Plus openable window iirc

 

[mooey]

okay cheers it does nt mention that in the anwsers just says

130
70
180
145 which is what i ve got the next question adds on that you ve got a cooker in there and states it has an open able window but the vent size is different so looking in my anchient book says i need to add another 50 because of the room size is between 5 and under 10 so im going for
195 now
which is one of the options

You remember wrong. Openable window required for cooker not OF boiler. Room dimensions are not relevant for OF ventilation either.

ditto with the 'king of pop' ooo ooo

I ve got the questions right though.i said 145 for the 1st question which the ventaltion is worked out by the kw I did nt mention a window till the next question.which they add an oven so room dimensions become relavent hence needing to add 50cm and an openable window to the 45

 

[mooey]

Sorry that was suppose to be 145 not 45 doh

You dont add 50cm on for oven you go for the greater of total flueless or total open flue or largest individual requirement of any other appliance. 145cm would still be the vent size required.

You are right with permanent vent size, but we would also need an openable window or equivalent

 

[myles]

Yes, plus the 50cm if oven was only appliance would depend on if there was a door to outside
