BOILER TRANSPORT AND INSTALLATION.
7.1.
TRANSPORT AND STORAGE.
Boilers are delivered on a pallet, foil-wrapped and are fully
assembled. It is recommended to transport the boiler, in such packing
condition, as close as the possible target location for installation, what will
minimize the possibility of damage of the boiler enclosure.
All remaining parts of the packing should be removed in such a way
that it will not pose any hazard for people and animals.
Fittings, equipment, manuals and warranty cards are located in the
furnace chamber, packed and protected against damage.
The components are to be installed by the user according to the
enclosed manuals.
Appropriate lifts are to be used for lifting and lowering the boiler. For
transport, the boiler is to be secured against moving and tilting on a
vehicle's platform by means of belts, wedges and wooden blocks.
7.2.
BOILER ROOM REQUIREMENTS.
Conditions, which should be fulfilled by the boiler room where the
fuel-fired boiler will be installed, depending on the regulations currently in
force in the country of destination.
In Poland, these conditions are regulated by the Regulation of the
Minister of Infrastructure of 12 March 2009 on technical conditions which
should be fulfilled by buildings and their location. The revised regulation is
valid from 8 July 2009 /Journal of Laws No. 56/2009 item 461/ and quotes
the text of the standard
PN-B/02411:1987 Heat Engineering. Built-in
boiler rooms fired with solid fuel. Requirements.
In accordance with these regulations the room, where the boiler in
installed, cannot be intended for temporary and permanent stay of
people. This should be a separated technical room with a height not
smaller than 2.2 m in case of new buildings. In the case of the already
existing buildings, the allowable height is equal to at least 1.9 m.
Hint!
The boiler is to be transported in a vertical position!
The boiler is to be stored in a non-heated room, under a roof and
with efficient ventilation.
Prior to installation, it is to be determined if all parts have been
delivered and if they are in good technical condition. Installation of
additional elements has been described on pp. 37.-38.
Fuel
should be stored in the separated technical room near the boiler.
The floor in the room, where the boiler is located should be made of non-
flammable materials. In the case of floors made of flammable materials, it
should be covered with a steel sheet of thickness at least 0.7 mm to the
distance minimum of 0.5 m of boiler edge.
Pressure ventilation
of boiler-room fired with solid fuels, of installed
thermal power
up to 25 kW
should be executed as non-closeable
opening of area at least 200 cm
2
. In case of
exhaust ventilation
- the
boiler’s room to
25 kW
should have an exhaust duct of cross-section not
smaller than 14x14 cm.

The boiler room should be located, if possible, centrally in relation to
heated rooms; the boiler should be located as close to the chimney as
possible. The boiler room door should open outward and are to be made
of non-flammable materials.
