Appliance converted from towns gas to natural gas?

[msemma]

An engineer recently told my mum that her freestanding gas cooker has problems because it had been converted from using towns gas to natural gas. the cooker isn't that old though, it was bought in the mid-90's, so is this likely to be true? the problems have been with the burners on the hobs, the grill and oven are ok. Anyone ever heard of this before ie appliances having been converted after production to accept a different form of gas?

I remember the conversion from town gas, it was in the 1970's, at least in Lancashire.

Sounds like complete rubbish to me - (or posssibly a mis-understanding).

As spudqueen says, natural gas began replacing town gas from 60's onwards.

Your average cooker from the 90's will be built and calibrated for natural gas. The only 'conversion' that goes on these days is for LPG, (generally used by those who want 'gas' but live in an area without mains gas.)

I agree with Brachiopod - -our last range type cooker had a conversion kit to enable it to run on LPG - the kit consisted of small replacement brass gas jets. They have a smaller bore to allow for the change in pressure. I would have a chat to a local 'Corgi' plumber/gas fitter.
