Back... Got a digital multimeter and a low volt thermostat, Honeywell rth1100b. Freezing in house now. Father thinks electrical issue was 2 heaters he had to help warm the house up faster. But that never happened before? When we twisted the wires the power was off, so no sparks. He doesn't want me to touch wires together while power is on - so I will use meter. I hope this works! House is a two unit, parents in one apartment - I'm in the other apartment.
Make sure the furnace breaker is on/ the on-off switch, which you may not have ( often on the side of the boiler or positioned higher than a normal light switch beside the closest door)is on. You can usually hear a little hum from the controls if the power is on.
Try checking the two terminals at the gas valve. If it has has 24 V , the pilot is on, the gas valve control is in the on position, and it isn't working then the way this boiler is wired up means that the gas valve will need to be changed.
If it doesn't have 24 V then you need to check the thermostat lines for 24 V. If nothing then check the thermostat lines at the boiler. If you have 24V there then the problem is somewhere on the thermostat/wire circuit.
I am assuming that you don't have any damper controls on the boiler vent?
