If you order from Hardys of Kilkeel and tell them that you need a cooker to comply with Republic regulations, they will have the necessary devices added at the manufacture stage (flame failure) ( you may have to wait a little longer than usual for this).
I bought from Hardy's and got a qualified plumber to install it - no problems! If buying from a retailer in the South , still have to get it installed by someone who knows what they are doing!
