Instructions

1

Re-light the pilot light if you notice that you are not getting any heat from your home boiler. Most often, it is simply a case of the pilot light getting blown out. Allow adequate time for the boiler to heat up again after a pilot light has been re-lit.
2

Notice the amount of heat that you are getting from your radiators. If you realize that you are getting some heat, but not as much as you used to, you probably have a problem with low pressure. Check the boiler's pressure gauge for a reading of above 12psi. If it is below that, you'll need to add water to the boiler.
3

Look at the floor around your home boiler. If you notice that your boiler is leaking water, then check the pressure gauge for a pressure that is too high, or above 15psi. If this is the case, you need to empty some of the water out to get it to the proper pressure reading of 12-15psi.
4

Test the radiators around your home for the state of their repair. If some are emitting heat, but some are not, then you boiler is most likely leaking air into the pipes. Release the valve found at the top of the radiator to relieve the pressure. Close it immediately if water comes out.
5

Make sure that the bolts on your piping and connection are secured tightly. Schedule maintentance for your boiler yearly, so that you can make sure it stays in good repair.
