Me Chimley Pot

[amfisted]

Just a question about chimney pots.

I have a living flame gas fire in my front lounge (its about as much use as a set of wheels on a can of beans, but that's another story). Whilst up on the roof securing a TV aerial to the stack I noted that the chimney pot serving this fire is open at the top, thus allowing rain into the flue. There's a lip around the top of the pot which looks to me as if it was designed to take an additional fitting, so would I be right in thinking that there's some kind of vented cap I can add to the pot to protect the flue from the weather whilst still allowing the gases to escape?

I've repaired the flaunching on the stack so would be very reluctant to change the pot itself.

Cheers.

Be very careful what you fit IF you`re going to use the gas fire best to get it decomissioned by a gas safe engineer

Thank you.

I want to carry on using the fire, so which, if any, cap would be permissible in that situation?

Elephants feet are for redundant vents and should not be fitted to gas vented flues.

As nige said a gas flue vent cap requires proper care in selection especially with living flame appliances.

Probably the Gc2 range.

Thank you. I quite fancy a crowned insert, simply for reasons of nostalgia; we had the crowned pots on our first house, thirty years ago.

So do those inserts just drop into the existing pot? Are they held on by gravity/ friction, or do they have to be fixed?

The gas fire currently seems to give off relatively little heat in proportion to the amount of gas it uses. Would the addition of a cap/ insert to an open pot be likely to improve the efficiency of the fire?

 

[Alastairreid]

Yes they slide into the existing pot their own weight holds them in place.

Living flame fires lose a lot of heat up the vent. cant see the terminal improving on that.

On reflection, if I'm unlikely to make the fire more efficient by the addition of an insert, I probably won't spend the money and instead leave things as they are.

Cheers all for your advice.
