Proper flame detector installation is the basis of a safe and
reliable flame safeguard installation. Refer to the instructions
packed with the flame detector and the equipment
manufacturer instructions.
Keep the flame signal leadwires as short as possible from the
flame detector to the wiring subbase. Capacitance increases
with wire length, reducing the signal strength. The maximum
permissible leadwire length depends on the type of flame
detector, leadwire and conduit. The ultimate limiting factor in
the flame detector leadwire is the flame signal (see Table 6).
