Windy day, wind blowing directly at a fan assisted horizontal flue.
During a flue integrity test O2 is 19% 10ppm of CO
The very next day without the wind the flue integrity is fine.
This is the first time I've ever had this but I would guess its a common issue?
I wouldn't say the flue is particularly susceptible to wind as its opposite the prevailing but a plume management would actually cause more issues with keeping it away from the fabric of the building.
