Main Burner Flame pattern
The main burner flame will be completely yellow.
Main Burner Flame Ignition and Extinction
When the main burner is ignited it will take a few seconds for the full flame pattern to develop.
When the main burner is extinguished it will take a few seconds for the flames to disappear. It is normal to have the flames burn down
near the rock wool, as the remaining gas is burned.
MAIN BURNER FLAME CHARACTERISTICS
Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper
