Red Seal Gasfitter — Class A Practice Exam

How often should gas appliances be serviced?

1. At least once a year

2. Every two years

3. Only when there is a problem detected

4. Every five years

The correct answer is: At least once a year

Gas appliances should be serviced at least once a year to ensure they operate safely and efficiently. Regular maintenance is essential to check for any potential issues such as gas leaks, carbon monoxide production, and to ensure that the appliance is functioning correctly. Annual servicing helps to identify wear and tear, clean components, and comply with safety regulations, which together help prevent hazardous situations. It also contributes to the longevity of the appliances and promotes energy efficiency. While some appliances may experience fewer issues and might seem to function well without regular servicing, relying solely on the presence of problems can lead to unsafe operating conditions and potentially dangerous situations. Furthermore, servicing every two years, only when there is a problem, or every five years may increase the risk of prolonged exposure to unsafe appliances, which is why such schedules are not recommended for regular maintenance.
