Ceramic Hob Glass Adhesive Seal Strip This hob glass seal creates a bond between your hob and the kitchen's work surface

Product Information

In short, yes, you can fit a gas hob into a worktop or similar yourself, however, this does not include connecting it up. Only a competant person with the correct testing equipment is allowed to do that! Nothing should be fitted in this “Hot Zone”. This includes any plugs, kitchen units or anything else that could burn or melt. We used the seal that came with the hob. You fix it to the underside of the glass hob and it works as a cushion for the glass hob. This should be sufficient to fit a standard 600 mm wide hob so will be approximately 2300 mm in length.

While applying grout sealer isn’t difficult, it can be a bit tedious if you have a large area to cover. Still, it shouldn’t take more than a couple of hours at most to finish the task. Always read the specific product application directions before applying sealer, but as a general guideline this is how the job is done. Having said that, I cooked a three-pan meal on the hob last night and throughout the chassis was cold and the stainless cover only got warm (the oven is not in yet). At least on this hob there's very little coupling between the top cover and chassis/flange and plenty of air movement. I was curious how hot my silicone would get. Not very hot it seems. Worktops are stone which would help keep things cool.The reason/reasons silicon should not used to set down ceramic hobs is because of the possible heat generated

It must be noted here that although a DIY enthusiast, or even a carpenter is allowed to fit a gas hob into a worktop or base unit, they are not allowed to connect it to the gas. Please see our project on gas safety and DIY installations. A silicone sealant cannot be used in the installation process of the B12 hob. Only the sealing strip can be used. The strip has to go on the edge of the appliance, then trim the excess off, very gently, as not to scratch the hob or work surface." Yes I agree, it's easy to lift but would a service engineer be willing to break the seal and cause possible damage, no matter how remote that it would happen. which silicon is not really designed for. Secondly, and this might include some sink units, the bottom edge of the fitment is thin, and the weight of the fitment on fresh silicon(moreso if screwed down) would tend to pull the fitment right down to the worktop, thus destroying the intended seal. Officially Gas Safe Register disapprove of silicone because the hob can not then be easily removed for maintenance. It must also be fixed using the manufacturer's clamps.I wouldn't have thought it would be all that difficult to prise polished metal away from sealant, though.

Essentially this is all common sense; you want it away from any draughts that might blow out the flame leaving gas flowing into your kitchen. I just fitted a ceramic hob into a new worktop, and the only sealing supplied was a very narrow adhesive foam strip. It is far smaller than the recess on the underside of the edge of the hob. This is just a guess, I would think the reason they say do not use a sealant, just in case anything goes wrong with the hob and it needs to be taken out. A gas hob is cut into a worktop and sits over a kitchen base unit like the one in the image above. Before it is cut you need to measure the hob itself, or use the manufacturers fitting instructions and/or template to make sure you know the exact opening size to cut. With the above in mind, any gas appliance needs to be connected up by a “competent person” e.g. a Gas Safe engineer that will perform a gas pressure test. The test in question tests the gas pressure before and after connecting up to ensure they are the same and if not, may indicate the presance of a leak.A very common size is 600mm wide by 500mm deep. The size of the hole you will need to cut into your worktop will be smaller than the overall hob size. Any gas hob needs to be fitted into a room with adequate ventilation, just in case there is a gas leak – a very unlikely event but potentially catastrophic. If there is not a door or window to the outside in the kitchen a gas hob should not be used. Having measured the hob the correct cut out size must be transferred to the worktop. Mark this with a pencil then use some masking tape to form a clear edge to cut to.
