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 INSTRUC-
TIONS 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
insufficient flow 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 the health if dispersed in the domestic
environment.
Therefore the place of installation must be free of dust, flammable materials or objects or corrosive gases. The
room must be dry and not subject to freezing.
When positioning the boiler, leave sufficient 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 flow-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. 2.
