HE CHECKS TO BE RUN BEFORE INITIAL START

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 1.5 bar, bring it up to the appropriate

level;

- Ensure that 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 pushing the On/Off button "A" (see F

L.E.D. "B" will illuminate. Then push the button "C" in for central heating - the

L.E.D. "D" will illuminate. This will start the circulation pump. After 7 seconds, the

boiler will signal a shutdown due to ignition failure. Leave the boiler as it is until

all of the air has been bled from the system.

- Loosen the cap on the head of the pump to eliminate any air pockets;

- Repeat the procedure for bleeding the radiators of air;

- Check the system pressure and, if it has dropped, open the filling loop

again to bring the pressure back up to 1.5 bar.

2. Make sure that all gate valves are open;

3. Turn on the gas cock and check the seals on the connections with an approved

soap solution and eliminate any leaks.

In order to access the inside of the boiler, it is necessary to

unscrew the fastening screws "A" of the control panel located on

the lower part of the panel itself.

The control panel moves downward and when pulled forward

rotates on two lateral hinges.

The panel stays in a semi-horizontal position, which allows

access to the inner parts of the boiler.

In order to increase the manoeuvring space, it is possible to raise

the control panel and rotate it to a fully horizontal position.

To dismantle the front casing panel it is necessary to:

1 - Remove the two screws "B";

2 - Move the front casing panel up and lift forward.
