Boiler saga part #? .......
functioning fine, but still a residual kero whiff in the morning, after being off overnight ??

Not so much a fumey smell as the smell of wet kero ?
cabinet still dry and couldn't see anything obvious .. burner out - nozzle dry as

so been eyeballing it regularly as it's worse when cool - dissipates when warmed up - really bloody odd ...
wiped everything off with tissue and getting nothing - nada - no signs of a leak for several days.
so up earlier than usual on Tuesday, 'fore going to take the kids to school, before the morning fire up occurred - lying on the floor looking for ANY signs of kero..
and can see a droplet / weep on the pressure adjusting screw - sod all really, but shouldn't be there .. dried it off with the edge of a tissue and it re-appeared

lit the boiler and within ten minutes, had stopped ....
turned it off and went and sorted the kid's school run ....
came back to a cold boiler and we had a repeat performance
miniscule amount but - wet (smelly) kero
went up a box and found the new pump I'd bought last year thinking the bearings were on their way out (turned out to be the motor bearings) and pulled the adjuster body out to see what was behind it and the screw out to see how it sealed. 'O' ring job on the spindle - AHA!! .. new one was a green nitrile seal, so needed to order a selection box ..

duly done and awaiting its arrival.
replaced the adjuster in the new pump and set the adjuster as close to where it was when I'd pulled it out
Particularly 'niffy' this morning and case/cabinet was 'moist' to the touch when I looked (doesn't take much kero to give you a film on yer finger tips)
both kids all day (Clara not 100% this morning so stayed 'home' with us today)
soon as they'd gone, 'bout 4 ish I'm on the case


laid on the floor I can now see a weep at the adjuster screw and the pump body is damp, from it working its way down it,

'fore ending up on the cabinet base.
dried it all off with tissue - AGAIN - and obviously disturbed the adjuster screw - didn't turn it, just disturbed it and it went from a weep to a miniscule 'flow' - smoking gun located properly !!
so went up the box - again - and pulled the adjuster body and screw complete out of the new pump, grabbed my pressure gauge and some suitable spanners and back down the house
pulled the test port bung out and dropped the gauge into it .. wanted to check its running pressure was as the book said - 8bar - yep, bang on 116psi running...
boiler off, kero line turned off, gauge back out - couldn't get a spanner on the damned adjuster body with it
in situ
and swapped out the old for the new.. reconnected the gauge and fired up the boiler - hadn't been a bad guess, when I reassembled the adjuster before - just over 120psi showing, so backed it off to the 116psi/8bar and let it run for 15 minutes.
steady as ..

gauge out, test port re-plugged with the port extension, I'd removed (easier to get the gauge in the port than the extension) and ran it up again whilst I cleaned up the mess.
All stop for tea, then went and put it all away ..
the old adjuster was actually 'wobbling' in the body when I looked at it and was less than finger tight in it's mount - when I spun it out, the 'O' ring'd gone flat - amazed it'd still been sealing at all - it was so loose
when I extracted the 'O' ring off the spindle it was so brittle it split/snapped at the first slightest effort to remove it and was hard as ..
and a rubber, not a nitrile, as the new one is .....
found a suitable replacement from one of my many selection boxes and refitted the assembly back in the new pump - bagged the old seal and labelled it, 'fore dropping it in with the new pump into its box - might replace it with a nitrile, when they arrive.
so ... all in all - a combination of circumstances/issues/coincidental factors, that has conspired to '
do my swede' ..
have cleaned the cabinet out as best I possibly can, (tissue is a great 'sponge' for absorbing stray kero), but the offending kero will have tracked under the fire box and has been soaked up by the lower edges of the glass wool lagging jacket around it, so it is going to continue to 'niff' a bit until it all evaporates - eventually - hopefully soooooner rather than later

just looked at it and all is dry and
'hunky dory'
hopefully I will not have to get down on my knees again any time soon - apart from to fit the placcy cover/shield, I've left off for now for observation purposes - give it a week and see what it's like



...
will hopefully have cleared all residual, by then and it'll have returned to its normal 'don't know it's there' performance
