What is a potential hazard of improperly installed pool heaters?

Improperly installed pool heaters can create significant hazards, including the potential for explosion and suffocation. This can occur due to various factors associated with gas heaters, such as gas leaks, which may result from faulty connections or inadequate venting. If gas accumulates in an enclosed space and is ignited, it can lead to an explosion, posing serious risks to both individuals and property.

In addition to the risk of explosion, improper venting of gas heaters can lead to the build-up of harmful gases like carbon monoxide. This can create a suffocation hazard, especially in areas with limited air exchange. Ensuring that pool heaters are installed correctly is crucial for maintaining safety and preventing these dangerous situations.

While other hazards related to pool safety, such as water contamination or equipment corrosion from chemicals, are also important to consider, they do not directly connect to the immediate dangers associated with poorly installed heaters like explosion and suffocation risks do.
