The checks to be run before initial start-up are as follows:

1. Make sure that:

- the screw on the automatic air valve has been loosened when the system is full;

- If the water pressure in the system is below 1 bar, bring it up to the appropriate level;

- Check to see whether the gas cock is closed;

- Make sure that the electrical connection has been made properly and that the earth

wire is connected to an efficient earthing system;

- Supply power to the boiler by pressing the On/Off switch <L> - the L.E.D. "I" will

turn on - turn the selector knob "C" to the <winter> setting. This will start the circula-

tion pump. After 7 seconds, the boiler will signal a shut-down due to failure ignition.

Leave the boiler as it is until all of the air has been bled from the lines.
