Browse Forums Building A New House 1 Aug 12, 2009 6:32 pm What does "Inviolation of 4386.2.1996" mean? This is again regarding ventilation for my rangehood. And I had an email saying that they think it's inviolation of 4386.2.1996 I'd like a little bit more information about that before I speak to PD and builder about it tomorrow. Any help would be appreciated. thank you!!

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”. One should not simply duct the air inside the cabinet without a ducted system as illustrated in Australian Standard, AS/NZS 4386.2:1996 Domestic Kitchen Assemblies. It is everyone’s responsibility, DUTY OF CARE, ( architects, builders, developers and building inspectors etc… ) to see that rangehoods in kitchens are properly ducted either externally, by using a fire rated ducted system directly to the outside of the building or if using a recirculating rangehood to make sure that it has an internal ducted system which is fire rated, this is generally done through the front or side of the bulkhead. Re: URGENT: Inviolation of 4386.2.1996 - what does this mean? 3Aug 12, 2009 7:04 pm Hi overwhelmed Please come back and let us know what the specific problem is with the installation of your rangehood, once you've spoken to your builder. There's been much discussion on this forum previously about ducting of rangehoods so am sure others would be interested. Could be how it is ducted or even the materials used for the ducting that are an issue. Re: URGENT: Inviolation of 4386.2.1996 - what does this mean? 4Aug 12, 2009 8:12 pm I think it's in relation to our lack of ducting. We have a vent in our brick work which is 5m away from our canopy rangehood. There is no roof space because we're in a double storey house ...but there is a little bit of space between the kitchen ceiling and the floor for upstairs. I think the issue is with the lack of ducting from the rangehood to the external vent but I can't be sure. Those code numbers were from someone trying to help me, but those numbers don't mean anything without a description. Who would know what that building code/ regulation stands for? I just need some solid ammo/evidence to present my case to PD/SS tomorrow so that we get ducting done properly.

Thanks for this Camelia. I found this too but it's from a ducting specialist website...so I didn't know if it was all true or not.

Re: URGENT: Inviolation of 4386.2.1996 - what does this mean? 6Aug 13, 2009 11:31 am The code numbers are for an australian standard - full code is AS/NZS 4386.2:1996. The title of the standard is Domestic kitchen assemblies - Installation. You might be able to get access through a state or university library, or you can buy copies off of saiglobal.com but it costs about $70 for 24 pages. edit: Just noticed the first part is mentioned in the earlier post Re: URGENT: Inviolation of 4386.2.1996 - what does this mean? 7Aug 13, 2009 12:38 pm would be very interested to know what exactly is the standard, if it is a requirement of the law, then builders should comply. i am wonderinh why many builders don't take this issue seriously - i mean, those "independent inspections". even in the design of the house - the architecture part....... nh Re: URGENT: Inviolation of 4386.2.1996 - what does this mean? 8Aug 13, 2009 12:53 pm I paid for ducting from rangehood? from that extract it seems that the builder should have incorporated it in our tender... would really know what is the outcome of this Villina with Trend facade Sydney Re: URGENT: Inviolation of 4386.2.1996 - what does this mean? 9Aug 13, 2009 6:03 pm I've just been to the house and I am rapt. The sparkies were there laying cables etc and they did the ducting. It's their job apparently! The SS just returned my phone call from yesterday and I said that I had wanted to speak to him about the ducting for the rangehood and he quickly jumped in and reassured me that PD always just leave it to vent between the floors and that the fumes will find their way out the vent...blah blah blah..then I told him that it is actually against regulations to do that and to nvm as the sparkies have already done it . He was surprised. I'm shocked that he's surprised!!!! So lesson learnt and I hope that others have also learnt from my experience too. Will take pics tomorrow to show how it was done.

Re: URGENT: Inviolation of 4386.2.1996 - what does this mean? 11Aug 14, 2009 11:45 am hi beebob I really don't know the answer to that question...I hope that someone else can help you. Not all rangehoods have to be vented externally. What you can do is find out from the rangehood manufacturer about how it should be installed. Then if you go to your electricals appointment, maybe find out from them. Builders will try to get away with as much as they can and squeeze every cent out of you. It's all dependant on if you have a double/single storey house....if they are venting into the roof space and you have opted to have sarking...then you might have to cop the costs...etc. I hope you can get some answers.

