Built-in gas oven: a complete guide 2025

The built-in gas oven is a classic and still highly appreciated solution for those who love traditional cooking.
It works with methane gas or LPG , offers more moist cooking than electric ones, is economical in consumption and easy to install - as long as the operation is carried out by a qualified technician DM 37/08 .
It requires minimal periodic maintenance and guarantees consistent performance over the years, especially in Italian-made models such as Lofra or Silverline , which are more robust in construction than the basic models offered by chains such as IKEA .

What is a built-in gas oven and how does it work?

A built-in gas oven is an appliance designed to be integrated into kitchen cabinets , powered by a gas source.
The operating principle is simple:

The burner distributes the gas inside the cooking chamber.

Electric or piezoelectric ignition starts the flame.

The thermostat regulates the internal temperature.

A safety thermocouple interrupts the flow in case of accidental flame extinction.

This system allows for more natural and moist cooking, ideal for bread, pizza and roasts, where the open flame creates a more “artisanal” heat distribution compared to electric fan-assisted models.

What types of gas does it work with?

Most built-in gas ovens can operate with:

• Natural Gas (CH₄) – connected to the urban network.

• LPG gas (propane or butane) – via cylinders or tanks.

Many models are convertible thanks to a nozzle/injector kit that adapts the gas flow rate and operating pressure.
👉 The conversion should only be performed by a certified technician , to ensure safety and optimal performance.

Who installs the gas oven and what rules to follow

Installation cannot be DIY .
In Italy it must be carried out by a company authorised according to Ministerial Decree 37/08 , respecting the UNI 7129 standard which regulates gas systems for domestic use.

Key steps:

1. Check the kitchen area : adequate ventilation and aeration.

2. Check the gas system and the connection pipe (stainless steel or certified flexible).

3. Installing the oven in a niche with ventilation space.

4. Leak test and flame adjustment .

5. Issuing of the Declaration of Conformity (Di.Co.) , required by law.

📜 Without the Di.Co. the system is not considered compliant , and the manufacturer can refuse the warranty.

Advantages of the gas oven

Although electric models are more widespread today, gas retains significant advantages:

Cleaning and routine maintenance

A well-maintained gas oven lasts for decades.
Here's what to do:

After each cooking

• Clean the internal chamber with a damp cloth and neutral detergent.

• Wash grills and drip trays with hot, degreasing water.

• Dry the surfaces thoroughly to avoid corrosion.

Every 2–4 weeks

• Deep cleaning: burner, injectors, internal walls and door glass.

• Visual inspection of the seals.

Every year (by a qualified technician)

• Check combustion and tightness of fittings .

• Thermocouple, igniter and pilot light check.

• Replacement of worn components.

Construction Differences: Italian Brands vs. IKEA

The build quality of a gas oven can vary greatly.
Here is the comparison between specialized Italian brands and IKEA models :

🔸 Lofra and Silverline

• Production focused on gas cooking appliances .

• Heavy steel structure, high resistance enamelled chamber.

• Interchangeable methane/LPG nozzles as standard.

• Direct technical assistance and easily available spare parts.

• Design and materials designed to last for decades.

🔹 IKEA

• Line focused on built-in electric ovens , compatible with furniture.

• Lighter structure, designed for large-scale distribution, with attention to integrated usability.

• Excellent for those looking for functionality and integration , less so for those who prefer traditional gas cooking .

• Competitive price, but standardized assistance and fewer specific spare parts.

👉 In summary:

• If you are looking for performance, solidity and traditional cooking , focus on Italian brands like Lofra or dedicated Silverline lines.

• If you're looking for integration and simplicity , IKEA electric ovens are a functional choice but aren't as good as mid-range/high-end gas models in terms of construction and performance.

Installation Checklist

Choose the oven compatible with methane gas or LPG.

Make sure the niche has rear ventilation.

Make sure that the gas system is UNI 7129 certified .

Trust a technician qualified under DM 37/08 .

Always ask for the Declaration of Conformity .

Perform an annual safety and performance check .

❓ FAQ – Frequently Asked Questions

1. Can I install a gas oven myself?

No. In Italy, the intervention of a qualified installer pursuant to Ministerial Decree 37/08 is mandatory, who must issue the Declaration of Conformity .

2. Does a gas oven consume less energy than an electric one?

Yes, for the same use a gas oven consumes less energy and running costs are lower, especially if methane gas is used.

3. Do you need a chimney?

No, but the ventilation of the room must comply with the requirements of UNI 7129 to ensure safety and air exchange.

4. Can I use the same oven with LPG and methane?

Yes, if the model is convertible and the appropriate nozzle kits are fitted.
The operation must be carried out by a qualified technician.

5. How often should it be cleaned?

After each use, a light clean; once a month, a deep clean; and once a year, a complete technical check.

6. What is the difference between a Lofra oven and an IKEA one?

Lofra builds medium-high range gas ovens , with metal components and durability for intensive use.
IKEA offers electric ovens built into its furniture, which are practical and convenient but not designed for gas cooking.
