Maintain Gas Products
Your safety is our top priority
Like your car, natural gas appliances operate at peak efficiency when they are properly maintained.
Annual maintenance by registered contractors
Union Gas recommends you have a Technical Standards& Safety Authority (TSSA)-registered contractor perform a yearly maintenance
check-up of your gas-fired equipment and venting system to ensure safe, efficient
- Adjustments, cleaning of burners, replacement of parts, repairs and
inspections of venting are jobs for licensed professionals who know the equipment
and the codes that must be followed.
- When calling for or agreeing to an inspection, ensure that the service provider uses licensed gas technicians to do an actual safety
inspection and ask for the gas technician's provincial certificate number and the
contractor's TSSA registration number.
- Find a list of TSSA-registered contractors in your area on the TSSA website.
Household Air Supply
Natural gas products need an unimpeded air supply in order to burn natural gas safely and efficiently. Some equipment has a pipe that brings outdoor air into the combustion chamber but some still use household air for proper burning of gas.
- Remember that other household appliances and systems also use air and exhaust it outdoors, all of which can reduce the amount of air available for your natural gas equipment.
- When weatherstripping and sealing your home to conserve energy,
provisions for adequate air and ventilation should be made at the same time.
- Stale air and smells that linger.
- Backdrafts from a fireplace or furnace.
- Lots of moisture and mould build-up.
- A pilot light that keeps going out.
