Ignition
• Open the gas isolation valve on the boiler.
• Purge the air from the pipe work to the gas valve.
• Turn on the 3amp electrical switch or insert the plug to the
boiler.
• Turn the heating and hot water control knobs onto their required
temperatures (see par. 1.4).
• The boiler is now ready to function automatically whenever hot
water is drawn or both the time clock and room thermostat call
for heating.
Turning off
Turn the knobs (ref. 1 and 2 Fig. 1) onto minimum.
If the boiler is turned off this way, then the P.C.B is still powe-
red.
Hot water and heating operation are disabled, the display shows
; but the frost protection function remains active
The frost protection will not work if the electricity and/or gas supply to the unit are cut off.
To avoid damage caused by freezing during long shutdowns in winter, it is advisable to drain all
water from the boiler, the tap water and the system water; or drain off just the tap water and
add a suitable antifreeze to the heating system, as prescribed in chap. 2.3.
Summer/winter Switchover

switch between summer and winter operation or turn off the domestic hot water .
