ravenheat csi85

[doyle]

installed in housing asscoiation property with flue approx 8 inchs below gutter and less than 2 mtr in height with no guard in a property built around 1 to 2 years ago.

the boiler cuts out and sometimes remains on low flame.
mfi says ravenheat csi85 condensing enginering or something but looks like a standard combi when front cover is removed.

inside is a clear yet small vessel that has a pipe at the top and white push fit connected to the bottom(looks like acidic water trap with flow pipe of some sort)

pipe runs down behind kitchen unit to unknown destination as it does not go through the wall to outside.

is this a condensing boiler or a combination boiler and what will the fault be.

Found this at this link. It is a condensing combi with a 3 year warranty http://www.ravenheat.co.uk/CSI85.htm

yeah i found installer stuff on website, tis a condensing boiler and sounds like ignition board needs replacing.

however still concerned over the installation as its where family live.

found to be used is rubber pipe to the storage vessel and plastic onwards(mfi says only plastic and no other materials)
also if you can refere to the instuction thread to see what you make of teh clearances it would be appreciated

thanks

doyle...i asked you before but you never answered. Are you corgi registered?

For someone who is working on boilers you don't half ask some daft questions

Example

is this a condensing boiler or a combination boiler.

Answer

BOTH

Cant download and read any of the Ravenheat manuals May be my PC or perhaps their site is as good as their boilers

 

[doyle]

dont worry they hazed it over aswell lol.


scatman,
no not registered at all matey, yeah ive got silly questions as im new and still not completed the portfolliofor acs , condenser standard combi well the csi 85 model ive never encountered before has condenser within the primary combustion chamber rather than ontop like every other condenser ive seen along with undefined terminoligy of what the boiler is on customer copy of service leaflets.
this was not work this was a visit to a family member where it was found to be at fault..no not worked on it all as its rented property and landlords problem not mine.

One wonders on what basis you are working on boilers in a HA property if you are not CORGI registered?

agile i wasnt i was visitng my family and was asked do i know what is wrong with it & top it up........ignition circuit board according to mfi.

as with scatmans serious looking frown hey hey wot a plumb its both....... i meant conventional combi boiler

have you looked at the csi 85's when you take the cover off its a single front covered combution compartment without external condenser. sure if i was working on it then i could have opened it up fully and would have known, but officail corgi registered guys feck the job up by leaving incorrect papers and so on, even passing their own incompetent jobs aswell, but me no i no im not 100% so i dont mind asking rather than ballsing it up

as for the condenser drain pipe could be anyones guess but its certainly not going through the external wall and going off the current fit then its proberbly open behind the kitchen units.

but seen as your a man of great knowlege who certainly knows his stuff i have another silly question for you.

electrical installation are joints permited with the boiler even if its done via those lawn mower styled connector plugs ????

If information on clearances or anything else isn't in the Installation manual then the relevant British Standard applies.

Yes that is a pretty silly question.

 

[Agile]

I suppose the answer to joints is that any joint is suitable if its safe!

Once I saw an electrician rewiring for SW Electricity in London who used polythene choc blocks on the ring main. Anyone who sees many electrical faults knows they easily overheat and the poly melts and the connectors short together.

In the case of boilers the supply should be in a continuous run of heat resisting cable from the plug or spur outlet to the boiler power inlet connector. At least that would be good practice!

[namsag]

I see you have learnt how to wire a boiler correctly now Agile as you used to wire them using non heat resistant cable because you didn`t know that .75mm heat resistant was readily avialable

as i understand it was not permitted but hey im only learning........... what if theres an escape of water

 

[doyle]

talked to raven heat about mfi specifications on the flue terminal against guttering (that flue guard business in understanding instructuions thread)
by all accounts what its attempting to define is less than one mtr then heat sheild must be unsed with clearance between flue and sheild of 25 mm. why they couldnt just print it that way i never know

 

[scatmanjohn]

as with scatmans serious looking frown

Its not a frown but a look of total confusion.

circuit board according to mfi.

I thought their expertise was with kitchens

I don't understand the question..sorry
