Section: Sequence of Operation

continuing to detect a flame, the burner will operate in the RUN mode until the load demand is satisfied or a limit opens.

○For High/Low control wiring (Figure 9A), if terminals RC1 and RC2 are jumpered, the burner operates in the Low-High-Off mode. The burner starts at Low and goes to High after the flame stabilization period. Flame is extinguished when the load is satisfied or a limit opens, and the burner is sent to post purge.

○For High/Low control wiring (Figure 9A), if a high / low control has been wired between terminals RC1 and RC2 the burner starts at Low and is released to go to High after the flame stabilization period. It can repeatedly cycle between low and high as necessary to meet load demand until the load is satisfied or a limit opens, and the burner is sent to post purge.

○For modulating control wiring (Figure 9B), the burner starts at Low and is released to modulate after the flame stabilization period. It can modulate between low and high as necessary to meet load demand until the load is satisfied or a limit opens, and the burner is sent to post purge.

8.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.
