gas valve

and ignition unit

Danger

Escaping gas leads to a risk of

explosion.

Check all fittings for gas tight-

ness.

Please note

The use of leak detection

spray can result in incorrect

functions.

Leak detection spray must not

reach electrical contacts or

seal diaphragm openings on

the gas valve.

Checking the diaphragm expansion vessel and system pressure

Note

The diaphragm expansion vessel can

lose some charge pressure over a time

in use. When the boiler heats up, the

pressure gauge will indicate a higher

pressure of 2 or 3 bar. The safety valve

too can respond and discharge excess

pressure.

Check whether the installed diaphragm

expansion vessel is adequate for the

system water volume.

Carry out this test on a cold system.

1. Drain the system or close the cap

valve on the diaphragm expansion

vessel and reduce the pressure until

the pressure gauge indicates "0".

2. If the pre-charge pressure of the dia-

phragm expansion vessel is lower

than the static system pressure, top

up with nitrogen until the pre-charge

pressure is raised by 0.1 to 0.2 bar.

3. Top up with water until the charge

pressure of the cooled system is at

least 1.0 bar and 0.1 to 0.2 bar higher

than the pre-charge pressure of the

diaphragm expansion vessel.

Permiss. operating pressure: 3 bar
