The MITCO N29-26M is a replacement smoke test paper tube containing 50 strips, designed for use with the Smoke Check combustion smoke tester. HVAC technicians and oil burner service professionals rely on smoke test paper to measure the smoke number of a combustion system during routine tune-ups and annual maintenance. The test works by drawing flue gas through the paper strip using a pump. The resulting stain on the paper is then matched against a standardized smoke scale to determine how cleanly the burner is firing. A clean, efficient burn produces a lighter stain, while excess soot or incomplete combustion leaves a darker mark. This reading helps the technician adjust the air-to-fuel ratio, clean or replace nozzles, and bring the system into compliance with efficiency and emissions standards. The MITCO N29-26M strips are a direct replacement consumable for the Smoke Check tester, ensuring consistent and accurate readings job after job. Each tube holds 50 individual strips, giving technicians enough material to complete multiple service calls before needing a resupply. The strips measure approximately 6 and 5 eighths inches in length, 1 inch in width, and 5 eighths of an inch in height per tube. Keeping replacement smoke test paper on hand is essential for any heating contractor, oil burner technician, or boiler service professional who performs combustion analysis as part of seasonal startup or service calls. Using the correct OEM-specified paper ensures compatibility with the tester and reliable smoke number results every time.
