5.2.3 Ventilation The ventilation of the boiler room must satisfy the applicable
national and local standards and regulations (see Supplement).
5.3 Connections
With regard to ventilation, pay particular attention to the following
points:
a Observe the applicable national and local standards and
regulations for the dimensions of the openings and the protection
for any mechanical ventilation
b Ensure that the air inlet openings are transversely placed in
two opposite walls
c Fit inlet gratings with a large width and a small height
d Ensure that the correct amount of high level ventilation exists
e If the air supply is inadequate, it may be necessary to fit a
mechanical means of providing adequate ventilation.
5.3.1 Gas connection The gas connection must be made by a recognised installer in
accordance with the applicable national and local standards
and regulations (see Supplement).
The gas connection is made at the rear of the boiler.
Types 00 - 03 are not suitable for immediate connection to a
100 mbar natural gas system. The pressure of the gas supplied
to the unit must be reduced to 25 mbar for natural gas or 50
mbar for propane with the use of a gas pressure regulator.
From type 04, all boilers are suitable for gas supply pressures
of both 25 and 100 mbar on natural gas.
The loss of pressure in the connecting pipes must be such that,
at maximum boiler capacity, the pressure must never fall below
18 mbar for natural gas or 30 mbar for propane.
5.3.2 Electrical connection The electrical connections and provisions must comply with the
applicable national and local standards and regulations (see
Supplement).
The units are wired in accordance with the electrical diagram
supplied with the appliance.
The electrical connections, the terminals and the boiler pump
relay are mounted in a separate connection box behind the
front panel (extrusion profile, see fig. 4).
