Under sizing is a common problem found with oil furnace vent connectors. True or False?

The statement is true. Undersizing of vent connectors in oil furnace systems is indeed a common problem. Proper vent sizing is crucial for efficient operation and safety. If the vent connector is too small, it can restrict the flow of exhaust gases, leading to poor combustion, increased carbon monoxide production, and potential backdrafting issues. Vent connectors must be sized according to manufacturer specifications and local codes to ensure that the system operates safely and effectively, maintaining proper draft and preventing furnace performance problems. Adequate vent sizing allows for an unobstructed path for exhaust gases to exit the home, which is essential for the safe operation of an oil furnace.
