Error Code 81 (“No False Flame Detected”) indicates the unit has successfully verified the absence of unintended flame signals. Normally, this is a diagnostic message rather than a fault.
Usually, Error Code 81 doesn’t require any homeowner intervention. However, if this code appears frequently or if your system isn’t performing correctly, it’s essential to seek professional advice to rule out underlying issues.
