keeps going out after a couple minutes, had a bester b4 this and that did the same thats why i replaced it.
any ideas?
it comes straight back on when you turn it off and on again or when the flow dead ends and starts back up. really peeing me off just wont stay on.
brand new system battery etc ok.
its an l5 think its the same as the corwoods one or very similar

What flow rate are you using?
It sounds like your using just enough to get it to fire up, but then as the hoses expand it could do with a bit more pressure through it.
-
around 40, literally 2 mins its out, ill try higher flow tomoz see if any difference

That's your problem.
I would say you need a minimum of 50 mayb even 60. You do need a fairly high flow rate to run these heaters.
What helps is to turn the right dial (flow) all the way down to the right. This means that the heater starts restricting the flow rate, and will then create the back pressure needed to fire the boiler up. Also the benefit of this is that if your using a flow rate of 60, then the heater throttles that down to about a 50, so you use less water, but are able to have the boiler fire up consistently.

also look at your calibration
-
can i ask how calibration effects it? do i need to recalibrate when running hot?

Aslong as your pump is running constantly then your ok. If when you turn your water off at the brush head and the pump builds up too much pressure then you need to turn your dead end down.

It dead ends when I turn water off at pole

Ok will try a higher flow rate see what happens, thanks

Don`t use a controller to restrict flow when you have a boiler in the system you should use the flow control on the boiler. When you turn your flow controller the gas system does not know the flow is down so then switches off in response to the low flow of water.
