Replacing an existing unit
Note: I’ve never installed a gas cooktop, but how hard can it be?
I do have professional service experience and have a collection of tools and proper PPE.
Yet, none of that seemed to make it any easier. I was hoping for an easy replacement, but this one involved cutting tile countertop and all that super-easy stuff. Let’s tackle one step at a time.
Turn Off Gas
Turn off gas and remove power. Turn off breaker. Unplug stove.
Most cooktops are mounted and secured from underneath. Check inside the cabinet to determine what mounting hardware is supporting your existing cooktop. Carefully unscrew gas supply line.
Using the installation instructions provided with the cooktop, determine if the existing cutout will accept the new cooktop. In many cases, cooktops are a somewhat standard size and it may pop right in. However, in my case, I needed another 3/8″ of room on a tile countertop. I’ll share more below.
Take Your Time
Avoid costly and dangerous mistakes by taking your time, preparing your space, and wearing PPE.
- Plan your work
Go through each step in your mind before starting the job.
- Prepare your tools
Using step one, make sure you have the tools ready for each step.
- Get quality leak detector
Whether it’s a fancy service tool or quality bubble solution, don’t risk it with detergent or saliva.
- Check your work
Take the extra time to check, inspect, and test.
The Right Tools
I used a handheld power saw with a guide to get an accurate, straight cut through the tile countertip. Afterwards, I switched to an oscillating tool to carefully remove small sections and even out the corners.
Trim and Clean
Remember this area will be below the cooktop. I spent a little extra time trying to “make it pretty”, but the truth is that it will sit below the cooktop trim and will be out of sight.
Seal and Mount
Most cooktops include an adhesive seal. This seal acts as a barrier to prevent anything from getting underneath the cooktop. This was added to the border of the cutout in the image above (not pictured) before seating the cooktop on the countertop.
Our ‘On The Move’ collection features an assortment of common tools, installation hardware, and accessories to assist you with installation and maintenance.
Connect and Inspect
From the top-right corner, you see the regulator installed with the included pipe-thread sealant. Attached to the regulator is a gas supply line. There is not “standard” or “common” gas line size. Always refer to your installation manual for the proper size needed. An adapter may be necessary. Connect gas supply line to cutoff.
Do not use thread sealant on flared fittings, as it may affect the seal. It is recommended to use sealant only on threaded fittings. Make sure the sealant is for gas fittings.
Quality Leak Detector
Read All Instructions
Read and follow all included manufacturer instructions for best results.
Secure and Test
Following your installation manual and likely using manufacturer-provided hardware, mount the cooktop to the countertop or cabinet. Test your cooktop by igniting the burners and checking underneath for leaks. Use proper PPE and quality testing materials for any installation. If in doubt, contact a service professional in your area. Test or replace your smoke alarms regularly. Keep a fire-suppression product nearby.
