The ventilation pipe reaches the outside only a meter above ground level and my neighbors, who do a lot of snow clearing, always cover up the pipes.
Always I come to Imagine and use a shovel to clear the pipe.
But, this week was very bad and it took me a long time to dig out the snow at the side of the building.
So, I took photographs and the Monday evening student Yoshiko helped me to make a sign: Please don't dump snow here on the stove pipe!
The heater has an alarm bell, which rings if the ventilation is blocked - but it isn't safe to cover the pipe.
