8 INSTALLATION
The installation of the boilers must be performed according to the current local
standards
and in addition, instructions stated below;
 All installation, assembly and maintenance work must be carried out exclusively
by fully trained, professionally qualified personnel and must conform with this
manual and the local codes and requirements of the authority having jurisdiction, or
in the absence of such requirements, apply to the EEC directives and European
norms (EN).
 This boiler must be installed in accordance with the rules in force and only in a
well ventilated and frost free spaces. Top and bottom ventilation openings must be
according to local codes.
 Boilers must be fired by a compatible burner certified to EN 676 (gas firing) or EN
267 (oil firing) to comply with the boiler efficiency requirement (92/42/EEC) directive
and Appliances burning gaseous fuels (90/396/EEC) directive.
 This is a B
23
appliance so the flue gases must be connected to an adequate
draught chimney, without any flue gas leakage to the boiler room.
 Control of the heating system shall enable the specified designed indoor
temperatures to be achieved under the specified variation of internal loads and
external climate and, protect building and equipment against frost and moisture
damage when normal comfort temperature level is not required.
 Heating system shall be equipped with automatic and/or manual control devices
according to current EN 12828.
 It is essential that an appropriate pump is fitted in the circulation system which
must be kept in automatic operation at all the times when the boiler in use.
 It is essential that a shunt pump (anti condensate pump) and/or 3 way valve
systems shall be fitted to the system in order to keep the return line temperature
above the condensation values.
 The filling and make up water must be according to the specifications given in
this manual. Long term water treatment is essential to the economic operation and
life of both new and refurbished heating systems.
 Boilers should be installed on a non-combustible, smooth and level foundation
which is at least 150 mm high and according to these manual and local codes.
 Boilers must not be installed in areas where inflammable vapors and materials
are likely to e present. To avoid damage to the boilers, contamination of the
combustion air by high levels of dust or halogenated hydrocarbons (e.g. Solvents,
spray can propellants, cleaning agents, adhesives, etc.) must be avoided. The
humidity level must not be high in boiler rooms.
 The boiler room must not be used for other purposes and must not have an open
connection to the other closed living areas. Connection door must be air tight, fire
resistant and self closing.
 An emergency shut down switch must be placed in a proper place outside the
boiler room. This switch must cut off the fuel line and must be identified by a name
plate.
 If the system is running with a fuel heavier then air and the boiler room is under
ground level, then the firing system must have a flame control device and the
possible leakage from fuel lines must be ventilated to a safe place by ex-proof
mechanical means.
