Here they share a tip on snow plugged exhaust pipes:
When getting alot of snowfall at once,one of the major issues that high efficient furnaces have is that the intake and exhaust pipes get plugged or covered under snow.
Be sure to check your venting first if your high efficient furnace does not come on.
Saskatchewan gas code says the venting shall not be below 18" when side wall venting,due to this fact of getting covered in snow as well if it penetrates the roof,it has to have proper clearance.
The last picture is a concentric vent kit,the exhaust shoots out of the middle and air is drawn from the sides.
This is a common problem for us is Saskatchewan due to the amount of snowfall we have at times.
If your furnace is showing a pressure switch code,more that likely this could be one of the issues
