Connection To The Hydraulic System - Ferroli Econcept 50 A Installation And Operating Instructions Manual

2.3 Connection to the hydraulic system

Make the connections to the corresponding couplings, according to the positions indicated in Fig. 3.
The discharge of the safety valve must be
connected to a funnel or collection pipe, to
discarge against a wall approx 300mm from
ground level.
Make the connections to the boiler so as its
internal pipes are not subject to stress.
Note: Caution must be taken to ensure the
discarge pipe cannot cause damage to
persons en property in the event of discharge.
The appliance is not supplied with an
expansion vessel, and therefore such
device must be connected by the
installer. Please note that the
pressure in the system, when cold,
must be between 0.5 and 1 bar.
Water treatment
If water treatment is used Ferroli Limited
recommend only the use of Fernox or Sentinel water treatment products, which must be used in accordance
with the manufacturers instructions. For further information contact:

Note:
• If the boiler is installed in an existing system any unsuitable additives must be removed by thorough
cleasing. All systems should be cleansed according to B.S. 7593.
• In hard water areas treatment to prevent lime scale may be necessary.
• It is important that the correct concentration of the water treatment product is maintained in
accordance with the manufacturers instructions.
Water System
Note The boiler is designed for sealed systems only and must NOT be used on open vented systems.
Central Heating
Detailed recommendations are given in BS6798, BS5449, BS6700 and CP342 Part 2. Pipework not forming
part of the useful heating surface should be insulated to prevent any heat losses or possible freezing (i.e. in
roof spaces or ventilated underfloor spaces). Drain taps should be positioned at the lowest point of the
system in accessible locations to permit the whole system to be drained down. The drain taps should be in
accordance with BS2879. Copper tubing to BS2871, Part 1 is recommended for water carrying pipework.
Pipework in horizontal runs should have a gradient where possible to facilitate the removal of air. Ensure that
the boiler heat exchanger is not a natural point for air collection.
