Flue inspection hatches..

[3083sam]

Hi,
Where is the best place to get the fire resistant inspection hatches for flues??

 

[grahamgas]

They do 360 square hatches on BES.

Regarding the fire resistance requirement of inspection panels.

My take on TB008 Edition 2. I believe it deals primarily with Open and twin flue systems and doesn't deal adequately with flues from condensing boilers running in existing ducting.

Also, why use an inspection panel with one hour fire resistance fitted into an existing plasterboard and timber construction?

I make you right there mountainman , more rubbish :rolleyes2:

 

[mountainman]

I've made some enquiries and spoke to a really helpful Gas Safe inspector regarding my own quite specific concern.

It seems that common sense prevails when dealing with an existing enclosed FF flue within a single room (a kitchen in my case). Inspection panels are still required but they don't have to be of one hour fire resistance.

Seems to me that if in doubt, phone gas safe, they have gone well up in my estimation!!

I hear what you are saying but suspect the fire brigade are also the other people to clarify whats what as to how these access panels could transfer smoke and fire through these voids which I am sure gas safe have taken into account

the fire rating will depend on the route of the flue and the building construction. Building regs requires (not so much gas regs) anybody who runs something through a wall or structure must keep the fire rating of the wall in tact. So in theroy if you drill a hole through a 1hour fire rated wall then you must ensure that it still has a 1 hour fire rating after the work is completed, a 4 hour ceiling must meet a 4 hour fire rating after your works finished etc.... etc.....

most of the type i have seen are plastic

 

[ambrosia]

was sent to a job

5 flats in a listed georgian building, all the flues are vertical as per planning permission

All the flues go up through the flat above via ducting (except for the top flat of course)

whats the chances of having access all to 5 flats at the same time to inspect theses a access panels:rant:

It took me a week to get access to put CO alarms in

I tried to explain to my boss putting in the alarms make it legal for now, however next year it wont be
but i'm sure he didnt understand

I have fitted plastic vents to about 10 flats with concealed flues through suspended ceilings, concrete floors above so no need for fire resistant hatches.

If the truth be known, cutting inspection panels in ductwork passing through flats above probably causes more risks.

Going to be a bit of a logistical nightmare, but you will need to plan it to get everyone in on same day so you can inspect the full flue run.
Glad its not me.:tongue:
