we the great trained/experienced need to be careful when quoting regs and getting angry, the guy has asked for advice lets give some rather than pelters, he doesnt have the MI and says he wont touch, thats a good start for me, why should a 25yr old fire which was designed without a modern safety device be AR or ID? (its another arguement to say no appliance should have been allowed on the market without a safety device, but there are plenty of cookers still on sale without) Dannypipe by your own admission you dont have any competance in fires, so when you go for your HTR1 ACS you will learn all about old OF appliances without any safety device, piezzo ignition or any such thing, i have seen tons of old fires with fixed pilot which keeps blowing out leaving unburnt gas filling the living room, it simply needs a service and clean to get up and running again,
to the OP get the make and model and the MI's, follow closely and get all your safety checks done (slowly) and properly and learn well from the job, it sounds like a DFE so will prob need 100cm2 free air vent etc, let us know how you get on.
It sounds like the appliance should be listed as NCS, or possibly ID. Capped and labeled.
Danny why NCS or ID, if it is fitted as per design it is not NCS, if it isnt spilling it isnt ID, the OP has asked for some guidence on an appliance he isnt familiar with, it doesnt look as if you are very competant to advise him on fires with these comments, don't mean to upset you
i agree with all you have said KG except the sentence ive highlighted.
not having a thermocouple/flame supervision setup means its not been manufactured up to TODAYS CURRENT standard, ie Not to Current Standards, i would classify as NCS only, certainly not ID as danny suggested.
if i work on a hob in a flat that doesnt have an fsd i leave an ncs letter, even though i know it was manufactured b4 the new regs came into force regarding cookers/hobs in flats, same thing as the fire issue IMO
