Unhappy Old boiler can't light up

Nation-US Radiator (Crane), Model 101-4

Ignitor has light on, water leverl is normal (it was low this morning, may cause the boiler shut off automatically. I added water ), but even after I adjusted room temperature to high, still can't light up the boiler.

Can't find any manuals for this boiler, but here is some pictures.

Is this a gas-fired boiler? Steam or hot water?

I can't view your photos.

Is there any way I can force the boiler light up by pass that temperature control, just to see if the boiler is still ok?

Talking

Problem was solved, now the heater is on!

I followed the instructions today by turning off the main electrical switch before open the pilot line valve. Although I don't know the reason why.

1) Set room thermostat for lowest possible temperature
2) Make sure the main shut-off valve and pilot line valve have been off at least 5 minutes.
3) Turn off main electrical switch then open pilot line valve.
4) Depress red reset button on gas valve or pilot switch. Light pilot and release button after 30 seconds
5) With self generating controls, omit step 4, light pilot.
6) Open main shut off valve and turn on main electric switch burners will ignite when thermostat setting is above room temperature.
