Installation of pressure relief valve
A safety valve with an opening pressure of 3 bar must be installed on the boiler. Each
heating element of the heating device must be protected against exceeding the maximum
operating pressure by the means of at least one safety valve (see EN 12828). These must be
so arranged as to prevent the maximum working pressure which may be generated in the
heating device or parts thereof from being exceeded. The safety valve must be located in the
boiler room or in the installation area of the device and must be well accessible. There must
be no locking elements, dirt traps, etc. between the boiler and the safety valve. The size of
the safety valve connection is determined according to the table depending on the maximum
heating output of the heating system.
The safety valve must be installed at the highest point of the heating element or at the
pre-flow near the heating element. This is the only way they can dissipate heat by releasing
hot water and steam. The installation position of the safety valve is optional, but the upper
part of the valve must not be positioned in a downward orientation. The supply may be up to
1 m long and must be laid flush with the nominal width of the valve inlet.
The outflow of the safety valve (discharge duct) must be installed at least at the
nominal width of the valve outflow under constant fall and shall be routed to the sewer
connection. The outflow duct may have a maximum of 2 arches and may be 2 m long. If a
duct longer than 2 m is required, the duct must be enlarged by one dimensions. More than 3
arches and 4 m in length are not allowed. The mouth of the discharge duct must be capable
of being inspected without obstruction and must be laid in such a way as to preclude any
danger to persons. If the discharge duct is directed into a funnel, the cross-section of its
discharge line must be
at least twice the cross-section of the valve inlet.
Risk of poisoning
In the room where the boiler is installed, vents and openings used for ventilation or
air supply must not be reduced or closed. If you smell gas (fumes) and think they may be
leaking out, leave the room immediately, open doors and windows and ventilate the room. If
the gas continues to leak, call a qualified person or a qualified installer. When loading fuel
into the boiler, do not leave the door open after loading. Observe the required chimney draft.
Explosive and flammable substances
Do not store explosives or flammable substances in the room where the boiler is
installed.
