5 Boiler installation
This section details how to install your boiler correctly. This involves the
following steps:
• Vent connection
• Heating circuit connection
• Electrical connections
• Connecting the fuel supply
5.1 Preparing for installation
▶ Unpack all cartons and boxes.
▶ Using the included packing list, check to be sure that you have all the
included parts.
Route the gas connection towards the left
If the gas connection needs to be on the left:
▶ Loosen the unions on the gas supply pipe completely.
▶ Reattach and seal the gas supply pipe after rotating it 180 °.
▶ Carry out leak test.
5.2 Connecting the heating system
This section explains how the boiler is connected to the heating system.

Every boiler is carefully inspected and tested before it
leaves the factory. However, if you discover any damage
or missing parts, please inform the supplier
immediately. Before disposing of packing material,
make sure that no parts are still in it.
The gas supply pipe is designed for a gas connection on
the right side.
NOTICE: Risk of boiler damage due to moisture!
▶ Protect the individual components of the control
system and the ignition system from damp (dripping
water, water spray, rain) during installation,
operation and servicing (e.g. pump replacement,
programmer replacement, etc.
NOTICE: Risk of system damage due to overheating as a
result of lack of water!
▶ Make sure that if the boiler is located above the level
of the heating system, it is fitted with a low water
indicator.
▶ The low water indicator must be installed when the
boiler is installed (

Fig. 8).
NOTICE: Risk of system damage due to high
temperature variations in the heating system!
▶ If the boiler is operated in conjunction with an air
conditioning system, it is essential to ensure that the
pipes for the refrigerant fluid are connected in
parallel with the boiler system by means of suitable
valves to prevent the refrigerant from entering the
boiler. This prevents refrigerant fluid from entering
the boiler.
▶ If the boiler piping is connected to the heating coils of
a hot-air heating system, these may be exposed to
the circulation of cool air. In this case, the boiler
piping must be equipped with a flow-control valve or
some other automatic system for preventing the
boiler water from circulating by gravity during the
cooling cycle.
NOTICE: Risk of system damage due to leaking
connections!
▶ Connect pipes without stress to the boiler
connections.
