The CONNECTION BETWEEN THE BOILER AND THE FLUE must comply with the current
regulations and legislation and consists of rigid hermetically sealed pipes resistant to high
temperatures, condensation and mechanical stress. For sealing the joints, use materials t hat can
withstand at least 250°C.
Badly sized and shaped flues and couplings between boiler and flue can amplify the combustion
noise, negatively affect the combustion parameters and cause condensation problems.
CAUTION: non-insulated outlet pipes are a potential source of injury.
HYDRAULIC CONNECTION
The choice and installation of the system components is the responsibility of the installer who must
operate in accordance with correct working practice and the cu rrent legislation.
The following recommendations should be observed:
-
The boiler fittings must not be put under strain by the weight of the system connection pipes as
this can cause damage to the boiler and all pipework must be adequately supported .
-
Cut-off devices must not under any circumstances be fitted between the boiler and the
expansion vessel and between the boiler and the safety valves.
-
The expansion vessel must be correctly sized (there must be no leaks of water due to normal
expansion) and, if the expansion vessel is closed, the safety valves must open only in
exceptional cases in order to minimise any subsequent introduction of water and in any case
to ensure that it is introduced and controlled by one single point in the s ystem.
-
Ensure that the safety valve outlets are connected to an outlet tundish and a discharge over a
drain. If not, when the valves cut in they will flood the room and the manufacturer will accept
no liability for this.
-
Ensure that the hydraulic pipes are not used as earth connections for the electrical or
telephone system. They are not suitable for this use and can rapidly deteriorate leading to
serious damage.
-
Before connecting up the boiler, wash all the system pipes to remove any debris that coul d
affect correct operation.
-
The water to fill the system must have the following technical features: hardness < 1 °F,
acidity pH > 9; otherwise a system for water treatment should be provided.
-
If the mains water supply contains impurities, a suitable filter must be fitted
-
Avoid any accidental contact between the heating system water and the sanitary water as the
former is not drinkable.
