PLUMBING SYSTEM CONNECTIONS
⚠
Plumbing must always be carried out by qualified personnel, able to carry out a state-of-the-art installation in compliance with
the laws in force in the country of installation, after having read the next chapter. Ravelli denies all liabilities for damages to
people or property arising from malfunctions due to failure to comply with this warning.
Installation advice
The heating system must be sized appropriately based on the power of the boiler. If necessary, rely on a thermo-technician. After
placing the stove and installing all fume exhaust pipes, you can connect the hydraulic system. It is recommended to connect the stove
to the system by means of ball valves or gate valves, in order to enable easy detachment, if needed.
3 bar safety valve (overpressure device)
It is mandatory to connect the safety drain of the thermo-stove to an adequate evacuation system. The connection can be made using
a rubber hose resistant to temperatures of at least 110 ° C.
Please note that in case of intervention of the 3 bar safety valve, part of the water contained in the system is expelled from the safety
drain.
⚠
It is forbidden to connect a shut-off valve to the safety drain outlet.
⚠
The water coming out of the safety valve could be hot! Danger of burns and damage to people and things!
⚠
The manufacturer is not responsible for any damage to persons or things caused by failure to connect the safety drain or by
an inadequate connection.
Expansion vessel
Check that the expansion vessel fitted as standard on the stove is sufficient for the volume of water contained in the system. Other-
wise it will be necessary to install an additional expansion vessel on the system.
Anti-condensation valve
In solid fuel stoves, to avoid the return of cold water in the heating chamber during the heating phase, it is advisable to install in the
system an AUTOMATIC THERMOSTATIC VALVE (available on request) to improve combustion efficiency and stove life and also
reduce the condensation of fumes in the flue ways, with less deposits and tars.
Storage systems (puffer, boiler)
Solid fuel appliances are, by their nature, devices with high thermal inertia. To increase the heat output of the system, reduce the on
/ off cycles, reduce cleaning interventions and have hot water always available, it is recommended to install thermal accumulators in
the system, such as puffers for technical water or boilers for domestic hot water. There are many combined solutions on the market
(puffer tank in tank, pipe in tank, etc.), which allow to meet all needs.
