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
.
0m

so you
achieve
18

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)
