13.1 SINGLE GAS VALVE MODELS (POWER HT 1.850 AND 1.1000) FIGURE 12a
Proceed as follows to adjust the single gas valve:
• Insert the fume analysis probe into the fume sampling hole as instructed in section 17 ( gure 15).
• Switch on the boiler, activating the "setting function" from the control panel by pressing and holding the
and
keys simultaneously until the
13a and 13b.
• Press the
key to set the maximum heat output, with the display showing 100% ( gure 13a).
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.
• Turn the gas valve adjuster screw V so as to set the CO
and in table 2.2 for propane (LPG):
-
Turn the screw anti-clockwise to increase the CO
-
Turn the screw clockwise to decrease the CO
• Press the
key to set the minimum heat output, with the display showing 0% ( gure 13b).
• Turn the gas valve adjuster screw K so as to set the CO
and in table 2.2 for propane (LPG):
-
Turn the screw clockwise to increase the CO
-
Turn the screw anti-clockwise to decrease the CO
13.2 DOUBLE GAS VALVE MODELS (POWER HT 1.1200 AND 1.1500) FIGURE 12b
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 ue gas analyzer in the sampling port as indicated in heading 17 - gure 15.
• Switch on the boiler, activating the "setting function" from the control panel by pressing and holding the
and
keys simultaneously until the
13a and 13b.
• Press the
key to set the maximum heat output, with the display showing 100% ( gure 13a).
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 (POWER HT 1.1150 and 1.1200) or 2½ turns (POWER HT 1.1500), repeating the steps
described above.
• Turn both gas valve adjuster screws (V1) and (V2) so as to set the CO
natural gas (G20) and in table 2.2 for propane (LPG):
-
Turn the screw clockwise to decrease the CO
-
Turn the screw anti-clockwise to increase the CO
• Press the
key to set the minimum heat output, with the display showing 0% ( gure 13b).
• Turn the adjuster screw K1 of gas valve 1 so as to set the pressure value (Pout) as indicated in table 2.1
for natural gas (G20) and in table 2.2 for propane (LPG):
