For which of the following is a sediment trap not required?

• A. Water heaters
• B. Furnaces
• C. Ranges
• D. Boilers

Answer: (C)

A sediment trap is designed to collect debris and sediment from gas lines to prevent it from entering appliances and causing damage or malfunctions. While water heaters, furnaces, and boilers require sediment traps because they use gas and can be negatively affected by sediment buildup, ranges do not typically require them.

Ranges usually have smaller gas supply lines and are less susceptible to sediment issues, as they function primarily for cooking and do not rely on the same pressure and volume that larger appliances like water heaters and boilers do. This makes ranges the exception in this case, which is why the correct answer indicates that a sediment trap is not required for them.
