pressure
6.7 - Controlling the combustion
agent air pressure
As the boiler has an air/gas ratio fixed in the factory, the gas
pressure at the burner is controlled indirectly by measuring
the pressure of the combustion agent air inside the boiler and
must correspond to that stated in the table in chapter 9, under
“Combustion agent air pressure”.
Proceed as follows for the check (refer to the Figures from
6.9 to 6.12):
1.- use a differential manometer with precision of at least 0.1
mbar (1 mmH2O);
2.- close the gas cock;
3.- open the boiler casing following chapter 8.2;
4.- remove the caps “A” (see figure 6.9);
5.- take the flexible hose “D”, which is found inside the
appliance and remove the cap “B” (see figure 6.9);
6.- insert the pipe “D” inside the hole indicated by the arrow
in figure 6.9;
7.- loosen the pressure point “H” in figure 6.10;
8.- take a silicone pipe with external diameter of 10 mm and
internal diameter of 7mm (detail “E” in figure 6.10) and
introduce it into pressure point “H”;
9.- insert pipe “E” into the hose as indicated in figure 6.11;
10.- connect the manometer to the two pipes “E” and “F” as
illustrated in figure 6.12, making sure to connect the pipe “E”
to the negative pressure point and tube “F” to the positive
pressure point;
11.- close the casing “B” in figure 8.1. It is indispensable
to have a reliable measurement;
12.- switch the boiler on;
13.- press the and RESET keys simultaneously
for more than 5 seconds to enter the “installer” menu,
confirmed by the appearance of the icon on the
display.
14.- using the and keys, access the
parameter
2010
;
15.- press the RESET key to enter the parameter and use the
and keys, to modify the value to
FAn
;
16.- press the RESET key to confirm the modification. Now
the fan will operate at maximum speed for 10 minutes.
17.- compare the pressure value read on the manometer with
that given in the table in chapter 9, “Combustion agent air
pressure”. If the pressure is at a lower value, check that
there are no obstructions in the combustion agent air/fumes
exhaust or that the air intake/fumes exhaust system is not
longer than envisioned in chapter 9 under “Max. length of
fumes pipe”;
18.- once the control has ended, press the RESET key again
to enter parameter
2010
and via the and
keys, change the value to
OFF
;
19.- press the RESET key to confirm the modification;
20.- hold the RESET key down for 5 seconds to exit the
“installer” menu.
At the end of the control, remove the tube “E”, close the
holes in the lower frame with the caps “A”, close the pipe
“D” using cap “B” and close the pressure point “H” again as
in figures 6.9 and 6.10.
