to do the work, they probably had to drain the boiler. this means they probably turned off the power, extinguished the pilot light or both. check to make sure the power is on to the boiler and the pilot is lit if your boiler has one.

After I turned it on, the boiler didn't fire (in the dark basement, I can usually see a flame and noise from the boiler when its going).
Was this installed incorrectly or is the boiler going to not operate well with that extra pipework? Should I not make the last payment? Thanks.
