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 Installation place

This unit is an "open chamber" type and can only be installed and operated in permanently ventilated rooms in compli-
ance with Standard UNI-CIG 7129.
If provided with an antiwind grille, the unit is suitable for operation in a partially protected place in compliance with EN
297 pr A6, with min. temperature -5°C. If provided with the special antifreeze kit it can be used with min. temperature
as low as -15°C. It is advisable to install the boiler under the slope of a roof, inside a balcony or in a sheltered recess.
In any case, the place of installation must be free of dust, flammable materials or objects and corrosive gases.
The boiler is arranged for wall mounting and comes standard with a hooking bracket. The LEJ LINE water connection
kits also come with a paper template for marking the drilling points on the wall in case the kits are used. Fix the bracket
to the wall and hook the boiler onto it. The wall fixing must ensure 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 sec. 4.1 and the symbols given on the unit.
