If problems are found during the catalyst activity test, you shall replace the catalyst bed or take other corrective action consistent with the manufacturer’s recommendations.

NR 465.48(8)(b)4.b.b. Monthly external inspection of the catalytic oxidizer system, including the burner assembly and fuel supply lines for problems and, as necessary, adjustment of the equipment to assure proper air-to-fuel mixtures.

NR 465.48(8)(b)4.c.c. Annual internal inspection of the catalyst bed to check for channeling, abrasion and settling. If problems are found during the annual internal inspection of the catalyst, you shall replace the catalyst bed or take other corrective action consistent with the manufacturer’s recommendations. If the catalyst bed is replaced and is not of like or better kind and quality as the old catalyst, then you shall conduct a new performance test to determine destruction efficiency according to sub.
