I had a Bryant system (355CAV + 186B + CNPVP) installed recently and it passed the code inspection. However, I just realized there is no trap on the evaporator coil drain line and I'm trying to figure out if my arrangement is as it should be.
For now, the attached drawing will have to do. My furnace is configured for upflow. There appears to be that internal trap on the furnace drain line but there is no trap on the evaporator drain line. The two drain lines merge into one which runs into the floor and then discharges outside near the ground.
Is this a proper way to drain such Bryant gear? The best way?
