  1. I have no idea. You need to find out the requirements of the local council.

  2. I don’t think so, but, in any case, height restrictions are covered by local council requirements rather than the NBR.

  3. Graham Watters sê:

    Will the same height restrictions apply to a flue and a chimney?

  4. Hi Penny. I have a client who is building a new brick chimney with an internal clear space of 620mmx910mm. They would like to have a gas fireplace located inside their home which not positioned in the space in the chimney but on the side of the room with just the flue in the chimney, and a built in braai outside which would be installed on the outside face of the chimney and use 145mm space inside the chimney. Are there any restrictions around a ‘shared chimney’? If necessary the chimney can be separated into 2 and we would be able to build a wall to divide it. Would this be acceptable?

  5. Haai daar,

    What is the required and safe distance for a freestanding and built- in fireplace to be from wall power-outlets and switches?
    Thank you 😉

    How can I download a free copy of Part V from your website? The previous version would be fine – it has not changed, I’m told..

    Hallo Penny

    I am a trustee in a complex and one of the owners installed a anthracite (she claims) fire place without our approval or waited for our response whether she can install the fire place.

    Looking at the chimney it appears as a DIY job with incorrect procedures to ensure water proofing and avoiding to roof leaks.

    reading up on the above it can easily be questioned if the owner followed the SANS regulations and guidelines on installation.

    It also appears unsightly and poor workmanship with only water proofing and Membrane used around the steel chimney.

    Could you advise on this.

  8. Hi. Must you install double insulated chimney flues through a ceiling or can you insulate single flues with rock wool instead?

  9. Hi is a rocket mass heater or American Masonry Heater system legal in South Africa To build in a house, it is a highly efficient way to heat up a are

  10. Goeie dag,

    Where can I find information on the requirements/regulations of a spark arrestor?

  11. Hallo Penny

    Am I allowed to install my closed wood fireplace myself or must it be done by a certefied installer?

  12. Are there any specific regulations to adhere to regarding a gas fireplace with ceramic gas logs ? What must the surrounding housing be and insulated with if I do not want to build a brick wall? Can I have a mild steel structure , cladded with nutec board around it ?
    Or what is the safest option approved by South African regulation?

  13. I have been requested to solve a problem with 2 victorian fire places back to back in the same wall and when a fire is made in one fire place, the smoke billows out in the opposite fire place. The house has been built in the early 1900s and has been renovated recently. How would I go about rectifying the problem in the flue.

  14. Hi
    I recently had a cast iron closed combustion stove fitted in my lounge. The s/steel flue kit has a double, insulated continuous section for the entire distance from under rhinoboard ceiling to top of external “chimney”, where the cowl is fitted.(no joints)
    I agree with this as being a safe standard.
    In the event that I would install an “inside braai” as made by various suppliers off shelf, is the single skin rectangular (or round) ± 0,50 mm thick steel flue permissible in my ceiling space? These flues are mostly only etch-coat spray painted for “appearance value” ex factory.
    If these single skin flues are permissible, what are the closest measurements allowed from roof structural timber?
    Are slide-in joints permissible within the roof space?

  15. When galvanised steel is heated it becomes highly toxic and very dangerous. A chimney flue would normally be made of mild steel and would be about 3 mm thick.
    When you refer to this person as an “installer” what kind of qualification/recommendation does he have. Does he work for a reputable company? Certainly he hasn’t followed SABS or building regulation specs, or even good practise. You definitely need to take some sort of action, perhaps via the Consumer Protection Act.

  16. You are the person dealing with these so it is you who needs to approach the SABS for advice and further information. Not me!

  17. Lodge an objection with the local authority.

    Hi, recently we had an old defy rayburn heater installed. The installer kept the cement brick chimney with the old inner tube and only fitter a chimney from rayburn to the chimney. It looked and seemed fine, and it worked well, then the chimney turned a funny milky colour, we called the installer who told us he wasn’t sure and would come back to us, but he didn’t. Then yesterday evening the chimney collapsed and it nearly cost us our home but we managed to put the fire out in the rayburn. The next day we asked an independent person to come and have a look. He was shocked to see the chimney as it was made of galvanised steel 1mm thick and then funny colour was because of the toxic material burning. Is this true and where does one go to report if this installation is not correct and dangerous!

  19. Some advice please.

    My neighbour has submitted plans building an enclosed patio with an indoor braai.

    The chimney is on our boundary and the opening of the chimney will be at the same height as our 2nd floor deck and only 3m away. This small deck is our main entertainment space and comes off our lounge. Its a small cottage so that really is our only outside space. Is there anything we can do to have chimney moved away as its going to have a massive impact on us in terms of fumes, smoke and soot

    Hallo Penny,
    We sell slow combustion wood fireplaces with glass doors.
    The coldest place on the fireplace is right at the bottom.
    My question to you:
    1) Do you still need 500mm in front of the fireplace if the fireplace has a glass door ?
    2) Can we use 8mm Armourplate glass ?
    It seems to be very common in Europe to use armourplate glass.

