using a 40VA transformer like the R76734700 to replace a lower VA-rated part is acceptable as it provides more capacity for the 24V load

This is typically caused by a dirty flame sensor or a faulty gas valve

Precision Heat Management: Regulates output power from low to high detents with a calibrated 5% input at the low setting for simmering operations

Includes a 3-inch insertion length for optimal thermal response in various plenum configurations

provided the ambient temperature and humidity remain within the 5% to 95% non-condensing range
