How to Use
NOTE:
In some circumstances, it is possible that the pipes (and possibly a radiator) heat up slightly after hot water is drawn. To
prevent this, simply close the central heating flow tap
31 (Fig. 2).
Remember to re-open it at the start of the heating season, when you switch the heating back on by rotating button
22 (Fig. 1)
or by turning the clock on.
Starting up (Fig. 2)
1. Ensure that the mains gas supply isolating tap is open and that the appliance is supplied with power.
2. Ensure that there is sufficient pressure in the heating circuit: the pressure gauge needle should be at a minimum of 1.2 bar
and a maximum of 1.7 bar when cold.
3. Ensure that the appliances gas inlet tap is open 33 (Fig. 2).
Your appliance is now ready to operate.
