fitting cooker hood
I will be fitting a cooker hood (not done one before). I guess it will
be one with a squarish brushed metal riser. Some questions: 1. Is the fan usually integrated into the hood, or is it above the hood in the riser, or in the ceiling ? 2. The first stage will be to fit the ducting into the ceiling so the ceiling can be plastered up etc. There will basically be a stub of pipe sticking downwards out of the ceiling. When you later come to fit the hood and riser, how much tolerance do you get left or right to position it ? For example, assuming a flexible pipe is used for part of the connection, you could move the duct left or right by about inside riser width - outside duct width / 2. Cheers, Simon. |

Usually connected by a flexible connector, the sheet metal riser is just a cover. An inch each way should be about right. -- Dave - The Medway Handyman www.medwayhandyman.co.uk |

Usually connected by a flexible connector, the sheet metal riser is just a cover. An inch each way should be about right. Is it not usual to have an elbow straight out through the wall, rather than going up into the ceiling void? The reason I ask is that I intend to fit a cooker hood, but there is a joist running parallel to the wall in the ceiling directly above the hob location. Probably occupies a 3" strip of space from the wall IYSWIM. Phil |

Extractor hoods should use 5 inch ducting so you do have a few inches either side to move your pipe. -- Adam |

Others, especially with triangular hoods the gubbins will usually be within the triangle as you look If you have the resources (incl. time), consider "remotely sited fans" that lead back to just the grease filters above your hob etc - mucho quiet even on high speeds. De dietrich (and others I am sure) did some when I last looked into this 10yrs ago - gasp!! Some ordinary yet expensive "designer" hoods I've seen n heard at friends houses are not used even on the lowest settings cos of the racket/vibration/embarassment caused (unless absolutely necessary....)

Extractor hoods should use 5 inch ducting so you do have a few inches either side to move your pipe. I briefly considered ducting the output from the cooker hood on my wife's flat (rented out now). The fan is mounted in the hood and outputs vertically through a stub of duct, probably 5" x 5" as you mention. Plenty of space along the top of the kitchen units but a concrete lintel prohibiting access through the cavity wall. 4" duct and drop down the wall in rectangular section to an existing vent was do-able but never happened. Oh well! See how the mould goes this winter:-( One obstacle was adapting the 5x5 to 4" round. regards -- Tim Lamb |

De dietrich (and others I am sure) did some when I last looked into this *10yrs ago - gasp!! Thats what I really wanted, since I had an idea to include some kind of flap such that at single fan could either drive the cooker hood or an extractor grill in the ceiling. So it could be used to pull out hot air gathered by the ceiling in summer (inside ceiling slopes up from 8 foot to 10 foot). Access to the fan for maintenance might be interesting though. The fan would be in a small loft area in a single storey extension ceiling ! Simon. |

Simon. could you maybe mount the fan(s) outside? stick a velux or two in the roof - left open on "vent" in summer? stand on a chair you can reach 10ft...... Cheers Jim K |
