Flue Liner Repair

Flues and chimney systems are an integral part of an appliance's installation. Facilities Heating Maintenance Engineers understand how flues are constructed and the relevance of the materials that they must be manufactured from. Our engineers can successfully carry out flue liner repair and have the expertise and knowledge to facilitate this work.

As with all aspects of gas installation work, there are certain standards and regulations which must be adhered to. With respect to working on flues and chimney systems, there are rules laid out in British Standards (BS) and in the Gas Safety (Installation and Use) Regulations (GSIUR).

There are rules set out for the design, supply and installation of flue and chimney systems and for engineers and owners / landlords with regard to their maintenance.

Facilities Heating Maintenance recognise that it is essential that persons carrying out work on any flues for gas appliances are competent to do so and that each combustion appliances has been checked for:

  • Sufficient air for combustion purposes and where necessary for the cooling of the appliance
  • That appliances operate normally without the products of combustion (POC) causing a hazard to health (Flue Spillage)
  • That a device is fitted to warn of carbon monoxide where a fixed appliance is installed
  • That the appliance operates without causing damage to the fabric of the building through heat exposure
  • That the appliance and chimney/flue have been inspected and are fit for the purpose intended
  • That the chimney/flue has been labelled to indicate its performance capabilities.

The responsible person (e.g. owner / landlord) should be advised that, for continued efficient and safe operation of any gas appliance and its chimney, it is important that adequate and regular maintenance is carried out by a competent company such as Facilities Heating Maintenance in accordance with the appliance manufacturer's commendations.

The GSIUR impose a general obligation on owners / landlords who have gas fired appliances in premises to have them maintained and checked for safety every 12 months.

There are three main types of appliance, grouped according to how they discharge their POC:

Type A - Flueless - This type of appliance is not intended for connection to a flue or any device for evacuating the POC. This type of appliance is usually situated outside where products of combustion are released into the atmosphere and where the free air for combustion is naturally provided around the boiler .

Type B - Open-flued - This type of appliance is intended to be connected to a flue that evacuates the POC to the outside of the room containing the appliance. The air for combustion is taken from the room.

Type C - Room-sealed - The air supply, combustion chamber, heat exchanger and evacuation of POC (i.e. the combustion circuit) for this type of appliance is sealed with respect to the room in which the appliance is installed.
