Ventilation requirements for two dfe fires in one room

[FiremanT]

Couldn't find any info on flame reversal Steel, always glad to learn new things, and what's the mention in the regs please.

There was I think, a TB on flue reversal caused by upstairs ventilation. Or out mnay just have been an article in the mag

Your homework for tonight is to trawl through those regs to find it so you won't forget next time ..... Just think of it as sitting in class doing your ACS

Come on, don't be a sod; at least point me in the right direction.

Does any one know the required position on vents if a room has two dfe fires in it. I know the kilowatt rating is needed for the size of the vents its just the position I could do to know. Is for my NVQ level 3. Or if someone could point me in the direction of were I could find this information. Couldn't see anything in the viper book about this.

also remember the advantageous air is to be considered . some homework for you , how much advantageous air do you consider for the fires in your room ??
a bit of revision for you

 

[jeff the gasman]

100CM per fire, you are allowed no advantitious air so you ad 35CM for that.
Total is 235CM.

and if the DFE's are over 20kw?

 

[alan999]

In certain circumstances it can be relevant to consider whether the room was originally 2 rooms knocked into one for ventilation purposes.

Not with DFEs.

 

[gas112]

From the CORGI book
2 dfe under 20kw in one room normally 200cm or as per MI plus 35cm
2 dfe under 20kw in a through room normally 200cm or as per MI`S

Take the window out.
5CM per KW input plus 35CM I would go for.

Corgi do not exclude dfe's Jeff in their information about multi-appliance ventilation