Re: URGENT: Inviolation of 4386.2.1996 - what does this mean? 12Aug 14, 2009 11:54 am I have a double storey and will get sarking with the colorbond roof. what does sarking have to do with the range hood ducting? will call manufacturer Villina with Trend facade Sydney Re: URGENT: Inviolation of 4386.2.1996 - what does this mean? 13Aug 14, 2009 1:35 pm Hi Beebob, I work for an electricain, and pretty much any work that they do (or anything they supply) has to meet Australian standards... This means that when ever anything is quoted it should be quoted so that Australian Standards are met. If they do not meet these standards then things such as public liability insurance and the like will not cover them. Its like retailers selling baby goods.. they have to meet the Australian & New Zealand standards, and anyone caught selling a product that does not meet these standards can get into trouble!! I am not a lawyer or anything but this is my understanding of the standards... Hope that this helps.... But it is always helpful to double check everything and learn from other peoples experience!!! Re: URGENT: Inviolation of 4386.2.1996 - what does this mean? 14Aug 14, 2009 7:57 pm Beebob I have a double storey and will get sarking with the colorbond roof. what does sarking have to do with the range hood ducting? will call manufacturer I don't think sarking has anything to do with the rangehood in a double-storey house with the kitchen on the ground floor. When sarking is used in a tiled roof it reduces ventilation of the roof space. So what goes in the roof space (steam, grease) stays in the roof space. That is why rangehoods and bathroom exhaust fans should be ducted to the outside if a tiled roof has sarking. (It might be a requirement for all roofs now, did I see someone say that somewhere?) overwhelmed Just posting an update: I've just been to the house and I am rapt. The sparkies were there laying cables etc and they did the ducting. It's their job apparently! The SS just returned my phone call and I said that I had wanted to speak to him about the ducting for the rangehood and he quickly jumped in and reassured me that PD always just leave it to vent between the floors and that the fumes will find their way out the vent...blah blah blah..then I told him that it is actually against regulations to do that and to nvm as the sparkies have already done it .

This appears to be a copy and paste from your other threads about this matter, so I will repeat my response on one of those threads which appears to have been overlooked. Having recently had an exhaust fan replaced I was under the impression that sparkies only do the initial installation and wiring, roofing plumbers do the ducting. Our roofing plumber had to fix the roof vent that was originally incorrectly done by our builder. No wonder it seemed to work so inefficiently! I'm now wondering just which of the builder's tradesmen cobbled it together? overwhelmed Now that I've had a few hours to think it through....hehehe....it would seem that it might actually be an electrical related installation code rather than a building code...iykwim. So that is why the job was the electricians.....which I would never have thought of. I'm actually very very shocked that my SS was surprised that the electricians did it......I'm shocked that he said that PD just vent into the flooring cavity!!! So I'm now very very happy that the electricians have ducted it all the way to the vent in the brickwork. So, for everyone else who is in the build process....if you have a canopy rangehood it has to be vented to the atmosphere....your builder should supply a vent in the brickwork for a double storey house and it is part of the electricians job to hook up the ducting when they are doing the wiring for your house as the electricians will come back and install all your appliances during handover. We didn't get alot of info from the electricians who were wiring up the house today. They were frantically working and had the music cranked up and they swore quite a bit trying to line up the ducting with the vent. I was just sooo happy they were doing it....it really made my day!!! AS/NZS 4386.2:1996 is, as described in the link I gave and I think others also explained it, the Australian and New Zealand Standard for Domestic kitchen assemblies - Installation. Now I think about it, the electrician who installed our laundry fan did the whole job himself, however the ducting in that case was a flexible tube that came with the fan unit. It was a matter of cutting a hole in the wall or eave and attaching the end of the tube, making sure to follow the instructions not to bend the tube too much or too little. So with some appliances that come supplied with a duct I guess it's appropriate for the electrician to do the whole installation. For installations like a bathroom exhaust fan ducted out through the roof the appropriate tradesman is a roofing plumber. None of our exhaust fans worked correctly or efficiently when we moved in, it just doesn't seem to be a priority with builders to get them done right! Render your bathroom walls, two opinions versus the one, makes you wonder. 3 6062 thanks Chippy, i hope they have applied sealer but i am doubt to be honest, so i am gonna do this job after handover. 8 16269 I am building in claymore NSW and this is shown in the building envelope plan. … 0 10035 |
