The table below shows the gas pressure values at the burner for each model of
boiler:
OUTPUT (kcal/h) BURNER PRESSURE IN
mb OF WATER GAUGE
BOILER 24KW
Natural Propane
20382 18.0 35.0
18060 13.3 27.0
16340 11.2 23.0
14620 8.6 19.0
12900 7.0 14.8
11180 5.3 11.9
9460 4.0 8.6
7740 2.3 5.8
6536 1.3 3.2
Ignition Pressure 4.0 8.0
Ø Injectors (mm) 1,14 0,75
Important: It is very important to know that when you are mak-
ing the gas regulation you may use the values of this table.
The values should be equal or lower never higher. For example
if you are making a maximum natural gas regulation the
table says 18
.0mb so you achieve 18.0 mb or less than 18.0mb

Changing the gas:
This boiler is designed to function using
PROPANE GAS or NATURAL GAS
GAS.
To change the type of gas used, the only com-
ponents that need to be changed are the injec-
tors. The injectors corresponding to the gas to
be used are fi tted as shown in Table 3.
After the injectors have been changed, the gas
is to be adjusted depending on the type used,
as shown in Table 3.
- Maximum pressure adjustment
(@Gas valve)
- Minimum pressure adjustment
(@Gas valve
- Ignition pressure adjustment
(see step 5 T5 adujusting boiler parameters)
