It’s getting exasperating and maddening. Have had two HVAC/plumbing companies out to no avail. C-1 is a venting blockage error code, the PVC vent pipe (2”) has been pulled apart and checked twice now, the intake examined for debris fallen on the burner etc. everything checked. Tried the automatic air/fuel mix calibration, fails every time at the 2nd stage. B-W thinks maybe a bad control panel/logic board. Last HVAC company feels too many elbows for the length of vent pipe run and/or too narrow a PVC pipe (should be 3” instead of 2”). The unit is only 1 year old. I’m getting desperate and tired of walking down 4 flights of stairs every morning to re-set it, along with 2-3 more times during the day and again before bedtime. Any insights?
