Which of the following is a reason for obtaining a variance before appliance installation?

Obtaining a variance before appliance installation is primarily important to ensure compliance with code regulations. Building and safety codes are designed to protect the public, ensure safe operation of appliances, and set standards for installation practices. A variance is typically sought when specific guidelines cannot be strictly adhered to due to unique circumstances on the installation site. By acquiring a variance, the installer demonstrates compliance with the intent of the regulations even if the specific requirements are adjusted. This process often involves a thorough review and approval by relevant authorities to ensure that any alternative methods will not compromise safety or performance standards.

While adhering to warranty requirements, avoiding additional costs, and simplifying the installation process may seem beneficial or relevant, these factors are not the primary reasons for obtaining a variance. Warranty requirements are typically addressed through proper installation per manufacturer guidelines, while potential costs are more related to financial planning rather than safety compliance. Simplifying the process might be a secondary benefit but does not align with the overarching goal of ensuring compliance and safety in accordance with legal regulations.
