gauge. If the heating system pressure is too low, top
up the water or notify your local heating contractor.
2. Open the shut-off valves in the oil lines (at the tank
and filter) or open the gas shut-off valve.

fuse or a mains isolator.
4. Switch the ON/OFF switch ON. After a short time,
the standard menu is displayed and the green ON
indicator illuminates. Your heating system and, if
installed, your remote control unit are now ready for
use.
