For which type of appliance is the installation explicitly stated to adhere to the terms of listing?

The installation of pellet fuel-burning appliances must adhere to the terms of their listing because these appliances are specifically designed to operate safely and efficiently when installed according to the manufacturer's specifications. The listing provides critical information about the construction, performance, and installation requirements that ensure the appliance operates correctly and adheres to safety standards.

Pellet fuel-burning appliances rely on unique combustion and ventilation characteristics that are defined during their approval process. If they are installed outside these parameters, it could lead to unsafe operating conditions, such as improper venting, which can increase the risk of carbon monoxide buildup or fire hazards.

In contrast, while vented appliances, portable heaters, and solar panel systems also have installation guidelines, the explicit requirement that an installation adhere strictly to the terms of listing is particularly emphasized for pellet fuel-burning appliances due to the complexity of their operation and the critical safety aspects involved. This distinction is significant in maintaining compliance with code as well as the safety of the appliance during use.
