When sweeping gas appliances, they should be set to which mode?

Off
Direct vent
Pilot
Main

The correct answer is: Pilot

When sweeping gas appliances, they should be set to pilot mode. This setting is important for several reasons. When the appliance is on pilot, it allows the technician to safely access and clean the burner assembly without the risk of gas igniting and causing an explosion or fire. Additionally, the pilot light provides a small flame that can help in ensuring that any accumulated gas is properly burned off during maintenance. Using this mode minimizes potential hazards associated with having the appliance in main or direct vent positions, where greater volumes of gas are present, posing increased safety risks. Thus, pilot mode is the safest and most appropriate choice for sweeping gas appliances.
