Sequence of Operation

(Typical for RM7897A flame safeguard primary control)

1.Initiate – The primary control enters the INITIATE sequence when the control is first powered on or power returns after an interruption. The initiate sequence is a ten second delay during which the control verifies line voltage stability.

2.Standby – The control enters STANDBY until the limits, operating limit control, burner switch, and all microcomputer-monitored circuits are in the correct state.

3.Load demand – Operating limit control contacts close on drop in temperature (or pressure) and initiates the start sequence.

4.Prepurge – The control will signal the PREPURGE sequence when the airflow 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).

5.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 flame, the flame must be established and detected by the control within 4 seconds or lockout will occur.

6.Run – With a flame established and the control continuing to detect a flame, the burner will operate in the RUN mode until the load demand is satisfied or a limit opens.

7.Load Satisfied – 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 specification and code requirements. For the specific operating sequence that applies to your installation, consult the appliance manufacturer’s directions, wiring instructions, and control manufacturer’s literature supplied with your burner.

Prepare the Burner for Start-up

Professional Installation

& Service Required

Incorrect installation and mishandling of start-up could lead to equipment malfunction and result in asphyxiation, explosion or fire.

yThis burner must be installed and prepared for start- up by a qualified service technician who is trained and experienced in commercial gas burner system installation and operation.

yDo not attempt to start the burner unless you are fully qualified.

yCarefully follow the wiring diagrams, control instruction sheets, flame safeguard sequence of operation, test procedures and all appliance manufacturer’s directions that pertain to this installation.

yIf any of these items are not clear or are unavailable, call Beckett at 1-800-645-2876 for assistance.

Delayed Ignition, Explosion

and Fire Hazards

This is a direct spark ignition burner and by code requirements must have a primary control with a 4-second flame establishment period. Exceeding 4 seconds could result in delayed ignition, explosions and fire.

Always verify the primary control has a 4-second flame establishment period by carefully following the control manufacturers’ configuration instructions.

Example: Honeywell RM Series requires clipping and removing the JR1 resistor.
