What must be done during the installation of a gas log fireplace?

Make sure there is a metal mesh screen in front of the fireplace
Secure the chimney damper in the open position
Install a pressure regulator
Install a metal chimney liner

The correct answer is: Secure the chimney damper in the open position

During the installation of a gas log fireplace, securing the chimney damper in the open position is essential for proper ventilation. This step ensures that the hazardous gases produced during combustion can safely exit the home. An open damper allows for the efficient dispersal of these gases, minimizing the risk of carbon monoxide buildup, which can pose serious health risks to occupants. Furthermore, most gas log fireplaces are equipped with their own venting systems or utilize existing chimneys, and keeping the damper open during installation and operation promotes adequate airflow. Proper ventilation is a fundamental safety requirement when dealing with gas appliances, and this action is a critical component of that safety protocol. The other options, while related to fireplace installation, are not universally required or applicable in every installation scenario, making the securing of the damper a more fundamental aspect to prioritize for safety.
