What is the primary concern when installing a water heater?

The primary concern when installing a water heater is ensuring proper ventilation for combustion gases. This is particularly important for gas-powered water heaters, as they produce combustion gases, including carbon monoxide, that can be hazardous if not properly vented. Adequate ventilation systems allow these gases to be safely expelled from the living space, minimizing health risks associated with carbon monoxide exposure and ensuring compliance with safety regulations.

Proper ventilation helps to maintain air quality and protects inhabitants from dangerous situations. Without adequate ventilation, there is a risk of gas buildup, which can lead to life-threatening conditions. Therefore, when installing a water heater, technicians must prioritize proper venting solutions that meet local building codes and safety standards. While other factors like insulation, accessibility for maintenance, and water quality are also important, they do not pose an immediate safety hazard like inadequate ventilation can.
