Introduction
The control then powers the ignition electrode and initiates flame. The UV scanner and control confirms flame
presence and the burner progresses to main-flame operation. Main flame continues while flame is proven; the
external limit switches confirm good operating conditions, and a call for heat exists.
During main flame, the LMV37 receives a modulation input signal from a separate modulating controller that
directs the LMV37 to provide more or less heat. When the call for heat is satisfied, the LMV37 moves the gas
metering valve to the low-fire position and deenergizes the safety shutoff valves thereby shutting down the
combustion process. A post-purge period follows, and the heat exchanger is purged with air. After post-purge, the
burner returns to standby mode.
