Safety Precautions

  • Ensure your appliances are correctly installed and SERVICED ANNUALLY
  • Ensure that rooms in your home containing heating appliances are properly ventilated - NEVER BLOCK VENTS
  • Make sure all chimneys are regularly swept and kept clear
  • Use appliances only for the PURPOSE for which they were designed, e.g. do not use a cooker to heat a room
  • NEVER use any appliance if you suspect it might be faulty
  • If undertaking ALTERATIONS to your home which may affect the safety or efficiency of your heating installation (e.g. adding an extension, converting a garage, removing internal walls, changing a living room into a bedroom, double glazing / weather sealed doors) follow this safety advice:
    • Do not block or build around any existing air vents or flues
    • If creating a new living space, ensure it has ventilation in accordance with Building Regulations
    • If adding additional radiators ensure that your boiler can cope with the additional capacity
    • If you are altering or adding appliances to a natural gas or LPG installation, ensure that work is carried out to IS813:2002 Domestic Gas Installations
    • Get professional advice on ventilation and flueing before embarking on alterations to your house. Contact your fuel supplier for details of qualified personnel
  • Use Carbon Monoxide alarms but remember these are no substitute for regular inspection and maintenance of appliances, vents, flues and chimneys. Check that the Carbon Monoxide alarm complies with the EN 50291 standard.

Natural Gas

Choose room-sealed appliances. With room-sealed appliances fresh air intake for combustion comes from outside of the house and emissions are then discharged outside also. As such, the air in the room where the appliance is fitted is not used or affected by the appliance. Therefore room-sealed appliances (balanced flue or fanned draught types) are recommended for new and replacement boilers and water heaters.

Do you have an unsafe water heater?
Flueless gas water heaters are considered dangerous because they consume the air inside the room. This causes the products of combustion - including toxic Carbon Monoxide - to discharge directly into the room where the heater is fitted. If used for extended periods, the levels of Carbon Monoxide can build up to dangerous levels if there is a lack of ventilation. Open flue-type water heaters located in bathrooms are also considered unsafe. If you think you may have an unsafe gas waterheater contact Gas Networks Ireland now on 1850 79 79 79 for a free safety check.

Do you have a gas boiler which previously ran on oil?
In the past, existing oil boilers were modified to operate on natural gas. This was achieved by replacing the oil burner on the unit with a gas burner, with the old boiler casing and heat exchanger being retained. If you think you might have such an appliance contact Gas Networks Ireland on 1850 79 79 79 for a free safety check.

  • NEVER use any appliance if you suspect it might be faulty. Have it checked. If you require a safety check of your natural gas installation phone 1850 79 79 79.
  • For new installations or alterations to existing installation always use a Registered Gas Installer.
