Re: Rangehood extraction into ceiling - question 9Aug 04, 2011 2:22 pm Ducting a rangehood into void spaces, ceiling or roof cavities is deemed a FIRE HAZARD. Correct venting of rangehoods is a legal requirement specified in AS1668 covering mechanical ventilation and requires “All exhaust air shall be discharged to the atmosphere”. Australian Standard, AS/NZS 4386.2:1996 Domestic Kitchen Assemblies refers. Cheers, Earl Re: Rangehood extraction into ceiling - question 10Aug 04, 2011 9:17 pm In WA most builders as a standard only duct kitchen rangehoods into the roof space, it is very unusual to find a builder here that automatically includes rangehood ducting to outside air. It is then up to the individual councils to advise whether they require external ducting for building approval, but roughly only half require it. The other half of the councils are happy to hand out a building licence with the rangehood only ducted into the roof space. I completely agree, it is a fire hazard and should be enforced.

Its law in VIC and building inspectors pick on on it. I have since found out it is not law in WA Re: Rangehood extraction into ceiling - question 12Aug 05, 2011 11:33 am Definitely should be vented to the exterior.

Rangehood extraction into ceiling - question 14Aug 05, 2011 1:07 pm newbuilder1 We asked our SS this yesterday as ours opens up into roof cavity. It is because if you have a tiled roof there is adequit ventillation in the roof cavity, but if it is a tin/colourbond roof it needs to be ventilated to outside. We have a colorbond roof but our kitchen exhaust just goes into the roof cavity.. Hmmm, interesting! Re: Rangehood extraction into ceiling - question 15Aug 05, 2011 1:18 pm Whether tile or steel - a kitchen exhaust fan (if not recirculating) should be vented to the exterior. There are other issues which are not covered under the reg's such as the ducting being able to be dismantled to remove grease build ups ( not that anyone periodically cleans the duct) & that it assists if the ducting is angled down towards the external vent point.

Re: Rangehood extraction into ceiling - question 16Aug 06, 2011 8:02 pm How Hard Can it Be Quote from Chrisandkate in the bathroom thread : (Hope you don't mind me copying it here Chrisandkate) It is illegal (in Vic at least) to have a rangehood ducted to the ceiling cavity. It MUST be dusted to atmosphere or recirculated though the house. If recirc is chosen you MUST fit charcoal filters to the rangehood. If you have built after this was past your builder has broken the law and should be made to fix it at their cost END QUOTE Anyway, so that seems to answer my question (we are in Vic). I will confirm tomorrow with building commission to get my own facts straight - but looks like another thing to add to the list . HHCIB Re: Rangehood extraction into ceiling - question 17Aug 08, 2011 7:16 am Well . . . that one got past me. Wonder what the case is if the roof is sarked ?

Re: Rangehood extraction into ceiling - question 18Aug 08, 2011 1:52 pm Well there seems to be some conflicting advice out there. I've listed on my 'defects' report just in case. I'll let you know outcome when the Building Commission come and inspect everything. HHCIB I use Tramex moisture meter and it will tell me instantly if the wall is cement sheet or plaster or masonite but most people dont have the equipment. 5 7086 the step up is 30mm and wanting it to be flat . how much does the concrete have to be lowered .we plan on removing bath and lenghten shower and adding seat. the old bath… 0 11835 8 6138 |
