Ontario's fire marshal is warning owners about the pilot light in some models of gas-fueled fireplaces.
Jon Pegg has carried out several investigations involving the Napoleon GD3200 propane gas fireplace and the Regency Ultimate U37 and U39 Direct Vent gas stove fireplace.
If you own one of those models, Pegg says you should turn it off and call your dealer to arrange for a repair.
The problem is the gas can accumulate in the fireplace, and when the user attempts to light it, it can explode.
The pilot light burners become blocked by dust or dirt, gas valves can stick, burner ports can become blocked by misplaced decorative features, or the vents become blocked.
"As a result of these investigations, we determined that too many Ontarians have been injured while trying to safely light their gas fireplace," said Pegg. "These injuries can be prevented. Working with the Technical Standards and Safety Authority, we have identified design deficiencies in some gas fireplaces, and consumers should take preventative steps if they have these appliances in their homes."
Serious injuries have been reported.
"Gas fireplaces and all fuel-fired appliances should be inspected and cleaned annually by a certified technician to reduce the likelihood of gas accumulation and explosion," read a release from the Office of the Ontario Fire Marshal.
