And if you *have* managed to spill iquid CO onto your boiler, how will you
know, apart from maybe cracks due to localised cooling, that you have
spilled any, given that it will evaporate immediately?
I wonder if you mean CO leakage from boiler (eg from flue or burner area due
to incomplete combustion) rather than spillage on, which implies a liquid.
Liquid N2, bp 77K IIRC, takes a few seconds to boil away if spilled in
quantity. Pouring a thermos of unwanted liquid N2 onto the lab floor
was a very quick way of redistributing the dust and fluff into the
Spillage applies to gasses too.
In this context it means combustion products which fail to
be drawn into an open flue, and "spill" out into the room.
However, the RS in the boiler model number presumably means
Room Sealed, so in this case spillage shouldn't be able to
If you have CO from a room sealed appliance, it means you
probably have two faults:
1) it's generating CO due to poor combustion.
2) the CO is leaking into the house somehow, either because
it's not correctly room sealed, or because the CO re-
enters after leaving the flue terminal.
