How can improper installation affect combustion appliance performance?

Improper installation of combustion appliances can significantly impact their performance by leading to inefficient operation and creating safety hazards. When an appliance is not installed according to the manufacturer’s specifications or building codes, it may not function as intended. This can result in incomplete combustion, where fuel does not burn completely, leading to the production of carbon monoxide, a dangerous gas. Additionally, improper venting can cause backdrafts, where harmful gases are pulled back into the home instead of being expelled outside. This combination of factors not only reduces the appliance’s efficiency—resulting in higher energy costs—but also raises serious safety concerns for the occupants of the home, making it crucial to adhere strictly to installation guidelines.
