2.1. SCHEMATIC VIEW OF CIVIL WORK
VERSION "A": CONVECTION with external air intake
(clean air)
VERSION "B": CONVECTION with local air intake
(recirculation of the same air)
VERSION "B"
IMPORTANT! The ventilation grills of the cap have to
be placed so that they are not stopped.
The air that goes out of the top ventilation grills can
reach high temperatures, do not use materials that
do not resist to the heat in the zone of exit of the
grills. They have to be, in addition, metallic (never
use grills of wood or plastic).
Do not place objects near the top grills of ventila-
tion. The warm air that goes out of them can ruin
them.
The minimum recommended size of the grids is 400
cm² free passage of air, one at the bottom and one
at the top of the coating as shown in figure.
For further information on the correct installation of
the device, please see the Manual for the Profession-
al Installer.
VERSION "A"
2.2. INSTRUCTIONS FOR INSTALLING THE HEATER FIRE-
PLACE.
VERY IMPORTANT!
WE RECOMMEND
ALWAYS BE CARRIED OUT BY A PROFESSIONAL
HEATING SYSTEM EXPERT.
If the stove should be lit by accident when there is no
water in the system, immediately put out the fire so as
not to damage the boiler. In such a case NEVER FILL
THE SYSTEM WITH WATER WHEN THE FIRE HAS BEEN
LIT IN THE STOVE.
The appearance of water on the inside walls of the boil-
er, especially after lighting up for the first few times,
may be due to condensation. This will tend to disap-
pear with use.
The H02/22 SE heater fireplace has been designed for
intermittent combustion.
There are several
"Professional Installer's Manual for Heating Applianc-
es" to be taken into account for the heating installa-
tion.
NOTE TO INSTALLER:
Before connecting the fireplace to the water heater
check that the latter is sealed at a pressure of 3 bar.
Never connect the device directly to the circuit.
Thermostatic safety.
The installation of a 95-97ºC thermal discharge valve
(in the flow) together with an automatic filling valve
(in the return) is required. This will prevent excessive
rise in temperature inside the pan evacuating hot wa-
ter to a drain. The probe that activates the discharge
valve is located in the ¾'' sleeve (Fig. 3).
