What benefit does following manufacturer’s instructions provide during installation of gas appliances?

Following the manufacturer’s instructions during the installation of gas appliances is crucial for ensuring compliance with safety standards. When these guidelines are adhered to, they significantly reduce the risk of hazardous situations such as gas leaks, improper ventilation, and unsafe operating conditions. Manufacturers design their instructions based on extensive testing and regulatory requirements, ensuring that appliances function safely and efficiently within the prescribed parameters.

By complying with these directions, installers help maintain safety standards that protect both users and property. This adherence also helps in documentation for inspections and permits that may be required by local authorities, thereby reinforcing the safety measures established in the National Fuel Gas Code. While the other options offer potential benefits, such as warranty validation or potential cost savings, the main focus of the manufacturer's instructions is to uphold safety compliance, making it a fundamental principle in the installation process.
