I have 6 months to figure this.

While fixing ac, costomer wants me to fix problem before winter.

Carrier 80% power draft. HO complains furnace limit trips off during windy conditions. Claims this happened after reroof and replaced Bvent pipe.

8 feet of bvent with one 90 and cap.

Two service companies said termination cap needs to be extended higher. It is 12" off roof.

I cannot believe this is the solution with a power induced burner.

Anybody seen this as a reason to trip off limit.
