ADJUSTMENTS

Slow ignition —in the direction "-" OPALIS 5 : NATURAL GAS The servo gas device ensures automatic adjustment of slow ignition. —in the direction "+" diagram 9 . , , the temperature decreases the temperature increases and the flow rate decreases; and the flow rate increases. The flow rate of the hot water is adjustable : The correct burner pressure is between 8,5 mbar and 10,5 mbar (3,4" WG and 4,2" WG) for natural gas . If the burner pressure is within these values the heat input will be correct. If the pressure is not correct, check the inlet gas pressure at the test point on the left hand side of the gas section, see Hot water temperature adjustment 4diagram 9 ) acting directly on the waterflow rate. By turning this selector : These appliances are fitted with a temperature selector ( OPALIS 6 : LPG It is not possible to adjust the gas input, this hasbeen pre-set during manufacture. Check the burner pressure by fitting a suitable gauge onto the pressure test point situated on the bottom left hand side of the burner injector bar, see The correct burner pressure is between 32,5 mbar and 40 mbar (13" WG and 16" WG) for propane and 25,5 mbar and 31 mbar (10,2" WG and 12,4"WG) for butane. If the burner pressure is within these values the heat input will be correct. If the pressure is not correct, check the inlet gas pressure at the test point on the left hand side of the gas section, see

In all cases, always turn the hot water tap full on, inorder to allow the temperature selector to adjust the water flow rate automatically, maintaining the temperature selected constant. Important : to prevent premature scaling of theheat exchanger in your appliance, avoid leaving the selector ( 4 diagram 9 ) in the minimum flow-maximum temperature position, when the use of very hot water is not required.
