Besides using an angle finder, what additional instruction should you follow when aiming a flame detector?

• A. Ignore manufacturers instructions
• B. Refer to the manufacturer's published instructions
• C. Rely on field experience only
• D. Ask a supervisor

Answer: (B)

Aiming a flame detector requires following the device’s manufacturer’s published instructions. The manufacturer specifies the exact aiming geometry, field of view, mounting height, and distance to the flame, as well as the required tests and calibration steps to verify proper operation. Using an angle finder helps with the rough angle, but without consulting the manufacturer’s instructions you won’t know the precise alignment, sensitivity settings, or verification procedures necessary for reliable detection and to meet safety and code requirements. Relying only on field experience or asking a supervisor can be part of the process, but the definitive guidance comes from the manufacturer’s published instructions.
