Checks Before Installation - PIETRO FIORENTINI GOVERNOR 30051 Use And Maintenance Manual

7.1.3 - CHECKS BEFORE INSTALLATION

With respect to its design pressure (DP), the equipment does not require any further safety device upstream to protect
against any overpressure when, for the upstream reduction station, the maximum incidental downstream pressure is:
MIPd = Maximum incidental downstream pressure value (for further information, see UNI EN
12186:2014).
ATTENTION!
If the installation of the equipment requires the field application of compression fittings, these must be
installed in accordance with the instructions of the manufacturer of the fittings themselves.
The choice of fittings must be compatible with:
• the use specified for the equipment;
• the plant specifications when required.
Before installation, it must be ensured that:
• the flow direction is observed as shown on the equipment;
• at least one shut-off valve is installed upstream;
• at least one shut-off valve is installed downstream;
• the data on the identification plates attached to the equipment (see section 2.8 of the manual) correspond to the
requirements of the connected combustion appliance(s);
• the equipment has not been damaged during transport;
• the intended installation compartment meets the provisions in force on safety and is away from any possible damage
of mechanical origin, away from sources of heat or naked flames, in a dry place and protected from external agents;
• there are no impediments that could hinder the installation operations;
• the inlet and outlet pipes are at the same level and able to support the weight of the equipment;
• on the input/output connections are totally free of mechanical stress;
• inlet/outlet pipe connections are parallel, clean and undamaged;
• the inside of the upstream pipe is clean and free of processing residues such as welding slag, sand, paint residues,
water, etc....
