Thanks to a couple of geniuses on this group - Ed Sirett & Heliotrope
Smith - I now have an up-and-running boiler!
One small problem. The condensation drain is producing white steam and
there is a chemical smell in the air. Is this normal? (it's a
condensing boiler and the flue is also producing steam).
It sounds like you have an empty condensate trap, so the flue
gasses including steam are being expelled through the condensate
drain. This could be very dangerous if the boiler is producing
any CO. Look at the commissioning instructions for how to fill
the condensate trap. (On a Keston, and quite likely most other
condensing boilers, you could simply pour a pint of water down
the flue to do this.)
