Hi, welcome to Just Answer. My name is XXXXX XXXXX X look forward to helping you! The link below will take you to their website. If you can provide a model number of the oven, I can likely find you a manual.
Where am I likely to find the model number? The stove is a floor model with solid cook plates, and no obvious number plate.
Thankyou. I will respond as soon as possible
Well I have looked all around the oven door -over and under and inside, but cannot see a compliance plateof any sort. Guess it is on the back, and as the stove is built in to the cupboards ( although on the floor) we will not be looking at the back as we are elderly.
If you could just say if it is likely that you turn the oven switch on a little before the first heat mark which is 50', is it likely that is the proper thing to do?
I am very happy with your assistance - just wish I could do more to give you a clue other than the year around 1990.
