The boiler operation can be changed over from methane gas
(G20) to Liquid Gas (G31) or vice versa, an operation that must
be performed by a CORGI registered Gas Engineer.
To change the type of gas it is necessary to proceed as follows:
1. Before starting ensure both the gas and electrical supplies
to the boiler are isolated and the boiler is cool.
2. Remove the casing as indicated in Section 3.2.
3. Remove the silencer
4. Disconnect the electrical connection of gas valve and fan.
5. Remove the three torx screws of the air gas connections
(see Fig. 3.32) and loosen the nut under the gas valve
(see Fig. 3.33)
5. Remove all the mixer/fan/gas valve group (see Fig. 3.34)
6. Unscrew the four torx screws and disconnect the gas valve (see
Fig. 3.35).
7. Insert the diaphram into the gas valve (see Fig. 3.36)
8. Reassemble in reverse order.
