Beckett CG10 Manuel D’Utilisation

CG10 Burner Manual

Initiate – The primary control enters the INITIATE 
sequence when the control is fi rst powered on or 
power returns after an interruption. The initiate 
sequence is a ten second delay during which the 
control verifi es line voltage stability. 
Standby – The control enters STANDBY until the 
limits, operating limit control, burner switch, and all 
microcomputer-monitored circuits are in the correct 
state.
Load demand – Operating limit control contacts 
close on drop in temperature (or pressure) and 
initiates the start sequence.
Prepurge – The control will signal the PREPURGE 
sequence when the airfl ow interlock and all 
switches are in the correct state. The Prepurge 
sequence is the amount of time the blower motor 
runs prior to the ignition start sequence. Timing for 
the Prepurge sequence is determined by a card 
mounted inside the control module (typically 30 
seconds).  
Trial for ignition (TFI) – After the Prepurge 
sequence has timed out, the ignition and main gas 
valves will be energized.  Because the burner has 
direct spark ignition for the main fl ame, the fl ame 
must be established and detected by the control 
within 4 seconds or lockout will occur.  
Run – With a fl ame established and the control 
continuing to detect a fl ame, the burner will operate 
in the RUN mode until the load demand is satisfi ed 
or a limit opens. 
Load Satisfi ed – The fuel valves are closed.  After 
a 15 second post purge, the burner switches to idle 
until the next call for operation.

This operation sequence is 
typical and for reference only. The 

primary control could vary, depending on the customer 
specifi cation and code requirements.  For the specifi c 
operating sequence that applies to your installation, 
consult the appliance manufacturer’s directions, wiring 
instructions, and control manufacturer’s literature 
supplied with your burner.

This burner must be installed and prepared for start-
up by a qualifi ed service technician who is trained 
and experienced in commercial gas burner system 
installation and operation.
Do not attempt to start the burner unless you are 
fully qualifi ed.
Carefully follow the wiring diagrams, control 
instruction sheets, fl ame safeguard sequence 
of operation, test procedures and all appliance 
manufacturer’s directions that pertain to this 
installation.
If any of these items are not clear or are unavailable, 
call Beckett at 1-800-645-2876 for assistance.

Always verify the primary control has a 4-second fl ame 

establishment period by carefully following the control 

manufacturers’ confi guration instructions.
Example: Honeywell RM Series requires clipping and 

removing the JR1 resistor.
