Step by Step Instructions for Ensuring Easy Pool Opening

[baobao2013]

Hello,
I am a new pool owner and pool has a gas heater. my question is - should be pool heater be switched "on" in order for the water circulation?

Currently, the weather is still cool in my city, not ready for swimming yet, but I want to open the pool to get the water clear out. So I only need to circulate the water not really heat up the water, in this case, do I still need to get the pool heater switched "on". If I keep the heater in "off" - no display on the LED, can the water be circulated?

Thank you!

Normally the heater doesn't need to run for water to circulate through it, there is probably a flow switch in the heater which needs water to flow through before the heater will fire
Some systems may have a bypass so that the heater can be isolated for maintenance
