The only firebird condensing boilers I have serviced run on Kerosene, Billi, can you tell us what fuel it runs on please.

Firebirds consing section is at the bottom of the boiler, meaning the trap is under the floor pan. Trouble is that firebirds designers did not think that the lack of distance to the floor means that the drain pipemight have to flow uphill to reach a suitable drain. In firebirds office, gravity works in reverse from the rest of the universe.

The trap leaks because it cannot drain out satisfactorily.and therefore leaks where it joins the boiler.
One of my new oil customers with said oil boiler had this problem too except concrete floor severely acid corroded by condensate spillage.
I wanted to use a condensate pump nut headroom is too limited , so option now is to lift boiler off thebfloor a few inches to achieve suitable height clearance.
Which mean's replumbing boiler and moving flue pipe, all because the designers did not make the legs a few inches taller or place the condenser at the top of the boiler like say a Grant.

CO from oil boiler a lot less than from a gas boiler believe it or not.
Even low levels are now considered to be more dangerous over long term exposure than previously thought.
