check to see the time clock is set with the clock symbol. there are three settings on analog clocks I , O and clock the I setting is constant running, the O setting is off and the clock setting is timer.
also try setting the thermostat up higher to see if the boiler fires.

most have an overrun built in for a few minutes. if much longer have you got a room thermostat anywhere to turn down
If it never turns off check the switch which controls ON/TIMED/OFF and turn to timed or off. if it still continues on timed then it's the timer
