6.5 Start-up<br />
1 Open the gas valve.<br />
2 Switch on the appliance using the on/off switch on the con trol panel.<br />
3 Select the function “automatic operation q” using the func tion selector. (See also the operating<br />
instructions on the boiler).<br />
6.6 Shut-down<br />
The appliance can be shut down in three different ways:<br />
A The boiler continues to supply domestic hot water. Select the F function with the function<br />
switch.<br />
B The boiler is not operating and will only start up for auto matic frost protection. Select the i<br />
function using the function selector.<br />
C Shut down the boiler:<br />
1 Switch off the boiler using the on/off switch on the con trol panel.<br />
2 Close the gas valve.<br />
6.7 Warnings<br />
The appliance must be installed by a recognised installer. The operating instructions must be<br />
strictly observed.<br />
If the source of the fault cannot be found, the service organisa tion must be contacted. Never<br />
repair the appliance yourself.<br />
The condensate drain may never be modified or closed off. When a boiler is completely shut down<br />
in the winter period, there is a danger of freezing. Drain the water out with the aid of the filling/<br />
drainage valve. The user must never make any modi fications to the appliance or the discharge<br />
system.<br />
Annual checking and good maintenance are necessary in order to guarantee optimum performance.<br />
7 Commissioning<br />
7.1 General<br />
Commissioning must be carried out by skilled personnel. Fail ure to observe this condition will<br />
invalidate the guarantee.<br />
7.2 Commissioning<br />
y<br />
Water and the hydraulic system<br />
Take a sample of the water from the filling/drainage valve on the boiler and a sample of the makeup<br />
water. Determine the water hardness using the titration method. The water hardness must be<br />
less than 250 ppm. If the measured hardness is too high, the water must be softened.<br />
Determine the concentration of chloride in the system water. This may never exceed 200 mg/l. If<br />
this concentration is ex ceeded, the system must be flushed through and re-filled with low chloride<br />
water.<br />
Check the pressure of the system water. This must have at least the minimum value given in table<br />
14 (Operating pres sures).<br />
