Basic beginners question.

My 1992 Puck came without a gas bottle.
What do I need to purchase?

Photos of gas fittings.

Thanks

4.5 or 7Kg calor gas.

We also have a 1992 puck and I struggle to fit two bottles in the locker. One 7Kg will last us a very long time, that's helped by doing our main cooking in the awning using a second bottle and a safari chef ll or two ring burner and grill.

That regulator looks like it's for a 7kg bottle

If this is your first time please be vigilant, disconnect battery and electric if it's plugged in, then connect gas bottle, leave the gas turned on at the isolation tap, tap should be in the cupboard next to the fridge with cooker off. After 10 or 15 minutes you should be able to confirm it's gas safe, if you think you smell gas turn gas off at bottle.

As the regulator is for Butane ( blue bottle ) that is what you need.
