DESCRIPTION OF THE HEATER
The FAST heater functions by using the thermal
energy produced through combustion. The thermal exchange occurs when the air flow, generated by a centrifugal fan, passes on the surface

8
of the heat exchanger whithout the aid of any
intermedial fluid.
The combustion products, once completed the
thermal exchange, are ejected outside.
This system allows a noticeable reduction of costs on
installament and a reliable and economic use,
particularly ideal for all final users that require
intermittent or irregular heating.
This heater can also be used, in summer, as a
ventilator.
GENERAL MANUFACTURING NOTES:
The heater is composed of the following parts:
•The combustion chamber, of the “flame reversal”
type, is made of AISI 430 stainless steel,
resistent to high temperatures, with a low thermal
charge with different shapes or volumes
depending on the model.
•Tube nest heat exchanger that guarantees a
maximum thermal efficiency.
•Back smoke manifold with inspection door for an
easy access when cleaning pipes.
•Four way head air diffuser with revolving flaps
that can be completely shut for excluding air on
one side.
•External steel epossidic painted panels that can
be dismantled.
•Thermal anti radiant insulation of the surfaces
exposed to heat radiation of the exchanger.
•Hole set to be connected to a ducting system.
•Casing with an inspection door to protect the
burner and the tank.
•Centrifugal fan with two suction inlets,
noiseproof, high performance, single voltage
electrical motor directly connected to a
centrifugal fan.
•Large capacity oil tank equipped with filling hose,
filter and connection fittings to the burner.
•Oil suction burner equipped with electrical control
for fully automatic use.
ELECTRIC PARTS:
•Liquid expansion FAN” thermostat (35°C) which
stats the fan 60 seconds after ignition of the
burner and stops it 4 minutes after the burner
stops. This avoids the cold air exiting when
switched on and expels the heat accumulated in
the heat exchanger once the unit has been
turned off.
•“LIMIT” thermostat (100°C), with a reset manual
switch, that stops the burner when the air is
overheated. When the “LIMIT” switch is
activated, reset only after checking and
eliminating the causes for which it was activated.
•Room thermostat (0-40°C) for automatic
regulation of the room temperature through a
sensor positioned on the air inlet and an
adjusting knob positioned on the central panel.
•Green light indicating electrical voltage.
•Yellow light indicating the “LIMIT” thermostat is
working.
•Red light indicating that the burners electronic
device has stopped.
•3 position switch to set heating, ventilation or to
stop.
IDENTIFICATION
The FAST heater can be identified through a
Technical Data plate where all technical specifications are marked, it is positioned directly inside the burner cabinet.

COMMANDS
ROOM THERMOSTAT
It is installed on the unit, its function is to
automatically switch on and switch off the heater in
order to maintain the temperature that has been
selected.
HEATING / STOP / FAN SWITCH
It is positioned on the electrical control board and it
selects the different cycles:
•When set on “heating” the unit automatically
switches on both fan and burner according to the
heat required.
•When set on “fan” the unit automatically switches
off the burner and the fan can be used to cool in
summer.
•When set on “stop” the unit automatically stops.
The fan continues to function for a while to expel
the hot air that is inside the heat exchanger.
FUNCTIONING CYCLES
WORKING THE FAN
Follow these instructions to activate the fan:
•Connect the electricity to the unit
•Position the switch on the “fan” position
In this condition only the fan works so the air exiting
the heat is the same temperature of the air entering.
WORKING THE HEATER
Follow these instructions to activate the heater:
•Connect the electricity to the unit
•Set the thermostat at the temperature required
•Position the switch on “heating”
•The burner is electrically fed and once the pre-
purge has taken place the flame ignites
•One minute after the flame ignites the fan starts
working and hot air exits the unit
•Once the set temperature has been reached
according to the room thermostat the burner stops
working and 4 minutes later also the fan stops.
The whole cycle starts automatically every time that
the rooms temperature is under the temperature set
on the thermostat.
STARTING AND
STOPPING
STARTING
The heater must be started for the first time by
qualified personnel, who must check that the heater
has been correctly installed, the regulation works and
that the safety norms have been observed.

19
Starting the heater for the first time:
•Close the room thermostat contact: the burner
starts its cycle and following the pre-purge the
flame ignites
•Check that the fan starts one minute after
ignition
•Check combustion
•Wait for the heater to reach its steady-state
condition (~20 min.) and check that the LIMIT
thermostat is not functioning
•Open the room thermostat contact and check that
the burner has stopped
•Close the room thermostat and start a new ignition
cycle on the burner
•Close the fuel valve and check the burner is
blocked
•Check the fan stops automatically
ATTENTION
When starting for the first time it is possible that the
burner stops because fuel does not immediately flow
to the burner. If this occurs wait for at least 30
seconds, push the switch and start the same
operation again.
When ignited, during the first few hours, there could
be smoke due to paint or joints being heated. This is
normal and will stop after a few hours.
Alway make sure air ventilation is regular.
STOPPING
Stop the heater EXCLUSIVELY BY ACTING
DIRECTLY ON THE ROOM THERMOSTAT
CONTROLS
To control the heater is working correctly it is
necessary to carry out some basic tests:
•Check that the fan is working about 1 minute from
ignition of the burner.
When the heater is running regularly (after running for
about 20 seconds non-stop):
•Check there is no fuel leakeage.
•Check the correct fuel flow with a fuel-meter (if
possible).
•Check the setting coresponds to the indication in
the “TECHNICAL DATA” section.
•Check the temperature rise corrisponds to
information contained in the “TECHNICAL DATA”
section.
•Open the contact on the room thermostat and
check it works only on the burner and does not
simultaneously stop the fan.
•Check that the current intake value of the motor/s
is not higher than the value indicated on the data
plate.
•Check that the fan rotates for about 4 minutes
from when the burner stops working.
MAINTENANCE
We recommend, to work and conserve the heater
correctly, to clean regularly and carry out
maintenance. Any maintenance operation must be
made only by trained personnel.

20
Maintenance must only be done when the unit is cold
with the electrical and fuel connections switched off.
It is advisable to use protective gloves, and if any
equipment such as ladders etc. are used it is
important to work in safe conditions.
