Question about Hayward H Series Pool & Spa Heater 400k Btu Propane Gas Milivolt Ignition H400p1
If you have automatic valves that switch over to run the spa, make sure that the valves turn completely to where they are supposed to be. Normally it will be about 180 degrees from where they are when in pool mode. If you have to change the valves over manually, make sure they're in the proper position. The only time this can happen is if the valves are not in the right position allowing the heated water to return to the pool. The thermostat on the heater will heat the water to the prescribed temperature no matter how you have the valves set. So if you place it on spa mode, it will heat whichever body of water that is flowing through it to that temp. If you have an automation system, double check the valves. That is probably where your problem lies.
