Care and maintenance of LPG appliances


After their installation, gas appliances become part of the house and tend to be neglected and forgotten until something goes wrong or they cease to function as they should. Like other machines, gas appliances become inefficient, unreliable, and may even pose a safety hazard if not maintained in top condition.
Gas heaters are heavy users of LPG so any problems are usually easily detected, these may include, a smell of smoke with sooting, eyes running, breathing difficulties or simply using more gas than they should.
To maintain their safe use and condition, appliances require regular servicing by trained competent and appropriately licensed servicing agents. Common problems where appliances are not regularly serviced include:
Burners in water heaters or space heaters can become blocked with dust or lint leading to sooting up the heat exchanger and flue passageways
Air filters, air ways and fans can become blocked by lint and dust, leading to overheating and burner problems
Safety controls can wear out and fail
High release of emissions resulting from incomplete combustion causing a heavy smell of hydrocarbons and potential respiratory problems.
Always follow the manufacturer’s service plan and note the date of service on the service sticker.

When to service

Manufacturers recommend service periods for their appliances, this information may be located in the users manual for the appliance. These should be closely observed.
Generally it is recommended that appliances are serviced at least every two years.

Preparing for winter

Most appliances are used more during periods of cold weather. Checking appliances before the cooler weather arrives ensures that all your gas appliances are in good working order and you will be able to enjoy a warm and safe winter while reducing your gas bills.
Space heaters may not have been used since the last cold weather period. To get the most from heaters, the following should be done in preparation for winter:

When using a flue-less heater, ensure that the room is adequately ventilated
Check that permanent ventilation openings are not blocked
Make sure that roof insulation is not obstructing a heater in the roof space
Check the outer case of your space heater. Is it discoloured? Discolouration is an indication of a faulty flue and that it is time to have it checked by a licensed gas fitter
If you have difficulty re-lighting the gas appliance, call a licensed gas fitter
Check the heater - a yellow flame can indicate that your heater is not running correctly and needs servicing
Have your central heating serviced, including the fan section, before you use it. Check that sufficient warm air registers are open, as recommended by the manufacturer.
