Important: The following proce- dure must be followed when checking or setting the gas pressure:

1.Shut down the heater by switching off the mains current (switch off main switch);

2.Connect a manometer to the pressure test nipple to measure the burner pressure on the gas control.

3.Activate the heater and allow the burner to ignite;

4.Check the burner pressure. If necessary, reset it by means of the burner pressure adjusting screw. Turning it anti-clockwise reduces burner pressure. Turning it clockwise increases burner pressure;
