Bard part 9043-402 is an OEM California NOx screen used on certain Bard gas heat wall-mount and packaged units to help the burner system meet California NOx emissions requirements. Replacing a damaged or missing screen helps maintain proper combustion airflow characteristics and supports reliable ignition and steady heating performance, which can reduce nuisance lockouts tied to flame or combustion issues. This is a direct-fit Bard replacement part intended to match the original equipment configuration, so confirm compatibility by checking your unit model and serial information in the correct Bard service literature before ordering.
* Orders less than $50 may incure a minimum order fee.
