I just moved into a house with a pool set up by the prior owner. It has a natural gas Pentair heater. The heater has an exterior thermostat and power switch.
The AC is also powered on off by a remote switch.
The gas line has an on-off valve.
Here's my question:
How do I shut off the heater safely?
I was told that the heater cannot be on when the pump is not running. Is this true? I also know people who leave their heaters on all the time.
My concern is the gas - if the heater is shut off remotely, what would keep the gas from building up? It's probably a stupid question, but the natural gas makes me nervous, yet I can't imagine having to open and close the gas valve all the time.
