Converting LPG to Natural Gas

Here is a link to the manual https://www.yeomanstoves.co.uk/download/Gas%20Stoves/Exmoor%20Log%20Conventional%20Flue%20Installation%20&%20User%20Instructions.pdf I had a very quick read through it, on page 27 is states Changing between Gas types " A kit of parts is available for this - Contact your Gazco retailer for further information. " Typically when you get any gas appliance, cooker, fires they come ready for Natural Gas. If they can be converted to LPG there is normally a set of LPG injectors with the appliance. It is unusual to get an LPG appliance and convert it to Nat Gas. The instructions actually state the size of the injectors required As for the cost of getting a gas engineer in to convert it and then carry out the various tests, spillage, gas rate etc, I would assume somewhere between £60 and £100 depending where you live, how far the engineer needs to travel etc. The actual conversion kit shouldn't cost much, a few pounds at most and if you ask them nicely they may even send a pack out for free. You will need a copy of the manual at hand, the gas regulations forbid working on a gas appliance without it having a data badge and instruction manual. Without these the readings you get cannot be compared with the reading you should get.
