LPG gas Injectors on a Cooker hob Help, advice and problem solutions on all aspects of home appliances from washing machines to TV's

[Calhoon]

I have had a new cooker delivered for LPG connection, along with a conversion kit for LPG use. However, for a number of reasons, I am not certain if the gas hob has already been modified with LPG injectors (with the natural gas injectors being put back into the kit pack) or not! Is there a way that I can identify which injectors are 'in place' so that I can change them over if necessary? ... I live in France, hence the confusion due to minimal regulation governing installations etc!
