personnel.

Prior to start-up, the user must check for any evident non-compliance with rules of use, safety and
protection .
5. INSTRUCTIONS FOR USE
5.1 Start-up
•
The heater is factory set for operation
without room thermostat.

WARNING: THE APPLIANCE MUST BE EARTHED
Correct Incorrect
•
Indirect fired heaters: connect the heater to a
chimney or to a exhaust duct. To get a proper
draught (at least 0,1 mbar) in the chimney the
exhaust gas path must rise. Avoid any elbows
and bends in the first part of the exhaust ducts
for at least 3 m. For operation of heater in closed
rooms without flue refer to the instructions for
installation (par. 4)
•
If a room (remote) thermostat is used, set
maximum temperature on it.
•
Turn switch to position “ON”
•
Set the desired temperature on room
thermostat.
5.2. Reset after lockout – Safety air pressure switch
•
The heater is equipped with a Reset pushbutton. When the heater locks out, the red lamp on the pushbutton
(fig. 1 n°2) lights up. In this case push the Reset button (see also the par. “Troubleshooting”) to restart the
heater.
•
The heater is also equipped with an air pressure switch that controls the airflow pressure and locks the
heater out in the event of unit overheating. If this occurs, detect and eliminate the cause of overheating before
using the heater again. Have the heater inspected by a qualified technician if required. See point above for
resetting.
