To set timer on boiler:
Clock hands at current time.
Slide contol on clock face has 3 settings Top, Middle
and Bottom.
Top is usually an 'I' for ignition, and this is used when you want constant central heating.
Middle is your clock setting control, and used when you want to control heating to be on at certain times, as per the placement of your teeth on the outside of the clock face(Teeth in is usually times off/teeth out is usually times on)
Bottom setting 'O' is usually OFF for your heating.
**the reason I say usually is because some clocks are complete opposite I.E. 'O' is ON and 'I' is OFF!!!
Please remember that your main control knob must be on the Snow Flake setting for the heating to work on any timeclock setting.
