I recently opened up the old chimney breast to insert a dual fuel range cooker, the builder ensured that it was all safe, but I now have a chimney opening and if I look up I can see daylight,

what do I need to do in order to: stop the rain and other flying debris coming down the chimney onto my cooking. I did not want to install an extractor fan as I really don't like them. I am aware that it needs to be heat resistant one side and weather resistant the other. Help I have read some other answers and so far I think that I have to put on a cowl at the top of the chimney but am unsure as to what to place at the opening of the chimney within the house.

Hi you need to put the right cowl on I suggest a elephants foot well that's what I call them they just let the chinmey breathe so it doesn't get damp especcialy If it is a old property .At the bottom of the chimney you need to put a register plat made of galvanised Steel so it want rot and the register plate needs a small vent for air flow to keep the chinmey dry hope this helps.

you need to have a debri plate fitted this will separate the kitchen from the chimney normally it should be made out of steel 1.5 mm if it is a aga or a solid fuel appliance of some sort it will have to have one to comply with document j building regs. a cowl can be fitted as well if it is an aga of some kind it shoul be lined with a slid fuel liner as well hope this helps

A builder will tell you anything is safe if you give him a cup of tea and a buscit. I bet he then said that you must install a carbon manoxide detector and exactly where to mount it ? Call a hetas regestered installer and get them to install it correctly and safely. you can not bodge thease things. yes it will cost money.

EtchinghamI would definitely get a second opinion on whether that has been correctly installed. The rules on flue liners/solid flues changed a couple of years ago and it doesn't sound like that is up to grade. At the very least it sounds he hasn't finished the job. I have had to do one of these for a while but from memory. The flue has to be solid now, there has be a cowl on the top of the flue to prevent ingress of obstructions, there should be a plate covering the rest of the chimney to stop fumes coming back down the chimney and poisoning you, there should be a plate at the bottom to close out the chimney, any other fire places that feed into that chimney should be blocked off. You need a HETAS registered installer to come and sign this off before you risk poisoning yourself
