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 dataplate. Whenever a gas dif-
ferent from that for which the unit is arranged has to be used, a conversion kit will be re-
quired, proceeding as follows:
1. Disconnect the power supply to the boiler.
2. Using the special key supplied, open the cabinet of the upper exchanger body.
3. Detach the electrical connections from the gas valve controller.
4. Loosen the gas valve (fig. 50 e fig. 51) fixing ring "A".
5. Undo the two fixing screws "B" and remove the fan assembly as indicated in fig. 50
for the model ENERGY TOP B 80 - 160 and in for fig. 51 the model ENERGY TOP
B 125 - 250.
