Flexiheat FHSPN 35, Instruction Manual

Page: 2 / 8

1. General information
The Original Instruction Manual constitutes an
integral and material part of the product, and is to be
transferred to the user with the transfer of
ownership. It needs to be studied thoroughly and
retained for future reference, as all remarks included
in it provide important hints on safety during
installation, use and maintenance of the appliance.
The heating unit needs to be assembled and
installed with adherence to the standards in force in
the country of operation, according to indications of
the manufacturer, and operated by trained
professionals. Improper device installation might be
the cause of injury to people and animals and of
material damage, for which the manufacturer is not
liable.
The air heating unit may be used exclusively for the
purpose for which it was clearly designed. Any other
use shall be considered improper, and,
consequentially, hazardous.
In case of errors during installation, use or
maintenance that were caused by negligence in
terms of the law in force, of provisions in force or the
Original Instruction Manual (or any different manual
supplied by the manufacturer), the manufacturer is
not liable for any contract or other responsibility for
the arising damages, and the equipment warranty
becomes void.
The choice of heating units for heating buildings is
conducted based on a building thermal heat balance
sheet, with particular consideration of losses
stemming from the transfer of heat to buildings.
2. Foreseen use of the heating unit
The NPS series heating units are foreseen for
heating air in small to medium-sized rooms, in
buildings without a water-based central heating
system.
Thermal heat is generated as a result of combustion,
and the thermal energy is transferred through the
combustion chamber walls and the heat exchanger.
The air heaters are devices ideally suited for:

industrial halls, workshops

warehouses, shops, megastores,
additional burner - pellets) directly from the heat
exchanger tube to the outside environment,
without any intermediate liquid. During
combustion, smoke and other gases are
generated, which are ventilated by the chimney
line.
NOTE!
Due to the specifics of operation of the solid
fuel-fired air heater, operation supervision in
the form of operation parameter control is
necessary.

Thermal heat is generated as a result of combustion
in the combustion chamber, which is equipped with a
cast iron grid. The thermal energy is transferred from
the combustion gases to the ambient fresh air by
means of natural and forced convection.
The air and combustion gases are passed through
different ducts, which are welded and properly
insulated. The emerging combustion gases, after
cooling, are led out through a duct that must be
connected to a chimney or gas duct. The chimney or
gas duct diameter must be sufficiently large to
guarantee effective combustion gas removal. The air
used in the combustion process is taken directly
from the room or building being heated. For this
reason, it is of paramount importance to provide
appropriate ventilation for the heated room or
building that will guarantee the provision of an
appropriate volume of fresh air. The ash emerging in
the combustion process falls to the ash tray, from
which it can be removed without difficulty. The
heated air is distributed around the room through a
rotating blower, which is mounted in the top area of
the air heater.
The electric switch box with thermostat is
responsible for the assurance of electric energy to
the heater fan. When the heater outer casing
reaches the set temperature (35 °C), the fan is
switched on and warm air is distributed around the
room, in which the heater was installed.
