INSTALLATION
INFORMATION
STARTING AND STOPPING
Start:
The first start-up operation must be performed by qualified personnel, after making sure that the
components of the plant have been installed properly and that all the safety devices have been
adjusted correctly.
The first start-up consists of the following operations:
▪
close the room thermostat contact: the burner will start the operating cycle and, after the pre-
washing cycle, the flame will be ignited
▪
check that the fan starts about 1 minute after the flame is ignited
▪
check the combustion parameters
▪
wait for the generator to reach full speed (~20 min.) and make sure that the LIMIT thermostat
does not intervene
▪
open the room thermostat contact and make sure that the burner stops
▪
close the room thermostat contact again and perform a new burner ignition cycle
▪
close the fuel shut-off valve and make sure the burner stops
During the first start-up cycle, the burner may stop due to the lack of fuel supply. In this case, wait
at least 30 seconds and, after unblocking the burner by pressing the dedicated button, repeat the
operation.
During the first hours of operation, fumes and odours may form due to the heating of paints and
seals. It is a normal phenomenon that disappears after a few hours of operation.
It is recommended to ventilate the room.
Stop:
To stop the hot air generator, USE ONLY THE ROOM THERMOSTAT, by setting it to the minimum
temperature or by opening the contact of the switch itself (if present) or on STOP.
Wait for the fan to stop (~ 4 min.) and then, if necessary, turn the power off by acting on the main
switch.
Never stop the appliance by cutting off the electrical power, as the thermal energy stored in
the heat exchanger may cause dangerous overheating of the same, with possible damage
to the air heater. Moreover the LIMIT thermostat could be triggered and it might be
necessary to release it manually.
