We are a Gas Safe registered company and are able to sign off gas fire installations of all types.
There are many different types of gas fire installation, ranging from open gas fires, to glass fronted sealed appliances with balanced flues, through to modern hole in the wall, or room dividing fires.
Gas fires can operate with natural gas, or LPG (Liquid Petroleum Gas), but they require engineers with the correct qualifications to sign them off. LPG has an additional qualification which enables the gas engineer to sign off installations of that type. This is due to LPG being heavier that air, and therefore will settle in the lowest possible location if leaked. Typically LPG fires are used in outdoor installations, or in remote locations where natural gas is not available.
Open gas fires are most peoples preference as they most resemble a solid fuel fire, when topped with some ceramic logs. It is important to note that open gas fires though are classed as DEF fires. This stands for Decorative Effect Fire, which basically means that they are for effect, rather than heat, as 80% of the heat will disappear up the flue. An open gas fire is made up of a gas burner, and something in which it sits. This can be a basket, a bowl or even just a raised hearth. Basically any gas fire where the flame is open to the room is classed as an open gas fire.
Glass fronted fires, or sealed appliances, are fires where the flame is completely sealed behind glass and therefore not burning oxygen from within the room in which it is located. The combustion air is drawn in through a ventilation pipe, which in most cases is within the flue itself. These are called balanced flue fires and the combustion air is drawn in through an inner pipe which runs through a larger pipe. This larger pipe (flue) carries the fumes/combusted air out of the building.
The Gas Safe Register is the official gas registration body for the United Kingdom, Isle of Man and Guernsey, appointed by the relevant Health and Safety Authority for each area. By law all gas engineers must be on the Gas Safe Register.>>>
Calculations to consider for an open gas fire:
– Typically gas fires over 6.9kw require at least 100cm square of free air into the room.
– Open gas fires should not be operated in rooms that can contain water. i.e. bathrooms and kitchens
Old Technology – Sand Kits
Gas fires that use a sand kit, where the gas passes through a bed of sand before being combusted are called Sand Kits. These fires are OK to use if they are already in use. This is until they go wrong. Then they must be replaced. This is because they do not meet current regulations, and therefore can not be signed off by a Gas Safe engineer. So currently an operation sand kit fire is being run ‘At Risk’. This means that it works, but that there could be a risk, and the the owner should be aware of the risks. Once they are disconnected for any reason, they can not be re-connected and signed off. Hence a new burner being required.
