CHECKS
To ensure the proper working of the equipment it is necessary certain basic parameters must be checked. Switch the
equipment on and carry out the following
:
Check that the fan assembly starts up about 1 minute
after the burner runs.
When the generator is up to temperature and working normally (after about 20 minutes of continuous working), carry
out
the following operations
:
Check there are no leaks of combustible materials
.
Check the fuel pressure, using the meter (where
possible)
.
Check that the fumes temperature is that given in the
paragraph TECHNICAL DATA, with a tolerance of +/- 10°C.
Check the setting of the dual thermostat is that indicated in the chapter TECHNICAL DATA.
Check the graduated reading on the dual thermostat indicates 50-60°C and that the LIMIT function is not triggered.
Check that the thermal jump corresponds to that indicated in the chapter TECHNICAL DATA, with tolerance of
±5°C.
Turn the dual thermostat’s dial manually to simulate the
intervention of the LIMIT thermostat and check that the
burner is in fact switched off
.
Open the room thermostat’s contact and check that it
acts only on the burner and does not also cause the fan
assembly to stop.
Check the motor absorption does not exceed that indicated on the plate
.
Check the thermal safety relay is set at the motor absorption value.
Check that the fan runs 4 minutes longer after the turn off of the burner, before to stop.
Check that the intervention temperature of the safety fan is 15-20 °C over the air temperature close to the sensor of
the safety fan.
It is compulsory to check that no condensation will appare into the heat exchanger durino the running. Fot this
ckeck, after ½ Hour of running turn the burner off, and check both through the chimney connection and the
smokes pipes the absence of humidity into the smokes collector and exhausts pipes.
CONTROLS
HEATING-STOP-VENTILATION SWITCH
This is located on the equipment’s electrical panel and its function is select the working cycle:
When set at the ‘heating’ symbol it programs the equipment so that the fan and burner function automatically
according to the demands for heat
.
When set at ‘fan’ it controls the equipment excluding the
burner. Only the fan is active providing summer ventilation
.
When set at ‘stop’ it stops the hot air generator. The fan works for a certain time to use up the heat accumulated in
the heat exchanger
.
ROOM THERMOSTAT
To be installed about 1.5 m above ground and in an area
sheltered from hot or cold air currents. It controls the switching
on and off of the equipment to maintain the temperature at the set level. It must be requested as an accessory
additional
to the standard delivery
.
BURNER RESET BUTTON
Located on the burner itself, its function is to reset the burner
when it gets locked off
.
LIMIT THERMOSTAT RESET BUTTON
A red button on the FAN-LIMIT dual thermostat with the function of resetting the burner after a overheating lock
.
FAN MOTOR THERMICAL PROTECTION RESET BUTTON
Located into the control box, on the thermic relais block, needs to restart the fan functioning after a block for
malfunctioning or exceeding electrical absorbance by the fan motor.
WARNING!
Before any resetting it is essential to find and remove the
cause of the safety system being triggered. If in any doubt
call
the nearest authorised technical assistance centre which
will give you any assistance you require
