3. INSTALLATION OF THE APPLIANCE
3.1 General Instructions
BOILER INSTALLATION MUST ONLY BE PERFORMED BY QUALIFIED PER-
SONNEL, IN ACCORDANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS
TECHNICAL MANUAL, THE PROVISIONS OF CURRENT LAW, THE PRESCRIP-
TIONS OF NATIONAL AND LOCAL STANDARDS AND THE RULES OF PROPER
WORKMANSHIP.
3.2 Place of installation
The boiler unit must be installed in a speci
fi
c room with ventilation openings to the
out-side as prescribed by current regulations. If there are several burners or suction
units that can work together in the same room, the ventilation openings must be
sized for simultaneous operation of all the units. The place of installation must be
free of
fl
ammable materials or objects, corrosive gases, powders or volatile sub-
stances that, conveyed by the burner fan, can obstruct the internal lines of the burn-
er or the combustion head. Theroom must be dry and not exposed to rain, snow
or frost.
If the unit is enclosed in a cabinet or mounted alongside, a space must
be provided for removing the casing and for normal maintenance opera-
tions.
3.3 Plumbing connections
The heating capacity of the unit must be previously established by calculating the
building’s heat requirement according to the current regulations. The system must
be provided with all the components for correct and regular operation.
It is advisable to installshutoff valves between the boiler and heating system allow-
ing the boiler to be isolated from the system if necessary.
The safety valve outlet must be connected to a funnel or collection pipe
to prevent water spurting onto the
fl
oor in case of overpressure in the
heating circuit.Otherwise, if the discharge valve cuts in and
fl
oods the
room, the boiler manufacturer cannot be held liable.
Do not use the water system pipes to earth electrical appliances.
Before installation,
fl
ush all the pipes of the system thoroughly to remove any resid-
uals or impurities that could affect proper operation of the unit.
Carry out the relevant connections according to the diagram in cap. 5 and the sym-
bols given on the unit.
