If you notice any of the following warning signs, you’ll want to get your appliance serviced right away:
- The gas appliance is not working properly
- The appliance is burning with a lazy yellow flame rather than a crisp blue one
- Black marks/stains are evident around the gas appliance
- The pilot light keeps going out
- There is increased condensation in the room
What’s the difference between a safety check and a service?
Prior to any work being carried out it is important to agree with your registered engineer their scope of the work so that everyone is clear. For example, there are differences between an appliance service and a safety check and equally between a safety check of appliances and a safety check of the whole installation, which includes all pipework and appliances.
What is an Appliance Safety Check?
An appliance safety check at a minimum includes all of the checks and tests to ensure the appliance is safe to operate, for example:
- It is correctly set and adjusted to ensure the gas is burning correctly
- It is of a type suitable for the room in which it is located
- It is physically stable, securely fitted and properly connected to the gas pipework
- There is an adequate and permanent air supply suitable for the appliance type installed
- Any flues or chimneys are operating correctly
- All safety devices function correctly
What is an Appliance Service?
An appliance service will include all of the above checks and tests and any other specific checks, for inspection and/or cleaning of the appliance as specified and detailed in the appliance manufacturer’s instructions. This may include:
- If appropriate, an analysis of the combustion exhaust gases to ensure the appliance is burning the gas safely
- A check of the condition of the appliance including (but not limited to): the effectiveness of any seals, gaskets, the cleanliness of heat exchangers etc. and checking for any signs of heat or other distress
This is not an exhaustive list and servicing requirements will vary across appliance types and models.
Note: Some appliance servicing regimes provide an interim performance check (annual) to be used in order to determine the degree of dismantling the appliance and the level of servicing required.
What is a Gas Installation Safety check?
If a gas installation safety check (all appliances and internal pipework) is required or specified each appliance will need to be checked as outlined above and additionally:
- All accessible gas pipework is visually inspected to ensure the installation is in good condition, and;
- The gas pipework is tested to ensure there are no gas leaks
