so I picked up a big 4 ring cast iron burner on the weekend, looked at the tag and thought, 52Mj/h? fuck yeah!!!
set it up today to see how it goes ( it says on the label to have a 2.75Kpa regulator, and so that's what i have ) and frankly it doesn't seem to be putting out that much. outside ring has a half decent bit of flame spitting out, but each of the nozzles on the inner rings look like a bic lighter flame when it's almost out of gas...
the only thing that i can think of is at the end of the 4 iron sections of pipe that the gas nozzles are at the end of (as in the end with the taps) there are large washers on a thread that kind of cover up the end of the pipe but not really... i'm thinking maybe i have to seel the end up completely? i'll add a internet pic of a near similar burner.
any opinions would be much appreciated.
