What is the consequence of operating a gas appliance without proper adjustments at altitude?

Operating a gas appliance at high altitudes without proper adjustments can significantly affect the combustion process. As altitude increases, the atmospheric pressure decreases, leading to a reduced amount of oxygen available for combustion. This change can result in incomplete combustion, which manifests as a risk of insufficient combustion.

Insufficient combustion typically leads to the production of harmful gases, such as carbon monoxide, which can pose serious safety hazards. It can also result in an increase in fuel consumption, as the appliance may not operate efficiently under these conditions. Proper adjustments, such as recalibrating the burner for the specific altitude, are critical to ensure adequate combustion and safe operation of gas appliances. This adjustment optimizes the amount of gas and air mixed for efficient combustion, preventing these risks associated with operating at altitude.
