code fs3.r1/4 thread 0.95 lpm-thats from the box i got mine in and buy a couple of tap washers for this,and some brass hoselock connections,to be fair if there is anyone to ask about this guys, its nat he help me soooo much in fitting mine-it works atreat now you can see the differnce it makes to cleaning,as a plus when trad you always have hot water to hand

.the l5 is not the be all and end all heater but for a low price its good to have,as an aside i've had the hose from the l5 to the hosereel burst twice due to heat and high pressure-am now going to use washing machine hose as it should withstand the heat more-its a learning curve :Doh i forgot to mention the heater comes with the wrong regulator you need a new one for lpg(red gas bottle)
