Heating Engineer (Has GSR)
Hi All
Hope someone can help, I have been asked to fit a new cooker hood that is to be vented to the outside and will come out directly opposite from the neighbours flue outlet which is approx 1000mm away , would this require a plume kit to divert the flue and if so does this need to be fitted by a GSR engineer, I have told the customer I am not happy to continue without advise, thanks.
 
Yes and yes it would need a gas safe eng to fit but depending on age of boiler they might not make one and then your in the poo, can't you vent the hood to a different place ???
 
Thanks for the reply, thought this would be the case, I cant vent hood elsewhere as it needs to go straight through the wall, will need to get the details of boiler and pass them onto a GSR .

I hope the neighbours are on good terms. I assume your customer will be paying for the flume kit (if available) to be fitted to neighbours boiler ?
 
I don't think there is anything in the instructions for ducted cooker hoods that says you can't fit where you want. And I can't find anything that says a flue over 600 mm away has to be moved.
 
My customer is happy to pay, just need to confirm distance from flue to new vent as I am only going on what they have told me and go from there.
 
Why not lift the extract hood up vertically on the outside with suitable ducting.

It'll be cheaper
It'll save hassle with the neighbour
And it will stop the nuisense of the extract discharge onto the neighbour's property.

Thanks for the suggestion , Ill run that past the customer. Customer has just sent me a very bad picture but looks like existing flue may be to close to the boundary so may be the neighbours problem, will check measurements tomorrow.

distance from opening/terminal across is 1200mm

Not the cooker hoods problem

Surely if its not allowed to put a flue within 1200 of a cooker hood for safety reasons then it would be common sense not to fit the cooker hood within 1200 of the already fitted flue, I certainly wont be doing it..
 
Alex, I know the term to term but where does the 2000 come from?

Building regs dimensions are used in the M.Is, so I would go with them.
B.S is a recommendation only.
Sorry the 2m is a recommendation is what I meant
