THERMAL PLANT

BOILER ROOM

As a rule, regulations in force should be always observed. Premises in which boilers will be installed should be sufficiently
ventilated and guarantee access for ordinary and extraordinary maintenance operations.
FLUE
The boiler that now equips your heating system uses a weakly pressurised burner which cannot resist against the resi-
stances of the flue. The connection pipe must be as short as possible and must slope upwards in the direction of the flue
gas flow with recommended gradient of no less than 10%. Flues must be insulated in order to avoid losses in tempera-
ture over 1°C for each output meter. The flue must be fitted at the bottom with a collecting chamber for any solid matters
discharged or a hole should be drilled for gas sampling purposes.

Ensure that the hydraulic pressure measured after the reduction valve on the supply pipe does not exceed the operating
pressure specified on the rating plate of the component (boiler, heater etc.).
- As the water contained in the heating system increases in pressure during operation, ensure that its maximum value does
not exceed the maximum hydraulic pressure specified on the component rating plate.
- Ensure that the safety valve outlets of the boiler and hot water tank, if any, have been connected to an exhaust funnel in
order to prevent the valves from flooding the room if they open.
- Ensure that the pipes of the water and heating system are not used as an earth connection for the electrical system as this
can seriously and very rapidly damage the pipes, boiler, heater and radiators.
- Once the heating system has been filled, you are advised to close the supply cock and keep it closed so that any leaks
from the system will be identified by a drop in hydraulic pressure indicated on the system pressure gauge
