Clear Snow from Vents

 
Make sure that all snow, ice and other obstructions are removed from your venting systems during the winter months. 
 
Keep an eye on outdoor vents, gas meters and chimneys for ice or snow buildup. Abnormal snow and ice build-up may block gas appliance exhaust and combustion air vents (especially those side wall vents exiting close to ground level) causing appliance failure as well as possible buildup of Carbon Monoxide.
