Carbon Monoxide Kills
Every year about 30 people die in the UK from carbon monoxide poisoning caused by gas appliances and flues not being properly installed or checked regularly. Many more fall ill from this cause - don't let it happen to you or your tenants!
Gas Safety for Landlords and Home Owners
In 1996 the government made law that all landlords who rent part, or all of a property, must have all gas appliances and the pipe work installation checked and a certificate to prove it every 12 months.
If you are a landlord with your gas appliances unchecked, call us today for your Landlords Gas Safety Certificate (CP 12)

This service is also available for homeowners who wish to have their appliances safety checked for peace of mind or wish to show to show documented evidence to potential buyers that their gas appliances are in safe working order
What does a Landlord Gas Safety Inspection Include?
A City Gas Services CORGI registered engineer will check the following during a Landlord gas safety inspection:
Check appliance for gas tightness.
Check standing and working pressure if test points available.
Check burner pressure / gas rate against manufacturer’s data plate.
Check for satisfactory provision of all necessary ventilation.
Test flue flow to ensure removal of products of combustion.
Check satisfactory operation of all the flame failure devices.
Check for physical stability, presence and effectiveness of stability brackets (where appropriate).
Investigate any evidence of unsafe operation and report to a responsible person. An appliance can not be deemed as having been checked, until the above has been completed.
For a Landlords Safety Record inspection a tightness test of the full system should be added to the above.

Carbon Monoxide Detectors

Carbon monoxide is a highly poisonous gas with no taste, no colour and no smell. It can be produced when any fossil fuel such as coal, wood or natural gas is burned and there is not enough air supply.
Carbon monoxide kills up to 30 people each year and many more are seriously injured. It can escape into your home if a gas appliance is not installed correctly or serviced regularly.
Buy a carbon monoxide detector to detect this poisonous gas. As carbon monoxide (chemical formula 'CO') has no smell, taste or colour, it is important to have reliable carbon monoxide detectors installed. The Fire Angel carbon monoxide detectors give both a visual and audible warning if there is a build up of CO to dangerous levels.

Call us on 0800 075 8181 to have this life saving device installed in your house today.
Carbon Monoxide (CO)
Carbon monoxide (CO) is widely known as the silent killer. It is highly poisonous and cannot be detected by the senses. You can't see, smell or taste its presence. Exposure to even low levels of CO can cause brain damage and death.
CO is produced by the incomplete combustion of gas, solid or liquid fuels. It arises from badly installed or poorly maintained gas appliances. Insufficient ventilation to the appliance or away from the appliance (flues and chimneys blocked) will also cause CO build up.
Signs of CO are: yellow or brown stains around the appliance, pilot lights which blow out frequently and increased condensation inside windows.
Symptoms: Fatigue, headaches, flu like symptoms such as nausea, chest pains, sudden giddiness when standing up, sickness, diarrhea and stomach pains, erratic behaviour.
-
If you suspect CO: switch off appliance, open doors and windows, visit your GP and call a CORGI installer.

Using the latest Testo equipment city gas services are able to test appliances suspected of producing carbon monoxide.
It is very important to have any gas appliances serviced and checked once a year to prevent an appliance producing carbon monoxide.
If you have any concerns’ for carbon monoxide and would like your appliance tested for peace of mind call us today on 0800 075 8181

Gas Fires
We have been working in the fireplace industry for numerous years and therefore in the perfect position to advise you.
Remember buying a new fire is an important decision and we want to make sure you make the best decision possible. We have tried to include all the information you need to make a choice, however should you feel you need a personal touch or want more information, our highly skilled staff who are all fully conversant with the products will be happy to help with a personal reply, either by e-mail or telephone.
We stock a wide range of gas fires, Please call on 0800 075 8181 or use the contact form for a free brochure.
Types of Fires
Inset Gas Fires
This type of fire is recessed into the fireplace opening just like a traditional coal fire. Models are available to fit Class 1, Class 2 and Pre-cast flues. The depths of the fires vary considerably, the deepest only suitable to fit into a traditional brick built chimney. However, many models are suitable for installation into pre-cast flues. Most inset fires are open fronted although some incorporate a glass front panel to increase heat output and efficiency. Balanced flued versions of some models are available.
Outset Living Flame Gas Fires
This type of fire sits proud of the flue. It usually has living flames and a glass front to increase efficiency and will fit in Class 1, Class 2 and Pre-cast flues. Some fires can be wall mounted and therefore do not require a hearth or fireplace. Balanced flue versions of some models are available.
Radiant Gas Fires
The traditional gas fire with white radiants (ceramic pots). These are economical to run and very controllable. Most models can be hearth or wall mounted and they are suitable for Class 1, Class 2 and Pre-cast flues.
Balanced Flue Gas Fires
Can be installed in homes that do not have a flue of chimney. They are installed onto an outside wall and take their air for combustion and expel their products of combustion through a horizontal flue consisting of two concentric metal tubes. These fires always have a glass front and are sometimes called 'room sealed'. This type of fire is very efficient in operation and has lower running costs.
Outset and inset models are available. Inset models can be recessed into the inner leaf of a cavity wall, or special fireplaces can be constructed (a 'rebated' surround) to accommodate the inset depth of the fire.
Fan Flue Gas Fires
Similar to balanced flue fires in that they are installed on an outside wall. They are usually open fronted giving them a more realistic look. They are not room sealed and use air from the room for combustion and expel the products of combustion (fumes) to the outside using an integrated electrical fan. Some noise can be heard from the fan although this is minimal and most owners find a slight humming noise acceptable. Some versions of these fires use a longer tube to expel the products of combustion enabling them to be fitted on internal walls.

