COMMISSIONING
Filling the system for the first time
After connecting the central heating cooker, fill the system as follows:
Check tightness of all piping, the expansion vessel, and the circulation pump;
Open
“manual air release valve”
of the central heating cooker, located on its left side
(see fig. on page
10)
;
Open the
“boiler body and system load cock”
(see fig. on page 8)
to load the system. Act very slowly to
allow any air to escape from the central heating cooker through the
“manual air release valve”
;
Optimum working pressure is 1.2 bar;
If necessary, very slowly loosen the pump vent plug draining the fluid for a few seconds;
Vent all radiators and any other deaeration system to ensure that there are no air bubbles.
After installation, check the tightness of all hydraulic joints.
When installation has been completed, it is advised, for the first days of operation, to check the tightness of all
hydraulic joints.
The central heating cooker system can be emptied
through the “
boiler body and system drain cock”
located
i
nside the “
hydraulic compartment”
below the cooking oven
(see fig. on page 8)
.
During periods of intense cold it is appropriate that the heating system remains in operation. In
the case of a prolonged absence, antifreeze must be added to the heating water, or the system
be completely emptied.
In a system subject to being emptied frequently, it is essential that filling is performed with water suitably
treated to remove hardness which can give rise to scaling.
Pellet loading and mains connection
Perform the following steps:
Connect the central heating cooker to the electrical system using the cable supplied;
Put the
“main
ON/OFF
switch”
(see fig. on page 9)
located
inside the “
technical compartment”
of the
central heating cooker in position
“׀” (ON);
Fill the pellet tank; for the first start ever, to avoid wasting the time required for filling the entire screw
feed channel (this should be done every time the central heating cooker remains without pellets), we
recommend using what is mentioned in MENU 07
– INITIAL LOAD
(see page 46)
;
Turn on the central heating cooker using the relevant ignition key on the control panel. See the
instructions below.
It is recommended to use high quality pellets so as not to impair the central heating cooker
features
. Damage caused by poor pellets is not covered by the warranty.
Central heating cooker ignition cycle
Pressing button 4 (ON/OFF) for a few seconds allows starting the central heating cooker ignition cycle. After a
while, the display shows
“START”,
and the flue gas intake device and ignition resistance switch on. After 40
seconds, the central heating cooker moves to a pre-load phase (
“PELLET P-LOAD”)
useful to quickly fill the
brazier with pellet. The central heating cooker goes into
“FLAME STAND-BY”
after the pre-load phase.
When the flame is lit, the display shows the message
“FIRE”
.
This step is used to allow the fire to spread
evenly across the brazier. After these steps, the central heating cooker enters work mode at the pre-set
output.
In case of misfire, the central heating cooker goes into
“NO IGNIT-”
alarm.
The alarm may also occur if the brazier is dirty; in this case, clean the brazier and restart the central
heating cooker.
