, x the template to the wall. Connect the system to the gas and water inlets present
on the lower bar of the template. Make sure the rear part of the boiler (back) is as parallel as possible to the wall (otherwise,
shim the lower part). Fit two G1" taps (ow and return) on the central heating circuit; these taps make it possible to carry out
important operations on the system without draining it completely. On the Italian market, the system must comply with Raccolta
R safety provisions (limit thermostat, safety pressure switch, fuel cut-off valve, etc..). Fit a hydraulic separator, sized according to
maximum boiler and system pressure, downline from the hydraulic connectors of the boiler. If you are either installing the boiler
on an existing system or replacing one, as well as the above, t a settling tank under the boiler on the system return line in order
to collect any deposits and scale circulating in the system after ushing. After xing the boiler to the template, connect the ue
and air ducts, supplied as accessories, as described in the following sections. Connect the siphon to a drain trap, making sure the
slope is continuous. Avoid horizontal stretches. The boiler is electronically tted out for connection to an external storage boiler.
Do not lift the boiler exerting pressure on the plastic parts like the siphon and the ue turret.
