Heavy snow is coming with wind which will cause drifts. For those who have furnace and boiler exhaust flue discharges through the side wall of your house or building, typically a "direct vent" appliance, be aware these snow drifts may block the flue exhaust, intake or both. This will choke of the exhaust and trip the system. This also is true for on-demand water heaters and gas fireplaces as well as generators. So be mindful to check their surroundings. Pass this on to friends and neighbors. Once your system "trips" of a blocked flue, some you may be able to reset by turning the system off for a couple seconds, then back on. Some of you may need a service person to reset. Good luck and be safe.
