Question about Heating & Cooling

Open Question

Weil mclain - I have a cga 4spdn boiler. Trying to get it to start for the winter. I thought the technician who inspected it this summer said I only had to flip the wall switch (power to the boiler) to restart it. Near as I can tell, the pilot light is lit, but it is not firing up... I think the thermostats are functioning, but couldn't swear to that. Where should I begin to troubleshoot?

SOURCE: boiler won't fire even though the pilot is lit

Check if the ignition plug works. Upon putting your boiler on, a spark will normally trigger the
the firing. Then, check the ignition transformer if it works. Check the secondary voltage which is between 15000 to 20000 volts to trigger the ignition plug and the boiler to fire. If no spark,
have your ignition transformer replaced to make it work.

Light the pilot light on weil mclain gas boiler


Joanne If there is a standing pilot on the boiler. Put the gas valve to the pilot setting and push in on the valve while holding a long match or BBQ lighter @ the pilot assembly that is behind the small access port at the top of the gas train assembly. Dont hold the pilot knob doun without having a flane @ the gas outlet of the pilot assembly or gas will build up and could blow out of the port and hold the gas valve in for about a minute or two and let it go it should stay light when you let it go .If it does not sta lit and it IS a standing pilot there- is a thermo-coupling that may be bad If the pilot does not stay lit.
If there is an electronic ignition rather than a standing pilot then you do not need to light it will light itself if the electronic ignition is bad or if the flame sensor is dirty. If you remove the pilot assembly from the gas train and clean the flame sensor rod with a piece of .0000 steel wool it could help. If not you may want to call a licensed pipe-pitter ( OR plumber depending where you live and the local codes).
If you don't thing you could do it yourself then call a licensed pipi-fitter or plumber. (Gas only has to leak once for there to be a problem so please do call someone licensed if you don't think you could do it your self.), http://www.weil-mclain.com/en/weil-mclain/products-services/
Here is a link to the manufacturer you should be ale to fing your equipment and the install instructions, if you look around .You can download a PDF and print it
Good luck and stay warm

Have a water leak inside boiler keeps putting pilot light out


Not good at all. Check for a fill level probe/float/sensor that may be acting up causing the unit to over fill, or you may be looking at buying a new boiler.
