must be rounded off with a radium of no
less than 20 mm; hydraulically equivalent
sections are also permitted;
– fitted with a chimneypot at its top, the
outlet of which must be outside of the so-
called reflux area to prevent formation of
counter-pressure preventing the products
of combustion from being freely released
into the atmosphere.
The minimum heights shown in fig. 4 must
be complied with;
– without mechanical intake devices at the
top of the flue;
– if the flue passes through or adjacent to
inhabited rooms, there must be no over-
pressure.
2.5.1 Flue size
The correct sizing of the flue is an essential
condition for efficient boiler operation.
The main factors to be taken into considera-
tion for calculating the section are the heat
input of the boiler, the type of fuel, the per-
centage of CO

, the mass flow of smoke at
nominal load, the temperature of the smoke,
the roughness of the internal wall, and the
effect of gravity on the draught pressure,
which must take into account the external
temperature and the altitude.
Table 1 shows specific parameters pertai-
ning to “RS Mk II” boilers.
2.6 BOILER BODY
The cast iron body is supplied ready assem-
bled; if it cannot enter the boiler room as-
sembled, it may be supplied dismantled.
Follow the instructions below to assemble
the body:
– Prepare components by cleaning the hou-
sings of the conical nipples with thinner.
– Introduce the plaster seam into the groo-
ve provided for the flue gas seal (fig. 5).
– Prepare one of the two intermediate hea-
ting elements with a 1/2” perforated stud,
lubricating the conical nipples with boiled
linseed oil before introducing them (fig.
5/a).
– Prepare the head, following the same pro-
cedure, and bring it into position adjacent
to the intermediate element. Add only one
element at a time.
– Assemble the heating elements using the
pair of tie rods supplied assembled with
their accessories, code 6050900 (fig. 6),
exerting pressure on the upper hub and
on the lower hub simultaneously. In the
event that the elements should not move
forward in parallel during this operation,
introduce the chisel into the tighter part
and force the two parts to be joined into
parallel. The two elements are properly
joined when their outer edges come into
contact.
– Introduce the plaster seam into the groo-
ve in the element just mounted and pro-
ceed to join the other elements until the
body is complete.
