If the boiler is to be connected SILVER 24T - 34T to a collective flue or to a single flue
with natural draught, the flue or chimney must be expressly designed by professionally
qualified technical personnel in conformity with the current regulations and be suitable
for sealed chamber units equipped with fan.
3.7 Condensate drain connection
The boiler has an internal trap for draining condensate. Fit the inspection union A and

4. SERVICE AND MAINTENANCE
4.1 Adjustments
Gas conversion
The unit can operate on natural gas or LPG and is factory-set for use with one of these
two gases, as clearly shown on the packing and on the data plate. Whenever a different
gas to that for which the unit is arranged has to be used, a conversion kit will be required,
proceeding as follows:
1.
Remove the front panel (see *** 'Opening the front panel' on page 26 ***).
2.
Undo the screw and rotate the control panel (see fig. 21).
3.
Unscrew the ring C and remove the gas pipe A from the gas valve (see fig. 22).
4.
Replace the nozzle B inserted in the gas pipe with that contained in the conversion
kit, interposing seal D (see fig. 22).
5.
Reassemble the gas pipe A and check the tightness of the connection.
6.
Apply the label, contained in the conversion kit, near the data plate.
7.
Refit the front panel.
