Once you've decided on the fireplace type, you must also decide on safety, venting and energy efficiency options.
- All natural gas fireplaces sold in Canada are certified to an approved CSA safety standard. This includes requirements for safely shutting down if loss of flame occurs.
- As of January 2015, all new fireplaces must include a mandatory safety screen to reduce the risk of burns.
Vents remove combustion gases from your natural gas fireplace to the outdoors. A chimney is not required, but an appropriate form of venting is. Your retailer or Technical Standards & Safety Authority (TSSA)-registered contractor can help you select the vent type for your new fireplace.
Natural draft venting
This venting style takes advantage of the fact that hot air rises up a vertical chimney. Natural draft fireplaces draw air for combustion from inside the home and vent combustion exhaust to the outdoors.
- A masonry chimney must be lined with a stainless steel liner to meet venting requirements. If you don't have a chimney, you'll need a B-vent.
- You'll also need a Draft Hood/Draft Diverter, to isolate the fireplace burner from outdoor wind effects and prevent back drafts.
Direct venting for greater efficiency
The fireplace draws combustion air from the outdoors through one pipe and returns the combustion gases to the outside through another pipe. A chimney is not needed.
- A glass panel is critical for keeping the combustion system sealed from the home, maintaining high efficiency and indoor air quality.
- Unlike natural draft venting, no air from your home is used for combustion, which makes this venting option more energy-efficient.
Power venting saves you money
Power venting uses an electrical fan to remove combustion gases from the fireplace.
- This provides a variety of venting options - horizontally, vertically or a combination of both.
- Because power venting controls the venting process, less heated air is used compared to chimney venting.
Pilot light options
A pilot light ignites the main burner of a natural gas fireplace. There are two options:
- Continuous or standing pilot - the benefit is that your fireplace will function and warm your home even if there's a power outage.
- Intermittent pilot that is turned off and on by a thermostat or by the homeowner control. Can operate during a power outage if equipped with a battery backup.
Control the heat
- A variable-setting control or thermostat gives you the freedom to adjust the amount of heat coming out of your fireplace.
- Variable-speed fireplace fans control the airflow from the fireplace.