Flueless Gas Fires and Stoves
Flueless or 'catalytic' fires operate without a flue or outside wall. A catalytic converter inside the fire 'scrubs' the flue gasses (fumes) and removes all undesirable elements. All that emerges from the fire is carbon dioxide and water vapour. This type of fire is classed as 100% heat efficient as no heat escapes through the flue. Permanent ventilation must be installed in the room where the fire is sited (such as an air brick or floor vent of 100cm sq). An openable window or louver is also required in the room the appliance is to be installed into. The minimum sized room suitable for the use of a flueless fire is around 30-40 cubic metres depending on the model. 40 cubic metres is around the size of a 14ft by 14ft room or 30 cubic metres a 12ft by 12ft room.
Hole in the Wall fires
Some inset gas fires are designed to fit into a 'Hole in the Wall' situation rather than into a fireplace. Depending on manufacturers' instructions they can be fitted without a hearth. FFF recommends that a hearth be installed at floor level to maintain safety especially where children, the old or infirm have access to the fire.
Gas Stoves
Gas Stoves are constructed from cast iron or heavy gauge steel. All models have a glass windowed door, some models have double doors. They are available in conventional flue and balanced flue versions. The heat output is usually quite high, as is the heat efficiency. Flue pipes are not usually included with the stove and must be purchased separately.
Electric Fires and Stoves
The real benefit of Electric fires is that they require no specialist installation. Inset electric fires usually require some sort of recess to accommodate the back of the fire. This can be a fireplace opening or a specially designed fire place (see the Electric Firesuites product guide for details). Some models come with the option of a removable spacer frame that allows the fire to be used freestanding without the need to create a recess. Most fires have a 2kW fan heater hidden under the canopy of the fire, some even have thermostatic control. The flame effect on the fires are very convincing and supply a comforting flickering flame effect independently of the heating element.
Electric stoves have similar features to electric inset fires and are all freestanding. Their cast iron look is achieved by using a special paint coating.
Gas Wall Heaters
Wall heaters are an economical way of heating a home without central heating or as additional heat in cold areas such as stairs, landings and conservatories. They require a suitable outside wall through which passes a balanced flue approximately 6 inches in diameter. This flue pipe provides air for the gas to burn and expels the products of combustion (fumes) to the outside.
A CORGI registered installer should be consulted before ordering a wall heater to confirm that the desired installation location is suitable.
Types of Flues
Class 1 Flue
This is usually a brick chimney of a minimum internal diameter of 7 inches. This type of flue will usually accommodate any type of open flued gas fire. Be wary of chimneys that have previously has a gas back boiler and fire installed as they may have a 5 inch diameter flexible flue liner installed inside them (in effect making them a Class 2 flue).
Class 2 Flues
These flues are usually Class 1 flues (chimney) lined with a flexible flue liner of 5 inches diameter or 'twin wall' rigid metal flue pipes. A metal tube or terminal emerging from the roof can indicate the presence of a Class 2 flue.
Pre-Cast Flue
House builders began to install this type of flue in new houses in the 1970's in order to save the space that a chimney breast would occupy in the room. They are constructed from pre-cast concrete blocks that are built into the structure of the house. Due to the narrower depth and smaller cross-sectional area of the flue not all fires can be installed in this type of flue. Some pre-cast flues, usually in newer houses have a small 'chimney breast' that protrudes into the room 4 or 5 inches; others have no protrusion at all.
Balanced Flues and Fanned Flues
Balanced Flues go horizontally through the outside wall of the house. A balanced flue exits from the back of the gas fire and obtains its air for burning from the outside. It in turn expels the products of combustion (gas fumes) to the outside through the same flue. The balanced flue is manufactured as part of the gas fire and cannot be installed separately.
Fanned flues look similar in appearance to balanced flues but take their air for burning from the room in which they are installed. They use an electrically powered fan to expel the products of combustion horizontally to the outside. Some fanned flue fires are can be fitted on internal walls with flue pipes that run several metres to an outside wall and even around corners.
Fuels
Most gas fires are designed for use with Natural Gas (NG). Some are manufactured as or can be converted to use Liquefied Petroleum Gas (LPG or LP Gas) or bottled gas. Depending on the fire manufacturer LPG models are supplied specifically for use with LPG or LPG kits can be purchased separately to convert the natural gas burner to use LPG.

Cookers & Hobs
City Gas offers an installation service for all types of cookers & hobs.
If you are moving home we can also disconnect your existing cooker and cap the gas supply.
On completion we will test the gas appliance working pressures and the soundness of the gas supply pipework.
We also install cooker safety chains and stability brackets for free standing cookers which need to be installed to satisfy the gas safety regulations.
The connection of a gas appliance is much more than simply unscrewing the old cooker and putting in the new. No two appliances are the same and to fit them safely requires training and experience. Our engineers are qualified to standards laid down by the Council of Registered Gas Installers (CORGI)
Here’s what we do
1. Our engineer will make sure that it is safe to install your new gas appliance
2. We’ll make sure that the appliance is fitted with required safety clearances above and to the sides
3. Our engineer will extend existing pipe work up to 1.5m so that your gas appliance can be installed
4. Secure pipe work to the wall to ensure the pipes cannot be bent or broken
5. Fit a heavy-duty hose, connecting the cooker to the gas supply, ensuring the hose is not in contact with hot areas of the back plate
6. We'll ensure the product is level and can’t tip or fall by using a restraining bracket or chain
7. Perform a tightness check to ensure there are no leaks and a pressure check for the perfect cooking heat
8. Finally we’ll test the appliance and demonstrate its functions
