For Nonthreaded Pipe	2L-1. Normal Operation
	The Hi-E2pool heater operates automatically. It

	temperature settings on the FlexTemp control panel on
	the front of the heater. The heater has internal controls
	to sense adequate water flow and to handle any
	abnormal condition.
	Normal operation is as follows:
	1. The pool/spa system filter pump provides
	water flow. A pressure-flow switch in the
	heater detects water flow and enables the

2.If the FlexTemp selector switch is set to "Pool" or "Spa", and if the water temperature is not warm enough, the FlexTemp control signals the combustion system to start.

3.The ignition control starts the combustion blower.

4.When the venturi pressure switch detects combustion air flow and when a suitable “pre-purge” time has been allowed, the ignition control energizes a “hot surface” igniter.

5.The igniter is allowed to reach ignition temperature, at which it glows bright red- orange. This is visible through the combustion chamber view port.

6.The gas valve is opened and gas flows into the combustion air. The gas/air mixture flows through the burner into the combustion chamber. It is ignited by the igniter.

7.The ignition control electronically senses successful ignition by “flame rectification”, and the gas valve is allowed to stay on. The igniter is de-energized.

8.The heater operates for as long as the FlexTemp control demands heat, subject to
