3. It is obligatory to place a closed expansion vessel on the installation.
The vessel's load pressure must be the same as the filling pressure.
The volume of the expansion vessel must be proportional to the
volume of water in the installation.
4. It is advisable to place a minimum thermostat in the installation that
will cut the circulator when the water from the tubes falls below
50ºC. This will avoid condensation when the hearth is lit.
5. It is advisable that all installation components (safety valve,
circulator, expansion vessel...) should be placed in the return system.
How to act in the event of overheating or fire in the chimney.
If you should detect any overheating of the hearth caused by:
Fan failure
Circulator failure
Thermostat failure
You should shut down the device in order to avoid damaging cast iron
parts.
Follow these recommendations:
x Do not introduce any more fuel.
x Open the door slightly to let more air in; this will cause the flames to
grow and consume the fuel more quickly but will also cool the chimney
and reduce draw which will also cool the device.
In the event of fire in the chimney, follow the same steps as indicated above.
Call the emergency services as soon as possible.
Lighting up the H-02/22
To light up the hearth, first lay a base of paper on the grate at the bottom.
Then place a layer of thin branches or pieces of wood. Before lighting the
paper, it is advisable to place some paper in the cast iron deflector,
accessing through the front door, and light it; this will heat up the chimney,
forcing our any cold air inside (especially on cold winter days), favouring
the draw and avoiding any smoke from leaking into the room.
Now you may light the paper and wooden base; leave the door slightly open
for about 20 minutes. Once the flame has stabilised, close the door and the
device may be regulated by means of the valve on the ash pan.
ATTENTION!! When the hearth is working, the metal parts may reach high
temperatures. Protect your hands with fireproof gloves if you have to touch
it.
