2. Installation
2.1 General Instructions
BOILER INSTALLATION MUST ONLY BE PERFORMED BY QUALIFIED PERSONNEL, IN ACCORDANCE WITH
ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL MANUAL, THE PROVISIONS OF CURRENT LAW, THE PRE-
SCRIPTIONS OF NATIONAL AND LOCAL STANDARDS AND THE RULES OF PROPER WORKMANSHIP.
2.2 Place of installation
The combustion circuit is sealed with respect to the place of installation and therefore the unit can be installed in any
room. However, the place of installation must be sufficiently ventilated to prevent the creation of dangerous conditions
in case of even small gas leaks. This safety measure is required by EEC Directive no. 90/396 for all gas units, including
so-called sealed chamber types.
The unit is suitable for operation in a partially protected place in conformity with EN 297 pr A6, with minimum tempera-
ture -5°C. If equipped with the special antifreeze kit it can be used with minimum temperature as low as -15°C. It is ad-
visable to install the boiler under the slope of a roof, inside a balcony or in a sheltered recess.
Therefore the place of installation must be free of dust, flammable materials or objects and corrosive gases.
The boiler is arranged for wall mounting; by request a metal template is available for marking the drilling points on the
wall. The LEJ LINE plumbing connection kits also come with a paper template for marking the drilling points on the wall
in case the kits are used. The wall fixing must ensure a stable and effective support for the generator.
A
If the unit is enclosed in a cabinet or mounted alongside, a space must be provided for removing the casing
and for normal maintenance operations.
2.3 Plumbing connections
The heating capacity of the unit must be previously established by calculating the building's heat requirement according
to current regulations. The system must be provided with all the components for correct and regular operation. It is ad-
visable to install on-off valves between the boiler and heating system allowing the boiler to be isolated from the system
if necessary.
B
The safety valve outlet must be connected to a funnel or collection pipe to prevent water spurting onto the floor
in case of overpressure in the heating circuit. Otherwise, if the discharge valve cuts in and floods the room,
the boiler manufacturer cannot be held liable.
Do not use the water system pipes to earth electrical appliances.
Before installation, carefully wash all the pipes of the system to remove any residuals or impurities that could affect prop-
er operation of the unit.
Carry out the relevant connections according to the diagram in and thesec. 4.1 symbols given on the unit.
System water charcteristics
In the presence of water harder than 25° Fr (1°F = 10ppm CaCO
to avoid possible scaling in the boiler. The treatment must not in any case reduce the hardness to values below 15°F
(Decree 236/88 for uses of water intended for human consumption). Water treatment is indispensable in the case of
very large systems or with frequent replenishing of water in the system. If partial or total emptying of the system be-
comes necessary in these cases, it is advisable to refill it with treated water.
Antifreeze system, antifreeze fluids, additives and inhibitors
The boiler is equipped with an antifreeze system that turns on the boiler in heating mode when the system delivery water
temperature falls under 6°C. The device will not come on if the electricity and/or gas supply to the unit are cut off. If it
becomes necessary, it is permissible to use antifreeze fluid, additives and inhibitors only if the manufacturer of these
fluids or additives guarantees they are suitable for this use and cause no damage to the heat exchanger or other com-
ponents and/or materials of the boiler unit and system. It is prohibited to use generic antifreeze fluid, additives or inhib-
itors that are not expressly suited for use in heating systems and compatible with the materials of the boiler unit and
system.
