Gas appliances, gas installations

The gas appliance is an installation or system of structures used for the production, processing, transmission, storage, use, or filling of gas, including a natural, liquefied, biogas or industrial gas tank, pipeline, terminal, filling station, filling station, filling station or gas station.

A gas installation is a permanently installed operational system of gas pipelines and associated buildings. It also includes safety, control, instrumentation, and regulating equipment installed on the gas installation.

Market surveillance of gas appliances

Gas appliances on the market must not endanger persons' health and safety, provided that they are properly manufactured and installed, regularly maintained following the manufacturer's instructions, and used for their intended purpose.

The manufacturer or the person who places the gas appliances on the market must ensure that the gas appliances placed on the market are safe and comply with the Product Conformity Act's requirements and subordinate acts.

The Consumer Protection and Technical Regulatory Authority is competent to suspend the distribution and use of potentially dangerous gas appliances placed on the market for the time necessary to verify their conformity. If the expert assessment shows that the gas appliance does not comply with the requirements, the Consumer Protection and Technical Regulatory Authority has the right to order the withdrawal of the gas appliance from the market.

Requirements for installation and maintenance

Gasworks are considered the design, manufacture, construction, installation, dismantling, adjustment, testing, and repair of a gas appliance or gas installation, including filling a gas cavity and gas storage.

Gasworks may be carried out by a company registered in the register of economic activities as a gas works operator, provided that there is a person responsible for gas works and that the person is competent to do so.

The gas installation owner must ensure that a registered company carries out the gas work and that the maintenance of the gas installation is carried out at the frequency specified by the manufacturer.

The flue pipe of the gas heater must be cleaned at least once a year. The flue stack may only be cleaned by a qualified chimney sweep, who will issue the owner with a cleaning report stating the work carried out, the defects found, and, if necessary, proposals for remedial action.

Labeling of gas appliances

All gas appliances placed on the market must be equipped with:

  • technical instructions in Estonian for the installer
  • instructions for use and maintenance in Estonian for the user
  • appropriate warning labels in Estonian, which must also appear on the packaging
  • the conformity marking (CE marking)

The technical instructions intended for the installer must include all necessary installation, adjustment, and maintenance instructions to ensure that these operations are carried out correctly and that the gas appliance is used safely.

Technical instructions must include:

  • the type of fuel gas to be used
  • the pressure of the fuel gas to be used
  • amount of fresh air required for combustion
  • the amount of fresh air to be supplied for combustion
  • the quantity of fresh air necessary to prevent the formation of unburned fuel gas mixtures in dangerous quantities, unless the appliance is equipped with a special device
  • conditions for the dispersion of combustion products
  • the characteristics of the forced draught burner and of the heater intended to be fitted with such a forced draught burner, and the assembly requirements to facilitate compliance with the requirements for the complete gas appliance and, where appropriate, a list of the combinations recommended by the manufacturer

Where the manufacturer specifies no ventilation requirements, gas appliances may be installed in normally ventilated spaces without applying additional measures, provided that the total capacity of the appliances is less than 0,25 kW/m3.

The instructions for use and maintenance intended for the user shall contain all the information necessary to ensure the appliance's safe use. Particular attention shall be paid to the operating restrictions.

Conformity or CE marking:

The conformity mark is the manufacturer's or importer's guarantee that the product meets all the essential safety requirements for gas appliances and, where applicable, other safety requirements.

The conformity marking and its particulars shall be affixed visibly, legibly, and indelibly to the gas appliance or a data plate attached.

Where appropriate, the conformity marking may be accompanied by any information necessary to install the gas appliance.

The market surveillance authority shall have the right to request a written declaration of conformity issued by the gas appliance manufacturer and a written certificate of conformity issued by an approved body.

Matching mark details:

  • the conformity mark must be followed by the registration number of the notified body involved in the product checks.
  • the name of the manufacturer or an identification mark
  • the name of the gas appliance
  • where appropriate, the type of electrical supply
  • the category of the gas appliance
  • the last two digits of the year of affixing of the mark of conformity
