Well i have asked a few friends and stupidly the engineer i asked should bloody raise it up etc and make it safe to work on and just bill me the extra.
Friends say you should not be touching and raising the oven yourself as u dont know how its connected to the gas(fixed connection or flexible tube?)
My firends also say, whats the point in phoning them then if they want u to do half the job yourself?
Another advice is that you should not DIY stuff in regards to gas as it can destroy a house/street.
NEVER DIY on gas appliances.
i know this thats why i want someone to bloody do the whole lot for me.
guess these lot can go jog off and i will find someone who will sort me out
