TO SHUT DOWN THE BOILER
For short periods
Turn the boiler off at the time clock or system controls. Wait 6
min. and then turn the boiler control thermostat knob (1) to OFF.
Note the frost warning below.
For long periods
Turn the boiler off at the time clock or system controls. Wait for
6 min. and then turn the boiler control thermostat knob (1) to

TO RELIGHT THE BOILER
After short periods
Switch on the time switch or system controls and turn boiler
thermostat knob (1) to the required setting. The boiler will light

After long periods
Follow the lighting instructions above. Refill the system if it has
been drained.
FROST WARNING
If frost is likely, leave the boiler thermostat at position 6 and do
not turn off the gas cock. This will enable the built-in frost
thermostat to protect the boiler. Note that this may not protect
remote parts of the system, in which case a separate frost
thermostat should be fitted or the system drained and the boiler
shut down, as for Long Periods.

is OFF.
2. Ensure that the mains gas inlet cock (3) is open (groove in the
square head in line with the gas pipe).
3. Press in and release the overheat thermostat button (4).
4. Switch on the electrical supply to the boiler.
5. Ensure that all system controls (time switch, system controls
etc.) are calling for heat.
6. Turn the boiler thermostat knob (1) to position 6.
7. The boiler will light at Low rate and the Boiler On light (5) will be
illuminated. If it does not light the Lockout light (6) will be
illuminated. Press in and release the Lockout button (7). The
controls will reset and attempt to relight.
8. The burner will remain at Low rate for about 3 minutes before
going to High rate.
9. Set the boiler thermostat knob and the system controls to the
required settings.
