How to change gas (Figure 5.3
p. 39)
1. Cut o ff electric power and gas supply.
2. Unscrew the hexagonal seal that connects the gas pipe (A)
to the nozzle holder fi tting. Take care not to lose or damage
the internal gasket (B) nor the o-ring (D).
3. Move the gas pipe and pull out the nozzle (C), using a screw-
driver if necessary.
4. Remove the gasket (B) and o-ring (D) from the old nozzle
and mount it on the new nozzle.
5.
Insert the new nozzle into its seat, checking the concordance
with Table 5.8 p. 39. For the R50 gas unit heater only, and
only when fed with G25.1, G27 and G2.350 gas, the existing
nozzle must be removed.
6.
Reassemble the gas pipe, checking that the round gasket in
the seal is well positioned. Close the seal applying a torque
of 62±2 Nm.
7. Adjust the appliance for the new gas type, adjusting the
burner pressure as described in Paragraph 5.2.1
p. 35.
8.
Replace the sticker indicating the gas type on the appliance
with the sticker for the new gas type.
For the R15 model, in case of changeover from any type
of gas to LPG, G30 or G31, and vice versa, it is necessary to
replace also the component shown in Figure 5.4
p. 40
with the one supplied with the gas change kit, indicated
by the letter A.
