Seal this hole when testing is complete. - Page 16 1.60 – 1.75 NOTICE The NX burner has a reduced diameter air tube, precision-designed air throttle cup and combustion head for improved performance. This design provides very accurate control of the air/fuel ratio, but the light reaching the cad cell through small holes in these components is limited. Because of this, the average cad cell resistance may be higher than conventional burners with larger openings.
