8. Generate a heat demand as follows, for appropriate type (boiler or water heater):
• BOILER: by pressing button
to its maximum setting.
• WATER HEATER: by pressing button
to its maximum setting.
9. Generate a heat demand as follows, for appropriate type (boiler or water heater):

10. Gain access to the installer menu (See Section 5.4) and set parameter 2115 to HIGH. Now
the unit will run for 20 minutes at maximum input;
11. Check the manometer to make sure the gas supply pressure does not drop below 3” W.C.
(7.6 mbar). If the gas supply pressure is lower than 3” W.C. it means that your inlet gas line
or your gas pressure regulator is not correctly sized.
CAUTION!
DO NOT adjust the screws “E” and/or “F” (Figure 4-2). These
screws are factory-set for the correct gas flow and outlet pressure.
Attempting to alter the gas valve setting could result in damage to
the valve, causing potential severe personal injury, death, or
substantial property damage.
12. After verifying the correct gas pressures:
a) Return to parameter 2010 and set to OFF.
b) Close the manual gas shut-off valve (Figure 3-40).
c) Disconnect the manometer.
d) Turn the screw in pressure connection “D” in Figure 4-2, clockwise until snug.
e) Check pressure port “D” (Figure 4-2) for any gas leaks.
