Installing a gas oven: rules for installing a gas oven

Household gas is a dangerous substance, leakage can threaten health and even life. Therefore, the installation of the gas oven must be carried out professionally, in compliance with all safety requirements.

You will learn all about the regulatory requirements for the installation of the oven and its implementation from the article we have proposed. We have described in detail the procedure for installing this type of household equipment and connecting it to the gas supply. Here you will find valuable advice and a checklist of steps to be taken to check the tightness of the connection points.

Safety first

Domestic gas leakage is an extremely dangerous situation that can lead to serious poisoning, explosion, property damage and loss of life. This happens infrequently, and the cause of accidents is usually common - errors in connecting devices and violation of their operating conditions.

The set of rules and safety standards boils down to ensuring that all connections of gas pipes and devices are sealed, the number of such nodes must be minimized. Having studied the rules for installing gas household appliances, even a home craftsman can cope with this task.

In the course of work, it is necessary to follow the procedure for connecting the equipment, use suitable materials, and follow the instructions exactly. At the end of the work, all connections are checked. Compliance with the rules will allow you to get the desired result - a safely installed and connected gas oven.

When installing a do-it-yourself built-in gas oven, the most common violation is the use of a tee for a gas pipe to which the hob is already connected.

Inexperienced craftsmen believe that if it works with plumbing, then it will work for the gas supply system. The result is three joints that must be carefully sealed.

According to the rules, the connection of the oven and hob should be carried out separately, bringing its own pipe to each device. In this case, the number of connections will be reduced to two.

In practice, using a tee can be quite safe. As long as the threads are properly sealed, it doesn't really matter whether two connections are made when connected or three.

But this method contradicts the existing rules for installing a gas oven. If, during the check, a gas service representative discovers such a tee, the owners of an apartment or house face a perfectly legal fine.

Therefore, from the very beginning, it is necessary to take this point into account in order to connect the oven correctly. In addition, a dielectric gasket should be used and a shut-off valve should be provided for each gas consuming appliance.

Installation and connection procedure

The oven can be dependent, i.e. combined with the hob by a common control panel, or independent. The first is mounted under the stove and installed simultaneously with it, and for the second, you can choose almost any convenient place, not necessarily under the cooking surface or next to gas stove.

The connection procedure for both types of oven is practically the same. This requires:

• select and prepare an installation site;
• connect the device to the power supply;
• connect to the gas supply system;
• install in a niche or cabinet;
• check connections for leaks;
• test all functions of the device.

Before replacing the built-in gas oven, it must be unpacked and inspected to ensure that it has not been damaged by inaccurate transportation.

Then you should read the manufacturer's instructions. It contains useful information to help you take into account the specifics of this particular model in the installation and operation of the model.

For effective ventilation of the outer walls of the oven, the following clearances must be provided:

• from the rear wall of the niche - 50 mm;
• at the bottom - 100 mm;
• on the sides - 50 mm.

In practice, these dimensions are rarely observed. If your oven has a wall blower function, you don't have to worry about the ventilation gap. The clearance near the back of the device is usually sufficient. Before installation, the rear panel of the furniture niche is simply removed or holes are made in it for the corresponding communications.

The material from which the adjacent furniture is made must withstand heating up to 120 degrees. After the device is unpacked, you need to place it near the connection point, for example, by placing it on wooden blocks. This will make it easier to perform the necessary manipulations.

If you need power

Modern gas ovens are equipped with many additional features such as:

• electric ignition;
• fan;
• grill;
• electronic control, etc.

These useful devices require electricity to operate. To provide a connection from switchboard a three-core power cable is connected to the device, install an RCD at 16A (for devices with a power of more than 3.5 kW - at 32 A, but such indicators are typical for electrical cabinets), provide grounding of the device.

In some modern kitchens socket with grounding provided by the project and intended for an electric stove. It can be used to connect a gas oven. Before carrying out work, turn off the power supply, use a tool provided with an insulating cover, adhere to other safety rules.

Sometimes you have to connect the power cable to the oven yourself.

This simple operation is performed as follows:

1. Open the junction box (installed on the rear of the instrument).
2. Loosen the screws that secure the terminals.
3. Secure the wires of the power cable to the terminals.
4. Fix the connection by tightening the screws.
5. Close the box lid.

The exact connection diagram for the power cable is usually given in the instructions.

Safety rules prohibit the use of extension cords, double sockets, twists and other elements that may not withstand voltage, cause fire, short circuit, etc. The position of the cable should be such that it heats up no more than 70 degrees.

Connecting the device to the gas supply

At this stage, it is better to adhere to the rule "not sure - call the master". Mistakes and carelessness during the installation of the gas oven are unacceptable. A gas leak can cause a serious explosion. Inexperienced craftsmen should contact a gas service professional.

As mentioned, the oven requires a connection branch separate from the hob, on which a tap is installed so that the gas supply to the device can be interrupted. It is imperative to install a dielectric gasket, which will allow you to open the electrical network if voltage occurs on gas pipe.

A flexible bellows is used for the connection. gas hose or a metal pipe - copper or steel. A rigid connection is used if the oven is very close to the main line.

The hose is more convenient to use where the distance is greater or where it is more difficult to bring the pipe. The connection point is usually standard dimensions - a half-inch pipe with an external thread.

When using a hose, you must:

• make sure that it is not pinched, stretched and does not come into contact with elements that are moving;
• make only two connections - at the entrance to the oven and on the main gas pipe;
• be sure to install a dielectric gasket and a tap;
• use a segment no longer than 1.2 meters;
• do not build up the hose, it must be solid.

From a tool to seal the connection, gas wrenches and double-pipe pliers may be needed. As a sealant, you can use a FUM tape equipped with a fluoroplastic film intended for gas pipes.

A universal nylon cord impregnated with sealant will also work. A gasket must be inserted into the nut that secures the connection. Tighten the fasteners firmly, but be careful not to damage this gasket.

Some craftsmen use the old method - linseed thread with drying oil, but it is considered not very reliable. In any case, you need to take a product that is certified as intended specifically for gas pipes. It must be resistant to pressure drops, vibration, temperature changes, corrosion and other destructive factors.

The thread is wrapped three times with Teflon tape, then the connection is tightened until it stops. The connection must be tightened with a gas wrench. It is normal for some sealant to come out.

Other sealants must be used in accordance with the instructions. For example, the base for a nylon thread should be slightly rough. A smooth surface reduces adhesion, so it is treated first.

Leak test and completion of work

To ensure the tightness of the threaded connections, use a simple method. All joints are covered with soapy foam and gas is turned on. Foam will bubble at leaks. To eliminate the error, you need to re-seal and then check the result again.

After connecting to the gas pipe and power supply, you need to fix the oven in the mounting niche. This is usually done with four self-tapping screws, the details are described in the instructions. Then they check the operation of the device.

All films and stickers must be removed first. Then connect the oven to electricity, turn on the RCD. After that, open the tap on the gas pipe and light the oven. If the device works correctly, the installation can be considered complete.
