Performed furnace start up; started by setting up the humidifier at the prestige thermostat, I then went and inspected the exhaust and intake pvc ensuring all connections were secured, I then did a leak search on the gas line, I cycled the system on and checked gas pressures and did make adjustments on both stages, lastly performed a combustion test verifying no CO in the airstream. This system is currently operating normal and heating at 58 degrees at this time job complete.
