instantaneous water heater advice

[jimmy t]

I have been recently working on a Chaff 2T water heater and have replaced both diaphram and gas section and this still hasn't solved the problem of casing getting really hot and flames really high and yellow, I have also replaced case seals and merchant guarentees me that gas section set up for natural gas..... any suggestions please

Burner pressure check and gas rate in case meter pressure wrong would be a good start

Brand new or old?

Or rather has it ever worked correctly?

I take it that you are not GSR jimmyt otherwise you wouldn't need to ask such a question!

Any kind of indicators such as melted droplets on the floor of the chamber? sounds of Birds tweeting louder than usual? Custard complaining of headaches or nausea????? Geeeeeezzzzzzzz!

Unlikey, it's a room sealed appliance.

Now you see MM ... case front getting hot has me worrying straight away about the actual case seals TBH They're not designed for the heat generated should the poc's be present within the appliance chamber. Heat to that extent tend to disintegrate seals in my experience ..... However if the said heater is fan assisted then hopefully it's negative pressure. I don't know off hand the heater in question TBH

Sorry DG, your far too young to comment on this thread lol.

The water heater is natural draft balanced flue and the only electrics on it is a piezo ignition.
The OP hasn't a clue what he is doing and should refrain from touching the appliance as IMHO it is ID.

I totally agree MM hence my original attempt at sarcasm...! lol .... I'm a bit more subtle than you eh?

Nah, you fell for my comment about the condense pipe on a Vaillant 242e combi.
Everyone knows that the Turbomax and not the 242e was condensing.

Spot the mistake

I do MM and I thought What TFuk you on about ... This boiler was way before the turbomax or condensing boilers , maybe I missed the punchline or whatever
