13. A sediment trap shall be installed when REQUIRED by the manufacturer of an appliance
Answer: C
A sediment trap shall be installed as close to the inlet of the equipment as practical.
Installing a sediment trap as close to the inlet of the equipment as practical is crucial for ensuring that any sediment or debris in the gas supply is captured before it can affect the appliance's operation.
A) at the outlet of the meter
Installing a sediment trap at the outlet of the meter is not ideal because it does not address the sediment that may enter the system before the meter. The purpose of a sediment trap is to prevent debris from reaching the appliance, necessitating its placement nearer to the equipment.
B) every 25 feet
While spacing sediment traps every 25 feet might seem logical in certain installations, it does not align with the requirement for positioning the trap as close to the inlet of the equipment as practical. This distance may not effectively capture sediment that could impact appliance performance.
C) as close to the inlet of the equipment as practical
This option is correct because it emphasizes the importance of positioning the sediment trap near the appliance inlet. Such placement maximizes the effectiveness of the trap in preventing sediment from entering and potentially damaging the equipment.
D) they are not required if the gas supply is clean and dry
This statement is misleading, as sediment traps are still recommended even if the gas supply appears clean and dry. It is a preventative measure to ensure that any unforeseen debris does not compromise appliance performance.
Conclusion
The requirement to install a sediment trap as close to the inlet of the equipment as practical is essential for protecting the appliance from sediment-related issues. Other options either misinterpret the requirement or suggest ineffective placements, demonstrating that the correct answer is the most logical and effective solution for maintaining appliance integrity.
