Before starting up, read the instruction manual carefully

and makes sure that

The gas pipe is adequately vented. If inadequately

vented, heavy

CO2

fluctuations will occur in the first

minutes of operation.

The tank is well vented in the case of liquid gas equipment

The gas pipe is tested for tightness

Test the gas inlet pipe under pressure only up to the

gate valve.

Note that the compact gas fitting cannot

withstand the high test pressure.

The heating system and if possible the storage tank are filled

and vented.

The electrical connection was properly carried out.

The hydraulics of the appliance is properly connected

The condensate trap

(siphon)

is adequately filled.

Check once again to make sure all necessary safety devices

are properly installed.

Then fill the appliance and the heating system.

•

Filling process

To determine the correct filling pressure, follow the manufacturer specifications of the

ressure expansion tank.

We recommend

that you proceed

according to

MHG information on

“Sizing of pressure expansion

tanks”. A filling pressure of 0.5 to 0.8 bars above the inlet

pressure

of the

pressure expansion tank

is sufficient

To vent the

boiler, open the hand vent on the h

eat exchanger

and let the air

escape into a pail through the enclosed plastic hose.

Do not end filling until

ProCon

and the heating system

have been completely vented
