Halstead room sealed HE boilers

[Bamber gaspipe]

Next week I am starting numerous installations using these boilers,( client`s choice). To be honest, I`ve never touched them installation wise because rightly or wrongly I have always shied away & put them in the same boat as Ravenheat (B&Q Diy rubbish) & some Ideal`s.
Any experiences/pitfalls etc, using these boilers would be gratefully received.

In the instructions it shows a picture of the pipe work and has them labeled flor and return. It doesn't tell you that one of the pipes can turn thru almost 360 degrees and end up on the other side of the config. Making it look like flow and return when it's actually return and flow. Does this make sense? It did in my head but now I'm reading it.........
Basically the pipes can move about and end up the opposite way to the diagram. And I can tell you it don't like working the wrong way round. DOH!

Thanks Chris, Can`t say I fully got the gist of that, judging by what I have seen on Halstead`s site the boiler doesn`t come with a separate jig like, say, Worcester Greenstar 28i junior. Can`t see how you can pipe flow/ return up incorrectly, can you elaborate?(I have crossed Cold mains in & Hot out, to my eternal shame) Only ONCE though

This was on the regualr boiler not a combi. The front pipe (flow I think) is on an elbow and can turn to be either side of the rear pipe. Thus making the diagram wrong.

On a regular boiler you only have 2 pipes, impossible to cross Mind you, at least you`re honest

 

[ChrisRoberts]

It's not imposible. The diagram in the instructions shows flow on right and return on the left. It doesn't mention that the flow can also go on the left by turning the pipe thru almost 306 degres.
Also the gas pipe to the valve from the connection can become lose in transit and create a leak inside the boiler.

You have fitted them so you must be right I`ll plough through as best I can...Thanks for advice...
