8. After the minimum pilot test is completed satisfactorily, increase the pilot flame to normal size,
and observe that the main flame is properly established during a normal cycle (“Run-Check”
switch in the “Run” position).
Flame Failure Test
1. Temporarily connect spark ignition and pilot valve to Terminal #3.
2. Initiate a normal startup.
3. Manually shut off all fuel and observe the loss of flame signal on the test meter.
4. If flame signal does not reduce to zero within the flame failure response time of the control
(F.F.R.T. determined by selection of amplifier), verify that the UV flame detector is not actuated
by the spark. If spark is detected, a metallic shield or relocation of the UV detector sight pipe is
required.
5. IMPORTANT: When the test is completed, reconnect the spark ignition to Terminal #4.
Recommendation
Periodic Safety Check: Test the complete flame safeguard system at least once a month. This test
should verify flame failure safety shutdown and positive fuel cutoff when the fuel valve is de-ener-
gized.
MAINTENANCE
UV-eye scanner: The UV tube must be kept clean. Use a clean cloth with detergent as often as oper-
ating conditions require. Remove any residual detergent.
ROTATION
It is recommended that units purchased as spares be rotated periodically, so that each unit will be
placed in operation every 90 days.
