Hi everyone,
I have a disused chimney/flue which, whilst blocked off (vented) at the bottom, has an open pot at the top. I have been advised that this could allow rain (and animal) ingress thus I thought I would take advantage of my next door neighbour having scaffolding up to wander up there to fit a suitable cap. The one I had in mind is the 'C-Cap' for £20 as detailed at:
My main question however is that relating to a suitable cowl for my lounge chimney which currently has a living flame gas fire (Valor Urban) installed. Given I'll be up on the roof I thought I may as well fit another cowl for minimising rain ingress into this flue and it is my understanding that the difference here (compared with a disusued chimney) is that whatever cowl I fit must be able to cope with heat and allow sufficient draw. Thus I had my eye on the 'Brewer Birdguard' for £25 as detailed at:
I posed the question to the above site and they said that I should use the gas version as 'the finer mesh meets the gas regs'. This confused me as my pot currently has no cowl fitted (and thus no mesh at all) so howcome the larger mesh (solid fuel version) doesn't satisfy the regs? Or am I wrong to have inferred this?
If the solid fuel version is okay, would this be a better option given it would allow the gas fire to be replaced with a real fire at a later date without requiring the cowl to be replaced? My assumed drawbacks with this version however is that the larger mesh may not be as good at keeping birds/leaves out...
I would welcome any advice on this issue - feel free to ignore my specific questions and merely recommend the cowl(s) I should get. I primarily chose the above two based on cost (i.e. cheapest!) and them appearing to be 'fit for purpose'.
Cheers,
Mathew
