If there are no instructions the usual size of the hole is 25mm less (all round) than the actual size of the hob.

5 Metre Sealing Foam Strip for Cooker Hobs or Kitchen Sinks

There are guidelines for “internal” kitchens, where a gas hob is fitted. This can occur when, for example, a conservatory has been built over the external wall, making the kitchen internal. Tube grout sealers allow for precise control over the sealant as you work without need of a brush or rag. But since tubes usually don't contain a whole lot of product, they are best used for small projects or for touching up damaged spots. If you have grout, it's smart to keep a tube of sealant, like the Miracle Sealants Grout Sealer, on hand for spot repairs when needed. This helps to keep the grout intact over time. 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. There is a hot zone immediately above the cooker or hob where there should be nothing fixed, including extractor hood, for 760mm. Either side there is a zone of 150mm where there should be nothing fixed up to a height of 460mm. Extending to the rear, if fitted into a worktop you should leave 50mm.

Pencil marks are hard to follow when there is a lot of fine sawdust about. Additionally, don’t forget to wear a dust mask! Now you are ready to fit your new hob, although it is wise to have a good read of the appliance instructions before you start so that you are familiar with the measurements for your particular gas hob. Drill a 25mm hole inside the cut out area (more than one can be drilled if it makes life easier for you) and use a jig saw to cut out the hole required for the hob. If the sealer leaves any hazy or white splotches on the tile, dampen a clean cloth with a bit of the grout sealer, and wipe the area until the blotch is gone. Now wipe the tile with a clean, dry cloth to remove any lingering residue. I can see the reason for the general "don't silicone hobs" rule, but if used sparingly, why can't it replace the foam (as a water seal) and avoid the problem described above? I.e. where the cover won't sit flush because the clamps can't compress the foam and/or flex the chassis while trying.

When the hole is made its time to fit some clips to hold the gas hob in place. These clips should come with your hob. You can fit a gas hob yourself, and it is a very satisfying job, if you take the time to do it right. You are not allowed to connect the hob to the gas unless you are Gas Safe registered, and it is worth engaging with your chosen engineer before you start so that you are familiar all the rules. There are some simple guidelines to follow when it comes to where you shouldn’t place your gas hob: 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. 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.Formulated for both interior and exterior use, you can also use this sealer to protect outdoor tiled surfaces on patios or around swimming pools.

After he left I was getting it square and trying to remove the excess foam. I noticed the problem described above where the stainless cover wasn't sitting down onto the worktop. The clamps only have so much pull and they're on the corners and the chassis flexes against the foam. Apply enough grout sealer to soak the grout. Work slowly and methodically to ensure you evenly coat all grout surfaces. If the grout is new, wait at least 48 hours—72 is better—before applying grout sealer. This gives the fresh grout enough time to dry completely. Otherwise, you could get cloudy or bubbled results. For a gas hob you will need a gas supply – obviously! This must not be more than 1.5m away from the intended location of the appliance. Not sure if that makes sense. I may have completely missed the point about not using silicone but the hob sits nicely nowThere is no official standard size hob, and the number of rings can vary from 2 to 5 typically with will further affect the overall size of the hob. The clips are fitted to the underside of the hob and tightened onto the worktop to hold the hob firm. The hob should also sit on some sealing strips to keep the joint between the underside of the hob and the top of the worktop, clean and waterproof. Nothing should be fitted in this “Hot Zone”. This includes any plugs, kitchen units or anything else that could burn or melt. 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. 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.

I had my gas hob fitted today. The plumber was in a hurry and didn't get it square with the worktop and the foam was all over the place. Nice soldered joints though. The sealer is designed to repel oil and water, which can lead to extensive damage in the grout over time. In places where moisture is common, such as the kitchen or bathroom, this type of protection can reduce the amount of maintenance your grout and tiles will need after extensive use. The sealer helps repel food, grease, and mildew, as well as mold to prevent ugly stains and damage from developing. Like most grout sealers, this one is available in several container sizes, including spray bottles. Wipe excess sealer off the tiles, unless you are using a product meant to seal both grout and tile. 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! 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.Let the sealer dry for the time recommended by the manufacturer. This is typically anywhere from 15 minutes to an hour. If sealing old grout, be sure it’s as clean as possible before resealing it. Otherwise, you’ll trap dirt and stains beneath the sealer. Don’t assume that just because the gas hob or the connection hose is brand new that it can’t possibly leak. Defects can occur during manufacture and also things can get damaged during storage and transport. All gas hobs should come with detailed instructions about where they can be fitted and the safe distances that units, plugs and anything else, must be from the fitted hob. Read and follow these as they will be up to date and specific to your appliance. That said there are some general rules that you should follow: Ventilation
