How To Install A Gas Cooker? Our Easy Guide!

Installing a gas cooker is not very difficult. It helps to have some basic knowledge of how they work before you start, but if you are unsure just give your local specialist a call and ask them to come out and install the appliance for you. 

As you may know, gas cookers are very efficient appliances that run on gas. Each year, a number of people attempt to install their own gas cooker, but give up after a while. The main problem is the installation process is very complex and instructions are hard to follow.

Here are some instructions on how to do this yourself:

List of Required Tools

The following tools are needed for installing gas cookers:

  • a screwdriver
  • spanner wrench or pliers
  • socket
  • ratchet set

If you need to install the cooker over existing appliances then additional mounting brackets will be required as well.

4 Easy Step-by-Step Guide

Installing a gas cooker is a fairly easy and straight forward job, but take your time.

The easiest way to do it is in a garden, but if you have to do it indoors then cover the floor with newspaper and open windows to ventilate the room. You will also need to shut off the gas at the mains.

Mark the mounting position on your wall for brackets (e.g. with a pencil). This is where you will need to drill holes in order to mount the new gas cooker securely.

If necessary, use masking tape or sticky putty to protect any surfaces near this area from drilling dust and debris – such as tiles on your kitchen wall behind electric sockets.

1. Disconnect and remove the old

Remove your old gas cooker from its position by sliding out the appliance stand; in some cases this will be just one side that is connected on each end with screws and bolts.

If there’s anything underneath blocking your way take care not to damage pipes, otherwise remove any debris around the appliance connection points.

Disconnect the gas pipe by following its lead down to where it’s connected to the old gas cooker and then unscrew or unclamp this connection with a screwdriver.

If you have an electric ignition, disconnect power supply at mains before continuing. Remove any other cables that may be attached (such as water inlet).

Unscrew brackets on either side of your new gas cooker using these two screws supplied for each bracket – do not over tighten them; they should just pull through until tight enough to hold securely)

2. Wrap pipe line threads

Prepare area for installation by taping down plastic sheeting or cardboard over worktop surface – unless already protected when removing previous unit.

This should minimize mess as you’ll need to remove the plastic sheeting or cardboard and clean up any spillages as you go.

Wrap pipeline threads and screw securely in place. Make sure that the joint is sealed off by covering it with some plumber’s putty – this will ensure a watertight seal.

Tighten screws gradually but securely so that joints don’t leak any air otherwise you risk damaging your gas cooker as well as all of your house!

3. Attach the connector

Draw a level line to mark where your gas cooker will be positioned (usually about 100mm from front edge of worktop).

This is important for two reasons:

  • firstly, it means that when positioning the new appliance you’ll know how far back in relation to the old one.
  • Secondly, with this done you will now have an idea of how much pipe length needs to be removed before connecting your new unit – making installation easier.

Remove all piping connections off previous unit including pipes, flexes, unions.

Dispose of them carefully out of reach of children and pets because they’re made from copper which can cause severe health problems if ingested.

Cut the new copper pipe to length and, using a gas pipe cutter, make any necessary bends.

Fit unions on either end of each cut section then connect them together with a suitable brass or stainless steel connector (depending on whether you’re using 14mm or 22mm piping).

You’ll also need to fit an appropriate union at one end of your cooker’s flex – it should be as close as possible to where it connects into the appliance itself. This will allow for easier installation in future.

4. Reinstall the gas cooker

Reinstall the gas cooker at the same height as before.

Finally, attach all pipes onto your new unit following manufacturer instructions carefully before tightening securely with a spanner.

Tighten screws gradually but securely so that joints don’t leak any air otherwise you risk damaging your gas cooker as well as all of your house!

If necessary, attach wires to electrical kit according to instructions given – only if not already done before installing kitchen installation for safety reasons)

Check whether gas cooker connects correctly into pipework from where it was previously installed; amend with appropriate brackets if needed.

Carefully position gas cooker onto the refurbished stand from where it was previously installed. Clean around pipes and plugs to remove any residue that could prevent a tight connection* (ensure you have turned off power) Once complete: turn power back on to new gas stove.
