what else? well the AARON engineer was to come...to do the annual gas check...gill was to remember him from daldry's lab, too...go figure...anyway, he did the 'usual' whilst asking me where the 'badge' for the boiler was...I referred him to R G FRANCIS documentation...seeing as this annual gas boiler check has been done every year...and there was nothing 'in that box' i.e. the description of the unit/appliance...see previous notes upon 'all of that'...i.e. the doctors made to put a boiler together from scratch, by the ill...as a 'test' of their intelligence etc etc....

anyway, the plumber showed me how easy it was to top up the boiler...just turn the black lever anti-clockwise until you hear the water running...fill it up...and then turn it off...go figure.
