2. INSTALLATION

2.1 General Instructions

This device must only be used for the purpose for which it is specially designed. This unit
is designed to heat water to a temperature below boiling point at atmospheric pressure
and must be connected to a heating system and/or a water supply system for domestic
use, compatible with its performance, characteristics and its heating capacity. Any other
use is considered improper.
THE BOILER MUST ONLY BE INSTALLED BY QUALIFIED PERSONNEL, IN ACCORDANCE WITH ALL
THE INSTRUCTIONS GIVEN IN THIS TECHNICAL MANUAL, THE PROVISIONS OF CURRENT LAW,
ANY LOCAL REGULATIONS AND THE RULES OF PROPER WORKMANSHIP.
Incorrect installation can cause damage or physical injury for which the manufacturer declines
any responsibility.

2.2 Place of installation

This unit is an "open chamber" type and can only be installed and operated in permanently ventilated
rooms. An insuffi cient fl ow of combustion air to the boiler will affect its normal operation and fume
evacuation. Also, the fumes forming under these conditions (oxides) are extremely harmful to health
if dispersed in the domestic environment.
Therefore the place of installation must be free of dust, fl ammable materials or objects or corrosive
gases. The room must be dry and not subject to freezing.
When positioning the boiler, leave suffi cient space around it for normal maintenance activities.

2.3 Plumbing connections

The heating capacity of the unit should be previously established by calculating the building's heat
requirement according to current regulations. For good operation and long life of the boiler, the
plumbing system must be well proportioned and always complete with all those accessories that
guarantee regular operation and running.
If the delivery and return pipes follow a path where air pockets could form in certain places, it is
advisable to install vent valves at these points. Also, install a discharge device at the lowest point in
the system to allow its complete emptying.
If the boiler is installed at a lower level than the system, it is advisable to provide a fl ow-stop valve to
prevent the natural circulation of system water.
The temperature drop between the delivery manifold and the return to the boiler should not
exceed 20° C.
Do not use the water system pipes to earth electrical appliances.
Before installation, carefully wash all the pipes of the system to remove residues or impurities that
could affect the unit's good working.
Make the connections to the corresponding connections as shown in Fig. 5.
