When to install Seperate Air fee for a Stove/Fire

selfbuild

Hi,
I am beginning to build. I wish to put in a stove in my kitchen, i intend to install its own air feed.

When should i install the air feed? and how?

Thanks

You have to talk to your civil engineer/architect about the issue.
Usually the air duct is running under the slab, depending where the furnace would be placed. What in turn usually depends on the chimney position.

In principle the duct should be kept short and without bends or as little as possible.
Contact your designer about regulations like water ingress, risks of blocking the airflow, thermal bridging ect..

Agreed, talking to your engineer is probably the first port of call. I would imagine they may not know however. The stove supplier should know exactly what you need, some will have different recommendations. One told me steel pipe so it would be "heat resistant". Another seemingly more knowledgable one said wavin up to the base of the stove, then a flexihose which comes with the stove will take it the rest of the way in. That is what I`m going with.

Pipe should be under the slab, so it will be installed alongside the floor insulation. You`ll need to know what side of the stove your air take is at also.

Generally is a 4" pipe too ...

It helps to know the stove you are purchasing (or have it bought). I was in the same situation as you and before my slab was poured I enquired about various different stoves but given the expense and short amount of time involved I couldn't decide to buy one prior to the slab being poured so I chose to install a 4" duct from the base of my chimney to outside prior to the pour which now incases it. When I buy the stove I'll engineer some connection solution to it if it requires its own air supply, if not then I'll block the duct.
