I would totally agree except it says warm air on the spa switch and if I feel the air it is warm like a blowdryer. The water still also blows through it but not on the hot air side on the other end of the heater tube.

I need to draw out the way the stock pipes with the electric heater are run but it looks really standard. Basically I looked at the electric heater plumming and looped from one end to my external gas heater. I get no flow but when I turn on the warm air switch it sounds like a vacuum and air rushes through the pipes to my gas heater. I am wondering if my spa stock setup has a hot wet and hot air side with the electric heater? And from my plumming mistake I plummed it to the hot air side. I haven't disconnected the electric heater and if I turn it on it runs water to one of the main jets. Is this normal to have hot air and hot water basically a dry and wet side to a heater sharing one pump for this? I have two pumps one basically connected to the heater and another one as a booster to other pipes basically recycling water. Also my gas heater is electronic ignition and I haven't seen it light yet since no water is being run through it. My main concern is to get water to flow to the heater.

Should I leave the existing heater in and just cut the output line from that to my as heater like this PUMP --- 220v heater-----------GAS HEATER inlet====GASHEATER OUTLET----- to spa heated jets / outlet I have done it like that now but I am having problems getting the water to flow to my gas heater. I think I am having pressure issues maybe I should undo the fitting on the heater side let water flow and then retighten the fitting.

I have an above ground spa that uses 220v. I was gifted a working Pentair-Minimax Heater 100,000 BTU Pool/Spa Heater - Natural Gas. The heater has a inlet and a outlet. I am thinking that if I turn the heater temp down and run the pipes to my gas heater it everything else should work the same. I have idenified the heater and below it almost connected is the pump for it. I am not sure if the water flows Drain - - Heater --- PUMP or Drain - - PUMP --- Heater. What part on the heater is the inlet and the outlet? Where do I hook up this to the spa and bypass the 220v heater? Has anyone here tried this before? Gas is cheaper then electricty. http://www.swimmingpoolsetc.com/pdf/minimax-ch-manual.pdf http://www.swimmingpoolsetc.com/PEN-460347.htm
