SECTION 3: PLUMBING INSTALLER
In this section you can find all the necessary instructions to install F2 C Series heaters
from the hydraulic point of view.
3.1 GENERAL HEATER INSTALLATION REQUIREMENTS
The installation shall be made, according to the Manufacturer’s instructions, by qualified
service engineers.
By Qualified Service Engineers we mean the personnel with specific technical
skills in the field of the heating system components. In any case, if you need more
information please contact the Pre-Sale Department of ROBUR S.p.A. (tel. +39
035/888111).
An incorrect installation can cause damages to people, animals and property. In case of
erroneous installation, the Manufacturer cannot be held responsible for such damages.
The installation must be performed in compliance with the existing national regulations.
For the installation it is necessary to respect the following instructions:
- Dimension the duct system and the warm air and intake air diffusers taking into
consideration the characteristics of air flow, head pressure of the centrifugal fan,
and type of pulley utilised.
- In order to obtain the maximum comfort and efficiency from the installation it is
suggested to respect the following rules:
! Be careful that the air blowing out from the diffusers do not invest directly the
people
! Take into consideration the presence of obstacles (i.e. pillars).
- It is not recommended the installation of F2 C series in greenhouses or ambient
with high rate of humidity or similar atmospheric conditions because these units
have not been designed for this type of installation.
3.2 INSTALLATION SEQUENCE
Install the gas supply lines, the electric power lines, as well as the flue exhaust openings
and the combustion air inlet according to the approved installation project.
1 - Unpack the unit carefully checking that it has not been damaged during transport;
every unit is factory tested before shipment, therefore, if there are damages report
them immediately to the carrier.
2 - Make sure that an adequate gas supply from an efficient gas network is provided,
particularly if the unit is supplied with:
Natural Gas
Be sure that the pressure of the gas network, with the unit in operation, is set at 20
mbar (204 mm H
2
O) (allowed tolerance between 17 mbar and 25 mbar).
