What is the primary risk addressed by proper termination height for gas vents on pitched roofs?

The primary risk addressed by proper termination height for gas vents on pitched roofs is fire hazards. When gas appliances vent exhaust gases, including carbon monoxide, it is critical that these gases are safely directed away from the structure and neighboring buildings. If the termination point of the vent is too low, it could result in flammable gas accumulating near the roof, creating a significant fire risk if ignited.

Proper termination height ensures that the exhaust disperses at a safe distance from the building's eaves and windows, thereby minimizing the chances of ignition and protecting the overall safety of the property. Adequate height also helps prevent wind from blowing the gases back towards the roof or into the home's living areas, further mitigating fire hazards.

While gas leaks, wind damage, and structural integrity are important considerations in the context of gas venting, ensuring proper termination height specifically addresses the risk of fire, making it the primary concern in this context.
