Clear your vents
Snow and ice can damage gas meters and pipes. Use a broom to keep gas service equipment clear during the winter.
Vents for gas appliances must also be cleared following a major snow or ice storm to enable proper venting and prevent carbon monoxide accumulation.
For sidewall-vented appliances such as direct vent furnaces, fireplaces, tankless water heaters, etc., do not allow the outside vent terminal to be blocked or obstructed by vegetation, ice, snow or any other materials. Blocked or obstructed vents can cause carbon monoxide to back-up into the building.
For new sidewall-vented appliances always follow manufacturer installation instructions and adhere to all codes such as: mechanical, building, city, etc.
