Note: Communication signals from the remote display are superimposed on the flame signal test
jack. During a valid flame On condition these communication signals will appear to be negligible in
comparison to the flame signal (if measuring the flame signal with a DVM for example). When flame
is off, the
display communication signals or display “discover” signals will appear prevalant on the flame sig-
nal test jack. Use of an analog DVM will mask this phenomenon to an extent.

Do not ground the shield to terminal GND.
Note: Unshielded sensor wiring must not be run in common with other wires; it must be run in sepa-
rate conduit. Multiple flame sensor wiring must not be run together in a common conduit or wire-
way. Use #14 to #18 AWG wire suitable for 90°C (194°F) and 600 volt insulation, and run each pair
of leads in its own shielded cable. Multiple shielded cables can be run in a common conduit.

WARNING: Incorrect sensor installation may cause the sensor to generate a false flame sig-
nal, causing unburned fuel to collect in the combustion chamber. The result can be explo-
sions, injuries and property damage. Be certain that the flame sensor detects only pilot and
main flames, not glowing refractory, burner or ignition parts.
