boiler vibration!

[Cereal]

I've just transferred the wort into my boiler and started ramping up the heat. I can hear and feel vibration coming from the heating unit. This doesn't bode well!

Also, I have filled my boiler to the top level and still have 4-5 lit of wort to add. Can I add it mid boil process as losses drop the level?

I giuess it's a burco or similar don't know about the vibration, but as regards the wort additions, I do this without problems, just make sure it all gets a good boil

Well, it made it through the boil. IC is in and doing its job so thank fook it made it. Got a Mona Fire Rock clone prepped for Thurs so didn't want it to have died before that!
