the two 90◘ on top are temporary to protect from rain.
Oil heater in garage, long, 5" dia flue coming out side of house.
without two 90° elbows on top and without the lower elbow and without the 4' vertical I get 0.005 wc draft. I need 0.02 to 0.035 wc draft. I might install a draft inducer fan inside the garage. Either that or secure the 4' vertical and put a flue cap on top.
Im not interested in laws or regulations. Ive read them all.