    Hallo Penny

    Can i install a gas stove with a cast iorn wood stove in the same house – open plan kitchen and living room…


  22. Contact your local authority and ask them to send a building inspector or health inspector to look at the chimney. They are in a position to force your neighbour to make changes to the chimney if necessary.

  23. Madelein Kuther sê:

    Please assist with legality of a next door neighbour’s chimney. This chimney has a solid cover with 4 openings on the sides of the chimney. When a fire is lit, the cover or roof part of the chimney prohibits the smoke from going up an together with the wind it blows right into my house. This cause extreme health issues. What can I legally do?

  24. This has nothing to do with the National Building Regs. It is rather a matter of public nuisance. You can call your local authority for advice.

  25. What if you are in city area and live in duets what about smoke infringing on neighbours?

  26. Sorry Heather, not my area of expertise.

  27. I want to build an outside fire pit. Is there any specific building regulations on the distance from your house and neighbors?

  28. Francois van der Linde sê:


    Positive feedback. Owner of Company did site visit and will move the flues away from wood structures – he fully understood my concerns and committed to correct.


  29. Francois van der Linde sê:

    Hi, need some advice please. I had a wood burner (closed combustion type) (cast iron) installed recently and feel the installation is not safe. After query with installer they assured me it is safe but i’m not convinced.

    1.The problem is the stainless steel flue goes through roof and the flues are mounted with a metal bracket onto the wood rafters. The only seperation between flue and rafters is a piece of the ceiling board they cut out to accomodate flue through ceiling. In fact the flue touches rafters in two place and at ceiling exit in roof the flue touches wood batton.

    Is the acceptable ?

    regards Francois

  30. Hallo Penny,

    Experiencing a problem with a double sided fire place whereby smoke is coming back into the house. I’ve had a chimney sweeper out, who has cleaned out the chimney, yet the smoky problem still persists. Rotating cowl has been serviced.

    Anything ideas as to what could be causing the problem?

  31. Buti, Ceramic tiles are fired in a kiln and so are fireproof. So no you don’t need another material on top of them, providing the thickness is as stated in the regs.
    SANS 10400-1990 (I don’t have an earlier copy of the regs – but it’s unlikely to have changed) states that:
    – Every fireplace used for the burning of solid fuel shall have a hearth made of non-combustible material of adequate thickness
    – Such hearth shall extend not less than 500 mm in front of the grate or fire basket and not less than 300 mm beyond each side of such great or fire basket
    – No timber floor joist or trimmer or any other combustible material shall be built into any hearth.
    Note that this version of the regs can be downloaded from this site free.

  32. Hallo Penny

    If you have the ceramic tiles on the floor, would you still need another material on-top of the ceramic tiles to act as hearths or there is no need? Was this law relevent in 1988/ 1989?

    Thanking you inadvance.

  33. I thought the hearth is the material around the fire pot like for the wall unit. Thanks Penny for your response.

  34. Buti, While the word hearth is not defined in Part V of SANS 10400, Space heating, a hearth is simply the floor of the fireplace. In the case of the fireplace photograph on this page, the hearth is a tiled area of floor that complies completely with the regulations. viz:
    4.4 Hearths and fireplaces
    4.4.1 Every fireplace used for the burning of solid fuel shall have a hearth made of non-
    combustible material of adequate thickness.
    4.4.2 Such hearth shall extend not less than 500 mm in front of the grate or fire basket and not less than 300 mm beyond each side of such grate or fire basket.
    4.4.3 No timber floor joist or trimmer or any other combustible material shall be built into a hearth.”

  35. The good picture on this site for freestanding fireplace does not have hearth as stapulated in the SANS 10400-V: Space Heating regulation. How do you go around that? I want to install the same as it looks on the picture.

  36. Hi Joe,
    I see now what you meant. Thanks for pointing that out. It is done and the correct caption is now in the right place. Thanks again 🙂

  37. I think it does not refer to the actual order of the drawings but the descriptions/sub-titles of two of the pictures are different to the sub-titles used for the same pictures on the SANS document.

  38. We are not aiming to replicate SANS 10400; rather we are presenting information taken from the regulations. It is totally irrelevant which order the drawings are presented in!

  39. Please advise as the pictures & sub-titles on chimney installations on your website is turned-around if compared with the pictures in the 2010 government version on this section?

    Refer page 6 on the attached document compared to the website pictures under chimneys. Pictures for less than 10% roof pitch & opening adjacent structures are turned around compared to the original government file?

  40. This is not something that is covered by the building regulations.
