13.1 single gas valve Models (Fs 90 - 105) Figure 14a
Proceed as follows to adjust the single gas valve:
•
Insert the flue analysis probe into the flue sampling hole as instructed in section 17 (figure 17).
•
Press and hold the

key to set the maximum heat output, with the display showing 100% (figure 15a).
caution: in the event of the boiler failing to ignite, or when replacing the gas valve, the recommended
procedure is to tighten the adjuster screw (v) fully and then back off 3 turns, repeating the steps
described above.

13.2 double gas valve Models (Fs 130 - 160) Figure 14b
Proceed as follows to adjust the double gas valve:
• Connect a pressure gauge to the P1OUT pressure measurement hole on valve 1.
• Insert the probe of the flue gas analyzer in the sampling port as indicated in heading 17 - figure 17.
• Switch on the boiler, activating the "setting function" from the control panel by pressing and holding the

• Press the
key to set the maximum heat output, with the display showing 100% (figure 15a).
caution: in the event of the boiler failing to ignite, or when replacing the gas valves, the recommended
procedure is to tighten the adjuster screws (v1) and (v2) fully and then, depending on the model, back
off 2¼ turns (Fs 130) or 2½ turns (Fs 160), repeating the steps described above.
• Turn both gas valve adjuster screws (V1) and (V2) so as to set the CO
